@@muffinmonsta5302 back in the day, Jafro was the only channel that actually detailed the process of rebuilding an engine. I learned how to use specialized tools like bore gauge and micrometer from Jafro. Jafro shows the real struggle of real car guys. Most of the other shows fail to show the in between stuff.

He got me with the Colt. The kung fu sound effects when the was doin the trans tunnel. Killed me.

It's really... not much at all... It's a timing belt, water pump and gasket set, a wiring harness, handful of sensors, a 3" exhaust cutout, a cheap Amazon fuel system, about $700 worth of stereo equipment. That's about it... the water methanol kit was a gift from my stepdad, and the car was free. Everything else that went into it were used hand-me-downs and leftover scraps. Probably $3,000 tops?

And with minimum wage labor figured in he's around $50k or so...

We miss your videos Tom!

O heck yeah doood! It's even better when there's a good used 6-puck sprung clutch for your exact car sitting on the shelf in front of the dyno where you burned it up! Wait until you see how it comes back...

@@Jafromobile well now we are in suspense - don’t let us wait long.

Drastic changes coming this winter! Hilarity will ensue!

My 6500lb truck is a blast with that much power! My Elantra weighs 2650.

@@Jafromobile Your truck really weights 6500lbs?! in a gasser? my 2nd gen cummins only weights 400 more pounds! nuts! As a smart man once said "want to go faster add more power. Want to go faster everywhere? add lightness" I have no clue how much power my 1g with 2.3 stroker with a e3 16g and 3inch exhaust makes but it sure feels lightyears faster then any of my 2g's feel.....really need to get them tuned as well.

2013 F-150 SuperCrew. Last of the steel bodies. Gen 1 Coyote. When I was pulling the trailer for the previous video, I got worse gas mileage with the trailer empty than I did with it full. I got .1mpg less with it empty. I added 4,000lbs between the truck bed and the trailer and got better... I just... ?!?!?!? I know why now... but just *feels* wrong.

I have to get so much stuff out of my way to do this one... lol... I'm working on alternative means of speeding it up. I'm just as anxious as you are.

Oh yes, it's totally the bottleneck. 100%! I'm way off the compressor map here. It's still 150hp more than one wheel drive can use.

I learn something every time I work with Abe. Every time.

Thank you for noticing! It's literally what I do this for. I enjoy working very hard for my cardboard sign! ;)

40 PSI at idle, baby! Achievement unlocked!

This is the same advice I give other people, lol! I approached this using the scientific method, attempting to change only one variable instead of several. Matt and Abe have put a lot of work in to troubleshooting Omni sensors to the point where their discoveries led to them changing the product. This sensor is not an Omni, but it fits all the other criteria of your post... yes, it's a rescaled piece of ancient technology. And it's plugged into an even older ECU that has a 17.7 Hz refresh rate. lol!

@@Jafromobile Hahaha love that. I pretty much assumed that you knew everything I said, but at the same time if you say nothing at all, nobody will ever know anything! I definitely appreciate and enjoy watching your process.

@@802Garage Awww, don't give me too much credit! I just work here? lol

@@Jafromobile 😂 AND A LOT OF WORK IT IS!

FYI, I heard this... Thank you!

d'awwwww! I have to make a swivel mount for it now... that kinda does need to happen, but I don't know if it has enough weight to actually sway. It's so tiny and the dang thing has a rigid mount. I'm trying to get a 3D printed medallion for it to mount it on and to hide the 3V inverter.

​@@JafromobileIf it moves or shakes one bit I'm happy, I still can laugh about the battle between the elantra and the truck.

It's in the timeline, but I might take you up on that, lol! 1g or 2g?

@Jafromobile 2g gsx. Out of a 97 talon. Has no 1st gear. Sourced a good trans and tcase from a 96 i found but i was either gonna try and learn to rebuild it myself or send it out. If you're serious we can talk off RU-vid

Likely because of a leak. One of the reasons it's a bad place for this is because the diameter of the nipple is more than twice that of the MAP sensor. That means it's going to be a bad fit on either one end of the hose or the other. It's why I used a smaller hose that had to be painstakingly stretched over the manifold port, and worm-gear clamped onto the sensor side. If it starts farting over ? PSI or under # vacuum, then you basically brought the ants with you to your picnic. I was aware of this and took precautions for it that proved to hold up, but it's still a problem with such wildly-different-sized barbs.

I like this trend where I dyno it every time it gets a mod. New subwoofers? Put 'er on the dyno!

@@Jafromobile should be standart Test of cars and engines! :D

...why?!?!? Why dinchoo say something?!?!?!? LOL! :P

Actually that one's a leftover from Matt's pile. But indeed great things are happening right now with that Galant! You will see soon!

Happy to give you the tour! They're awesome! The kind of cars I would probably rewire if I had that resource available to me inside my shop... ...the correct answer is any of them, but still...

I agree! Not to shabby for a grocery getter!

Search "ECMlink 101 Initial checks". There may be something I did wrong, but in 2010, AFRest changed in an update and is no longer automatic. There is likely some user-supplied data there that I need to update, but Matt may have done it while he was in there. I haven't quit digging, I just fudged my MAP signal enough to get good pulls for now. It's 100% in the math somewhere. Abe's scope proved that.

Shhhh... hey, no spoilers!

@Jafromobile LOL hey you DO have to pull the trans to change the clutch after all 😉

Yeah for sure. I roll around in a pretty efficient engine these days (relatively speaking), and at an E60 blend without being hard into boost all the time, I don't particularly notice a big drop in fuel economy.

If you can't mount with the vacuum port straight down, you can perhaps also install the sensor on your 270°F cam angle sensor and burn it all off?

@@Jafromobile heat will kill it over time to. The firewall mount is good just rotate it so the nipple points toward the ground. The vacuum line also needs to be smooth flowing to it. You don't want allow it to build condensation and have it shove it up the line. You are also running methanol injection that is basically injecting steam into the intake. Long as you have good vacuum at idle the line should stay clear and with the sensor nipple pointing down it should keep water out. Ps I had linked a white paper for the sensor in an earlier post but it got flagged for spam

Old style but with a dyno instead of a track! I think the shop was a good move for the channel!

It depends on whether or not there's boost. Gains are exponential with boost, more so than it is with fuel type. Look at the differences between the wastegate pressure and high boost with 93 octane that I showed. Note the 117 foot pound of torque increase between start and finish after turning the boost up. So basically, I did previously did do that, and it's in the performance subwoofer video... but on a normally-aspirated car, 5-10% gains from it are typically pretty easy, and any increase in power is an increase in its overall efficiency. It doesn't look as impressive as a car that you can also turn up the boost on would look, but you'd still be able to tell.

The roll stopper mounts are windowelded. TPS would show on the log or the scope. I will totally get 400 out of this turbo before I quit it.

Your brain lit up the same brain cell addresses that mine did at one point. That's why it was so nice to have Abe here with the scope for a whole day of dyno pulls. There wasn't any noise in the input voltage or the sensor outputs, and if there was EMI or RFI, that scope would have found it.

​@@Jafromobilemy electronic mind kinda doubts the ECU/the ADC in the ECU. I would pull the ECU and replace any electrolytic cap that it uses. And I would send the logs to ECS tuning and ask for their opinion on what can amplify noise on the math section.

I've seen a few intake manifold mounted ones with even this particular sensor. Just had a grommet on the cast side for a gasket, and the nipple stabbed into it, secured with 2 bolts. No vacuum hose at all. Much cooler place than I was using, but I agree the firewall is a better home for it.

@Jafromobile interesting as my experience is euro gm stuff but can definitely see how that'd work on a normal setup. We can all agree the hyundai is far from normal! (For the right reasons of course)

I've got to have some garbage data in it somewhere. There might be something in the AFRest options I can adjust that will fix it. When I get the clutch installed, we'll be sure to continue sleuthing.

I can see it now... The o2 sensor gets the new MAP sensor's IP address, steals it's identity, plants some malware... the MAP sensor begins DDoSing its own port on the ECU. My Norton subscription has expired so now I'm at Best Buy talking to the geek squad tryna get this malware removed so I can get my car to start... ...and now all I get is ADS on my RADIO!!!

@@Jafromobile imagine hitting the accelerator to make some donuts in the parking lot, and the pedal wants you to first accept cookies. :-) I wish it was a joke, but my garage door updated it's privacy policy, and wanted me to click to agree to a very long legal contract written by corporate lawyers for the benefit of the corporation before it would let me into my house. This is why I have a new garage door opener.

​@@WilliamDye-willdyeI've actually had an idea similar to this for quite a while to make the dashboard of a car look like a circuit board with indicator lights for every function taking place. Purely aesthetic for like a showcar, but I just thought it would be fun. Also good for education if you will.

It might be, but don't forget what chassis this is! How impractical it is to turn a 30 year old 4-door Elantra into a race car? Much larger gains could be made just by putting all this in something else. That would actually cost less and be easier to do than a different ECM system at this stage. Some of the joy of this is not being a thoroughbred.

@@Jafromobile megasquirt systems aren't that expensive, and it might add some more life to the car. And yes, it's not a race car, but even if you don't want it to be, it's slowly evolving into one🤣🤣🤣

This would be one good reason, yes.

You're going to hate how easy I have it with the clutch. 1g/2g stuff ain't like yours. You've got a pull style clutch, not a pusher like DSMs do. People are freakin' out because I'm telling you this without you saying the word Evo... but on ol' blue it will be like the Hyundai. You'll need a F/W5M33 on that one. Don't try to do that with the KM210.

I missed part of this. Against Matt's best advice, I still have the kit active. It's complicated to explain why, but it's staying. Cliff notes include e85 isn't available everywhere, this car needs knock suppression with gasoline, it's a progressive controller with failsafes, I lose the failsafes without the controller, and, it was a Christmas gift from my dad.

@@Jafromobile gotcha, good to know. I am going to convert to flex fuel on the Evo eventually. Ole Blue will likely get that from the start, since we finally have E85 in my area now. I always wonder would it better to just run 93 pump with an additive?

Because this car was built entirely from used parts. No foolin'! It's a free car built from 3 people's spare scrap parts.

Certainly good advice. Matt and Abe actually helped Omni figure out what was going sideways, I just don't know where in the supply chain to get the new one? Could just be that I cooked it? If this one goes, I'll AEM next.

@@JafromobileThey seem to just glitch out randomly, even when mounted to the firewall. Changed manufacturer at some point maybe?

@@jdxnc04 The one I just got is not a Omni brand. Looks very similar, but it's someone else's? The spikes are happening somewhere in the math in the ECU. Has to be because we scoped every input used in it for anomalies and all the signals were clean. There were no fluctuations in any of the 5 or 12v sensor circuits or their outputs. None of the values except for AFRest and Injon show any fluctuations or spikes at all. AFRest is calculated from inputs, All the sensor signals are steady and smooth both in the logs and on the scope. I did a lot of research on this issue with Robert and in the ECU forums and other people had the same issue, several open-ended posts about airflow smoothing... The only people who had success fixing it far enough to stop posting used airflow smoothing. I'm not sure an AEM sensor would fix this? But someday when I go that route and make provisions for a different style of sensor, I'll turn airflow smoothing off and see what happens? In the meantime, I wish I had a better speed sensor input, but I've got a 1990 transmission. So naturally I'm left with the 30 year old Hyundai gauge cluster doing all the speed signal work. That's the only sensor or part I haven't replaced?

@@Jafromobile I'm assuming it's a 90 DSM ecu in the Hyundai? Perhaps it's time it gets a hand me down 2g ECU from the GSX. I can't say I've ever see an issue like this with the 2g ecu and it would also use the 2g speed sensor natively.

It's not an impossibility... I considered putting it in one of my Galants because I thought it would be pretty fancy? My 2g ECU needs a V3 upgrade, though. Hmmmmm...... Hhmmmmmmmmmmm....

I know. And look at the knock on those logs. The knock is real, which we always thought was a lie because it loves doing it where it shouldn't... and that indicates a problem that I've apparently built into it. So I have to run it a bit fat like that to keep it from pulling all my timing out. I have a plan for that one day, but this is how I have to do it for now.

Correct. It is not running rich, but only because it pulled the fuel out. The condition of it wanting more fuel than it's delivering in order to run correctly means the tune is rich. There are several places where it is pulling 20+%. The Wideband says I'm stoich, but it's having to pull the fuel to get there. I'd qualify that as rich all day long. I'm glad the fuel is not getting there, but I'd prefer my fuel ±0 instead of 20 points either way. That's when I'm confident with the tune. But truth be told, my Wideband sensor meters .4 points lean. That means when it's spot on, it's actually .4 points rich. I might try some other Wideband systems and see if I can get one that's closer?

The clutch in it is an ACT Extreme 2600. I just pushed through a 2600 lol. The 6-puck uses the exact same pressure plate, so it's going to be the same as it is right now, actually. I've used the XT2600 in all of my projects so far, and yes, RCLS is real!

did you miss the front mount?? no not naturally aspirated, stock internals tho.

Nah, there's a tiny little turbo in there that I got one bay for $224 new. It's a TD05H 20g. But the engine block is a stock non-turbo galant block. Stock crank, rods, OE replacement non-turbo pistons. Fel-Pro head gasket, 1.6L Elantra DOHC head. Clutch, cams, valve springs, turbo, manifold, and o2 housing are leftover parts from my old GSX 7-bolt. They fit. Somewhere everything has broken or blown up and been put back to use. This really shouldn't work. But both the cylinder head and everything below the head gasket are all factory stock parts from normally-aspirated cars. I did put ARP mains in it on its last rebuild, but I really didn't need to at all. They were just cheaper than new factory main bolts.

@@Jafromobile I did not realise that was a non-turbo bottom end! I assume the N/t Galants used the same compression ratios as the N/T dsm 4g's or are they different?

Yes. 9:1 cr. It's a 10cc dome piston. Both the head and block have been machined so far past its service limits that I had to make them fit by opening up their fly cuts. Valve clearance was tricky on this one. The Elantra engine assembly videos are some of my best work. "DOHC valve timing" and "fighting the valve clearance" are the best parts, I think, but the whole build is here in HD.

...but it's really 9.875:1cr. I'm using a 1.6L Elantra head that's 4cc's smaller per dome. This is why it likes Ethanol so much.

On which car? 2/6ths of them do, so depending on which one, probably.

@@Jafromobile on the hyundai above the drivers side back door. Or am I seeing things 🤔

@@lostwill86 Yes. My forensic analysis reveals this car was likely under a fallen tree at one point. There was damage to the rear C-pillar, and that section of the roof that were previously "repaired" with bondo, which has since waterlogged and flaked off, revealing a bare metal spot that rusted. It was found in the junkyard this way, poorly repainted but otherwise appeared straight, and with only 53,000 miles on the clock. The whole car was picked up and set on a flatbed to be hauled away to this new life.

@@Jafromobile with all the work you've put into that chassis it's probably worth looking at repairing it properly but appropriately for what she is

:( Dang. I worked hard making it. ... and Abe said it was fine! But one thing is for sure... the clutch hates all of us!
