Loved this series so far. I'd absolutely love to see before and after dyno runs with and without the ITBs on the Ford ECU. Would be interesting to see what the plots look like.
I’d like to get some dyno runs done but it’s money and more importantly time to get them, difficult to carve out time with a full time job and kids etc…
Hi, loved this project! Here is an idea for your vaccum manifold: remove the injectors from itb and replace by dummies, and use the fuel rail as vaccum port.
@@MakingforMotorsport haha, glad you appreciate the idea. May not work if you're planning big turbo and twin injector set up though. And we know you're a naughty boy ☺️ (Ps, you're the reason I have a speeduino on my desktop, thanks for being an inspiration)
That will cause a similar problem to his oversize manifold. You need the volume to be small to be responsive. An undersized fuel rail could work. Location sounds like a good idea.
ive been shaking my head positively in every situation you came across. mate, im a car mechanic even for me your videos about itb's are educational ! ive been searching videos like this because im on the same mod myself 4age 16v with itb's with stock ecu .+ super afc apexi . no one ever made it run properly with stock ecu or even that added apexi fuel controller. its kind of a challenge for me ! thats why im pressing my self to finish it and completely fool the ecu like you did . relocated the tps so i can use the 16v one , relocated the iat sensor on the t3 adapter between butterfly no4 and cylinder head and using the original TVIS system so it has good speed density on idle .small vacuum manifold for map and fpr and servo booster . if i manage to make -55 -60 kpa on idle ( original value ) i think i can make the apexi's life easier !!! lol. fingers crossed!! thanks for sharing knowledge!!!!! keep it up!!!
Love the honestly in your videos. The fact you're not screaming and saying the car is completely different is refreshing. This is a really cool project and I look forward to seeing what you do next!
LOVING THIS SERIES!! This stuff is right up my alley with things I've been thinking about doing. I'm so glad I found this channel. I'm really looking forward to all the speeduino stuff. That thing has intrigued me for so long now. I've got a couple junk cars standing around at home. A subaru legacy bg with the EJ20 in it would be a nice candidate to see if I can get it running on a speeduino. ITBs on a boxer anyone? 😄
ITBs on those Subie engines sound amazing. I wish I could’ve done it on my Subaru but it would’ve been too involved of a process. I think my 1JZ-GE will be a much better candidate for ITBs.
Thank you for this! Finally someone showing the magic of making a map sensor block for ITB’s on a stock ECU, would love to see a budget exhaust manifold and De-cat before the mappable ecu
I’ve gotta be honest, I’m rather impressed with what you have managed to do with the little fizzbomb mate. It sounds like a MK2 Escort with twin 40 webbers on it so that’s a definite win in my opinion.
Before you go full speeduino it would be really interesting if you could plug it in with only the wideband, and log what the original ecu is doing, how lean or rich its running as it is. It sounds so good, proper race car feel, if you don't look at the speedo of course 😂
This is really sweet! I love the low budget, yet high level of design. Proves that you don’t need big budget to improve your car. I wish I had access to 3D printing when I was a teenager!
Hi David! First of all, your videos are a huge inspiration for me, thank you for all of your work you share with us! I did built mine ITB setup for a ford sierra 2.0 dohc with ECC - IV ecu It is basically the same as yours stock setup - MAP and O2 sensor. Unfortunately, I was not as successful as you were. The best vacuum I am able to pull is around 16 in Hg or 54 psi and the ECU is having a hardtime thinking that the engine is under a load all the time. The afr is pig rich at idle and partial throttle as well. If I was able to pull a higher vacuum, it 'd be golden and really usable, no problems at all. I am going to try a vacuum block setup with checkvalves - Just out of curiosity, if it helps to pull a higher vacuum. To whoever who would like to run itbs with stock ecu and map - dont do it. Standard ecu will not tolerate ITBs, at least from my experience. Looking forward to more experiments/ITB setups and builds!
Hey, I've got a project on hand - a 20v 5cyl swapped lancia delta HPE '97. Do you think I should go for the speeduino and do lost spark 5 cylinder or buy a 6-channel sparkefi standalone and normal sequential ignition / injection? I'm torn because I want to do it right and not spend a lot of cash (expenses are basically a few times more cause poland is a 2nd world country) you're the one who basically got me into this ecu world.
It’s difficult. The 6-channel would be more elegant but people have run 5-pots with a 4 channel Speedy. I’d say get on the forums and really understand what a 4-channel speedy needs…. I am always a fan of just getting stuff going to enjoy it, hard to enjoy it when it’s not running. Cheapest, fastest, worry about perfection later. 👍. (But that’s just me - if you are a perfectionist then maybe not)
GM LS coil packs mounted on a plate somewhere near the spark plug holes (there’s a reason everyone and their dog uses them), and some little HT leads. Run an ECU that can handle 5 coils packs.
Incredible!😂 sounds amazing!😆 Great work, even more keen to do this to my daihatsu. Great editing too, you put the video together really well, finally i can watch someone who doesn’t just walk around talking into a camera about what they just had to eat instead of showing us how they actually did things to their car!🤦♂️
Amazing work, I foresee hours on marketplace looking for cheap cars with oem map sensors lol. I would love to do this for myself. You can boost Idle Kpa and stabilize the kpa more if you use one way vacuum check valves on 3 of the 4 runners vacuum lines leading to the map sensor.
That's exactly the sort of setup I've been planning on using for my DIY itb's on my integra. small reservoir, some check valves, and bam, smoothed map signal
@@kasuraga Did it for my ITB miata and it worked really well. I have a aftermarket ECU so I was able to monitor / record my KPA readings and was able to configure my ITB KPA behavior close to stock.
Might have been pointed out already, but both STFT and LTFT are determined by the pre cat\upstream sensor. Post cat is used for cat monitoring only. Car sounds great tho.
When I make parts like the MAP sensor adapter, I usually print NPT pipe threads so I can use a threaded brass barb. 3d printed barbs like that always seem to break off.
@@MakingforMotorsport you dont need to put it back standard for the mot. They only test for exhaust I think it still probably be within MOT emissions limits
Great content. I'm currently building a puma autocross car and this is giving me ideas of doing my own conversion. After ecu and mapping I'd be really keen to see hp and torque increase.
first vid of your channel I watched - subscribed! Ps I owned and loved a 1.7 Puma swiss cheese edition a few years ago and am a HUGE fan of that platform.
Thank you for the series! Already used your Mini videos to fit R6 Carbs on my 1.3 Micra. So next step it's fit ITB's to tunee it properly! Really really good material🙌🏼 You can see it running on my channel
Hi there, I did many cuts of this and talked about catalyst efficiency and a host of other stuff, but I had to boil it down to the essence and just explain it’s tiles in helping this system work. But OEM units really aren’t my bag at all… far prefer a mappable unit!
Yeah, I have got that but wrong, I did have a much longer section which included catalyst efficiency etc etc but had to cut it down, it just look too long! Guess I cut the wrong bits 🤷♂️
Amazing Sound. I thought it was a 8v Zetec Rocam 1.6l engine, but I realized it was revving too high with a stock ECU, and when I saw the engine I realized that the RoCam engine is mostly seen in Brazil. Nice build tho!
Going wideband with the Speeduino should also really help in eeking out every last BHP possible :) I love content like this as I'd love to tinker with this side of engine tuning if I had more time and money.
Brrrraaaaapppp. The noise is every bit as glorious as expected That works shockingly well. Thank you emissions tech for doing something useful for once.
@@MakingforMotorsport also, more details on the printer enclosure please! Keen to hear how the printer is going/any setup changes you've made. I've got an enclosure mostly done to try and print standard nylon (it's cheap), but I'm yet to give it a go yet. Need a dry box first
wow... new Subscriber, I have been thinking of doing something on my little EP1, only problem is the Inlet manifold is in a lot harder place in the engine bay...
Not quite. The O2 sensor after the cat is used to determine if the cat is working. If the ECU sees anything other than lean exhaust via the rear O2 sensor, that's a problem. If the cat is working, any surplus fuel gets consumed and the only things that should be hitting the rear O2 sensor are water, CO2 and nitrogen oxides. All of the fuel should be gone, unless the cat is not working, in which case you throw an emissions code. When adjusting the air/fuel mixture, the ECUs will only vary the mixture by +/-X% (like 25%) in a particular running session, this is the short term trim. So you have a base number and a short term adjustment. A longer term adjustment is calculated and stored for the next running session so that the mixture doesn't bounce off of the limits of the short term trim. This is the long term trim. It's like recentering the mixtures to correct for variations in injectors and sensors. You shouldn't be bouncing off of the short term trim limits all of the time, and if you bounce off of the long term trim limits you've got injector problems or air leaks.
Yeah. The first version of this video talking about conditioning the cat and cat efficiency checking and non resetting LTFT and lots of other things but I paired it back to stay on course… but I did get the tasks of the sensors wrong 🤦♂️.
Oh absolutely, off load it was razor sharp and on the road it was noticeably better, but just not having the power means it’s not a massive difference.
next episode, home-made big cams... but in all seriousness, I'd love to see the whole works on this car. I'd like to think you could get at least 120 hp out of her with cams, exhaust, port and polish and a map.
What ITB's would you say is a good way to go for a 1977 Chevrolet/Vauxhall/Opel 2.0L CIH motor, I will also going to be running Speeduino. Many thanks for the great content. Warm regards from Port Elizabeth, South Africa.
I don't run ICV on my peugeot xu10j4rs, we couldn't figure out why ecu wanted the valve to bo fully opened all the time so I just blocked it. have been running this setup for 3 years now almost daily (apart when there is a salt on the roads) and in cold weather I just need to hold throttle a little bit open for about 30-50 seconds and it idles fine :)
I really enjoyed this siesta series and you have a new follower. Would you ever consider making the 3d prints for this experiemtn available, maybe to patreon subscribers? I'd love to try out this on my 1.4 puma.
You two look like off brand colin furze and alex from car throttle :D I'm 3D printing mostly from ABS and brush on acetone C6000 on the prints so they get smoother and sealed better, it is also good for sticking it together
Yeah, I had pieces in there about the cat efficiency and even more but it turned into half the video. I re-did that whole section and basically chopped it in half because mainly I think people are just in it for the Braaarps! 😂
@@MakingforMotorsport we are. But that doesnt mean the tech bits doesnt matter as well 😁👌 i am watching every single one of your videos with great joy.
This is so cool! I haven’t seen anyone in Germany running itbs on a stock ecu. I would love to see a sharp cam shaft, mechanical lifters, some funnels to influence the behavior of the engine and remove the rpm limiter. I think I’ve seen an excel table in a German forum to calculate the correct intake length
Hey! Nice project! My Fiat 16V has the same MAP Sensor. Maybe you can upload your STL for my 3D Printer. Would be nice for my ITB project. Thanks! and if not Thanks too! Love your Videos!
Hey. Good job 😁 love your videos. I don't know if someone already asked it of not i have a good question for you. How i have to calculate the diameter/cyl for my stock injectors bc i don't want to use the car with lean mixture or rich mixture. 1.4L aex vw engine Thank you for the answer.
Yeah, the emissions you could pass I reckon… I know certain areas (California) have the ECU do checks on the cat efficiency, speeduino can’t do those so it would fail those areas…
First, congrats about what u done, but what you did about the idle control valve? I was thinking about do the same as u done with the inlet pressure sensor , I have a Peugeot 306 GTI and thinking about to do this
I got a set of ITBs but not fitted yet as fighting with trying to get the (1.7 Puma) engine running on a Speeduino. Any specific reason why you used a combined air temp/MAP sensor for the inlet air temp instead of using the standard/OEM sensor? I guess the other MAP sensor replaces the MAF sensor? Great work, can't wait until the next video!
That is the standard sensor. I think the ecu differs a fair amount to the 1.7, hopefully I may find out as I have one on the garage floor to go in the mini! 👍
Hmmm… they do airline versions of that (had some on my paintball gun 😂) but it’s probably a bit overkill for this when just a tight fit will do for vacuum….
@@MakingforMotorsport I figure it would be easier for 3d printed parts.. those small hose barbs are not sturdy enough, a threaded hole is much easier to print. Anyhoo, great work so far!
post cat 02 sensor does not control long term fuel trims. it cant, because the cat has altered the AFR. Long term fuel trim is the average of the short term trims.
Yeah, got that bit wrong. I did have this section completely different and talked about catalyst efficiency and the effect it has and the need to keep it conditioned, but it was half the video, so I dumbed it down a fair amount…difficult to pitch the tech stuff…
You want 45s or 48s for 250+…. And I want 250bhp from a k24, that’d make my beemer fly… As for the channels, I just wanted to keep it simple to start with, had I kept the car I might get more complex and neater with the packaging
Awesome stuff, I tried a similar thing on my car recently after seeing the success you had, but had issues with cf nylon deforming at the bolts after just idling the engine, even though it advertises 150C continuous use temps. I even had metal inserts, but after running the bolts would be loose and would leak coolant and vacuum. Do you have any recommendations on what brand of cf nylon to use?
