Love the channel man! Been following you guys for the last couple of years! I had a question, could you give me any tips with dialing the ID1700cc injectors on my evo x? I’ve been stumped trying to smooth out these injectors on 91 pump gas at idle. it’s been near impossible to keep them from lightly stumbling. I have them close to smooth and I’m realizing I need to smooth out the Low Pulse Width adder. I understand tuning is based on empirical data rather than plugging in an answer from a formula, but is there any tip you can give me to dial these injectors well or if there’s any other maps I should adjust rather than the fuel and timing maps that can help stabilize idle. I know tuning open loop and tuning on speed density is another option but I want to see if I can keep these injectors stable in closed loop and on maf before I jump into that decision. Any answer would be greatly appreciated! I’ll donate some money too!! Thank you!
I don't understand what you mean by "smoothing out" the injectors. I do not teach people how to tune. There are plenty of online courses for that. But Evo x platform like most platforms, to tune after market injectors or intake etc you have to follow the fuel trims. That will tell you everything. Using that u scale ur MAF and map , or injector size and dead time or all of them. Again I do not teach people how to tune. You should pay for a tuning course.
@@bdalchemist I’ve been trying to follow the trims but for some reason, even if I get latency,scaling and even adjusting the VE table to get STFT and LTFT down to 2-3% combined, it seems to still have this “falling off a cliff” reaction. When the engine is warm, A/F ratio fluctuates between 14:3-15:4, which is great! But then it randomly riches up to 12:5-13:5 then leans up to 17-18. Seconds later, it stabilizes back to 14:3-15:4. I guess it’s just the mechanics of this injector. It sucks but I understand 1700cc or any big injectors have larger minimum injection so it seems near impossible to tune them close to stock on pump gas. I’ve done boost leak tests, smoke tests for vacuum leaks as well as a leak down test to check the health of the engine. I’ve also changed the fuel pump, checked for any wiring issues and everything is perfectly fine. I’ll keep looking around to see if anyone has ran into this issue with a solution. Thank you for your time!
Ls and lt a structurally different but alot in the same and they have had LT motors before it's not a conversion from LS the LT was first introduced in 1970 as a option for the corvette. The newer LT is and advancement over the recent LS but LT itself has been around a min.
Just a bit curious. Say for an instance you have an inline oem fuel pump feeding the surge tank and then a Bosch 44 external pump in a series configuration to the fuel rail. Since the external pump will be noisy. Will I be able to just switch the external pump off (when i dont need it) and let the inline pump do it job?
"inline" is external to any container and independent in the fuel line. I wouldn't recommend it for what he asking. I also don't recommend any inline configuration unless u have a gravity feed fuel cell.
you said it had a 7670 before ? So are there any actual comparisons before and after ? Does the smaller unit really spool and perform much better on the low end ?
Nice and informative video. I want 750whp. Which is better, 6466 or gt42R? And about how much hp can the 3582 push with a fully built 2.3 motor on 36psi?
@@bdalchemist okay thanks. However I’m looking at 2 built evos for sale, one with 6466 and the other with gt42r, so those are the only 2 choices I’m limited to.
I think I mentioned in the vid I am currently doing engine builds, parts sales and e-tuning and street tuning until June or end of May. That is when the new shop will open.
cool video! I'm curious what pullies you were running. my car is a 416 ls3 tr6060 car and i made 774/690 with an 8.1 lower and 3.8 upper on the v3 ti head.
I only have a 3.4 upper. All else is stock. Making like 12psi should be 13-14. I also revd to stock redline. Not that much timing either up top. I fee this will make 800+ if I really pushed it.
@bdalchemist I was 12 lbs of boost also. We should have had roughly the same blower speed if you had a 3.4 upper and stock bottom. So it mostly adds up. I was on e85 and had 23 degrees of timing though. I could have pushed mine a little harder and got over 800 I assume also. I'm on a ysi now this year. I havent got to the yno yet but I assume I'm over 1k tire
