oops here's the tune.

I will have logs tomorrow when I can get back to working on car.

That I know :) He was raising it trying to see if it would make an impact and then My computer ran dead and he had to leave so those cells have to be set back to where they were. Stalling issue was...

i'll check on that thx

I just looked at what you stated. I have no idea why that is changed. It is at 4,000 in a stock tune. I'll ask tuner if he changed that. Multiple tuners have been in this ECU. One when 1st installed...

one other quick question about the TPS voltage at closed throttle. I keep reading conflicting info as to what voltage is acceptable. some say .45-.55v and others say up to .6v and others say it...

also, I have a 18lb flywheel. Could this have anything to do with it? Voltage at idle on tps is .70v. I will try to log more runs with correct parameters.

more logs

here's one. i will log more with IAC in chart

I have a weird stalling problem that I am trying to fix. My car idles fine just sitting but when I come to a light and push in the clutch to stop, the RPM's will fall and over shoot my idle (850) and...

and the answer is.......... fuel pressure dropping to 3 bar near top of rpm band. Now to find whether its the pump or lines that's the restriction.

Took all the Injectors to my buddies shop to flow test them. The Bosch 811's flowed the same as the LS3 injectors. So this confirms that the the 811's are actually 42lbers in our cars. This is what...

also, if i go with these LS3 injectors, which data should I use? Camaro or Z06? I see LS7 data converted to LS1 pcm but haven't seen Camaro data.

how much HP are you making? Definitely need to do some troubleshooting if your not maxing them out on a 418? I would think around 550rwhp for you.

Russ, when you say you have the same injectors, are you referring to LS3 injectors or the Bosch 811 white injectors that I have now?

I'm going to send these Greenies back then and just get the Spacers. That's what my gut told me to do in the 1st place.

will do, I have a fuel pressure gauge on the dash that logs data and will play it back. I do not recall it dropping below 4 bar, but there is a lot going on at WOT in 4th gear on the street :)

Ok, So my tuner is getting 99% duty cycle on my Bosch 0280155811 Injectors by 6200 rpm. 86% by 5700 rpm. We are using the tables from the ASA tune. These are the Bosch 36 lb injectors that came in...

James, didn't you get the correct values from James Short? Or were those once again 868 values?

just realized that all my data except for flow vs KPA is just the stock data for a 28lb inj. from a 2002 camaro. Tuner just modified flow table and nothing else. Nice huh. And this guy has been...

here is a copy of my tune. Also, I am confused as to how much these flow at 59psi. Is it 40 or 42? Are they 36lb at 43.5 psi or at 53 psi, which is what I thought I read the Pontiac v6 fuel pressure...

also bringing this thread back. I have Bosch # 0280155811 which are different from Bosch 0280155868 / FAST #303608. From what I can gather, the 868 was released with both EV1 and EV6 connectors. The...
