I have those 50 pound injectors. I have adjusted the flow rate, is there anything else that you changed?

 

thats all i did(sort of), how did you come up with your flow rate? i tried the calculated number but it was way lean. in order to tune for them i had to tell the computer that they were alot smaller than what they calculated out at. i just adjusted till my ltrims were a little negative. then after i was sure i had that part good i went to the PE vs RPM and worked on my WOT A/F ratio.

 

I have mine set to 5.50. I havn't adjusted for WOT yet. I am still in the middle of tuning. Did you ever figure out how to add timing. I have been messing around with the high octane table. I used the hypertech programer as a guide. I justed used thier timing and added a little of my own. I am still using the FMU from Procharger so I am really rich up top. I am going to keep it that way till I can get it on the dyno.

 

Get rid of the Fmu unit
I got rid of mine when tuning in my larger injectors one less variable to the whole system
really really don't need it to screw things up
I figure I'm tuning with a computer that ati thing isn't an axact science

 

Yeah I know but I had taken my truck to the dyno after I got it running and they didn't know how to use ls1edit to tune in my injectors. At the time I did not know how to do it either. They used a sniffer to determine my air/fuel ratio, and said I was running real lean. To solve the problem we put the FMU back on, to make sure my engine would not explode. I plan on getting it back on the dyno and getting it tuned in right with a wide band.

 

get rid of that fmu! ls1edit is soo easy to adjust with, especialy with a wideband, you can dial it in exactly where you want it. it is important to adjust your injector flow untill you see slightly negative ltrims before you start adjusting your WOT a/f ratio
