I used to have an M62 charged Saturn SC2 (bet you could guess that lol) It was non-intercooled, run ~13psi when it was cold. We saw IATs ~200-220F. Timing was in the single digits. That engine survived, I dunno 5-7k before the car was totaled. I never tore the motor down, but it did get sold off and now makes in the 400s on a turbo setup.
Well after a few weeks still haven’t got this thing dialed in at all. I fought to get injector info for the first two weeks... after many attempts I believe I managed to get somewhere with it. My iac was in the 150+ range so I found out my scaling was wrong for 90mm TB adjusted that... made a huge difference- I’m now within 46-55 range warm idle
ive tried doing the idle tutorial for it, which I can get it to idle after holding above 1400 rpms for about 20seconds for the first start up if not it falls on its face dead
nelson did my last tune it did same thing- I got my jumping idle to go away too- if I bump gas it surges and sometimes catches... if not restart it jumps to 1000 rpms and comes right back to idle. However if fans are on or ac it does surge... I’m stumped and ready to give up-
i contacted Nelson back on the 16th of July no contact since-
So I’m running SD 2 bar this is my last log I did I noticed
my maf is reading 14.6 grams at idle, my final airflow sum shows 16.3 grams (still failed but plugged in maf)
And my park airflow is 17.3 grams
**** is all over the board- afr is 14.4-14.7 at idle if I bump gas it drops to 13.0 sometimes lower to 12.6

I got the PN off these injectors and am having no luck finding out which ones they are...it says this
C1A and below that 2054B
WHAT ARE THESE? Lol
Also when I do calc.maft process for ve table it says im lean in areas via wideband but still pulls more air out of ve in those areas im lean which in turn is making it leaner..... so my data I have is junk- back to the board of finding info on injectors
Dug through forums from back in 2008 from when my buddy upgraded these injectors- they are multec 2 truck injectors made by Delphi - now I need to find the data.. getting somewhere
Well I got a offer for the supercharger setup, so I took it off the truck lastnight to make it N/A again. I flashed in my latest tune from being all motor with 42lb injectors. Started right up perfect for 10 seconds then shut off like I turned the key- restarted and it was running super rich- 10.6 afr - 40-45 kpa on map sensor- KOEO it was 98kpa one code that came up was po106
Do I need to remove the custom cos3 ? Or should I be fine just flashing my last 02 os in? Running 1 bar map again
This thing has been giveing me headaches over and over-
