help me decipher my tune
Hey guys I posted this in general forum but it was suggested I post it over here so some of you tuning gurus could help me out. Ok guys, ive been having an issue for the last couple weeks where my car idles and cruises rich as hell. Idle 11.5 - 12. Everything has been done and checked. This started after doing headgasket, arp headstuds, gsc s2 cams, gsc springs/retainers. My tuner says only way he could lean it out was scaling injectors which are stock. Car is 04 evo 8, evo 9 turbo, gsc s2 cams with springs/retainers, speed density, and bolts ons. I'm having a member from the forums check the tune but was wondering if you tuning gurus could take a look. Maybe something will catch your eye that would explain this situation. Keep in mind car had a cylinder with low compression on this tune so now that its fixed this may have affected it. Fuel trims on evoscan are not reading. I installed a denso o2 sensor from auto parts but nothing. Ive spoke to some guys that said it has to be factory o2 sensor because others don't work as well. Would really rather not spend $350 on that right now but if I have to I have to. Let me know what you think guys.

You could try scaling injectors from 513 to 543
but took off about 7% from idle in your ve table hope it works but you should prob pay your tuner the 350.00

I figured out it was the ve tables and o2 sensor. I think I'm missing some stuff on that rom. Guys what is the difference between sd 1.0 and 2.0? Ive been reading a lot on 2.0 and the 3d tables. Is it better? Do any of you guys have experience with it? Is it worth switching? Also, I thought scaling stock injectors was a big no no?
