KCwagon Posted September 21, 2011 Share Posted September 21, 2011 Ya I talked to them but really wanna start tuning myself he thinks when we first tuned it the tmic was already leaking Based on your post, I would recommend against tuning the car yourself. Let us know how it all works out. Link to comment Share on other sites More sharing options...

If you have another car to drive then giddyup, but you are going to blow your engine up during your learning process. If you don't have enough money for a re-tune, you definitely don't have enough for an engine replacement. p.s - punctuation makes sentences easier to read.

Or what help please Like mentioned above get a hold of your tuner asap and do NOT do any wot until it gets sorted out. You will melt something with Afrs like that at high load. Are you sure your wideband is trustable and is calibrated correctly? Do your Afrs stay there through the rpm range or is this duringspool up? *don't go test it, just hoping you remember Durring the original pulls.* Dave Edit: wow three posts before I finished typing, if you don't want to go back to your tuner you will have a LOT of research to do before you will be able to fix your problem. Too many things it "could be" plus its running on a tuned map so it could be a tuning related problem,mechanical or both.

lilschwikes Posted September 21, 2011 Author Share Posted September 21, 2011 The a/f ratios stay there threw the whole range. And as for my wideband it's the aem wideband gauge and it's the same gauge my tuner uses to tune open source with. Link to comment Share on other sites More sharing options...
NSFW Posted September 22, 2011 Share Posted September 22, 2011 Log your wideband and the car's own "AF Sensor #1" and see if they agree. Just for idle and cruising around, at first. If they agree for that, then do some part throttle pulls, around 0psi, and see if they still agree. Then 5psi, 10psi, then WOT. Look for knock in every data log you make (more about that at the link below). If you see knock, stop. http://www.romraider.com/RomRaider/IncompleteGuideToTuning My car got about 10% leaner a few weeks ago (12:1 rather than 11:1) and at this point I think it's probably the fuel pump wimping out on me. Haven't proven it yet, but I think I've ruled everything else out. Link to comment Share on other sites More sharing options...
