I have the car set for a correction factor of -7%, and it is still running rich... Verified this by the color of my oil, and by the carbon deposits on my spark-plugs.


BTW: (white_S2000@16) i've not seen a PM from you... Just wondering if ya forgot.

Update.... I have contracted Torquefreaks to tune my car next month with the AEM EMS!!!

BTW: The APEXI AFC-II is total crap! Been working with it for weeks now, and i'm seeing no improvements in engine managment whats so ever!

um, did you research all the information before you bought the 2.5?

AEM EMS is the best on the market, and its getting easier and easier to tuner...Apexi piggy back units are ok, but i wouldn't get one...whats the point...if your going to spend all that money on a 2.5 i think you should have the cash for EMS and proper tuning...thats just my 2 cents

I did the research, and built the engine back up myself once the block came in... As for the AFC-II, it what was "suggested" by Inlinepro, and being that they've done a few more engines then me (Or most of us for that matter), I'm apt to follow their advice up to the point to where I'm not seeing any results from twiddling with the AFC. I've adjusted the fuel on it as much as 10% @ idle and haven't seen any difference in my AFR or idle stability. Either i'm running so rich that a 10% decrease in fuel aint nothing (I am running 575ccl injectors after all), or simple WOT adjustments at specific fuel points aren't enough to manage this engine. From what I've seen and read about so far, the AEM EMS kit seams like my only solid option. All said and done, when the car is finished it'll be close to 3000-3500 for tuning and the AEM. (What hell what are cars and women for if they dont break us from time to time. ) At least i can console myself knowing that i'll never need another ECU or fuel control system!

BTW: My fuel consumption is so high, I filled up 5 times during my 1000 mile break in period! : Also keep in mind that the head unit as well as the intake, headers and exhaust are all custom gear.

S2000_Europe: Your pic's state that you are in Spain... If so where at? i used to live in Rota Spain about 8 years ago. (best place that i have ever lived)
