So I gapped my NGK copper 1-step colder plugs to .032" and everything seems fine when I drive, no hesitation, nothing. I get the right bank lean code (0115) everytime my car is sitting for at least 30 minutes at idle, and I just check it and reset it. Is it the plugs or maybe because I tightened my BOV for just today to not vent any air at idle? I'll loosen it back up tomorrow to the loosest setting again, but if that doesn't work, I guess a dyno and S-AFC II would be the next solution?

I dont think the plugs are going to affect that, might be the BOV, but even then that dont seem to be enough to kick it after 30mins. I would assume if it was that, then it would kick that light at 5mins

So you getting an SFC-II? I got the SFC-I and it seems fine. Only advantage is that they got 12points instead of 8 and a few other options that dont seem like it is necessary to me.

Im getting my car baselined one last time before I go back to alternative boosting from the s/c I had in there last month. Yeap, turbo is going in. Will be dynoing it with all the guys on the group dyno on Feb2nd.

I guess I want the S-AFC II just for the knock count monitor and the fact that its pretty much new with the 12 point adjustment. I'm just not looking for ward to paying $325 for one just yet and then also saving up for a few runs on the dyno. I wish I could go with you guys on the 2nd, but I have to work to that day to pay off the bills. I'll loosen the BOV up tomorrow and see I get the light again anytime tomorrow.

 

Yea try that out. Well let me know what you plan on the dyno runs for tuning. I get my car back from the tuner on the turbo on Feb 22. I was then going to do an hour session to tune it, dont know if it necessary or not since Im always gonna be changing the boost, and i dont know how much it is going to affect the SAFC tuning once it has been set to a specific psi of boost.

I think I'm going to hold off on the dyno until I get the S-AFC which isn't anytime soon, hopefully by spring, but I also don't want to drive an untuned sc max anymore. I will take it to my friend's dyno sometime next month or so. Ok, I so loosened up the BOV to my previous setting where it was at the very loosest and I haven't got the code anymore for the past 2 nights. Maybe that was it. I dont know.

 

Where is your friends dyno and how much does he charge?

Yea I was thinking that maybe with the BOV being too tight it was throwing air into the banks and causing the lean code. Which is possible on boosted cars.
