Comptech AFR's
Ok so i installed a AEM wideband guage to see if the dyno results were wrong from
https://www.s2ki.com/forums/index.ph...f=142&t=425952
That dyno sheet was 3 full turns on the fpr. so make it "safe" but i was having drivability issues.
So i turned the fpr back to the initial setting + 1/2 turn.
And now my AFR's are around 12.5 at WOT until Vtec. where it leans out A LOT.
goes to about 13.5 +......... and makybe comes down to 13.3 at redline.
Been at this setting for about a month without any problems...... But I thought it was supposed to be at 12.5 under vtec....
Any suggestions?

It's common for our cars to lean out during the vtec transition...however, I don't think richening your fuel mixture a bit could hurt by turning up the FPR.
A range of 11.x to 12.x is definitely safer than 12.x to 13.x

I know it's the best option. I'm just wondering if there's something wrong with my car.
a local guy here has a comptech with 7psi pulley. and he's around 12.5 all teh way acrross. I've seen other dyno plots with similar results....
They all had stock exhaust though.... I have t1r dual sparrow and t1r test pipe.....

Thats your lean running problem.
The Comptech FPR/ESM is not flexible enough to cope with anything other than stock engine set up.
If you not stock you need to start thinking about standalone ECU's or at least a VAFC.
