ECMlink 30psi 16g 3rd gear WOT Log

[habitatguy187]

I do a WOT pull past peak VE, which is 5500-6000rpm. I'll adjust the base fuel pressure on the fpr until AFRatioest=WB, AND BoostEST=map sensor, AND the value used on the mafcomp is zero OR the value use on the SD table is 100, all at this peak VE. When those 3 stars align between 5500-6000, it's done.

I see where you're going with this and it's finally making sense. To clarify, the stock sd table has 99 VE at 4500rpms but you're saying I want peak VE at 5500-6k correct? I was able to get a 3rd gear log today. It has some knock in it but, ignoring that, if I'm understanding things rightly, I should raise fuel pressure a little. Is that right? I'm not sure cause my wbfactor hits 0% right at 5500rpms but my boost est is off by 2psi.

I already started the cruise tuning in the sd table but the wot cells haven't been touched yet.

That's a bingo. I'd give the afpr a half to 3/4 turn clockwise and do another pull.

So far, I've always adjusted fuel pressure with the car off by turning the pump on in link. Per your advice, I slowly turned the fuel pressure up from 43.5psi to 51 (making a pull after each adjustment), and it didn't change my wideband at wot AT ALL ugh .

Went to adjust it with the car running for once and the gauge on the afpr didn't move at all when I pulled the vac line from it, so something's up. There is no liquid in the gauge. I've also noticed that the car used to hold fuel pressure after shutoff (20-25ish psi) but now it drops down to zero. Guess I'll take the afpr apart soon and have a look at it
