Restart drops AFRs a point
 

So, the car hasn't been behaving lately. I start my car (sat for ~2-1/2 hours), and drive it for 5 minutes or so. Second gear is steady over 13, upwards of 13.4 in places. Does this a few times, occurs in multiple gears. Accelerate in the same fashion to a stop light, 13.4. Restart car. Nothing above 12.5. I've been in the basement of the engineering building for far too long today and bluetooth wasn't cooperating, so I do not have any logs. I'll upload the msq though.

Car is a 2000, so returnless fuel system.
AEM EUGO
MS3-X
EGO, MAT correction, et al. are disabled (I'm 99% sure, might have re-enabled some but I don't believe so)

ASE.

lol at tuning for 13-13.5:1 cruise.

Err, I don't see anywhere I'm targeting for 13-13.5:1 at cruise?

ASE, After Start Enrichment.

This is your ASE Taper table.

Taper sooner than 230*F

I have mine set to taper around 180*F

My guess is your car is in ASE the whole time with your good afrs. Then when you get higher then 230* your afrs are lean because ase tapers off. Or my logic could be backwards. You need to lower ase taper then retune. Probably something else in the mix too, I didn't look to hard at your tune as I'm at work.

But you didn't say where you were getting the 13. I think it is WOT.

Mazduh: ASE is set at the crank temp and then is timed out (by tenths of seconds or by cycles as set elsewhere). The X-axis is the temp at start only. WUE works like you are thinking.

Sorry, yeah, all this is WOT. And it is targetting 12.5, and yeilding 13.4 in this situation. I'll look into the ASE stuff though.

As yes, sorry for the confusion.
