KA24DET Stalling on deceleration

Post by hatch4life » Thu Dec 07, 2017 11:42 am

What's going on guys, I'm having stalling issues under deceleration, especially after rev past 2500-3000 rpm, doesn't matter if in gear or neutral, once you get off the throttle it gets super lean or super rich and dies

Tuner blamed it on IACV, replaced it, still happens, now they don't want anything to do with it, so I'm on my own

As you can see in the log from bin file, as the rpm goes down, the TP load, load index, and injection time go through the roof?

Little background:
92 KA24DET, manual swapped several years before build (never had problems with stalling), 9:1 compression, 750cc injectors, Z32 Maf, T3/T4 .57, stock cams, 15psi boost

Any help is greatly appreciated

Probably MAF reversion related. No log file here? Please attached

Also look at this document:
