Hello again all,

This thread is in regards to some timing CF issues i'm experiencing.

I'm seeing timing corrections at IDLE, DECEL, and THROTTLE TIP-IN which of then continue on to WOT but start going down as the revs climb.

This was not the case when the MAF was underscaled but i do believe the timing map was much different then as well. I know because of this issue i see about 5deg less timing up top which is VERY noticeable. The timing map below about 80% load is pretty much stock or a little less for the sake of keeping that V8 down low drivability.

My tuner and I do not have an A2L specific to this ECU nor have found one so the variable locations for the one we do have do not apply. My ECU is as follows:

HWNumber           = "0261208443"
SWNumber           = "1037374043"
PartNumber         = "8E0910560K"
SWVersion          = "0010"
EngineId           = "4.2L V8/5V"

Locating necessary variables hasn't been successful either. (zwist, zwsol, zwbas for example)

I've attached a log of course for review. I forsee needing to have this ECU decompiled in the future Undecided

If you expect to add FI to a NA ECU, you had better have the ability to trace ANY variable at will..
