860 Performance

I posted this on the efilive forum, but that forum is dead in comparison to tech, so here goes.

I have the iat relay/resistor trick done to try to pull timing when spraying, and by looking at the logs, my iat jumps to 178deg as soon as the noids open, but I get no timing retard??? My timing stays right where the high octance table says, and I can't figure out why?????

Here is the log, and related screen shots from my tune.
Does anyone have any ideas?
BTW, this is an 05 GTO
TIA,

If you could, post up your tune and your log file with the respective frames. Maybe there is a glitch in the software?!

I think there is a glitch, I'll post it up tonight. (its on my lap-top at home)

The scan snapshot you posted only showed IAT at 111*. Your tune shows no timing adjustment until 140*. Could you look for a WOT run, or one where your IAT's fall into the range of the table?

The 111 is just where the "line was" which wasn't even on the screen when I hit "print screen", but you can see where the IAT bumps up to 178deg, and the timing dosen't move at all.

Yeah, it also went pig rich at the same time according to your LM1. It looks like you did everything right though.

Yup, because the MAF got flogged by a healty dose of N20.
I'm working on leaning that out.

What value (Ohm and power) resistor did you use with the relay mod?

Its 330ohms.

Check the multipliers that are tied to IAT Spark reduction. There should be one based on (A) RPM and another based on (B) ECT. I believe the way it works is:

Commanded Timing + (Multiplier A x Multiplier B x Spark IAT table) = Delivered timing

So, if any of those multipliers are 0, then no change will be made to delivered timing.
