Default help, weird cold issues

this just started happening one morning, almost feels like its misfiring and going extremely rich, but MLV still shows it as correct advance

I'm including a very short log where it transitions, only thing i can see is the CLT goes past 170 degrees and the msq i had

I thought it might be corrupted firmware or an MSQ, every now and then i get a cannot connect to page 12 and/or 13

ive even reloaded the hi-res firmware, started from base MSPNP msq, and still nothing

Hopefully someone here can see what im missing

extremely rich...correct advance...WHAT?

I know with the cranking pulsewidths and warmup enrichments for the other PNP models DIY never got the low temp ones buttoned down.

just looked at the log. cold start? your IATs are 143-144. What's with that?

did you set your timing?

those seem like some pretty high values at idle in your VE table.

not sure what WBO2 you run but if it's the AEM UEGO you are running very rich at idle.

ive wondered about the iat temps too, im using a autozone, P# su107, and make sure im using the no afm in MT, im not sure if that could be a part that corrupted, when i first start the car both CLT and IAT temps are identical

default LC1 for wideband

first half of the log is when it has the bad idle, i normally idle around 13 or so when its warmed up

yeah ive set the timing a few times now, its dead set at 10

you know you don't have to move the CAS to change timing with an MS, right?

i have no idea what autozone, P# su107 is exactly and how it compares to the GM IAT sensor. Just because the temps appear to match at the low end doesn't mean the settings are correct. Test that sensor in some known temperature water.

Yes, i know about the cas, i just wanted to rule it out, the su107 is the autozone part number for the GM iat sensor

As i drove to work this morning the temp is much lower, i did not even get close to 140, even in boost. I'm not sure why it was that high on the log.
