Tuner and builder/supplier of the turbo is now claiming that this truck has an electrical and/or fueling issue which it literally ran perfect before the new turbo on big tunes, so just looking to see...

would somebody look at this log and tell me if anything stands out that may point to my issue causing my cutout/surge that I picked up since adding a new turbo.

LOL... I love how this is still in the "Read Me/How To" section basically saying "Good luck idle tuning anything with an E40"

At the time, I did not recall getting a code before i changed out my PCM and only recently noticed that I was, however - I neglected to mention that because at the time I thought the P0128 was a...

I was looking at killing the P0116 after reading this and was wondering if I should get the p0117 as well?

Just for the record... I have a 180* stat

I want ahead and -no reported- p0128 after I read this post and researched it further only to find several had the exact same issue. Problem is, now I?m still monitoring everything and not sure if...

I will setup to monitor between the ECT source/reference pins on the ECM - as you have suggested. I would really have to record this if I want to catch it when it happens as I have yet to catch the...

Hey, I didn't realize I had so many responses, I guess I missed the notifications but non the less all good input and I will take into consideration as I continue to trouble this issue.

With all...

this is good info to have, You wouldn't by chance be able to clone BCM's as well, would you. I would like to have a spare PIM, BCM and IPC on hand since these parts are becoming scares.

I think you are right, after doing some research I found out that the AC disables if the PCM doesn't know what the ECT temperature is. I will verify all wiring. signals and sensor is in good...

good info which I hadn't found yet in hours of google searches - Thank You

So, I'll summarize my issues (that I have noticed) and try to pinpoint how each is controlled using what I think I'm...

Back story - I have been having an intermittent temp sensor signal issue that a reflash of the ECM will fix temporarily. When the signal fails, my gauge drops to cold and fans quit working. I'm not...

Well... all is well in Tulsa, OK with the new ECU. I don't really know everything that was wrong with the old ECU but this new seems to have fixed my issues above but also handles Idle Air a lot...

Thank you for the info, all good stuff. I was able to locate one with the correct service number and it will be here tomorrow. Not on 05/06 5.3 impala, envoy, trailblazer etc or their SS counterparts...

I thought that this was solved, but the issue was only delayed a couple days and it is back to as described above, only now it was warmer out and noticed that the AC dropped out and my engine fans...

"SOLVED" - So I thought

In the event that somebody may be interested in the status, the problem was solved with a "Write Entire". I hate not knowing what what the problem was but I'm going to...

Sorry about the typo in the title... It is should read (Losing Temp Gauge Signal)

So, everything had been working perfectly until I changed widebands and updated to HPT 4.2 but I'm not sure if...

Just curious if this was removed from the Coyote? I'm not seeing any option for it.

Now that you say that, some of the grime was a little stubborn for the Throttle Body Cleaner so I reached over and grabbed a can of Brake Cleaner for that stuff and did spray it directly on the TB so...

Update -
Although I'm not sure if that "catch" in my throttle body blade travel around 20% is normal I did get an opportunity to try another TB and all is well again... daisy's, unicorns and...

I?m unable to tune it out... I went as far as zeroing out the RAF table just to see how it acted and was still not able to bring idle down below 800rpms, and on top of that it was pulling 9* of...

I did consider a leak since its certainly the symptoms. I haven?t smoke tested it but I did pull the TB back off and change the gasket out. I guess I could have damaged the second gasket as well but...

Was first thing I tried and was patient for a full day while the idle raced past 2k rpms on several ocassions but hoping I was just having an abnormally bad episode of TB relearn. During that time, I...

Well crap, then I don't understand what I did when I cleaned my TB. I assumed Dynamic Airflow at first but when I monitored my "Base Running Airflow" over the weekend after I started having runaway...

I'm sure that I am overlooking the obvious but I just cant seem to process how to monitor base idle airflow w/out a MAF. Is this possible?

Hell, I may be going in the wrong direction completely...
