If anyone run into this on a 2006 TBSS the solution appears to be smoothing up the timing tables. This is from a conversation with another 2006 TBSS owner who had this issue as well.

Was over 1 year ago. Added logs to show the issue.
It is next to impossible to monitor/log my 2008 LMM Duramax diesel. I want intake air temp and ECT. In the standard Imperial config both values read -40. If I move the location of the monitored...
Crashinaz pointed this out to 'us'. He deserves credit for it, not me.
Post up a new tune already! :usa:
14.6 @ 95 near stock tune. Ran same night. I have not run a stock tune on the track.
The TCC clutch stays locked up so the engine doesn’t slip the converter. Better MPG really and nice sound of a heaver engine load at lower RPM.
Log your fan commanded % and see what is is running at when the AC warms up. Then give it more fan in the AC fan tables. Shift the values over to the left by 1 column and matching the top value in...
Updated tune.
I used crashinaz's timing and PE table settings with permission to release.
This dropped me to 14.1 and up to 98.7MPH in the 1/4 with 2 degrees of KR max.
I have changed the fan...
Things work backwards here sometimes. Try both ways and find that the ECM doesn't listen anyway. As some Corvette owners have found with AC items. There are also some tables 'missing' for AC and...
I am guessing that the Torque Management is doing it. Some of the values just jump out as excessive to me. ECT should kick it out alone without changing the other values.
You could try setting...
You do not need the Beta HP Tuners for this tune. This tune is biased off of the older tune BBA had:
BBA 4-06-08.hpt
First off why the older tune? It runs better for me then the newer tune (Pre...
Pull the battery for a min to let the HVAC computer reset itself.
Where can I change this "delay" for the fan to respond? I have read about this delay affecting electric fan turn on as well. I think this is a feature request of HPTuners. I understand other people...
I want to know if anyone has ideas of what causes this on mine and a few other 2007+ TrailBlazer SS and not other 2007's. If I let off the brakes when the engine speed hangs up my TBSS will...
I am seeing a higher load on the engine via higher MAP readings with the changed tune. (Higher MAP = higher engine load. Otherwise the engine would simply speed up and bring the MAP reading back...
There is your answer. You see where is goes into DOD - high MAP reading and right back out of DOD mode.
:crazy:
Really pull the wire off the compressor clutch (or remove the compressor belt if possible) and 'flat line' the AC fan tables. Flat line the AC fan tables for tuning no matter the choice you make. I...
That surge is very clear. Looks like the ETC throttle is being snapped open 5%. Now to find out why.
Use your status bit display to log the AC clutch. Perhaps this is loading the engine. It...
Is it just me or is your fan % going crazy? I assume you have your wide band hooked up to the AC pressure? If so I would flat line the AC fan table just in case the fan is throwing an electrical load...
Look at your 2nd log for the ms time on the injectors and then the O2 reading. Looks like the computer is cutting fuel way down then the RPMs drop and a lean reading shows up. (So computer commands...
Yes.

Take this from Arizona temps that hit 121 degrees F and my IAT's stock have been 161.
Sorry to bust your bubble, but loose the K&N underhood hot air intake unless you get the poor thing some true...
Nail any loose items down before testing this tune or they WILL hit the back tailgate! :burnout:
