I seem to have a lot of unique challenges with tuning that cant be solved but wanted to try another one. In CL MAF only mode tuning a 2008 2.2 with added supercharger. Car will never start first...
Did you ever find the issue/fix? I have the same setup and running into the same issue. In blend, MAF, or VE with a SC added to a 2.2 i get the same TM trans that drags me down to -10. I've putz'd...
Attempted to post this in the I4 section without luck, wondering if the general population can help. I am having significant timing pulled during acceleration. Spark management reduction (PID)...
Zero'd transmission torque reduction vs torque vs shift. Still pulling lots of timing as spark torque management type: TRANS
Other thing to note as im trying to analyze. Seems to consistently...
Ok, digging in a bit i see i added the the spark torque management type PID to the layout a while back. It changes from none to trans right when the hesitation happens. If i go into the torque...
The saga continues. After a year finally figured out my MAF issue. Restarted tuning from start now, idle ok, moving on to MAF only. If you see in attached scan from 2min 31 sec to 2 min 38 sec...

Well, i logged with TMA and its definitely the problem. Its a one for one offset when advance cliffs off and TMA jumps up. How the heck do i shut this off? No knock during the cells when TMA is...
Thanks. Whats the risk (other than detonation) if i just zero those 3 tables out?
For perspective. The feeling is similar to my 408 stroker and forgetting to hit the Traction Control button before a stomp to disengage TCS. These pulls studder/hesitate to the point you lunge...
Thanks for this. Maybe we dont have the same tables. Where are you finding base down to -10, TM down to -20, and REP (?) down to -15?????
Another extreme example. First blip was in neutral warming up a bit. Second blip was punching it.

Fixing things slowly. Only have driveway to tune at this point due to impassible roads. Seems to drive fine when not stomping on the throttle. If i ease into the throttle then stab it, it will...
Hi - added an M62 Supercharger to a 2.2 L61 in a cobalt. Stock the L61 does not have IAT2 temp input to the ECM, only IAT, and the stock MAP does not have a temp sensor (IAT2).
If i add a LSJ...
Been searching quite a bit. Not quite sure what to call it and its hard with all the table name differences by car/year/etc when searching.
2008 LT 2.2 engine with S/C added. When driving the...

Hi - I have kit car with a 2.2/4T45E out of a cobalt. The kit car total weight is about 1200 lbs. Stock Transmission tune. When driving it aggressively works to upshift before i hit the high RPMS...
Having trouble getting in MAF only mode. Noticed dynamic airflow is very high relative to MASS Airflow. Wondering what settings might cause the MASS Airflow to be 3X plus the values of Dynamic...
Yes, the D line to X2-42 wasnt spliced between the MAF connector and X2 so i must have connected another sensor low reference line to ground elsewhere. Snow tomorrow but this weekend should...
So no go on that route. But i said F it and decided on a "floating reference"??? ;)
Just cut the D line all together and connected it to nothing. Ran fine. Loaded MAF only tune... car runs....
workin it already. thats what i was thinking...
Already verified the ECM low reference pin is not shorted to ground.
well theres no way its all getting re-wired. I will try a couple things and see if i can get it separated. Thanks for the help TC
