You're very lean on your full throttle pulls. You need to target 12.5 AFR during WOT.
To Sirius's point, you should be more lean as you get closer to idle. Can't trust your wideband as much here...

Thanks for the input, Alvin. I'll look to keep refining the VE tables, especially in the deceleration zones. By chance, have you noticed this is true when running a MAF tune as well? Curious if the...
I've been strongly considering this. I've never done a segment swap, but it seems everyone uses the 0411 - 12212156 OS. This OS will segment swap into my 896? I just need the engine section, correct?...
Looking on input for return-to-idle issues. 6.0L/M6, 231/239 .62x lift, fast 102, 799 cnc ported heads. 896 PO1 PCM. Engine wants to die when car is rolling and I let off the throttle. In the log,...
TTT - I'm in the same boat. 896 ECM with P01, T56 swap. Would love to see some feedback on this. Issues with return to idle due to throttle cracker/follower and no rolling idle section.
Interested in this as well! Looking for these to be available soon
Gearhead,
this is supposed to be from a 2003-ish Silverado 2500
Hello all,
I'm having similar A/C control issues with my P01 ECM and trinary switch. Vehicle is 86 Camaro and old binary pressure cycling switch is removed. Compressor will engage if A/C is...
Kyotey, thanks for posting. I'm running a 6.0L with gen 3 ECU and similar mods with rolling idle issues also. My DFCO is completely disabled by my tuner, but if spark was your untimate remedy maybe...
Firing order in my tune is "shifted" compared to LS typical firing order. Is this possible/normal?
Car seems to run ok and made good power (450 WHP), less a few minor issues. ECU came with the...
Anyone tuning on the new 2.7 liter turbo Silverados? Looking at new trucks and considering the turbo. I'd be interested in general reviews of the 2.7 also. Thanks.
Thank you both for the replies. I've attempted to write calibration with the P0605 DTC disabled as stated, with no immediate avail. As this is a "permanent" code(apologies if I failed to mention...
Hello All,
New to tuning and recently did a write calibration to a copperhead ECU without first disabling P0605. What needs to be done now to turn off this CEL? Will I need to Write Entire with the...
For those that have these issues in the future, I believe I've come up with a solution;
Using the throttle cracker airflow table, I've set appropriate values for airflow just by trial and error...
Hello All,
As an update to this, I've been logging and systematically changing values in the throttle follower and throttle cracker tables, along with base idle airflow. It seems that the throttle...
I'll verify the year of Silverado I pulled the tune from. Regardless, I'm looking for feedback on my theory of delaying the throttle follower. My thought is; after the throttle blade closes, delaying...
Hello and thank you for replying to my post. I plan to try and make some changes and evaluate the results later today and tomorrow. I will try adding 20% as you stated. I'm running the GM -896 ECU. ...
Hello All,
I'm very new to the forum and tuning in general, but I'll try to be a specific as I can with my issue. The car starts/idles and makes great power throughout the power band. The only issue...
