Awesome feedback. Thanks. I'll let you know how it goes later this week.

Log posted above. Any thoughts?

Sorry for the delay in getting the log. Weather and holidays got in the way. Log file attached.

Starts with a cold start. You'll notice closed loop doesn't kick in until ECT hits 130. Idles a...

I'll get a fresh one today and post.

Built a sweet 2002 Firebird with PRC heads, FAST intake and fairly strong cam. Dyno tuning went well and this baby cranks out about 525 HP. Driveability in closed loop was pretty decent even though...

Ah, OK. Thanks, Jaime.

Bill, we've updated to the latest Suite version (2.24.887) and still get the 1F80 error.

Bill, is this available yet?

Took it to another dealership and as we all expected, flashed with no problem. Fortunately first dealership agreed to refund but a huge waste of time.

New tune built and loaded. All problem codes...

Yeah, the young technician didn't inspire a lot of confidence when he insisted that he had his 2006 Mustang "chipped". Said he watched them open it up and put the chip in. I need to meet these...

Thanks, planethax. Read the PCM and Calibration Details show "ECM Unlocked"

Also attached file in case there is something else to check.

Bill, took it to the dealer for reflash and the kid tells me the computer either has a chip in it or is locked and it won't take the flash. I reminded him that the OBD II computers don't have a port...

Bill, similar issue. Tuned an '01 camaro but kept throwing an 1153 code. Tried adjusting delay to no avail. Was going to try setting the code to 3 so I could get it through emissions but could not...

Crap! I was afraid of that. Good thing is it's stock with CAI & headers so not much changed.

Thanks. Have a stock file out of the library here. I'll give it a try.

Having the same problem on an '01 Camaro with LTH. How does one "3 the codes" for these. They don't come up on the VCM Editor list. Highest number on the DTC list in Eng Diag is P0410.

Well you're not alone in this problem, bluegoat. Ours is doing it as well, and in fact it does it twice in a row before it finally steadies up at WOT. Check this out. Waiting to hear back from tranny...

Actually Chris, your Holden boys build a pretty nice car. For a four door sedan, this one's pretty sweet.

Nope. Nice smooth pull all the way. We have a Mustang that needs a baseline. We're going to put it on there first and see what the readings look like to verify the dyno setup.

One of the other...

Thought it might be a screwy WB reading as well but it did it consistently at the same spot on two pulls. A bad WB would most likely be erratic.

Will try to 'gently' nudge it as you suggest Chris...

Attached are the dyno graph showing the AFR bump and the Scanner file. Just to let you know, it wasn't a one time fluke. This was the second of two pulls and it repeated on both.

By the way, thanks for the link. Confirmed we have the correct calibration. Other website (tunfiledepot) apparently had bogus data.

Thanks for replying, Chris.

Started with the car's previous tune (not ours), returned all ECM parameters to stock except MAF curve, injector profile and spark tables and then started dialing back...

Have a 2009 Pontiac G8 GT Automatic. Built motor, Procharger (we didn't build it). Doing some weird things on dyno. Began looking at all your previous posts and read about IFR limitation of 63.5 on...
