Have any of you had this code? From what I've found it is in the pcm. I dont think its in the tune because I have tried a few different tunes and it will go into limp mode on all of them.
It started when I put one of the old tunes back in that it used to run all of the time. Was driving normal and all of a sudden the repair stability control lights came on and then it went into limp mode. always able to shut it off and restart it and it runs fine. It is an HP Tuners unlocked pcm. Also is it possible for a bad pcm to change tune parameters at any time?
Thank you in advance!

It showed P061A. that's all it showed. It has an internal code of U1424-00, C121C-00 and U0401-00 Implausable data from ecu too

Have you tried rewriting to the ecu ? Is there any values that exceed the factory maximums?

I just did the calibration and not the full rewrite. Could that cause this?

I don't think so . I have never used "full write" and never had an issue . But I have see the write calibration not take some times ( very rare ) .
I would try reloading your tune and try it again

Ok. Thank you. The only thing is it has done the same thing with 3 different tunes.

Ohhh . That's not good . I wonder if the Pcm got corrupted . It may need to be reflashed by the dealer and you start over .

That's what I was wondering. It's a HP tuners unlocked pcm. I have the stock one but I'm not sure what will happen since it has the 2.85 upper and 1050 injectors.

You can not start the engine with 1050's and the stock ecu . you would have to put the stock injectors back in if you wanted to try the stock Pcm and no WOT .

Ok. That's what I thought. Damn. Lol. Thank you for your help. I wish hp tuners had a phone number to call to see if they can reprogram it or if I need to get a new one. Just sucks at $900 for a new one.

Open a ticket with them . They can reflash it too. It couldn't hurt to try .

Just a thought, many have had issues with the wiring to the shocks, especially rears when running smaller diameter rims...maybe jack it up and check to see they aren't nicked or damaged. Also check the Canbus junction connectors, one set under dash, one set in trunk under mat right side by rear seat back. They have the 2 wire connectors with green and white colored blocks.
