Just ordered the OBD2 to 4pin adapter so I can play with my SeaDoos more. Quick question, will I be able to reset the dang beeping maintenance reminders? I have a 2014 and 2022.

And to make it look soooo exotic but can't back it up at all. How embarrassing.
GM is where people who aren't into cars go to work. All that heritage destroyed.

Yep, it's a Colorado/Canyon truck.

Almost there.

That will give you 300s of on time at your set speeds at your set temps.

You can...

If I was you splice into the CAN wires in the harness right by the ECU and just have a second OBD port, could that be a work around?

So is this an issue with all the 2021 GM vehicles or what? I'd dealing with a truck but wonder if the cars are like this too. You can scan via the OBD port but can't write to the ECU. I had to make a...

HHP has a solution for the untunable 10spd's with the T93 that totally works. I bought one thinking it would work for the T93 8spd trucks but it does not. Want it?

Update. My HHP unit works great now but had to be plugged into a cars wire harness to read. My bench harness did not work at all. BUUUUUTTT now I understand that this HHP modified T87 is only for...

Welcome to the nightmare. Let us know what you get to work.

I got an HHP unit and can't get it to communicate at all. This is on a bench harness but I have checked every wire and pin on it a hundred times.

I think the days of great GM performance ended...

What if you 'Y' the wires out of the position switch to satisfy both modules?
Somebody needs to solve this T93 problem. They are starting to use it a lot.

ECM exchange question-
Can the L5P ECM we send in be from a different L5P truck or does it have to be the actual ECU out of our truck?

Does HP Tuners have ability to tune these yet?

Thanks HPtuners
JTEC Jeep tuning!!! Whoo hoooooo!!!!!
Bring it on.

Hmmmm. Neither of us have Regulator Gain or Regulator Offset tables in our tunes. Are we supposed to or is that gone in these new Gen5 ECU's?

Yes, I hadn't actually tried those numbers I said. The point is to just set the Apply Ramp values up much higher and it seems to really lock up.

So I was having this problem too. Think i figured it out, it was a lack of understanding the most important table for TCC lock up. Apply Ramp. The psi you are logging for TCC lock up is simply how...

UMS tuning

I've got some use for this. I have the SCT Advantage software dealer pack and we tune these JTEC PCM's with that. We've done quite a few at the current price point of $380 for a handheld+ whatever...

Are these the red striped ones? I think they are fine, I've tried to tune way way way worse (Deatchwerks OMG). I run 43psi at idle though, I'm sure that helps some.
I've tuned lots of ID1000's that...

That all looks like it should work fine.
I think you may have a viewing issue in the scanner.

Is it possible to keep closed loop up to a point and then have it go open loop? Cause the only way I can see the open loop Airflow Gain table being usable, would be to turn closed loop off completely.

I assume you have a higher stall converter? Otherwise you're just going to overpower the brakes and start going.

Set the top number to what you want and the bottom number 200rpm lower than that.
