Jeeze… I almost had heart failure!


My voltage while I’m running down the highway is 14.2 V. That should be enough right?

Ugh… what are the odds of that happening? Sounds like I should avoid putting the transmission tune on it.

Hi everyone,

Very quick question: I happen to have my original ECU and my unlocked ECU. Let me throw this out there.

Say I install the unlocked ECU and begin to tune, and then disaster strikes, the tune fails to upload and I can’t restore to stock tune. Would I be able to just simply remove the ...

It was Mike. Everything updated perfectly. Sorry, forgot to follow up on the post.

BTW, was going to call to ask customer support but I’ll just ask you here. I did the core swap exchange program, but I’m approaching the 14 day limit, because I haven’t had a lot of time to finish swapping out the ...

Hello all,

I went to update my T2 before another attempt to swap my PCM and finally tune my vehicle.

When I connected my T2 to the Windows PC to update I got a prompt that it failed to connect to the server. I tried it the Wifi way and I got a prompt: DOWNLOAD OF UPDATE FAILED. AN ERROR OCCURRED ...

Is silicone lube ok to use around electronics?

Thanks Mike. I’ll give that a go and see what happens.

Hello, all

I went to remove my factory PCM on my Chrysler. Disconnected the battery, removed the cowl, unscrewed the 13 mm bolt, etc…

Following all the videos, I pulled the PCM out, pressed the center button, pulled back the latch on the connector, but the connector was stuck on the terminal. I ...

P1400?! Why would you assume that’s what I was referring to? :lol:

All kidding aside, you read my mind!

Yes, according to many sources Diablosport licked that one a while ago. I think it only pops up if you were to switch the PCM back to the stock one. Mikel, correct me if I’m wrong.

Still, I ...

Thanks PJD,

BTW, while we’re on the subject of codes. Do you know of any ODB two scanners that would clear any hidden codes that only the dealer can see?

I was looking into buying this:

So it sounds like if it does for the code, it would be as simple as using the Trinity-2 to clear it with the diagnostic tools?

Would you know what would cause it? Is it something to be concerned about?

2022 Chrysler 300S V8

Bypass cable installed, went to hook up my Trinity-2 for the first time. Just for giggles, I decided to run a diagnostic test with the T2 before I loaded the factory data in prep for the tune. I had no MIL light beforehand. I just wanted to see.

The test turned up U0100. I ...

OK, thats what I figured.

Good evening,

This might be a stupid question, but I'll ask:

To get the calibration ID so I can enter it into the form, do I have to have to pull out the stock PCM to get it, or is there another place I can look without getting under the cowl?
