Youre right. Its a gen 1 tune. The amount of MPs verifies this. .82 lambda at WOT should be stock with a stoich of 14.08 at higher RPMs. Look at a...

changing a file name does not effect license license attaches a interface to a serial number of a controller and its VIN

Some ECM's will have "pull up resistors" So its possible to see 5 volts on the Signal pin.

Well, I don't think that it's the TUTD settings that are causing me grief... my issue is that the TCM loses communication intermittently. In the...

The tune is pretty much stock comparing it to the stock file you posted except for some idle tuning and higher rpm MAF changes. <<<the downshifts...

Tommy, did you get Bluetooth to work?

Well I think its at a good place for the moment peak power is defiantly way up and it shreds the tires pretty well. I need to do some launches vs...

So I am confused on the licensing. if you change name of .hpt file it has to be re licensed? or things like segment swapping have to be relicensed?

Man ... the mobile version of this forum is horrible! I was trying to edit some wording in my previous post, but the forum completely deleted it...

Look at the screenshot closely, in the channel listing. Don't look at my custom EQ Chart, as that's math channel .... The Equivalence Ratio...

Did you figure out the issue just replace lifters and cam on a 2021 Silverado same issue will die when warm and start right back up next morning I?m...

There is still a ton of burst knock enabled in that tune so if you see KR it might not be real knock. Timing doesn't seem excessive or aggressive to...

That?s kinda where my head is. Some minor adjustments and some corrections to the spark tables. I think the pro got way too aggressive but there...

anyone got a good fob e85 6speed tune for 2021 s550

well having a entire spare harness avialbe to me (came out of the donor motor) here is what I can tell you. The three wires form that sensor are...

not a big fan of those dd tables looking like that but it turned out to be the Peak tq numbers. I bumped them up 10% and it cleared it up. Thanks...

were you able to do whatcha wanted to do???

or it did and your 7% neg trim pulled it back out? remember, there is all sorts of lag happening... some of it is just the time that it takes...

Just thought it may be something to look at for the next guy.

Don't log with "SAE" parameters, they don't work well in GM gen 5. The reason of the timing is because your minimum spark tables are set to 12-15...

No. It's ridiculous to think you have a wire shorted in the harness somewhere and it has exactly 5 volts on that circuit. It sounds like you...

Thats going to have quite the cam bearing clearances..

Funny side story. Email customer sends me a screen shot of the cam in his LS. It's a Summit cam, it says LS in the title but the picture in the...

Yea I don't normally do that stuff. I only copied all of that trying to fix this issue since I knew that my truck didn?t do this. It started off with...
