Has anyone logged the L8T while heaving towing using 87 vs. 91-93 ? I am curious to know how much KR is occurring octane vs. octane. I know the L8T us setup to run on 87 in any situation.

I assume it's based on the tq% at the current rpm?

If my goal is to not have PE come on unless I'm over 2k rpms under a heavy load what settings would you recommend I change and what would you...

Enable tq set at 60%
Enable pedal set at 60%
Enable RPM set at 2000rpm

I set the RPM at 2000 because I don't need PE coming on under 2000 RPM while cruising not towing.

When I reviewed my...

Or is it using a Throttle position channel?

Any help would be greatly appreciated.

When adjusting a tune it references throttle % in contrast to what ever you are adjusting.

What channel is tied to what the ECM uses when tuning. There are many to choose from. Is it one of the...

I think you are correct. My buddy bought it with headers, high flow cats etc. There is no way to figure out who tuned it. How would I go about making it so it can be tuned? Probably going to put it...

Any help be appreciated.

Trying to pull the tune to see how far from the factory tune it is.

A list of modules pulled up but I'm just getting an error on the ones I tried.

Any guidance...

Good to know. Thanks!

What year Escalade ran an L86 with a 6L80? I thought they ran the L86 starting in 2015 with the 8L90 in the GM SUV's. 2014 Escalade ran the 6L80 but had the LS based 6.2L (can't remember the engine...

Thanks for the reply. I had a '17 F150 I set as low as 20-21mph if I remember correctly. This Yukon 5-6mph higher and I wasn't sure if it would actually take if I changed it. I regularly drive...

Has anyone successfully lowered the min cruise control set speed?

I know this in an old thread, but would you mind posting your file?

Hey thanks man! Not sure how I missed that one.

Either truck or SUV. Looking to compare upshift points with the stock shift points in my 6.2 8L90.

Looking for a L83 8L90 stock tune.

Thank you

When you zero the tables are you zeroing the "AC Off 1st - 8th" tables under "TCC desired slip"? I have DoD disabled so I wouldn't think I need to mess with those tables.

Thank you!

128858 Do I just not have access to this missing stuff or is it maybe some setting that allows me to see what is missing.

Please advise.

Thank you

Would someone be willing to post a screen shot of the desired slip table in HP Tuners on the 8L90? I cannot seem to find it and I know it's there somewhere. Thanks!

Since the L8T doesn't have the provisions for the vacuum pump are you using the Corvette pump or something else?

Any noticeable weight difference going to the L8T? Stance difference or drivability?

Local tuner turned off my DOD/AFM some time ago.

They also disabled my torque converter lockup in the first 4 gears per my request to smooth out light throttle shifts. Worked like a charm.

Did you end up going with a L8T vs. a L86? I know the biggest difference is the iron block in the L8T vs. aluminum in the L86.
