I tried one of Brads last tunes this weekend in SCT. I even did another crank relearn after I went back into Rev67. Drivability that I just got back in Ryan’s ReV8 file with crank relearn was lost. It was lazy shifting and felt off. Shifts were rougher but not by much…just off. A big step in the wrong direction.
I tried it bc SCT has notoriously been the software for all the EcoBoost SHO’s. What I’m up against now is HPTuners limited support in comparison despite it being overall such a more capable software.
I believe every 93 canned tuned blows by 368 engine brake torque …that’s a stock limit. I’m in a software prison right now with the limiter paths not exposed.
Brads tune did learn some and improve some on my way back home from the restaurant we went to. About 25 min one way. It felt more powerful as it was an 18 or 20 psi tune but I immediately regretted it bc of the drivability I lost from Ryan’s tune. The lazy shifts and stuff are just so unattractive since it was literally perfect for the first time.
We stopped on the way back to take pics.





I also tried another hobbyist model calibration in HPTuners the day before and also lost drivability I had gained. But hit the same engine speed limit path.
-So I got drivability back in R8 after crank relearn. Hit engine speed limit.
-tried another HPTuners model calibration and lost drivability and hit engine speed limit.
-flashed back to stock, then back to Brads Rev67. Gained power but dead system DTC’s all back and it also didn’t have drivability despite a crank relearn first and the car mechanically healthy. But to be fair Rev67 was chasing bad mechanical health…so maybe Brads first power tune after engine break-in when he believed the system was healthy may have been the better file to try.
Either way, Ryan is going to nudge Eric Brooks again today. So either A) Eric finds everything (which if he has time to look I’m sure he will) and we unleash this thing finally. I prefer A bc I really like VCM scanner and how I can go through files.
Or B) tell Ryan to put the shiny cool tool down that can’t turn the bolt….and use the tool that fits already and already has exposed the levers needed which would be SCT. At some point you just use the damn tool that already works.
I also tried to setup scanner to log Brad’s file in SCT and it kicked me out of all channels except SAE channels. Which were only 3. I went back and tried to make a new list and there’s only like 11 channels that are SAE. So pointless to log in scanner with SCT. I remember hearing that’s an option. Well I can report…not really.
So soon…more channels in HPTuners?
Or back to the tool already capable, SCT?
Ppl who just shout…it doesn’t work with no context. See when you actually have experience in 10-12, “doesn’t work” isn’t accurate.
It worked great drivability was the best so far…power wants to rip, channels are amazing to log but right now it just appears some limiter paths aren’t exposed. But it’s actively being taken directly to Eric Brooks. Not a customer support ticket. Ryan directly to Eric.
13+ seems like it is supported enough to work though.
