For anyone that is curious or cares. HPT fixed this issue in the latest beta. They sent a email out to me this morning acknowledging the problem and they got it fixed. Not a major issue but happy it...

Awesome. Well appreciate the info. Good to hear someone else had the exact issue helps ease my mind for sure. Thanks again.

Awesome. That was my plan. But I’m a overthinker and didn’t want this to cause a issue. I was confident it wasn’t actually commanding that. But definitely something that makes you scratch your head...

I agree it?s not. I can tell by just how the engine sounds and what wideband is showing. With that said is there any fix to make it read correctly? Did you just tune it using EQ error? Obviously AFR...

Another thing to add before I attach the file and log here soon. I don’t believe the ECM is actually commanding 8.25 AFR. I think the scanner is just reporting it incorrectly. With wide band in...

I do want to add to this that the engine temp has been all the way to 200-205* with no change in commanded AFR.

Have a extremely odd issue. I have used the same Commanded AFR PID for years without issue. Have a 2016 Sierra that is a 6.0 LS based engine with a E78 ECM. Logged the truck bone stock zero changes...

This discussion is more about how/when to dial in the torque model correctly.

I am referring to vIrtual torque coefficients. Not virtual ve. The coefficients I am referring to are under the torque model tab.

Bump for any other info.

Bump becaus I think this would be nice to have also

Yes me and you have talked on fb before I believe a while back. I have done that several times also with no negative results. I have just been reading a ton of info on the subject. I’ve gotten...

I am mainly curious on how most edit the model. Whether they just edit the airmass a b c d by the percent they believe they need to get the model correct and then hand smoothing under the...

Ok so I feel like I have a decent grasp on the torque model but just wanted to start a thread on it again. I have read a ton of stuff that seems like Ghuggins and Higgs are always on. I have seen...

I would put the trans side back to stock and finish tuning the engine side correctly. Update the file for the gear change if you haven’t already. After the engine side is done correctly. Start tuning...

It seems like it may be. Thanks for the opinions guys. I appreciate the info.

The original ecm/tcm would be installed back in the car if it had to go back to the dealer. The separate tuned ones would not be left in the car

Guys that have bought cars with warranty and tuned them. I have someone asking about buying a seperate ecm and tcm. He would like a seperate tcm anyways so not having to deal with downtime from...

Thanks for the advice guys. Going to play with it some more later this week. I’m sure it’s a too much fuel issue if it’s not mechanical. Considering it will start right up if you “flood clear”. I...

Have a 2003 SS silverado that has a TSP cam. Truck drives fantastic fuel trims are all perfect RAF is dialed in. Starts great when hot and cold and everywhere in between. But if you start the truck...

Yeah will post a log of idle in park and in drive. It’s more of one of those things I feel like I know it’s false but just want reassurance. Haha. My cammed and lsa blown gto didn’t have hardly any...

I have a g8 gt that has Kooks headers. Btr stage 2 cam. Magnaflow catback with muffler delete. Car drives well doesn?t stall or surge(if it does surge any it?s a very minimum amount on very first...

Agreed. Was just trying to make sure 22ish wasn’t pushing too far on pump 93. But yes a dyno would help some we plan on going to the track here soon.

2015 l83. Truck is right where we are commanding with fuel at 12.8 wot. Fuel trims part throttle are dialed in. Med and High VVT tables have been changed to the same as the low baro. WOT VVT is...

I have a 2015 l83 silverado. Only mods are intake and longtube headers. Fuel trims have been cleaned up at part throttle. I have targeted 12.8 afr with it being a daily driver and have 3rd gear...
