Can I connect with my older MPVI Pro cable?? Or do I need to upgrade to a MPVI2? I have a 2020 Challenger Hellcat Redeye.

Any updates from HP tuners to get access to torque convertor pids? My 8 speed in my 2015 at the start of this thread was fixed by the dealer at about 30k and now I have about 80k on the truck and it...

New convertor, new fluid, fresh fast learn and the shutter is gone 100%. I still would like to set the desired slip to 0 in high gear if the pids ever become available. Maybe after the warranty...

2015 Chevy Silverado LTZ 6.2L / 8 speed

Any chance of getting more parameters for the T87 8 speed transmission. I have a terrible shutter in the convertor and if the dealer doesn't get it fixed...

Might try lowering the 40 kpa x 1200 rpm cell a little bit in your VE table. Log it again in OL and see what happens. Make sure your are in OL. The STFT Open Loop box is enabled right now too.

Double checked my injector data. I was just a little off on the flow rate table but not enough to make a difference. The offset table looks like I should have had almost .75 at 80 in vac at 14 v...

I have a strange VE table that is needing over 100% values at 4000 rpm and up at only 15 to 25 KPA. It idles with somewhat normal values of around 30% at 800 rpm at 65kpa. I haven't drove the car...

Does anyone have any advise on how to calibrate the TPS VE multiplier table with the custom OS??

Any suggestions?? Does the 02 OS offer more benefit than going custom with my current 2000 Firebird LS1 OS???

If I go custom does anyone have any advise on how to calibrate the TPS VE...

Try Zeroing the burst knock base vs cylinder air delta. Then you will know it that is real knock or not.

Getting ready to tune a buddies 2000 firebird. He bought a 427 ci LS2 with Mast Heads and a pretty big cam (apx 242I 250E). Car is an automatic. It has a 102mm cable driven TB. I was thinking we...

Why don't you look at your Open Loop EQ Ratio Gas Gear and Park tables. There are areas that are .85 when its below 90 degrees. Not sure what your stock tune looks like but most don't go below 1 or...

Your MAF calibration is 10 - 20 % higher than mine. It is also not very smooth.

You have SD disabled at 400 rpm. Usually that is 4000 if your doing a blended tune

PE is 1.22. This is 12.0...

My kit came with 60 lb siemens but that was 2 years ago. Get a ZL1 Map and do it right. That table looks way off and should be curved.

Your right. I was only looking at the first few frames of your scan. I see it going down to 6 or 8 degrees at WOT at 3500. I can's see whats causing that. I would try to log every timing pid you...

Is it really worth the extra time to tune the VE tables and run a blended tune?? I've been running my Whipple Camaro for almost 2 years on just MAF and it seems to run pretty good. Does it make...

Looks like maybe your on the coastdown table at this point. I would think you would want more Idle timing in the Idle base table as well. Log all of the timing pids in your scanner table display...

Trying to learn more about Idle airflow with larger than stock cams but haven’t been able to find any comprehensive instructions anywhere. I am hoping to get some info here to help myself and...

So does anyone see a problem just running the stock 49.8 lb at 58 psi injectors in the maggi manifold???? Didn't really think the change in the angle they install would be a problem but just wanted...

I read this thread when trying to figure out what these pink 0280156030 injectors flow. Looks like they should flow 47.09 at 58 psi but the Magnuson tune calls them out at 43.98. Since that is...

I see what your talking about. Didn't realize the scanner wouldn't work under set conditions like that.

Do you lock the convertor on the dyno usually??? Seems it might be more consistent and...

Thanks James, I think I get it now. Everything is in Crank degrees. The numbers in the charts in HP tuners are in crank degrees of retard from parked. The cam is advanced in the park position 17...

Can you explain to this dummy what exactly you meant about the proper setup??

Also would you dyno it with the stock convertor locked up or unlocked on a 550 flywheel hp (hopefully) 2012 6.2L with...
