If anyone can identify the gremlin here... I'll be your huckleberry. LOL.
Above around 0.80 throttle voltage and higher speeds (usually 70+), if I dump the throttle I will get fuel and timing cut....

So... long story short. I've been battling this annoying problem for a while now.
Cold starts are always perfect. I can shift into drive or reverse with no issues.
On a hot start, the car will...
The ability to disable o2 sensors is also missing from the Beta Editor. I have a feeling this is related to the current emissions uproar.
I can also confirm that Aircharge is missing from the Beta...
Has anyone tried to launch a car with the converter actually unlocked through all of 1st gear? Or launch in "slip" and max slip out to 200 rpms?
In both Sport and Track mode, converter lockup...
The TCM doesn't store the VIN. You can freely swap 8HP70's in and out. I have a 2019 8 Speed from a 1320 car in my 2015 Scat Pack.
I assume your still running in closed loop. Fueling is a major factor in idle quality and I've found that larger cams like to idle on the rich side to account for the overlap.
In closed loop, the...
I sent you a PM about a BCM issue with a 1320 transmission swap into a 2015.
I just installed a 1320 transmission from a 2019 Challenger into my 2015 Scat Pack.
For the most part, it is working really well.
I'm running it on stock settings with the exception of output...
My HCI 392 runs really great on E85. My actual ethanol percentage hangs around 77% at my pump.
1. Set Stoich to the actual ethanol amount. I tune to 0.84 lambda on my car, but it makes the same...
Just completed my return line setup on my 2015 6.4L Challenger.
Attached is the offset data that ID specifies for you to use with a non-vacuum reference setup (Stock).
Basically, ID tells you...
I ran open loop for quite a long time and had the car running really good. AFR error was always between +/- 1-2%.
It took a lot of time to do this and you really need to run dual widebands (tune...
Has anyone experimented with adjusting converter lock up for launch at the track?
I run in Track mode and my street data shows that Track will shift faster than Sport mode.
However, Track mode...
My car is a 2015 and I recently had #3 coil pack die on me. P0300 code and it finally popped a secondary circuit code for #3.
It would run fine at PT, but would stutter and miss badly at WOT....
With my 2618 drop in pistons, my sensors have always been pretty active until past 5,200 rpms. I have recently switched over to E70 and it made no difference..... even with a stock-like timing curve....
The Idle Torques will solve this. The car likely has a ton of timing movement.... this really needs to be limited to keep the idle relatively stable.
I set my minimum timing values to 2* in the...
Try leaning the fuel out to around 12.5 - 12.6 The 6.4L seems to be prone to fuel knock.
If reduced timing eliminates the knock events, I would be extremely careful with desensitizing the knock...
Yeah, it's a absolute pain to deal with. It takes quite a while for it to normalize.
Do you know if the temperature defaults to coolant temp after a flash or something else?
I've read that GM...
Has anyone had any success having Injector Tip Temperature added to their configuration? After every reflash, I have to wait for the excess fuel to dissipate before I can start logging. This...
I'm currently using a MVPI2 with Pro Link. I have a wideband setup on input 1 and input 2.
I can log both of them together fine; however I can't figure out how to setup a AFR ERR histogram for...
The PID system in the idle torques can help with this.
If the idle is very stable, try setting the throttle proportional in Drive to 20 at -100 and ramp it up maybe 44 at -500.
For the time...
Bring the idle up to 850-900 until you get some stability. 725 will likely be to low period.
First off, you must ensure idle airflow is correct.... then you use the Idle Torques to stabilize the...
Set the exhaust WOT to 134 from idle to around 4,800 or so.... then retard the cam back 4-6 degrees to 128-130 by 6,500 rpms.
If you find a dyno, you can actually retard it back until it doesn't...
Thanks. I'm coming to terms with this. The car runs great... who cares what the table looks like.
I've always tried not to "hack" tune it..... crazy PE, etc.... but the VE is what it is.
Yes, 222/230 112.5
I disabled VE learning and it seems to have helped some.
No matter, the AFR Err is typically <2% for the VE tables and is often <1% in most places.
Decel has been one of...
Anyone have a Challenger 1320 stock tune yet? I'm curious to see the TCM settings.
