This does eliminate the issue, but it also introduces the issue of not allowing the computer the ability to remove timing for knock events, as well as different atmospheric conditions. So unless...

Yes, off-road no cats.

Yes, I have messed with the throttle flow tables. Usually I get these dialed in to where I have good idle characteristics with reasonable ignition timing values during idle...

I have been trying to come up with a way to keep ignition timing from running very low, even negative, for a period of time after startup. I've seen it in every Hemi. I know that it is used for...

I have to agree with you. I own a shop and we build and tune cars every day. Tuners act like it's intellectual property, but my opinion is different. If that is their intellectual property then...

Very likely you are hitting a toque limit. I don't have time to look at the data now, but more than likely you need to work on torque tables or torque limit tables.

We have been trying to contact someone from support for 3 days now regarding flashing a 2020 with no luck in getting a response. The car is sitting here to be tuned and we have no answer for our...

Any chance someone might have a stock tune file for a 2014 Grand Cherokee Summit with the 5.7 and 8 speed trans? Need to compare a modified trans file to a stock file and I don't have a stock file...

I actually took an approach basically identical to what you just described on a test mule last weekend. I had been thinking about it and remembered we had the ability to control the estimated tq...

One of the biggest issues I have with these transmissions (specifically the 8HP70) is hitting torque limits after doing heavy engine modifications. I can get around it by disabling a lot of torque...

So upon further testing (and some thinking about what was happening), I found that the Short Runner Valve is switching when the cam timing is advanced beyond certain points at certain RPM points. ...

Last week I was tuning a 2011 Challenger SRT8 6 speed and currently doing a 2015 Challenger SRT8 6 speed. Both cars are giving an issue when advancing cam timing. Let's say I run a flat advance...

Not sure if you stated earlier in this discussion, but what fuel are you using on this setup?

Got my thinking twisted on it while thinking it through I guess. This makes a lot more sense to me than the way I thought it was working so I'm much happier using this mindset anyway.

Ok...the fact that you are priming the system prior to starting eliminates all of this. I'll think a bit more about it.

Keep in mind on the cranking, the initial injector pulse tapers off as the car cranks longer, so if the fuel pressure is taking time to come up that could be causing the issue. I'd check to see what...

I've tested this in the past, but thinking about this now I don't think I was testing things in the way you are talking about. I believe what I was trying to do was find a way to get a target...

Yeah, I don't have a WiTech, but I do have a really good relationship with a local dealer and they will flash them for me when I need. I'll try that in the future. All of them that I've had an...

So Lambda is not changed for fuel type and stoich values are calculations off of Lamda. Dialing in injector scale should not be affected by stoich setting. If fuel trims are off by 10% the type of...

I've been reading through this whole thing. Honestly there are so many different people having issues here I had trouble keeping up with who was having what issue.

I do agree with you about...

I have to question the stoich part. Setting Stoich does not change closed loop fueling from what I've seen. It does not seem to be a targeting value, but a value that says it is the base for adders...

I've gotten to the point I just remove the ABS fuses. When looking at the fuse panel under the hood remove the 40 and 30 amp fuses at locations 5 & 6 (you should double check this...it may be 4&5). ...

The log is much different than all of the cars that I've seen with an issue, but it sounds as though you've had to go through the same thing I've had ended up doing to repair it. All of the PCM's...

This is a perfect answer....I've tried so hard to explain this to so many people and everyone gets so stuck on it being perfectly flat. If the mounting bar was milled down to make it thinner, then...

Oh, you were fine....I just mis read your sentence. It said Lambda not FA Ratio....I just saw the numbers and was really confused until I realized it was Lambda. All my fault man.

I had to read this a couple of times. When I saw what Lambda you were suggesting to command I was thinking in my head FA Ratio. I kept thinking that is pretty lean for a boosted engine....but then...
