Which is what I said, minus the theoretical part. Theoretical means it can't or hasn't been proven. MBT can and has easily been proven. By definition, it is NOT just a theoretical number.

I love the flex feature but I’m afraid hpt isn’t the best software to make it work.
Be careful with flex on these. There are 9 parameters for fuel system fuel volumes that are typically defaulted to 0 lb in the m6g. The problem is that when switching fuels on a fillup, the logic...
So you have 3 issues remaining? Occasional bog on 1-2 shift, dying when coming to a stop, and low WOT timing?
If the tune is hacked together, it might make sense reverting back to a stock file...
MBT is a physical characteristic of the engine, being the timing at which it's most efficient and makes the most torque. It's not just some theoretical number. The tune should be calibrated to...
Im assuming you mean max load, not just load in general which is always changing. At any rate, if you lower compression to, say, 9/1 then MBT will be much higher. If the MBT in the table isn't...
The mbt tables really shouldn’t be modified much from stock unless you make some major change to the engine like compression ratio or cam profiles. Some tuners just raise all the mbt tables by some...
This sounds just like shift torque modulation. You can log more stuff to learn more about whats happening but basically its cutting spark to achieve a target shift torque. You can change the shift...
My 2020 does but it’s a Roush os.
The pcm doesnt have the ability to sense or calculate non-baro throttle inlet pressure. It thinks it’s only 0 psi there, so it opens the throttle appropriately but inadvertently lets all the boost...
If you?re sure of your injector data it?s pretty straight forward. You just have to modify the maf transfer function and your goal is for the average fuel trim to be close to 0. You can make some...
You could try using the slip tables again but set the slip to 0 rpm in each gear.
Rob, the method I posted above prevents it from using S (spark retard) and A (air/fuel) to modulate torque. It has to resort to I (ignition cut) to reduce shift torque. I’ve tested it and it works...
Yep, my mistake....fixed it.
Thanks veefour!
I’m looking for a manual one.
You basically have to force the SAI system to skip S and A and go straight to I. To do this, you'd have to set Shift Modulation to 1.0 in table 33458 (spark only torque ratio) and confirm Shift...
I dunno man, you didn't list the shift points in the first post in the list of tables that you adjusted. I opened the file and all the shift points are set to 7000-7450.
Yes, I’ve done it.
Dumb question….i see you raised a bunch of limiters but did you raise the actual shift points?
I know this is late but I searched at length for the same thing with no luck. I tried the data from an Edelbrock Stage2 SC kit and it didn't work at all. I contacted Edelbrock and they said to pay...
See post #2
I had to artificially lower my mbt for it to make any appreciable crackles. Also you might need to lower the dfco spark only torque ratio. I think stock is .7, so maybe drop it to 0 and see how it...
The DFSO ramp rate is described differently in competing tuning software. It sounds more like it's a torque ramp off rate. If that's true, then higher would be shorter time. I tried changing mine...
In the exhaust cam, 0 is fully advanced and 50 is fully retarded.
