Tuning speed density: in closed loop, zero out the fuel trims by adjusting the VE tables. In open loop, create a "fuel trim" percentage number by comparing the commanded AFR to a wide band reading:...
That's good info; I hadn't yet run into that problem but good to know what happens - thanks!
Spark Inverse - are you referring to the "Inv Efficiency" table under the Torque Model or Torque Management tab? (can't remember which tab at the moment). If so, that table is used to retard timing...
If anyone has a PCM that is not applying the MBT table(s) as THE ceiling, then they should be contacting HP Tuners help staff for some explanation.
MBT is by definition the highest possible torque...
Good to know. I will not be verifying that haha.
The PCM uses the MBT as a maximum for all conditions - part throttle, WOT, startup, WOT thermal, you name it. The other spark tables should never command something greater than MBT, but if they are...
I suspect the remote tuner(s) attempted to give you a safe starting point by dropping your MBT spark table from 80kpa and above. Really the only way to get an accurately tuned MBT table is to run a...
I've not had an error code. Some of the stock calibrations command several degrees beyond the OEM cam limits.
Yes, commanding beyond indicates only 14 degrees of phasing.
I personally don't care what a degree wheel may show, because tuning the stock PCM is limited to what the PCM sees and what the PCM is...
My comp limiter setup phases exactly 14 crank degrees.
Ah, good to know. The modified "engine run time" was working fairly well, but I'll look for the new stuff in the beta. Thanks!
I think the best option to get you going quickly would be a tune from one of the pros that has the secret sauce for forced induction on a 3.6 pentastar - maybe hemituna on here...
I doubt any pro...
Well we're building the knowledge I guess. With all the GM and Ford info out there, I'd be more concerned about weeding through all the not-so-good info...
Just log your BFI and you'll see it go up and down as the PCM responds to transients during warm-up. The applied value of BFI won't necessarily match the corresponding value set in the tune's BFI...
I think so. Not 100% sure. The rear O2s Will remain in open loop until the ECT reaches the value in that scalar. I think the DTCs for the cat efficiency etc. shouldn't trip on in open loop, but...
Yes I have used the NNT and it works very well. I'd say it can't be beat for getting the engine to run the way it was meant to run from the factory - drivability, response to fast transients in...
If you disable ANN you should also disable VVT, put your injector tables at stock (Ram 6.4 in your case), and zero out your fuel trims using the two little VE tables. The problem with that approach...
The channel for my exhaust cam angle is called "exhaust cam center position." I guess the name varies, but whatever works for logging the exhaust cam angle for tuning purposes.
Recommendations:
1. Check for intake leaks, maybe on the manifold or throttle body. Sometimes the intake gaskets smash the wrong way and will not seal properly. Just due diligence.
2. Set...
The intake manifold and injectors - are they stock 6.4 Ram or from a 392 car?
Post a log and tune file and let's see what's going on.
Did you update your injector tables and manifold scalar to match stock 6.4?
Are you also using a stock 6.4 throttle body?
Is the...
It may be worth mentioning that in the newer PCMs (GPEC-2) at least some of the calibrations do not use the VVT spark tables. The scalar values you're looking at (where you see the lockpin value)...
I think the Mk82 is .602/.602, 220/228, 114 LSA. I guess one could tease out the rate of lift from those specs...
No, but the Mk82 requires FRP's springs as well, for whatever that's worth.
