Awesome update, misfire minimum timing is finally explained...and now disabled. Thank you
I know "Torque CRV Limit" on my truck truck was caused by reaching the max value in the pedal map.
I can't help you there, I haven't tuned an 04.5 up truck yet so I don't know about the baro problem. You obviously have a lot more tables/limiters in your 05 ecm so you may not have to disable them...
Bamofo, do you have any fuel quantity protection factors under the Injection Quantity tab still enabled? I tried to leave some of those enabled at first but it wouldn't rev much over 4k rpm until I...
Or just disable pilot over 3000rpm since it really isn't needed up there anyway.
Tried, but I didnt see an option for attaching tunes in a pm. The fact that it pulls out of it almost leads me to believe it may be a timing issue, as in too much timing in that range that it is...
What exactly is it doing? I know on mine half the time I have to disconnect and then reconnect a few times before it starts working.
Alright, did some further testing. Raising the extreme cut off up to 6000 didn't change much, still only made it to 4925 rpm. So to test the pedal map limit, I rescaled the pedal map to zero out at...

Basically under light throttle and cruise regions. Once load gets to around 25 percent the misfire minimum timing seems to drop into the negatives where it won't affect anything.
Here are pictures of where I had the limiters set at.
Very well could be, it was still pulling when I let off but that could be because I let out of it right when the limiter was starting to kick in.
I'll take some screenshots, I had the enters maxed and the exits a couple hundred rpm lower. Also had the extreme cutoff still at 5500rpm.
What I basically did was max out all of the DFCO limiters and then used the pedal map to control max rpm by setting the last rpm column 100rpm higher than target and setting that column to all zeros....
I think he means switch on the fly tuning, like a csp5 switch equivalent.
Figured I would bump this back up in case anyone can shed some light on it.
Try putting your Pilot Quantity ECT Coefficient table and your Pilot Timing ECTxIAT Coeffiient table back to stock.
The stock early 04 log I posted earlier in this thread should have the same pilot tables as an 03.
Take a look at this tune and log if you have time. If the pilot tables are max limiters, this...
It would be best to send your tuner the file with the OS patch. One time after applying the patch it would not allow me to load a pre-patch tune. I don't know if it was just being glitchy or that is...
If the output pilot SOI was the greater of the two, it would leave you with a theoretical 150* of pilot timing with the stock 04 maps if you were between 180-223 degress ECT and 80-100mm3 commanded...
Thanks you for taking the time to make this up and share it, much appreciated.
So what you're saying here is that you need to subtract the base table timing value from the adder table value, and then apply the coefficient?
Could be, it is definitely close. FCA duty cycle desired seems to be pretty worthless, milliamps is the best way to see what the FCA is doing.
I don't think it is showing the milliamps, although looking at old logs of my truck they are within 100 of each other. Mine was doing the same thing, but it would actually start creeping up to 12-13k...
Just for curiosity's sake, what is your lift pump pressure at idle? After looking at this it looks like the ecm is trying to max the milliamps to the fca to keep rail pressure in check and it appears...
