oh. i think it's MBT spark.

thanks for your knowledge. really appreciate it.

so i finally got to test all this and determined some things then got stuck

i made a big flat area in the min spark table of 7 degrees, set all...

can you tell me why hemis seem to run such low timing at idle in general
any other motor with a cam like this, aluminum heads, and normal compression id be shooting for 20-25 degrees as a starting...

okay i figured it out in theory
spark is referenced against both map and ve (which is itself effected my map)
cam makes less vacuum
idle spark base is pulled from part throttle table
stock spark...

oh right you wanted the calibration. here's the one im mucking with right now, again, not gonna see much. this one has the VE table kinda mangled from me seeing if dropping the VE in idle range...

the journey continues.

so i went back over there and tried a few things.

i verified that the cam does move by 7 or so degrees so that means its a limiter on the VVT not a locker.

i verified...

oh ill post the tune tonight but you won't see much
just disabled codes, vvt, mds, neural net
it acts the same as before tuning, no real difference

i did disable the neural network
one thing i realized last night is i dont know for sure if the vvt is locked or limited
but that still doesn't satisfy me as an explanation of why the idle and...

hey all

i would usually never tune something im not familiar with and i am not a hemi guy, but a local customer approached me with what i thought was a simple issue so i figured i'd just do him a...

rtxloki i have done a 4.0 tune or two

there is no injector constant available in hptuners for that ecm, you need to fix your injectors first. so what you want to do is go ahead and do some...

i ran into this recently too while in vehicle

it looks like its almost always a low voltage threshold, it would be really nice if the kernel or whatever reported that error properly to the...

i am wondering the same thing as well, it would be nice if they were documented, but a strategy of leaving the original value alone or disabling it should work in most cases. i would presume the...
