same issue here. 2005 GTO. been in contact with support.
theres no way to tell if the scaling was done correctly unless you have the original tune you started off with. can you post that up?
but like I said before, if the original tune ran OK, then it...
GMVE gets scaled. no question about it. GMVE has displacement "in" it. but it does matter what you start off with. If your original ve (before scaling) had error baked into it because you could...
I have this same issue since I got my car running a few months back, but the idle hangs whether the code is set or not - probably because my ve and idle airflow/spark needs work. I've had no time to...
it will use both the high and low tables. i think the issue you mentioned was with the gen3 pcm.
get the z running again?
Warm up transient fuel: min decay - max decay
Yes.
Transient Fuel Mass:
Really not sure about this one. If the value represents a fuel mass, then yes.
Transient fuel mass impact factor-GAIN
No,...
never seen it happen, heard of it though. this is exactly why p0068 should never be disabled on any street driven car. it is there to prevent something like that.
if they reference airmass (g/cyl), yes.
i have used an autometer sender directly to the hpt interface. it works ok. I forget the slope and offset of the autometer senders but most are the same.
so you want all these issues you are having to continue?
step 1 - injector parameters
you will be amazed at how everything falls into place when this data is correct.
the pcm is seeing too much airflow for a given throttle position/rpm (based on a stock configuration) and thinking, oh shit! something is broken, this car is out of control, im shutting down!
you...
keep in mind that table is an important safety feature that you pretty much disabled. It should be set properly and not just completely maxed out.
Funny, those guys were at the same advanced gm class I went to last year, where greg banish went over scaling for almost 2 hours as the ONLY way to properly use injectors larger than the PCMs limit....
you probably have the injector error compensated for in your ve table. How does your commanded/actual AFR look when in PE or BE?
Im just saying, if you change both those tables back to 1.00 im...
log IFR. 63.5 is a hardcoded limit, the pcm can't go any higher even via multiplier/modifier.
just for the hell of it though, change those modifier tables back to 1, and see what happens...
looked into this a bit more... supposably neither the IFR modifier v iat, nor the IFR modifier v. volts do anything on the E40 (gto) pcm... scaling is the only solution.
probably not. I just find so many people that have boost/vac regulators and dont use them for what they do best with forced induction. if you did hook this line up the you could flatline your ifr...
are you using a boost/vac referenced regulator and is the vac line hooked up?
boost/vac referenced regulator?
yea, give it a shot. wonder if the IFR parameter would show the change in the scanner...
if you're going to run sd, and dont need the extra room on the maf, then it would be a simple solution...
does not work on e40 pcm.
pm me your email ill send you a document that will help with scaling
stock 07 awd?
depends if the aftermarket gauge's sender outputs are the same as factory sender... ive come across some that use a completely different range from 0-5v and some that dont even use a 5 volt signal at...
