There is a flash fix for the temperature issue from gm. It will need to be updated by them. #1 egt reading -40 would be from a bad or disconnected sensor. at egt1 location.

i work in a bus garage. We sell new units too. Ill get a file out of a e450.

12v cummins wont have an ecm. nice trolling....

Ill do that tonight. Im getting back to my own projects right now. This is one of them. Im working around a worn out stock allison. I fear im loosing the fight. Need to log the torque to keep this...

Need more info about the ecm your using. Im guessing this is a swap tune your needing? or help building one? Im not on here very often but will check back on this in a day or so

I have an older version of HP. Im trying to log and tune my own duramax truck. Trying to get the defuel logged and set properly. There is no engine torque pid available for logging. I kinda need...

i could see that happening. My wifes suburban came with a referenced regulator system. I broke the intake (long story) and only had the tbss intake and rails sitting here to get it running. I threw...

Do you have a scan tool and need help? Have you taken it to a professional technician? You might get better help over on www.gearhead-efi.com . Lots of guys over there with obd2 lt1 stuff. I also do...

the last 3 or 4 corvette regulator swaps i tuned were actually 66 to 68 psi. change your injector data accordingly and recheck. my .02

Mine goes to 95. you need to max out your torque limits in the driveline torque menu. Then relog. If its not that the smoke limit table for egr on/off tables need adjusted. You can do the tbiq...

When you have a cam with lots of overlap it best to spray after the exhaust is shut. It sucks not being able to take advantage of the evaporative qualities of the fuel hitting the back of the valve,...

i reread your inital post. I missed it the first few times. The baro update becomes a fixxed issue whn updating to the custom os's offered . Using a 2 bar os with a 3 bar sensor is wrong. A 2 bar...

That engine in base form was known for eating injectors. the fuel pressure regulator was also known to rupture randomly as they weren't meant for e10 fuel. Clear your fuel trims and take a log of it...

whats really stopping you from using an older ecm?

Ben C

I'm gonna edit that for clarification. I have it in tunercat 2 and can confirm with snap on scanner it works. Looks like we don't have it here in hp tuners.

There is a baro update...

edited and moved it down.

Hey guys don't forget about the 07 motor being 58x reluctor on the crank and 4x cam sensor IIRC. Why not fix the 5.7l?

In running some diagnostics on other units with this FPCM, the pin 13 is a power signal from the ecm. Still unclear on exactly what it does that a communication signal couldn't do, or even the need...

I have not been able to get a grasp on the virtual VE, but have been trying to understand the numbers in relation to cylinder pressure. Im probably going to try a running compression test and move...

so i have to repeat the process for each main(pilot and non pilot)' then the warm, and then cold tables? im tuning an lbz with tunercat 2, so please forgive me for now. hptuners is my next...

I have worked on vehicle that needed the TB cleaned after I finished a log and found the idle minimum % for airflow was at 21%. This was on a 4.8l half ton pickup lifted with huge tires. Cleaned the...

Post the tune files if you have them. Do you have hptuners?

In a nutshell the system is displeased. Fire up the vcm scanner and try to connect to the feul pump control module. That code means there is a stored code in that module. Possibly you missed a dtc. ...
