Hey Guys My Ecm is shot. I don’t have my original tunes. They were PPEI tunes and I sold my v2 autocal. (PPEI won’t send them to me because of lawsuit)
So I have a new(to me) Ecm for the truck I found on Facebook marketplace but don’t have a stock tune file to send to the new tuner so they can send me new tunes.
Please help
The truck has a bigger turbo Danville 68 stage2r
And all the intake piping from Pusher Intakes. So it will throw maf code unless tuned.
Background on Ecm failures(atleast that’s all I can figure)
Prior to be determining the Ecm was bad. The truck blew one of the main fuses on the firewall that connect the two batteries. Lost all power.
I replaced fused 2 days later. Drove truck 3 days later. Same thing. Hard suge blew fuse again.
Replaced it with a bigger one.
Drove for maybe 5 days then started doing weird things one day driving
Temp gauge was acting erratic. Jumping up and down and kept throwing check engine light and loss of power.
Grabbed my scanner got code P0652,P0193,P0183.
So I replaced. Fuel rail pressure sensor. Fuel rail temperature, coolant temperature.
Still truck gauges are acting erratic.
Fuel,coolant,oil pressure all jumping up and down while I try to drive it.
Would love if anyone could help me or advise.
Do I need a new Ecm ? Is it something else ? I’ve checked wiring harness. Nothing looks damaged. Changed all the sensors besides the fuel pressure regulator.
Would love help with a stock tune and or any advise.
