Hey Guys, need a little help here..
This is my first time using HP Tuners and is my first tune AND first fire up on a 6.0L LQ4 swap into 3rd gen Camaro. I'm using an 0411 PCM.
Engine is stock except for 2002 LS6 cam and PAC springs. It has 317 heads.
For the base tune I started with a stock 2002 LS1 F-body manual trans file.
Used 2002 LS6 vette VE table as heads are very similar to 317s and should be closer to start for this cam.
Inputted DW Injectors data for 60lb/hr injectors [PN 18U-01-0060-8 ] that flow about 76lb/hr at the 58psi fuel pressure:
Data = Voltage Offsets vs MAP, Flowrates vs MAP, Short Pulse Adder, Short Pulse Limit, Minimum Pulse Width
Kept stock LS1 timing.
Changed to 2bar OS, NO MAF as plan to boost later and figured I'd start with this. Yes I have the 2 bar MAP sensor.
Changed displacement to 6.0L [0.74590L per cylinder]
All else stock in the tune except fan temps, rev limiter, abuse tables, codes disables, VATS etc.
The engine fires up immediately, then stalls out after a few seconds even if putting in some (half) throttle.
It almost tries to idle, but stalls if add throttle.
It will fire right up again on the next try.
Checked all coils & injectors wiring right to PCM.
Checked fuel pressure (not running, key on 57psig)
Compression is 160-170psi across the board.
It reeks of fuel after starting.
Pulled all plugs, all the same..very black.
I have attached the tune and the Injector Data.
Any ideas or help on this one?
What else besides the VE/displacement/injector flowrates would cause the fuel to dump into this thing?
