Hey guys, couple questions because im not getting much help in the PCM/Tuning page:

Ive got my new stroked LS2 with pro charger all installed, and im trying to crank it over.
It cranks, but she doesnt actually start up.

Setup as follows:
402 CI
243 heads unported
237/25x cam
Siemens deka 80lb injectors (running 58psi base pressure, so theyd be 91lbs?)
Procharger d1 with 3.5 pulley
2 bar map, SD, no MAF

Im wondering if someone can look at my tables, and tell me if they look around correct for this setup?


















Any and all help appreciated, if you need anymore info/tables/pics please tell me and I will post them ASAP. I just really want this thing to run.

I would change the cells that are at 15* in your idle range to 26* unless they are like that for a reason.

Also I would try raising the cranking PW

Have you verified fuel and spark?

Im not sure why they are set to 15, the tune that it came with was just set to that.

With a noid light hooked up i get flashing, and if i pull a wire and hook it up to a spare plug it sparks so i expect im getting both.

Any idea what the PW should go up to? It smells quite a bit like fuel when i turn it over, I almost thought the cranking PW needed to come down (but again, im new to this so..)

Update: Set the timing in the 77-103kpa range up to about 32 degrees and she caught pretty quick, made a about 5 seconds of rotation under its own power (at below idle rpm, maybe 650ish) and then died. Getting a bit of backfire, I feel like my fuel table is much higher than it should be.
Can anyone confirm/shoot down my VE table for 2 bar? I feel its more like a 3 bar table.
