Called an ECM bench. Used to test calibrations in house before playing with the car. Helpful to figure out why code does things when certain inputs hit thresholds. Thats how we discovered things like the MAX ve issues with $8D on injector pw.

I was thinking about one of those A piller mounts, I really don't like them, but can't think of a neater install. He's going to teach me the ropes of tuning as he does mine, and suggests that the FP guage is a requirement.
Comments, suggestions?
My fuel pressure gauge is in my engine bay. The only reason I'd ever need to see it is if I suspected an injector or fuel pump fault. I set my fuel pressure to 50psi at baro. I expect a 1:1 rise with boost. You are N/A.. I'd set your fuel pressure to be about the same but you have a few other issues to combat.
1) Injector size 2) Max VE
$8D shows BPW in the datalog, not final injector PW. My code is patched to display actual final PW, so I'll dial my idle in to get the injectors to fire a reasonable PW so I can get away with higher fuel pressure (for better atomization). Plus, I can run a smaller injector which is really my main goal.
I also have code mods to my bin that runs open loop until 1400RPM, and I've altered my 02 swing points for open-tps closed loop operation so the corrections are closer to my desired AFR.
Your combo I imagine is harder to tune than mine..
