I modified my stock ls2 injectors (de-capped) and had them flow tested, 730 cc/min @43.5psi, so 80.4lb/hr @ 58 psi. The fuel rail is corvette style filter/regulator and 58psi. I took my 80lbs divided by 2 and made my entire ifr table 40. Increased my stoich by 2x and halved the ivt. I have done all of this to accommodate the turbo setup I am
working on.
When I start it up and drive it it operates at 14.7 via my Wide band but some pretty big Ltft at idle and in pe it goes very rich. If I try to switch to a speed density tune to tune, the idle afr is very lean (19-20) so I have not driven it like this. Afr error was reasonable before the injector change and nothing else has been changed.
My understanding is that this method worked quite well and that I shouldn?t need to tune my ve/maf or scale the whole tune Is this thought process wrong for the E40 ecu? Should I adjust my ve and maf right away in advance mode or have I missed a step? Or should I just proceed to a full %50 scaled tune.
Thanks for the help. I can post up a tune later. And I do also have a stock tune I can revert to.
