Edit: If you're having issues tuning 42# SVO "Green Tops", skip ahead to my last post.
Hi all, you guys have been a help this spring. Now I just installed a set of 42# SVO Green Tops (M-9593-f302 FRPP, 0 280 150 558 Bosch). I have the Greg Banish DVD and with the injector data spreadsheet. I had the stock 28# inj (GM 12561462) and had the inj data in the tune from the DVD.
I should be just fine bolting the new injectors in and flashing in the new injector data, right? Thats what I did and its VERY lean. I let it warm up (in closed loop) until the LTFT stabilized. Which was 25% (IIRC that is maxed out) to hold 14.7 ish on the WB. I restarted the car, turned off CL with the scanner and reset fuel trims. AFR jumps to 18 and with small revs it will completely lean out the WB (21.9).
Attached is the current tune file. I didnt save the short data log but I can record another one if need be.
Im thinking I need to completely retune my VE and MAF tables now. I should work on the VE anyways since I had issues with the 2200 rpm range previously. I am trying to get ready to run my 100 dry shot but not until this is fixed.
Thanks in advance
