Im just finishing up on a h series motor with an h23 crank and rods with everything else being close to stock h22 parts. Im kinda new to ecu tuning and i just picked up a p72 ecu. The problem is i cant find a basemap thats set up for this motor. Would I have to set the timing for an h23 motor and then setthe rest up for the h22? Grrrr. Im a little frustrated with finding reliable info, some of the stuff out there is good if you can filter through the BS. I have a 50 shot nitrous kit for it as well but im not gonna install it until i get this figured out, but if there is anything i might need to know on the basis of tuning for it that would great. Thanx much!
