I have read everything I can find in this forum on this topic. I still want to confirm a couple things. The premix ratios I read...100:1, 125:1....is this for an engine that has the OMP removed or is this to support an engine that has the OMP in place, but is not really working because of the Haltech system? I need to get this all straight. I'm in the middle of a rebuild. My shop doesn't like premixing to the point that I have to sign a waiver because I won't buy the PFC to replace my Haltech. I won't get a warranty (won't get a great one anyway, so no big loss there really). As of now, the engine is assembled but not back in the car yet. The OMP is in place. Should I keep it in the engine? Should I have it removed and blocked? Should it be in place but unhook it electronically? Can someone spell out these ratios for these different scenarios please? I don't mind premixing at all...doesn't bother me a bit....but I need to make sure I have the info straight....is 100:1, 125:1 too much premix if my OMP is going to be in place?Wiil my OMP be doing nothing or working part-time with my Haltech? If it's left in place, does it have to be unhooked electronically?...I don't want too much premix...foul plugs, detonate....I appreciate any help...thanks....
