Anyone ever map a Std non HO 670 ignition curve? I know the std and HO/X Summit 670 have different curves with huge differences in the midrange and I'm sure the Summit std 670s have different advances than the std flat land 670 as well but not sure just how much and where in the RPM band? I have an older Aerocharger kit on a flatland/foothill sled "not any mountains close to me :[" and have installed a Microsquirt with a missing tooth crank wheel and I'm ready to swap it over to the Microsquirt for ignition control and need a good base map to start with. I can build a map from scratch if I mark up the flywheel, but the thought of running it up on a stand to 8+ thousand RPM trying to get a reading is a little tricky to say the least. With the Microsquirt I can have the timing stock or slightly more advanced off boost to compensate for slightly lowered compression and also pull timing per lb of boost for long pulls. If we don't get more snow soon, this sucker is getting wheels and a radiator! :]
