So ive finally got my car to a point where it runs and almost idles, i say almost cuz its only 5-600rpm and not very smooth. I have a base fuel curve from another user with a similar setup, but i am trying to figure out my Spark curve, i really dont know where to start except that i set everything in the low rpm range to 12degrees BTDC in hopes of having the proper base timing, but still this is far from complete. So im looking for someone that has a good base tune timing map for Megasquirt, I have a stock engine with a 14b turbo/intercooler and all the associated parts, one range colder spark plugs, and virtually everything else stock. All the help i can get will be much appreciated.
