So I have MSII installed and now I find out (I'm a newb so forgive me, and my mechanic has not used Megasquirt before either so he is learning what it can and cant do etc....), after 6 months of rebuilding things and moreso troublefriggin'shooting we now find out we can't boost the 420a without a form of aftermarket spark control to retard timing?! I thought MS could retard timing but now that I hear about the special spark control chip you have to assemble and install yourself I'm all just .....frustrated...
anyways, WHAT FORM OF SPARK CONTROL BESIDES DOING THE TECH-SAVVY MS MOD CAN WE DO TO THE 420A ENGINE????

Obviously there are lots of boosted 420a's on this forum - how are you guys retarding timing?! It's just so frustrating cause i've put $10,000 in parts alone into this car and it still refuses to run without dumping more money into unforeseen cirucmstances... (and yes, I realize I spent WAY too mcuh on it but thats besides the point...it was originally gonna be $4000 in parts and then boostin'....)
