Alright...I bought a 123Tune. B20E w 45 HSR's, 10.5 :1, Schneider 274 Cam. oversize valves...etc, etc.

With 123 (normal version) it liked to idle at 15 BTDC...but I got worried about overall advance...so I bought (cuz I'm single with lots of petty cash) 123Tune
Current curve is 12 @ 800, 15 @ 1000(idle), 18@ 1500, 23@ 2000, 28 @ 2500, 32 @ 3000...rev limit @ 6200

Really lumpy idle, stutters to 1500, above 2000 smooth and much quieter than ever before. Running hotter than usual...Air Fuel bounces between 12.5 at idle and full throat 15.0

Am I using too many points? Should I start off at 15 BTDC?

Comments...? Other than "do I really know anything about engines...?" Well it's my TOY!

P.S. anyone seen John Parker? He's in one of his "I'm not answering" moods again...he owes me a set of roller rockers (for the toy)
