Valve springs have really been a HOT issue lately.... had about 4 or 5 300rwkw plus capable cars with valve float...PL wrote:Hey Trent,
Yep, all good. I did that RB25 with 3076 just after Xmas based on your tune and I didn't have to do a lot to it:
- tweaked fuel map to richen mixtures in boost transition area
- turned off closed loop a bit earlier to allow richer mixtures earlier
- gave K constant a nudge from 180 to 193
- pulled a bunch of timing out at high load to allow 22psi boost
So all in all very little change reqd. Car made a disappointing 271rwkw but that's gotta be a mechanical/flow type of issue - the tune was fine. It retrospect I'd have rather left it on 18psi cos cranking in more boost really didn't do much....
