Rightio. Bit of an update.
At 19 PSI (boost controller turned off) it's best run was 417 rwkw at 7400 RPM . That stupid missfire is still there. A few theories floating around at the moment. A dud valve spring or injectors (although AFR's are holding true even when its doing its silly noise). Yavuz did make the comment of "there is so much left in this".
We turned the controller on to do a few tests. 26 PSI was all in by 4300 RPM. I did see 375 rwkw by 5000 RPM (at 23 PSI I think) which is pretty close to my goal of 400rwkw by 5K! Yavuz did say we are looking at 440-450 rwkw. Considering cams have not been touched yet, it's looking promising.
Also. I switched across to an ECU called "Blackbox". Unigroup run this in their Racecar. Its been made into a plug-in version for our cars. I only ditched the link because I ran out of input's on the Link. Ethanol Content sensor's, Oil pressure, fuel pressure, wideband blah blah. Yavuz made me jump in the seat and have a play with the throttle. It's so bloody touchy! I noticed this change going from Power FC to the Link, but it's that again.
