hi guys I have managed to work through most of the issues I was having but there just seems to be one last thing and I'm really running out of ideas.
The engine seems mechanically sound. Starts idles and revs no problem. No smoke. No strange noises. So all seems good mechanically.
Initially I was having the same problem as @nicole_ code a11 engine overheating and it was hitting a limiter. Sorted that by upping the threshold to 95 degrees c in s manager and that now seems good. No more code 11.
The problem is the car bogs and won't Rev when driving anywhere between 3-5k. It's not limiting. S manager display shows that the limiter is off when the problem is happening. The best way to describe it is like the fuel is cutting out. So it revs up smoothly and then just stops revving and starts to bog and struggle. Sometimes at 3/3.5/4/4.5/5k. feathering the throttle seems to get it through a little but it's not right. The wiseband gauge shows its rich very rich 10.8/11:1 but when it starts to bog the fuel jumps between the two extremes on the gauge v rich to v lean quickly. Like the fuel is cutting out. Ignition is anywhere between 30 - 19 degrees advanced. Lower the revs when the issue occurs the further advanced it is. Sometimes it will bang when it starts sometimes it doesn't. More often than not it doesn't which makes me think fuel?
It's a freshly built engine so I'm not looking to thrash it but I need it to Rev properly. I've tried three different calibrations and if seems to happen on all of them so I'm starting to think it's a physical fault with something? Dizzy/coil maybe? Going to try another one later. But no fault codes.
Had anyone come across this or something like it before? I'm really close to getting it all done. Just need to work this out and we are just about there... As always any advise or input is much appreciated.
