RE: New JetJoe J-Junior 4lbs turbine

I just used whatever the standard settings were in the ECU as I did not have time to optimise things..I have only managed three runs and I left the blower on until 90k and it carried on to idle (100k) after I took it off.
If your JJJwon't self sustain at that sort of RPM then there is most likelya combustion problem. One thing to try though, turn the gas off at 40k as this can blow the combustion around a bit and the ECU thinks it's supplying enough fuel when it's actually not so thiscould just be your problem.Other than that your engine is "knackered" and will be sitting next to mine on a bench in China very soon.
best of luck.
