V Twin down on power

[chris72]

Hi
We have recently converted a suzuki TL1000 turbo to EMU and have an issue during tuning. The bike revs well in neutral and 1st gear after that it seems slow to rev and is down on power.
WEe have more dyno time booked for next month but could someone look at the log and the project in case we have missed anything obvious as the owner insists on running it on the track before the dyno.
Bike is running on 100% ethanol.

thanks

55 degrees of spark advance on a boosted engine!!!.... thats extremely high!! im surprised it hasnt damaged a piston

also its very rich you should be aiming for lambda 0.95 at least idling and light throttle, maybe 0.85 at 100 Kpa and graduating to around 0.75 at maybe 1 bar of boost and over

I have wondered about the timing, it is accurate while cranking and at idle however if we run less timing the engine makes even less power ? is it possible that the ignition timing is not correct at higher rpm ( 16-2 trigger)
As the bike runs on ethanol it should be relativley safe from detonation while the boost is still low i will make some changes to the fuel map as you recommend

many thanks

easy check: lock the timing to 0 then rev the engine up with a timing light, see if you still have 0 timing, pay to make a mark for each cylinder and check them both!

Thanks

i will get that checked, as soon as the engine is repaired it would appear that on this engine using ignition retard for launch control results in damage to the cam buckets. Any suggestions for a smoother launch control stratergy.
