Nozzle spray angle...

New bypass valve is up and running...



Works great and seems to pass a bit more air than the old system, so I am
having to re-tune my VE map below 85kPa. Engine pulls hard all the way to
my 8000rpm redline with virtually no dropoff in acceleration. I am considering
getting a 65dia s/c pulley to replace the 75dia pulley I have at the moment.
This would mean dropping my redline to 7000rpm to avoid overspeeding the
s/c but I don't see this as a problem. It should help the engine live longer.

Currently I am chasing the misfire that I get when I accelerate hard in any
gear from around 2500rpm. It only happens once about a second after I hit
the throttle, and I have not noticed any misfiring further up the rpm range.

Bearing in mind the earlier comment made by rotrex about spray killing the
spark, I did wonder if that might be the problem. Hard acceleration at around
2500rpm invokes extra enrichment and also triggers the W/M spray. But when
I switched off the W/M spray the misfire still occured, so now I am adjusting
the enrichment tables to see if I can find an answer.
