Well Ant at Kaizen sorted out my not revving issue. One 500hp walbro later and all is well.
BUT it has a misfire on idle and occasionally wants to stall after it warms up....
I've thought it may be getting too much fuel? Not because of the walbro, but because it has big injectors and a computer tuned in japan to run big injectors and a high output N/A motor.
I've got a stock ecu here, but the stock injectors don't fit my plugs? It is a JDM if that helps. Are the injector plugs different?
If anyone has any ideas, that woudl be tops!!
Thanks guys,
Nafe
misfire as in backfire? or a miss. I dont understand how it could stall after it warms up if it runs when cold.
to check, do you have cold start pluged in?
if the injectors are to big, that would mean its running rich yair? dose it blow smoke?
have you comp tested?
are you running advanced timing? either way the comp may be made to run it or not?
what ecu exactly?
85' JDM TA63 GTTR sedan - Godlike
89' JDM GZ20 Soarer - 1jz + R154 bus

On a more serious note, how much timing is on it at idle? How often is 'occasionally'?
Chuck it on a dyno if you want to check fueling but looking at spark plugs would be a good start.
As far as I know, jap injector plugs and aus injector plugs are different.
