Ok,
So went on the rollers again,this time we trialed taking the cam output on the ecu and paralleling it with a digital input,so now when the cam activates the ecu advances the fuel/ignition 10 degrees either way,so far this seems to be working much better than before.
We also got the narrow band running again which works ok but you can feel the ecu trimming under cruise might have to work on that a bit more later.
Also did some fine tuning to startup as it used to puff a small cloud of black on startup,i didnt get a clear answer from the tuners but im pretty sure having the ign/fuel change 10 degrees based on cam has helped significantly with how much of the fuel is actually making it into the chamber at low rpm's.
Did a three hour trip yesturday and didnt see any black smoke,however we did see a nice cloud of blue after a long low load run then full power from a stand still...and with fuel in the oil the only thing that can be is rings,not sure why i cant get this engine to seal,tuners are adamant the mixtures were not rich enough to cause damage....i dunno,i give up^^.
