just had an idea, I just bought a set of Ford injectors, the special thing is that one of them has the magnetic sensor like the n#3 injector on tdi's.
with one of that installed, and a pickup somewhere to sense TDC, I could measure timing (time between TDC and start of injector lift/ RPM= degrees)
and also injection volume (start of injector lift - end of injector lift)
back to the real world...
mine behaves exactly as before the upgrade, same smoke level= same power as before.
so.. if it is cam float, if we swap just the cam back to the 2mm lift one, that problem should be solved right?
when you put the 9mm head back, have you also swapped the camplate back to the 2mm one?
