Your ECU may not be retarding the timing on boost though, perhaps try another if you have one or can borrow one and is the vacuum hose connected to it too?
good morning,
at the beginning i also thought it was an issue of ECU that does not retard the timing but I tried 2 different ignition ECU (one without knock sensor) but nothing has changed. also i have tried to change the act sensor, metering unit, fuel ECU and fuel pump but nothing
.
i have already spent more than $ 500 in spare parts and equipment to control the AFR and timing. the only things that i have not changed are the dizzy and the camshaft.
