There's not that much to it really...
Buy det cans and a WB02.
Retard timing using the dizzy to 8 degree's BTDC at idle with vacuum hose to ECU disconnected and blocked then reconnect.
Increase fuel pressure on EMFPA by 1/8th of a turn clockwise.
Increase boost by a few psi.
Do a power run monitoring for det and lean AFR's (above 11.8:1 if going for a bar plus of boost, can be a bit leaner if not), abort run in either case.
Make adjustments based on the run, if lean increase fuel pressure again, if det is heard retard timing (unlikely when starting at 8 DBTDC).
Increase boost and run again.
Rinse and repeat until you are at your desired boost level based on a million other variables about your cars spec!
lol
Then gradually advance the timing again to the point of det (monitoring and adjusting AFR's), back off a few degrees.
Set idle AFR using idle mixture screw.
Done.
Make sure if you set it up on 99RON you always run it on 99RON.... or you'll det.
