Does anyone know how to modify the APC box and the APC valve ?

Any information will be much appreciated and tried :cheesy:

I looked at doing this a while ago and found that it was only possible to do it with the resistors if you had the old APC. The ones in the 9000 could not be altered in that way.

As far as I can tell the only way is to change the APC chip, which can be supplied by swedish dynamics.

I may be wrong

My 9000 is a 1990. It was DI/APC

The 93 onwards were Trionic as far as I know, so don't have APC
The Trionic does have a APC valve it is controlled by the ECU & the MAP sensor not like the earlier models which are controlled by a APC ECU & Knock sensor.
