wonder if anyone can help...i did see a post ages ago somewhere where it had instructions on which pins to swap to change to a 130 spec (cult) ecu.

so what im stuck on is...i have a 1.8 silvertop from an escort si 115ps im running the standard loom from that car and the ecu with the key and transponder ect wired up.
i have changed to 2ltr silvertop cams and rs1800 throttle body. noticed and good improvement and all runs fine.
will changing the ecu make any further difference?
IF so will it be a case of finding the correct pins to swap and all will work? or is there more to it?

Any help will be much appreciated.
