Does anybody have any contacts where I can get hold of a standard ECU for a EVO IV?

Obviously dont want to pay top dollar, so any tel. nos would be appreciated.

I spoke to Euan, (nice chap) who told me £750 for a new one, and he doesent have any second hand ones.

Having just bought a Evo V ecu for £100, I wont be ordering from him.

Unbeknown to me, the Evo V ecu does not work properly on the Evo IV as the injectors on the two cars are different, and when you turn the boost above 1 bar, the car starts to detonate.

Evo 4 - 510cc/min injectors
Evo 5,6 - 560 cc/min injectors.

Just a thought but you could try some evo 5 or 6 injectors with the 5 ecu.
or an Apex S'AFC to readjust the fuelling

Basically you need the 510's to be open 9.8% longer with the 5 ecu pulse widths.

Yes, good thinking, we could put the V injectors in or maybe the VI, just thinking of the cheapest option, as Im a tight git. ;)

We do have the S - AFC Apexi controller, but unfortunately DP were not able to adjust correctly.

SAFC should work OK - only problem is you will see fuel cut 10% earlier too!

Not a good solution on second thoughts. ooops!!
