V7 sti ecu in a v6

[RallyTechNZ]

Just wondering if anyone has done it?? My cousin (who is an auto electrician) said he use to do it with the old evos and was just changing a couple of wires around. Just looking into it for tuning purposes. If anyone knows it would be great to hear some info. Thanks

First issue you run into there is that the ECU v6 to v7 goes from a 3 plug to a 5 plug. You'd either have to rewire the plugs to the new v7 plugs or make a v5/6-v7 plug adaptor harness the ECU's change a fair bit.

Though the v5/6 ones are tunable; I hear STM has the gear to tune them now. And there's the place near Napier/Hastings or that area.

Yes i contacted them and said they can tune it but dont recommend to and probably wouldnt do it

Few things that could cause issues: avcs would need turning off or run a wrx non avcs ecu, cam/crank triggers are way different and would need swapping over, will need a fair chunk of wiring swapping over and the headache of recalibrating everything. Its been investigated a few times on here and burntrubber I think his user was/local up here was going to try setting it up in his V5 unsure how he got on. Personally if I was in your shoes Id just rip into wrc developments and see what he can do with it. Hopefully ecutek can do away with the maf.

the development of V5/V6 ESL board is still in progress and due to be released Early Next year.

this option is a better(cheaper) than Ecu tek.

We(SSM) are also Official Distributors for ESL Daughterboards in NZ.

There is another option the French one name escapes me but I got him to sign up here theres a thread on it. Only issue with it is theres no distributor here and ecus have to get sent over there. Hopefully someone picks it up over here.

I was looking in to doing the swap in my forester.

Basically, change crank trigger wheel

change cam sensor wheel

change maf sensor

there were a few more sensors to swap for the v7 ones

Easiest to do the swap if you got a engine and body loom and repin for your dash,or swap in the v7 dash.

A small weekend job it certainly isnt, But the advantage is tunability in a v6. If you arent patient, or good with electrical drawings, you are much better off getting a link
