V7 sti ecu in a v6

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
