V4 ESL options
Hi, i'm going to be fitting an ESL board to the ECU on my car but ideally looking to retain my original should i wish to revert to back to standard - car is a 1998 V4 sti
I know both the 6S (V3 sti) and 75 (V4 sti) ECU's are 3 plug - so here's my question -
If i cannot source a 75 ECU would a 6S do as it will be getting mapped with the ESL board fitted anyway?
Thanks in advance for any help given

I emailed ESL recently with this very question.
The 75 and 6S ECU are essentially the same ECU. Same plugs / pin layouts etc. Identical hardware I believe.
Only difference is the 6S is mapped for a vf23, the 75 for a vf24.
So yes, you can use either ECU (as it will need to be mapped for the ESL regardless).

6s = v3 sti
75 = v4 sti
These two JDM ECUs are physically identical, only difference is the base maps. All pins and plugs are the same.
8s = uk Turbo 2000 ECU
This is different to the 6s/75, cam / crank / pump sensors need swapping etc.

I just listed the ones I've owned,I was thinking my Terzo was V3 but it was V4 so the 1S and 6S are both JDM V3 and the 8S is UK V4 (not sure on the UK V3)
both V3&4 have the same plugs tho,apart from a few pin locations from JDM to UK.
Andy Stevens had the full list of classic ecus on eBay but don't think he sells on there anymore.

Thanks for all the replies - sourced a 6S so it'll save swapping pins on the loom - won't be fitted until it's on the dyno to be mapped so all good.
Thanks again all the input was helpful

0.5 bar is standard actuator pressure , before fiddling with the Map or switching maps ( that's even if there are 2 maps that differ to each other etc ) check the Restrictor pill is in place

update
esl chip is an old version (no wswitchable map)
Duncan and the guys at surrey rolling road had a look and rest the boost controller and its a health 298bhp boosting now at 1.4bar
been told that good for a 20year old V2
so what's the next step
new up to date ESL chip and remap again but with TD05 top entry will I get much more out of it
