1997 S1 Wgnc34 Rs4 Ecu Harness?

[mowgs]

Hi All,

Quick (hopefully) question regarding the ecu harness for the Stagea.

Have an auto s1 rs4 and have been looking at piggybacks (mostly fcon) - I've found the pinout diagrams on t'interweb but just wanted a definitive answer on which harness, if any, will fit

From looking at the diagrams, will the r34 gtt harness fit? I can see that the gtst one is completely different. I would have expected the gtt one to be matched to the s2 stagea, but seems to be the same as s1 too?

I did search before posting but couldn't find a definite answer!

Ta!

I HAVE and am RUNNING an R34 GTT HKS piggy back loom , using an F-con iS !!

The HKS loom is a direct fit WITH MY ECU ! ( 3 / 4 types ! - I hear say it makes a difference ! )

As the loom only uses some wires ! , IT DOSE NOT EFFECT RUNNING of ancillaries ( air con etc ) .

I am still running auto box .

Yes the R33 has only two rows instead of 3. The GTT one may fit but double check the pinouts. The main thing I can think of is that the GTT may have traction control but if you're just using the harness you should be able to make it work. What is your ecu number? There were 3 different ones.

Earliest and most common is the OV300 followed by the OV301 and then the OV310.

Do you have someone who can tune the F-Con (you need the special software and licences)?

Forgot I should have asked you ted!

Will check ecu number

Yeah, there's a few that can tune the fcon here in the UK, the mapper that I've had the best feedback from so far suggested it.

That's good then, will gave a looksie during the week to double check.
