Default UTEC Revision Summary

I'd like to start a thread (in fact I HAVE!) that enumerates all of the different UTEC board revisions and their differences.

Any information would be great. I have nothing to start with.

Post away -- please stay on topic and don't hypothesize.

RESULTS: See Pete@TurboXS's post a few posts down

Rev 4 - works on 2002 WRX, 8 dip switches

Rev 5 - works on 2002-2003 WRX, 2 switches (FC disable, Reflash)
Changes were made to the UTEC for the new fuel tank pressure sensor and polarity changes of some other sensors.

Rev 6 - works on 2002-2004 (and 2005?) WRX, 2 switches (FC disable, Reflash)

I think there is a Revision 6b as well..
I don't know anything about the earlier versions.

Is the Rev6 the only one that will run a JDM ecu and not throw an injector CEL?

They seem about right (which is why I quoted them in my post) but I'm not 100% sure. Nathan is probably the best guy to confirm them.

Hi Pete. I just received my USA STI UTEC and noticed 3 toggle switches. The manual refers to only 2 switches. Can you clarify for me what each of these 3 switches are? Is this a different/latest revision?

Thanks,
Abe

The latest USA STi UTEC does have 3 toggle switches. There are two processors fitted to this board so the extra toggle switch allows you to reflash the second processor. We'll amend the manual with the additional information soon.

So which switches should be used for FCD & Flash (first processor)? 1st & 2nd, 2nd & 3rd, or 1st & 3rd? And which position should the switch (2nd processor) be in -- default position? Also, can you send me the ammended STI UTEC Manual (PDF) to silverraddo@yahoo.com when ready? Thanks.

Regards,
Abe

There is a supplement that should have been included in your UTEC box. I'll send one to you on Monday via email. If you don't hear from me shoot an email to Nathan@turboxs.com

When did the second processor got introduced in the STI UTEC. Is it still considered Revision 2 or Revision something else since it includes new hardware. Or Revision means software only?

Also I echo the question above what is(could be) the second processor used for? Is it like the solenoid for water/alky injection? Anything else?

Cheers

Nick

So does that mean the revision 4 can't be reflashed? Are there any important revisions since then?
