what is the difference between the md159966 ecu and the md159964? I have a blown 9966 in my stealth and the 9964 seems to be much more plentiful.

159966 is for a TT car manufactured between April 1990 and May of 1992. I can't find a listing for 159964, but 159962 & 159963 are both for NA cars from the same dates. I'd have to guess that 159964 is also for an NA.
The 159964 doesn't show up on the US list. It appears to be for a TT GTO, which is not a USA model.Quote:

Most of the listings I saw with a quick google are from Canada and New Zealand.
Sorry, I have no idea if it will work for you. Try searching for "J-Spec ECU", maybe that'll turn something up. You could also try the GTO forum, those guys might know more about it.

Good luck!
if it does turn out to be a same-year TT-ecu, i'd use it. afaik, the only difference between JDM and USDM spec is the provision for more 02 sensors on the USDM models.
so yes, as cliche as it sounds, JDM > USDM
yeah, emissions controls being what they are a JDM will produce a few more valuable horsepower. I was just wondering compatibility, but if its this confusing I think I will pass on using it...

You do not have to install the exact same ECU part number in your car BUT you do have to install a new ECU
with the same E2T number!
Pull out the ECU and under the part number on the label there will be a number starting with E2T.
Those numbers on your original ECU have to match your new ECU.
notice that 9964 isn't on the list. there's only 2 listings for JDM ecu #'s on that page. i'm fairly certain that i have a JDM spec ECU in my car because of the wiring issues we encountered when switching from the N/A ecu--but i don't have a clue as to which one i actually got. it was sold to me as a rebuilt 9966 by auto zone.
