RS-2 TME

If you need to source parts (including Ralliart ECU) for LHD cars you can try Ralliart Spain. They ship worlwide. If you can't find their contact details let me know, or if you want a quote I can ask them and will post.

Another popular choice (at least in Europe) is the Power Engineering re-map. I am still runing the standard ECU and looking for an upgrade. I checked with them, and the price of the re-map is around $750 (you send your ECU they return it re-mapped).

I've contacted Ralliart already and luckily, they changed my order already to the SPORTS ECU since they are aware of the this LHD problem with the ECU. So I'm waiting for the right one after all. But hey, thanks for the advice.
