    Programmable ECU-RXT-X question

    I'm thinking of doing some major upgrades to my 08 RXT-X in the future. What is out there for programmable ECU's and what's going to work the best in a turbo charged application??

    I've found two; this one http://seadoocentre.com/new_electronics.htm

    And this one; http://www.4-tecperformance.com/inde...roducts_id=285

    Which is better, and why?

    the Autronic SM4 is by far better for a turbo setup , because of functions, such as antilag , elektronic boost control, oil-temperatur control, etc.

    the IGNI power is more easy to setup, but if you buy the Autronic SM4 from a real dealer you get full support, and a perfekt mapping for your setup.

    I have tested both application on a turbo setup, and the performance is night and day. even you can get the turbo running fine with the IGNI power, the performance is better with the Autronic ( im using the AUTRONIC SM4 and the R500 AUTRONIC direct fire CDI with custom wire harness )

    i run both systems with 1.36 bar (20psi) boost at 9300 RPM Limiter

    we sell the Autronic SM4 with a custom turbo mapping for 3900,- USD, ( you need to have some specifikation on your turbo engine build, comression, open loop , etc )

    so if in theory you built a turbod ski you could email you the spec of engine,turbo etc.and tell you what boost your after and in theory yu can add a suitable map on the sm4?then its just add ecu to the ski and itd be safe to go wot?or would you still need rrfpr?

    you dont need a fpr, because the Autronic runs 83 lb Injector mapping.
