    Is The Rude Safe With The RIVA ECU?

    Is there a definite answer to this question?

    KiiwiRXP---YES-it is safe. The Riva Pro ECU is boost sensitive. I have been running this combo--- (Riva Pro ECU, Rude SC, and 50 lb injectors)--since last April and no problems. Works great.

    I run Rotax Racing ECU, Rude,#50's and NO fuel controller. I removed the FC and went from 82.5 to 83.3

    That is a good point about the fuel controller, my B-KIT is to rich with the 50`s I run 10.8-10.9 at WOT on the stock ECU I wonder what my numbers would look like if I removed the controller

    I think the correct answer to this question is borderline in warm weather, dangerous in cool weather. I run around a 12.6 a/f in hot weather. Seems a little lean for a forced induction motor, I probably wouldn't run my car this lean. I can only assume that number will get higher as it cools off.

    I think he is talking about the exh. manifold outlet burning on S3s that are run slightly lean at wot for a mile or so, I have no issues w/ this at all, and the stainless fix seems to work for those who need it. Add it to the list and get on w/ life if u think u need it.
