    Rude controller and RIVA ecu

    When running the Riva ecu, which injectors can be run with Rude controller ? Is it ok to run the #50 injectors that come with the RUDE controller or do you have to run the RIVA 50 injectors. Is there a difference between the two #50 lb injectors ??

    You can use the 50 # injectors that come with the controller. Or just use the 50 # injectors from Jerry's store with the Riva ECU.

    You must use the 50# injectors with the Riva ECU. That is what this ECU is mapped for.

    You do not need a fuel controller with the Riva ECU, but if you do need more fuel delivery, such as with a turbo kit then you simply add the rising rate fuel pressure regulator.

    You can also use 55# injectors with the Riva ECU. You just have to use at least 50# injectors because with anything smaller you will run lean.

    In cooler weather, mid 60s and below, and situations when you would be on the rev limiter pretty hard you might be a tad lean with a Riva ECU, 50s, and the Rude S/C...especially with a 4" intake and gutted exhaust...Jerry has said you could swap the 50s for 55s in such situations and be fine...

    Even stock skis melt the manifold. When you use shitty cast aluminum as an exhaust manifold its going to erode.... PERIOD!!!!

    I run this exact setup up here in 50 degree temps. Rude/55's/Riva/etc...still pulls hard; albeit a tad rich down low.

    Steve has the fix for it at a good price, and my manifold does not has the stainless nipple yet, but over 90 hrs and I always avoid the rev-limit and no issues thus far. I run 84-8500rpm for 15-20min at a time, and do it more often than u could imagine. We ride/goof-off 20 mins. from where we launch, and we waste no time getting there My manifold looks good. It is my belief that riding on or too close to the limiter, causing a lean-out. To me, 20psi under the limit is safer than 10psi on the limiter
