    R&D vs Rude

    What is the different between R&D Powershot fuel injection tunning module and fuel controller and the rude electronic fuel controller?

    The main difference is you can take fuel out and/or add fuel with the RUDE controller at 500 rpm intervals/boost. With the Powershot you can only add fuel.

    Usually guys are running rich with a RIVA ecu or stock ecu and need to pull fuel out low and mid range after adjusting their RRFPR for WOT AFRs.

    Sorry not getting that last part 13,2/1.

    Are you checking AFRs? Every LC ECU we have run lately has needed 80lb injectors to get good AFRs.

    Still don't know what your AFRs. And its next to impossible to tune someone else ski over the internet. If your WOT AFRs are 13+ and you FP is what? you may need more injector. Whats your idle and midrange AFRs right before boost kicks in? I and some others have tried to help guys thru here and it just doesn't work for the most part. Need to get the ski to someone who can help you near you.

    Your running to lean you need more fuel. Your afr at wot should be between 11.7 to 11.9. Adjust your fpr and see how u go.
