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?

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.

as i know it the r&d you can only add..and it is only low mid high ..the rude..you can tune buy every 500 rpm ..and you can add or subtract fuel

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.

I leave in Kavala Greece and believe me there is no enginering here to now anything about jet skis.My AFR at the 5000rpm is about 14,2 and at the full throtlle is 13,2.What is the FP? The RRFPR is set to 60psi.
