    RUDE fuel controller or RRFPR with Riva XX SC?

    Thinking about turning up the boost via a Riva XX SC and im wondering which is the better route for fueling using 50lb injectors. i like the idea of having the RUDE controller but setup and tuning is more time consuming and complicated as well as more things that could go wrong but i've always thought a RRFPR was a band aid way to go even thought they work so well. price point isn't a huge deal. Just getting bored with my dated S3 SC and a turbo kit which i would like is out of my budget even though i have access to garrett dealer pricing.

    Get the rude controller, you can dial in your af from top to bottom.

    Which way you go would depend on your setup. Having used both on mine, I prefer a rrfpr.

    I liked the Rude controller as it gave you full control without having to worry about a RRFPR not rising properly, the fuel pump giving up due to high pressure and damaging injectors coz of high pressure.

    It is more time consuming to work with and without a way of logging rpm, boost and AFRs its difficult to know where to make changes so you have to make more general changes in areas of the map to get the AFR correct based on RPM and Boost. That said you can make a very nice working map in a few hours of tuning.

    You may have seen a few people including me talk about using the RFC to only pull fuel out and use the injectors and RRFPR to set top end, this because in the un-likely event the RFC goes down the top end will always be safe coz the RFC wasnt doing anything anyway. That is how I set mine up using a Les Cooke 8800 ecu, 80s, RRFPR and the controler. It worked well but I wanted to push things abit further and plan on upping the CP of my motor with the 2Rude so wanted the full control of a standalone.

    Here are a couple of threads with tools for you to use and help you set up and understand your controller:

    I am all about keeping it simple and the controller seems great when your injectors are big enough on top. You are just taking fuel away everywhere else. If the controller fails you still have all the fuel up top and you will know it in plenty of time...(Sluggish in the middle and off idle would be the signs). All that said there are not many stories of them failing.
