HI recently purchased a fuel x pro, have a slip on exhaust as well. I’m new to mapping but want to learn. What are some basics need to know things when selecting the maps to use after installing the fuel x pro? Kind of a “ mapping for dummies “ ? Any help or guidance is appreciated! Here’s a pic of my 2022 390!

Mapping for Dummies stage 1. Take it to an expert dyno operator to get it setup.

Stage 2 learn everything you can about mapping and buy all the tools before starting to fiddle with your bike.

With just a slip on I’d suggest leaving it on setting 3.

Is it really necessary to have it dyno tested? The advertisement for the product insists it’s a mappable “ plug and play “ device. Making it seem almost effortless to get exactly what you need without having to be an expert. From what I understand the higher the map number the richer the bike will run and lower the leaner. If the stock setting is 3 with no mods, wouldn’t it be safe to assume with a slip on ( soon will have a decat mid pipe and new air filter ) that maybe 5-6 would be optimal?

Race Dynamics make two versions. The Lite is the plug and play autotune version that will give the correct fuelling for all mods. The pro like the rest of their line up is designed for the racing community to give riders quick adjustments to the built maps. In the RD engineers own words choosing which setting to use on the Pro is a question of trial and error. Yes, it’s plug and play and easy to adjust but there are two versions for a reason.

So how do you know when you are in error? You can either run by seat of the pants or you can measure it. You could copy the setting someone else is using but that assumes that everything else is the same and goes against the logic of why RD designed it this way in the first place.

If you are interested in learning tuning there are plenty of threads on here about it including the various devices needed to measure what’s going on. You will also see amateurs who believe they are experts arguing with each other, which is something you should think about before believing what you read on forums (including from me)

I’ve blown engines up and rebuilt them and my experience is that dyno time is a lot cheaper than buying engine parts. I paid £100 recently to a highly reputable dyno for a quick checkup and that included swapping jets about because VTwins are a pain to balance out - flicking the switch on a Pro on a 390 would have been cheaper and guaranteed to be right.

Nice lookin bike!

Bunch of info about the FX Pro I documented in this thread, I have settled on maps 4 or 5 most of the time on my bike (MY being the key word), but everyone & everyone's bike is different so you have to find what works for you.....

Thanks for the feedback! RD racing did respond last night and said I could run on maps between 5-8, anything above 8 should only be used on the track. Curious what I’m looking for when finding a “ sweet spot “ on those maps? I’ll start at map 4, and work my way up. ( I try to get RD racing to send me the lite instead of pro but they insisted if I do that I will pay a fee for restocking and some other shipping fees so might as well just stick with the pro, so I’m stuck with learning now ) thanks!

I tried to swap for the lite and was told it recommended to use the pro, and RD racing said to use maps 5-8

I thought they wanted a restocking fee? They are not maps, they are increments to how much richer it will make the stock map. That gives you a starting point but you’ll still need a way of knowing which one of those four will be right. Running too lean gives the most power so be wary of choosing based on which produces the most power.

They do want a restocking fee plus some other fees for shipping or something along those lines basically saying after all is said and done with the fees I won’t be far off from paying the price of the pro so I might as well stick with it.
