I've seen a few throttle controller options on the market (TOM'S, A'PEXi, Pedal Commander, Sprint Booster) but it seems like all of them use colors to differentiate between modes. I'm colorblind and would very much prefer something with a digital readout, like numbers or letters, to be able to tell me what mode i'm in. Anyone have a similar problem? Pedal Commander looks like it has separate lights for separate modes, which might be a good option, but i haven't read a lot about GS F owners using it.

 

Not sure if it will answer your questions, but you reminded me there is a massive Pedal Commander thread on the RCF group.
Hopefully it helps:

Thank you! this is helpful.

 

hi, i have the sprint booster and it amazing. the controller is very easy to use and very small in size. one press is sport mode and there is a number showing 1-9 and another press is the race mode and there is a number showing 1-9, therefore it is easy to use and read even if you are color blind blind. other modes are indicated by letters like valet mode and such. the race mode is bonkers on our cars if it is on the 8 or 9 numbers. I have have on sport mode 9 to keep the car tame during street driving, but the response is improved tremendously and it is like picking up more torque on low rpms.
check out their web site you won't be disappointed.

 

Thanks so much for this, numbers could work well for me! i heard that the A'PEXi has a pretty large module you have to hide, and has had some reliability issues. None with the sprint booster?

 

so far no issues what so ever with the sprint booster, and it works flawlessly. you will not be disappointed. i think it is the best throttle controller out there. i did my research before buying it, and it was exactly what i hoped for.
