So is this (TT-5) best with PV-4 or PV-2B
By IBSILLY
Answer QuestionThat's a great question - and it really comes down to your tuning competence and, what you're really after in terms of performance. If you're comfortable editing fuel maps on the side of the road or in the garage, without a computer, then the Dynojet Power Vision is going to offer you the most flexibility when it comes to getting your ECU set up to run best for your needs. Yes, the AutoTune function is very helpful, but even then it can sometimes use a tweak by the user to maximize performance. You won't be able to do that with the Dynojet Power Vision 4 Fuel Controller as the smartphone interface doesn't permit map editing. Both devices will allow you to download and flash exiting maps from Dynojet's library, but again, the Power Vision allows you to tweak those in an instant. Those are the chief differences between the two. If you're happy to flash over tunes and ride, then go with the PV-4, otherwise, I'd argue Power Vision is where it's at.
