[QUOTE="UselessPickles, post: 670573, member: 3256"] The PCV + AutoTune and Motty AFR Tuner are roughly equivalent. They both perform the same main function (automatically tuning a fuel map based on and AFR target map). The main differences between the two are: [LIST][*]Motty is a single device with self-mapping, data logging, storage for 2 maps, and a custom switch/button can be easily added to switch between maps on the fly. To get all of that with the PCV, you also have to buy the AutoTune module (for self mapping) and this [URL="https://www.dynojet.co.uk/quickshifters/lcd.htm"]ugly LCD display[/URL] (for data logging and multiple map switching; it also has some potentially useful display features). [*]The PCV plugs into stock connectors on the bike; the Motty requires custom wiring (that was part of the fun for me). [*]Price is different if you forgo the data logging and multiple maps on the PCV. PCV ($279 at fuelmoto?) + AutoTune ($199) = $478. The LCD module is an additional $233 -> totals up to $711. The Motty is currently $683 (fluctuates with exchange rate; I got it for $630) + ~$50 for the wide band sensor (cheaper to buy it yourself than order from Motty, because they would have to import from the USA just to send it to you) = ~$733. The Motty is actually priced pretty well considering everything it includes. [/LIST] There's been no change in the ECU or injector wiring since 2006, so all Gen II FJRs should work just fine with the PCV. [/QUOTE]
