I had the "race" ecu fitted with my RG3s on my 1000R
definetly a step up in the power stakes, but that is just my ass dyno - not run the thing on the dyno as yet
bike does fuel better, but still a bit "snatchy" at low revs
going to sort this with eother a PC or X81's new ecu
had the ecu on bike a year, & had no overheating issues, although i am paranoid about it as the bike boiled over on time when I was in France, when the fan relay packed up - nothing to do with the ecu causing the bike to run hotter
in fact i think the bike runs a couple of deg cooler (maybe due to slightly richer fuelling???)
not the perfect solution methinks, but a step up
