I'd run 94 as long as you can. If you have to run 91 at least have half a tank of 94 in there to help bring the octane rating up. I've always run my Mugen ECU on 93, and I've had no problems. Supposedly, in California some people had problems with it on 91.Azncowboy said:just a quick question, will the mugen ecu work with octane 91? we have octane 94 here in calgary, but when travelling some places may not have 94.
One of my cousins runs high octane on his bike and he say that the booster only works if you use the gas right then otherwise the octane filters out of the gas. at least that's what he understands of it. I trust his judgement, he has at least six dirt bike and is perhaps starting a business around bikes.Azncowboy said:cool cool, would octane booster help if a station only had 91 or 92?
Some people like the plug and play systems, myself included. Nice choice on the ECU, Im going that route as well!dc5 said:I still can't believe why people still buy Mugen ECU or any other piggy back system with K-Pro is out!But it's their $$$
