Want To Buy SX230HO / AR230HO MR-1 ECUs (6P6)

[Robb235]

I'm looking for the 6P6 ECUs to go along with my MR-1 swap project. Currently I'm using the jet ski 6B6 ECUs, which function fine, but I'd like to have the Check Engine Light and No-Wake mode functionality that the boat ECU provides. If you have one for sale, let me know. Would need to figure out some way of verifying that the ECU doesn't have the "stuck injector" problem that is common with them.

they are out there, I have a pair of each... curious about no wake mode... Im running 1800 rpm at idle and that turns out to be 4.6 mph and any faster than about 5 mph and im gonna throw a wake... I do notice that just bumping the throttle gets me 4000 on the tachs... i assume no wake mode cracks the bypass air valve and fattens the mixture for some specific RPM?

Yeah, I hesitated and lost out. Guy I was talking to sold them to you instead lol.

My GPS speedo indicates I'm moving around 3mph or so at idle. Can't remember off hand what my engines are idling at. 1,600? 1,800? Definitely less than 2k. I think my stock 20+ year old impellers may be contributing to idling at a slower speed than your larger boat. I'm also not hitting the top speeds I expected, again, probably due to the poor condition of my impellers. Then again, the XR1800 sits deeper in the water than the LS2000/AR210 boats, so maybe that's part of why I'm going slower at idle.

I mainly want the boat ECU so that I can get functionality of the warning lights on the speedo. I have the stock XR overheat warning lights wired directly to the themosensors in the exhaust, but I have no warning for if a check engine light or low oil pressure light comes on.
