13B rotary sand rail at little sahara utah

I decided it would be better to drive the sand rail back to the trailer, rather than tow it back from miles out. it was running very rough, but I was doing OK until the radiator decided to split. it is running a 13B rotary motor with a megasquirt II computer running the fuel, and spark..

put your foot in it man!

@szdevisser Trust me, I tried. most of the putting around was in the 3000-4000 RPM range, when I tried to lay into it, that is when it would cut out. I had to work the throttle to get it over 4000 RPMs, but once it was past that, it would just keep revving, and we never got out into the big dunes where it had room to run. Its running a megasquirt EFI controller, and it was way out of tune.

what was wrong with it

[kd7vea]

@midwestracer2003 I am running a Megasquirt II fuel injection controller. It had been running rough, but it would have made it, but I had NO brakes at all, and the throttle kept sticking. that was a bad combination. I have since fixed the brakes, and the throttle issue. the tune still isn't the best, at high load, my timing is still off, but it does run tons better. I will post some video of the last trip, the camera was mounted better, and it ran good.
