Changed the spark plugs from bp7es to bpr7es and everything works perfectly.
never thought a resistor could make so much diference.

Thanks for the help

I do not have resistive plugs. Hopefully this is the problem.

I think your right about the electrical noise. My multimeter flashes random numbers from the passanger seat, even when its not connected to anything. I am using bosh leads that have between 5K and 9K resistance. (shortest to longest) Any reason for the EDIS system to be producing so much interferenc...

I am having problems writing to the ignition file while the engine is running. The configurator reports that the ignition file wrote but within a second the timing returns to its previous setting.( I can even here the engine speed change momentarily) If the engine is not running it writes fine. I do...

Finally got it working!
There is an updated driver for the PL-2303 on the Prolific website.

It was released in April so any body still having Vista problems should be able to get it working now.

I still cannot get the configurator software to work with vista. (it works fine on my XP desktop) There is no power in my garage so I need it on the laptop. It says it cannot open com port but the data log from my port sniffer says otherwise. Port opened by process "mjljConfig.exe" (PID: 5...

I cannot connect to my MJLJnr V4 using any of the vista machines we have. I have proved my build is correct using an XP machine with the same serial adapter as I am using on the vista machines. If I use a telnet application on the vista machines, I get comms with the 's' and 'c' commands, but the co...

I think I will try going to a breakers, so I can measure some sensors.
I can not extend the spindel shaft because it will fowl the float bowl. (but there is 13mm to play with)
I ruled out a MAP sensor because I have a 290 degree cam.

Has anybody seen a TPS fitted to an SU carb?
I have twin HS4 SU's and there is only 13mm between the throttle spindle and the float bowl.
I have considered fitting it to the accelerator pedal but there is only 30 degrees of rotation. Will that be enough?
I can not use a MAP sensor because of the cam.
