I've got a MY95 V2 '555' STI with a Polar Performance chipped ecu. Is there any way in which I could wire it up to switch between maps?

I understand there is a wire that is cut for the new chip to increase the factory settings, could this be linked to a switch, and could it be changed on the move??

Thanks for any help

yes it can be linked to switch as for changing on the move i don't know, when i had mine on a switch i only changed it with the engine off.

On the bottom of the ecu you will see a resistor that will have been cut or unsoldered, I think its called "J1". Connect a wire to the end of this and run through a switch back to were the resistor was connected on the circuit board. I have done this with mine I also switch mine while on the move and so far havent had any problems.

You can replace the J1 link with a switch but you cannot switch over on the move. You must be standstill and engine off.

Scott advised me not to switch it on the move...

I best stop doing it then, is it and engine off job or just stationary?

He said best to be engine off but he thought it 'should' be okay stationary.
