Hi, I have a Moto Sports Auto Turbo Timer on my import WRX. Cant seem to make it work, it has worked twice, I dont know why??? I have tried a few different ways to set it and it just seems pot luck..........
It seems to have a Auto and manual setting. Just tried a couple of different settings, switched off and did not work, just showed .P. on display.
Can anyone help.
Thanks

Mine didn't kick in until the engine had been running for more than 10 mins.

Imho, your better off without it anyway. They do your engine/turbo no good what so ever!
