and is a turbo timer really needed anyway? think of when you pull up to stop you are normally slowing down anyway so that give the turbo time to cool down. Look at most truck companies who used to have them; the have all taken them off and found they saved with one company just over 1million dollars by just idling slowly then turning the engine off rather than let the turbo timer run.
We can also looked what happened to Booya (magna) his car caught fire but the engine didnt turn off straight away as the turbo timer was on and kept the fuel pump working and putting more fuel on the fire
I used to have one now i dont bother i just idle my car slowly for the last k or so b4 i stop
