chargecooler Options

[dan4]

right i have trawled for weeks now to find out how to get the st205 IC pump to run constantly. i know i could just put a live feed and earth to it and run it off a switch but its my understanding that its connected to the ecu and will therefore put the engine check light on. Someone please help me...!!!!!

oh and for a nice easy mod on the stock st205 chargecooler clean out with petrol or a very high quality de greaser and apply heat shielding to the underside and you will see charge temps drop dramatically.... i was seeing 50-55 deg centigrade at 1.1 bar of boost and a ambient temp of about 7degrees centigrade, i am now seeing 30-35 at the same boost pressure and same ambient temp and i am yet to finish the heat shielding properly. NOTE when you flush the chargecooler, if there was a fair amount of oil in there it will smoke heavily as the deposits gradually work their way out.

I was afraid of that. If you can measure the voltage of M+, M-, and MTT when the pump is running and when it is stopped with the stock wiring configuration, we can probably figure this out pretty easily. Hopefully it's a simple voltage output that we can interupt with a relay so that it thinks it's off when it's supposed to be.
