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.

Splice into the blue wire on the 26 pin ECU connector (when lookin at the back of the connector it's the 5th from the left on the bottom row) and run a wire to ground. That should allow the ECU to think it's functioning normaly. However, I couldn't find out what the function of the M+, M-, or MTT wires were. If they are there to sense that the pump is running when it shouldn't, then it will probably throw a code. If that is the case, we'll have to come up with something else. It could be as simple as one or two relays.
