hey has anyone here removed the charge cooler off a st205 (3s-gte)for a fmic if so how do u bypass the ecu fault code to stop it cutting to safe home mode can u trick the ecu into thanking the charge cooler is still there

If you have a basic understanding of wiring schematics that should be pretty easy to figure out. Basically there's a relay triggered by the INT signal of the ECU to send a signal to the M+, M-, and MTT pins of the ECU through a pair of 1k resistors. E represents the ECU's ground. Let me know if you need more help, I came up with this a year or two ago and it's been confirmed working by Urbandork and someone else on alltrac.net but I can't remember their name.

Since you already have everything there in your car, you can just replace the pump itself with a 1/2 watt or 1 watt 1k ohm resistor. The other parts shown in the schematic above are already in place in your car...

Actually you'll need a pair of 1k resistors wired like this:



I always assume it's a swap... I forget people are actually lucky enough to own a real ST205... jealous.

ur a life saver thank u so much
