The Ecu is screwed to the main chassis with 3 Phillips screws, remove these and set them aside. You can now move to a clean area for the Ecu strip down. Take care not to let any moisture or dirt enter the Loom plug left hanging in the scuttle. The Ecu and Ecu chassis can now be removed from the car. You will see a stainless steel tap holding the connector, this has to be lifted up and away from the tab on connector, as in the picture. You now need to unplug the Ecu from the main engine control loom. With the Ecu now free from the body it can be lifted up and out of the scuttle area. Once these are removed you can now give the Ecu a solid tap with your palm to dislodge it from its nylon clips. The rear one is awkward but you will get to it. In order to remove Ecu and chassis two 10mm plasic nuts have to be removed to the right side of the chassis. You will now see the Ignition amp and heatsink screwed to the Ecu chassis, and also the engine loom supply connector.ĭisconnect the Ignition amp connector, and remove the Loom connector from the Ecu chassis also.
Remove this cover to gain full access to Ecu and Ecu chassis.
#GTI ECU TUNING DRIVERS#
The Ecu is located on the drivers side underneath a cover at base of windscreen. My car has a Gs2H kent cam fitted also, along with G60 Injectors.įirst off disconnect battery, keep in mind any codes that could possibly be lost from things such as cd players etc. Ill be swapping in a Superchips brand chip just to see the differences in performance. The major difference being that the Digifant 1 setup has a vacuum pipe connected to the ecu which has to be disconnect at the time of removal also. This guide will also give you the basics if you want to change the chip on a G60 running Digifant 1. The car Im doing this on is a 92 8v Gti, running factory Digifant 2 management.
Its a pretty simple process and if you take your time you wont go wrong. This comes up a fair bit so I thought a guide would help things a bit.
