924S : The ECU is located under steering wheel (924S)
944 phase 2 : The ECU is located behind foot well passenger side
Open the ECU by bending the small metal tabs. Remove steel cover.
You see two circuit boards. The upper panel needs to be seperated from the lower. At the rear where the connector pins are you can pull with care to open the pins, This is a pin inside another pin, push open with thumb and finger. If opened, pull a little backwards and the circuit boards are opened. You can leave them attached with the flatcable.
This is your kit, 2x 2-pins and jumper wire for B700 and matched injectors
Extra pins to be soldered in place
All ECU 1987 and later do not need soldering as the eprom is already 28 pins. You can simply exchange. the eprom.
Removing the eprom is a delicate job. Use a very small flat screwdriver and gently lift the front and the backside evenly mm for mm to avoid any bending of the legs.
Extra feet to be soldered on the front. The holes are already in the circuit board.
Check the backside of soldering, use a magnifier
Jumper wire here.
yes here!
FQS is disfunctioned, you can set at zero or any other position
Remove the old performance connector (if attached) on the wiring loom, close to the DME connector. The combination with our Remap eprom will not work.
Install the REMAP chip with the small notch to the outside. Be very carfull and check that all legs will go into the corresponding small hole. You can use your fingernail to push them to correct position.
Only when all legs are good then slowly push down the eprom.
Now you can test with the connector attached inside the car. If the car starts and runs then the soldering is good. Now you can rebuild everything.
If it does not work, check the soldering and the position of the eprom.
You can also send the ECU to us so we can check for you and make the repair, charge will be 50 euro or maximum 100 euro if you really messed up.
