ipk help/information request

cb750chris · 19th December 2019, 17:57

Don't know if anyone can help?
Bought a replacement Ipk with a good display, however the fuel gauge isn't reading properly.
The dials work as expected when in test 2. However the gauge only reads 3/4, even though the tank is full. Test 6 shows 43 litres, which matches the needle position.
The old ipk is reading correctly, suggesting a fault in the new ipk, rather than the car.

I suspect either the a/d in the ipk, or the voltage reference. Doors anybody know where these chips are, what volts I should expect on them. Or any other suggestions?

Thanks
Chris

Hi I think you have to have a virginised eprom in your new IPK and then programme with T4.

I think someone with come along with more help.
