Hi
I am after a square type TPS Connector and the square Injector connectors off mk1a please. It will help me to test how the ecu's run with the other componants and whether adding more resistance to solenoid resistor makes car run differently to using High impedance injectors via EManage ultimate. (which requires higher impedance injectors
I am looking into what bits run with what so that if someone has a non runner then the part numbers can be matched up easily, or also for anyone who wants to mod their cars setup. They will know what they will need to do so that the fuelling can be modified without ecu failure etc.
I would like to get this info (below) accurate and make it a sticky on the site so it can be used by others... I have concluded the following from research on this site and others around the net
It seems that there are 3 ECU's and 3 types of injector for our UK cars
89661-17030 Nov 1984 to Aug 1986 injectors are grey and high impedance 13.8 Ohms - need to research config of this but if you run an early ecu on a later car then fuses blow apparently!
89661-17070 Aug 1986 to Aug 1987 injectors are Red but square connector and high impedance 2.3 Ohms wired in parallel with a 2-3 Ohm resistor pack = 4.15 Ohms load per channel on ECU
89661-17140 Aug 1987 to Dec 1989 injectors are pink with rounded connector and low impedance 2.3 Ohms wired in parallel with a 2-3 Ohm resistor pack = 4.15 Ohms load per channel on ECU
TO go with the ECU's above there are 3 x TPS for the UK car
Throttle position sensors:
89452-28010 AISIN - Nov 1984 to Aug 1986 (square plug connector)
89452-20070 Denso - Aug 1986 to Aug 1987 (square plug connector)
89452-12040 Denso - Aug 1987 to Dec 1989 (round plug connector)
Can anyone confirm this info is correct ?
