I am trying to wire up race technology DL1 data logger and requires pins out description of a 84 3.2 DME, could someone please point me in the right direction.

TIA

anyone?

Here's something I captured some time ago when I had my '84. I cannot vouch for its accuracy.

DME connections
-----------------------------------------------

1 coil ground (1)
2 micro switch (throttle, idle)
closure to ground at idle position

3 micro switch (throttle, wot + throttle valve) test connection b
closure to ground at wot

4 t54, starter active
+12 volts while cranking engine

5 gnd
6 gnd, air flow sensor, ntc I

7 air flow sensor +
8 speed sensor +
0.6 to 1.6 kohms between pins 8 and 27

9 air flow sensor -
10 plug for exhaust data (ground)
11 t54, speedo
12 test connection a
13 ntc II
1.4 to 3.6kohms at 70oF
160 to 210ohms at 212oF

14 t55, injector control signal
15 t55, injector control signal
16 gnd
17 gnd
18 +12v

19 gnd
20 control signal, dme relay
21 t54, goes to speedo
22 air flow temp sensor, ntc I +
23 .75ohm connection to pins 5, 25, 26, 8 & 27
24 oxygen sensor
25 ref mark sensor +
0.6 to 1.6 kohms between pins 25 and 26

26 ref mark sensor -
27 speed sensor -
28 altitude sensor
29 a/c compressor clutch 'on'
30
31
32
33 idle speed positioner +
34 idle speed positioner -
35 +12v


pinout, looking at the DME connector, NOT the DME... (pins 1 & 19 are supposed to be at far right of each row of pins)

thanks Mark,

what's t54, t55?

Also any idea where the TPS signal is? (throttle position sensor).

Mark Hald

I sort of thought that pins 2 & 3 were what tells the DME whether the throttle is WOT or closed. Other than that, I don't think there's a "TPS". I'm also not sure about "t54" & "t55". Chris Bennet is the DME expert.

Yes, the Porsche 3.2 & 964 don't have a TPS, but the 993 & later
Porsches do. The t54 & t55 are the 3.2 injector COMMON outputs.

How can you get RPM?
I'd like to hook up RPM and TPS to my Traqmate Data Logger.
