Pin 31 on LH 2.4.x

Inlägg av Mathy »

Hello guys

BTW Nice idea, this English Forum!

First question: Some versions of the LH 2.4 (2.4.1, 2.4.2, etc.) have this signal on pin 31 that tells us how much fuel the engine is consuming. I thought all versions have this signal, but apparently they don't. Can somebody please tell me which versions do have a "fuel consumption" signal on pin 31?

Sincerely

Hi!

Unfortunately I don't have any answer for your question :(

I tried to search for more info with no result,

The only thing I found was this thread on another forum
https://www.flashback.org/t733065
Created by a member from this forum (Turbo-Mupp)

He asks if the computer from Volvo 400-series can be used, no answer to that. Another user links this thread
http://www.volvoforums.org.uk/showthread.php?p=318485
with actual pictures on a 700-series computer.

Hi!

There's some guys over at turbobricks.com that put a lot of effort into decoding the LH2.4

Here's a webpage they put up regarding it:

Hello guys

I've seen the pictures of the 700 and of the 400 trip computer. I'm not looking for that. At the moment all I want to know is which versions of the 2.4.x have this consumption signal on pin 31.

The only thing i can tell from wiring diagrams of the 940 94,95 is that non-turbo vehicles use pin 31 to a "Solenoid, pulsed secondary air injector (PAIR)"
