424 input

Post by Kevspec »

Is there any ways to have inputs to monitor anything on the 424 using 11p? Ie oil pressure and or temp?

I think I have figured out how to configure it all but I will just replace the knock sensor input for oil temp and can also do the same for pressure with another input

There are unused inputs, look at the pin listing in the 11p zip and look for inputs without a blank description and in the overview pdf, and the description of the fields in the log definition (adx) for ones which list the pin but not purpose. Note the coltage range. Knock is special, you cant use it for a different purpose. You can set enable temp to max to disable it and turn of cel for error to disabke it, though.

Yes the '424 computer was used in the VS V8 Auto. It applies where the '424 is used. https://pcmhacking.net/memcals.html

As for which pin, Ive got some bad news. I read the manual, and it lists only pin D8 as analog input for wideband for this PCM. You can still use it for whatever you want, but you loose wideband.

I guess the '424 was pushing the early platform as far as it could go and that's why they changed it to the next generation for the ecotec.

Sorry I know the 424 was used in both vr and vs but the diagram states vr is the pinouts the same for the vs? Yes I did see that for the wideband but I'm sure if I configure correctly I can replace what I am not using for what I want?

yeah if you look at the pinouts in the pdf that comes with it you can see whats a digital and whats an analog input, and see if you can configure something to make sure the logic behind what youre using triggers a failure, turn of set cel for that error, you could. Injector voltage monitor is there, we used that for wideband on the later ones. But I am not sure what repurposing it will do on 11p. VR/VS will be the same pins on the pcm.
