Title: enabling additional input pins?
Post by: elRey on August 13, 2014, 12:30:21 PM

Hello all,

Is it possible to enable additional, unused 0-5v analog inputs? I know any filtering would require custom code, possible copied from an existing function.
But how would I enable the input pin and access the input value?

Thanks,
Rey

If you find the analogue pin code in your ecu it should be obvious.

iirc, you request the value from the AD converter register then assign it to a ram cell, then another routine can deal with it from there.

Have you successfully enabled additional pin?

Title: Re: enabling additional input pins?
Post by: elRey on September 08, 2014, 08:19:22 AM

I have. Not so much as enabling as identifying pin and memory location.

ecu pin 17,19, 100 are unused A/D inputs. on the AWP 1.8T ecu. Trying to identify other non-A/D input out puts.

Post by: terminator on September 08, 2014, 12:25:23 PM

Thats already good progress. And what for do you want to enable additional pin?

I think its useful for adding switch for maps selection.

Post by: elRey on September 08, 2014, 12:37:28 PM

I want a second MAP sensor input for a compound turbo setup.
Also want to add an OEM EGT sensor to monitor EGTs.

Then there's outputs for inline fuel pump I want on only when needed and to repurpose kombi valve solenoid for a boost actuated exhaust cutout valve.
