stuck Posted August 11, 2011 Share Posted August 11, 2011 Gents, I note that on Hybrid From Hell's drwaing the MS ECU has several pins marked "Spare" Are any of these configurable inputs? I have an in truck PC running a 6" touch screen and was wondering if I could use the ECU & Megatune to display oil pressure (via a transducer obviously) Cheers, Mick.

FridgeFreezer Posted August 11, 2011 Share Posted August 11, 2011 The SPARE pins are just bought out to 4 contacts inside the unit on the PCB, they can be inputs or outputs but you need to connect them to something - the processor has various spare pins (JS_), some of which are analogue so could be used as a pressure sensor input. You'd need to build a signal conditioning circuit to make it work, although that can probably be copied from the existing temperature sensor(s) circuit. You'd also need to know the response curve of the sensor you're using. Lots of info is in the MegaManual / MSExtra documentation. Quote Link to comment Share on other sites More sharing options...

FridgeFreezer Posted August 11, 2011 Share Posted August 11, 2011 This piccy shows the positions of the SPR1-4 pins, as well as the (unused in MS-1) IAC pins (another 4 spares effectively), plus the main spare IO pins on the CPU (JS0, etc.): Quote Link to comment Share on other sites More sharing options...
