Ana2 is an input and aux2 is an output.

Thanks very much for all your help guys - had the engine on the dyno this week to map it. Everything worked first time :D. Made 490 hp and 450 ftlb - very happy!

It's hard to go wrong with an LS !

It's a light car, get some decent tyres on it and it'll be fine.

I'm redoing some of my loom which includes the log switch via ana2. For the life of me I can't remember if I used the 5V/pull up resistor as per wiring diagram or if I just grounded ana2 input to activate... :oops:
Anybody know which one works 100% I'm in the middle of this right now so any help would be appreciated!

100% works with 5v pull up, probably hit and miss without. If you have a wheel speed sensor you can select log to operate when wheel is turning.

The same switch does logging/wideband/map2 selection if I recall correctly ?

I just switched mine to ground, same as TCS, WET/DRY. Never had any problems.

ana input doesn't have built in 5v, others do

Thanks guys, I'll do the pull-up version now to save the (possible) headaches later. Looks like I need to source the damn little resistor now...
Cheers!
