does any one have this hooked up in there car. i should be getting mine this weekend and want to hook it up to maf voltage, knock, tps, afr, boost, rpm. about the only thing i know how to hook up on it is gonna be boost as it has the built in map sensor,afr and i know what wire senses knock. the others i am unsure of. what wires did you use to hook it up, and did you ground them all or just hook up the signal to the posative or negative to the lma3

Connections should be same, I used this setup when installing my Zietronix..

knock is KLR pin 15, but watch out, only the 5V spikes indicate knock, but they are super short in duration...

thanks, that should help. i understand pin 15 is a short signal, i just figured it would be able to show a knock, like the counters being used.

It will depend on the sampling rate of your setup... the Ziet takes 33 samples per second (33.3Hz) and doesn't catch all knock events...

Just be careful, and don't rely on the knock events to tell you, as it only takes one bad knock at a really bad time to wreck your motor...
