the mpguino NEEDS to be connected to the 12 volt battery so if there are any vss pulses or injector pulses it will still count them. If you EOC without an ignition kill switch then you might not get readings while the key is off, but only because the car stopped sending them. The readings should return when the key is turned back on.

My VSS gives a signal whenever turning with or without a car hooked to it.

My KEL injector based computer switches to gal per hr if it sees no VSS signal.

Problem is during EOC it turns off because the injection signal is what turns it on and keeps it on. Instead of sensing either signal. ithink, i better double check that.

Switching to GPH is an interesting idea...

Technically we typically tap into an ECU speed signal, my saturn has a hall sensor vss, but the ECU converts it to a 12 volt signal. The metro has a switch in the speedo.

I was thinking about if/what to do if vss pulses is 0 and injector isn't on the guino. A big part of me wants to set off a 200 decibel alarm if that situation persists for more than 10 seconds

I updated post 1 under the installation notes for some online sources of vss info. on rostra it lists your zx2 as 8000 (probably really 8208) pulses per mile and gives some details how to find it on the ecu plug.

I haven't heard of any. It will take a little extra sensor hardware. Diesel John has had some luck with an old flow meter: http://ecomodder.com/forum/showthrea...html#post10747
