MPGuino usec/gal Civic CX/VX difference?

I have a Civic CX and was wondering if the usec/gal for my MPGuino will be the same as what it says on the wiki page for a VX (0279235000). Also, if anyone knows a better place in the CX other than the DLC connector for a 12V and ground please let me know. Thanks!

My DX is different than VX. I think it's 225000000, with a 100 Inj Delay (instead of 500).

Grab your GND and 12v from your (3-pin?) clock connector. Your CX wasn't sold with a clock, but the wires are there behind the dash. If you do have a clock, go ahead and splice into them anyway.

Thanks. My MPGuino is out for delivery now... If anyone has their CX numbers please post them! I'm planning on using cat6 cable to keep all the wiring neat and in one enclosure. I'm not sure if running the 2 wires from the ecu, and then 2 from the clock would work... Any input is appreciated.

I ran the ground to the ECU when I put mine in. I used this:
OBD1 Honda ECU pinouts - Honda Forum : Honda and Acura Car Forums

to find the right spots for my wires. I just picked one of the sensor grounds D21 or D22 iirc. For juice I put a voltmeter to test a couple of empty spots from the fuse panel. I found a good one and used it. There may be a good source in the ECU, but I ran out of patience testing different spots.
