Hello all,
I recently acquired an exceptionally low milage (3200 miles) Ariel Atom 2. It was a "stage 3" unit according to the manufacturer making 300 hp, lol not. So, after getting acclimated to the car, I started tearing it apart and "upgrading" some of the parts. Most notably, the entire fuel system (AN -6 fittings, E85 fuel lines, AEM E85 pump w/ PTFE submersible lines and an E85 sensor), dual pass upgrade, exhaust upgrade along with some suspension changes to make the Atom a bit more reliable on track. Since the OE ECU can't run flex fuel, I also opted for a full wire in stand alone system from Link (Fury ECU). I've got the system mostly wired in but I'm currently stuck trying to find a 5v reference to the pedal harness, ugh. As soon as this hurdle is complete, I'll take the Atom to get tuned and actually start enjoying it. Here's a couple pics of Captain Proton, my Atom.

UGH, Chevy 
... I found that on C1 harness (the harness to the blue plug of the OE PCM), the tan and black/white wires that are the 5v reference are NOT that color on my harness. Chevy must have run out of tan wire so they opted for pink. So, after testing EACH wire on that harness for ground, sorting the wires that weren't grounded to the chassis, checking them for continuity @ the pedal harness plug, I FOUND IT. So, spliced it to the 5v out on the Link, sync'ed the TPS & E-throttle and voila, it started. I still have a few issues to iron out like why there is no 12v out @ the IC pump harness and the end link swap but now I can see the end of the tunnel.
