Placement for dyno rpm pickup
Hi guys
I dynoed my car yesterday. We placed the pickup for RPM on the wires going to the coil (as usual) but for some reason it would not pick up. Think there maybe something wrong with the pickup. Is there a better place to put that pick up or do I have to run a HT lead from the coil pack to the plug and go around that?

2 ways...
Method A:
1)Attach dyno pickup to loop wire.
Method B:
1)Remove No. 1 ignition coil.
2)Connect No. 1 ignition coil and No. 1 spark plug with suitable high-tension wire(spark plug/coil wire will work), and attach dyno pickup to this wire.
I'd choose A, since it's easier. I looked at my 5th gen and this "loop" wire is pretty easy to find. It's located above the EGR tube on the drivers' side of cylinder bank one that runs to the intake BEFORE the throttle body. There is a LARGE harness bundle that runs over the enngine between the two banks. The "loop" wire is just sticking out of this harness in about a 2-3" loop. You can tell that it was purposely left out so you can get in inductive pickup around it.
Sorry no digicam, but I can fax you the crappy ESM diagram tomorrow at work.
