I know this is probably a long shot, but would anyone happen to know the factory ignition dwell times for the diamond or even hitachi coil pack?

Also, I'm looking for the injector injection timing.

I need a stock car and an oscilliscope...

Oh that's a good question. The dwell time has gotta be somewhere around 2 ms but I don't know exactly.

Got some info from Fineline Imports on settings they use for the Impreza with the same coil setup.

Code: Select all

6v  7v  8v  9v  10v  11v  12v  13v  14v  15v
10  10  8   7    4    3    3    3    3    3 ms

The injector injection timing they use is 400 deg BTDC

Also, I got the injector deadtimes for the STi yellow side feed injectors.

Code: Select all

  6v    9v   12v    14v     16v
7.66  2.69  1.37   1.06    0.75  ms

I need to ask them about my gray Diamond COP's before I get her going.

How far off were the deadtimes?

Not too bad at normal voltages, but off quite a bit at lower voltages.

Code: Select all

Voltage     Deadtimes (ms)
6                3.490
7                2.810
8                2.273
9                1.864
10               1.563
11               1.360
12               1.209
13               1.101
14               1.000
15               0.940
