Older Direct Fire Ignition System Settings
Posted: Sun May 07, 2017 11:10 am
There was a working Direct Fire Ignition System from Pacific Motorsports (Electromotive Coils) on our 2.0 Type 4 with 8.5:1 and stock feeling cam.
The device's timing settings are set in degrees as follows:
@ idle 12 BTDC
@3000 rpm 17 BTDC
@8000 rpm 0 BTDC
Once warm it idles high @ 1400 rpm so I will reduce down to 10 BTDC to see how that effect idle.
It runs well with these settings but does feel like there is power left on the table. I was thinking of advancing timing at 3000 rpm and know with a distributor 30 degrees advance at 3500 is ok. What are your thoughts with this device ?
Setting at 8000 rpm I'm not sure about as the over-rev function is set at 6250 rpm
