I Bought two planar dome C3I , i dont have graphic card.

ignition will trigger if signal from crank sensor, with hei spark plug tester ,read to coil wire and spark plugs wire if spark , depends wich engine
if c3i coil and module the module could be the problems you can check it before replace
hope it helps

cannot adjust or check engine timing it is not adjustable
it's a c3i coil and module system
there is a timing on timing chain adjust with mark
and advance timing is done with module

Not possible.... same as with the C5i I posted on. By the way, you don't need a dual link cable to run either the C3i or the C5i with the DX2 card..... single link DVI only is fine.

Can we back up??? So there is no Voltage getting to where? Is there Power to the Starter? Power to the Pump? Power going into the Computer but no signal coming out?

For your Plana Dome C3i you can get the drivers and CXtra calibration software under the cx section at ndssi.com. You must use a DX2 card (eBay) and XP. No go on W7 for those.

Hey there.

Coil packs are replaced not repaired if found to be defective. --- DISTRIBUTORLESS IGNITION SYSTEMS Starting in 1987, some models came with engines equipped with a Computer Controlled Coil Ignition (C3I) or Distributorless Ignition System (DIS). Fig. 1: Triggering system used on the C3I fast start system
Fig. 2: Electrical schematic on C3I ignition system Both DIS and C3I system consists of the coil pack, ignition module, crankshaft sensor, interrupter rings and ignition control module (ICM). All components are serviced as complete assemblies, although individual coils are available for Type 2 coil packs. Since the ICM controls the ignition timing, no timing adjustments are necessary or possible.

eBay..... search for DX2, and also under Planar Dome. You'll need the software from ndssi.com, under the cx section.

The module is located under the coils.
