Car: 2000 Civic Si
ECU: p28
OBD2B
Not syncing. Has power and the red light flashes.
While wiring it up there was no wire in A22 so added one. Also tried A21 and got a code 4. Anyways im attaching an image of how i wired it up. Is this the right way? So far this has been a huge headache for 6 wires lol.

 

A25 and A23 should still be connected to ECU.
The CPR taps into those wires for power/ground.
I assume this part of your diagram is inaccurate as if wired like this the ECU would be dead.

The yellow and blue wires in the engine bay dont feed into the distributor.
They feed into the distributor harness, engine bay side.
The coils are getting power from the engine harness
And the CPR is outputting the tach into the engine harness (like the distributor used to)

 

Ill give it a try. (will have to wait till monday when im back at work casue thats where my car is) i have it wired like this and for some reason the ecu isnt dead, i was still able to connect with my hondata.

 

Muckman hit it on the head. That would fix your problem.

 

Tried it no luck, this is how i have it now.

 

Sub'ed - Been hearing of a lot of issues w/ this kit.

 

After swapping out my hacked conversion harness and redoing all the wires and finding a blown fuse, it started working. Now the tachometer isnt working. Any ideas?

 

Tachometer in the cluster, or through S300? Or both?

Your tach signal wire is solid blue @ C8 (IIRC..)

 

I dont have it at the cluster. i can see it on the s300.

 

I have sold a bunch of them without a problem. The problems come from the installers, not the kit.

Make sure the green wire is connected to the blue tach signal to the cluster.

 

Since there it no tach wire at the dizzy for obd2b do i need to wire it into A19 going away from the ecu?

 

tapped into A19 and it worked!

 

I'm willing to bet they were all installer issues like turbogixxer said.

I know my problems were 100% my fault...

 

have everything working now, but as i drive the car has a hicup where it falls on its face for a quick second. tried taking %25 out coil dwell and that did nothing. Next step is to try a different distributor.
