Ok, we all know the EMS forum moves slow as hell

JP said I can get around the ignitor with a 6A. He said to follow msd's instructions on wiring, but the instructions has it wired in between the ICM and the coil.

There is a magnetic pickup input on the msd consisting of a + and -.
Can I hook pin A21 (Coil1) to one of these, and if so which one? What do I use with the other msd input after hooking A21 to it?

Please help.....my car is dead in the driveway cause the POS honda ignitor. How can I fix this tonight????

I havent tried it but i heard from a reliable source that you can trigger the white msd trigger wire from the ignition trigger from the ecu.

If it works let us know, i would rather trigger my 6al from the ecu directly.

93LSivic

OK, I will give that a try. Im just scared that I will smoke either the ems or the 6A

93LSivic

Ok, well i tried it. No, it didnt work.
Right now im actually trying to figure out wheather its the coil or the ignitor....still thinking its the ignitor, but who knows.
Had a couple beers to finish off the night. Im gonna get a good nites rest and figure it out tomorrow.

Anyone else have some ideas on what i may be doing wrong?

93LSivic

Anyone else have any ideas on this?? Need to get this thing up and running today.

You should be able to run the ECu signal right to the 6A without any issues. problem is if the 6a is feeding the stock coil and the coil is bad, you are screwed.

If you do bypass the ignitor with the 6a your stock tach will NOT work and you will throw an ECU code.

So, here is my suggestion:

1. Swap the coil. See if it works. (Honda internal coils are notriously crappy).
2. Swap the ignitor. See if it works. (they ahve been recalled multiple times).
3. Install the 6a, it will make the ignitor last much longer by reducing its current throughput. (And improve spark)

Ok, I found an MSD cap with external coil.....whcih should i use the blaster2 or ss??

Ive narrowed it down to the coil being bad, and or a combination of the icm and coil.
To wire it up im gonna just use the tach output from the msd6a to the blue wire on the distributor which is the tach wire. Shouldnt be a problem--crosses fingers--wiring everything together. JP from AEM said I should be able to do it with no hickups.

I will let you guys know how it goes in a couple of hours.

Ok, hooked up the MSD, cap and coil yesterday. Everything went perfect. Bypassed the shitty oem ignitor and the coil all together. Only thing you have to do is use the tach output from the msd box, which gets wired to the tach lead on the distributor (edited). I would suggest this to anyone who is having constant problems with the crappy oem ignition. Hopefully soon I will goto a full coil on plug setup with my EMS.

Can the tach output from the MSD be wired in at the ECU or does it need to go back to the distributor?

93LSivic

It can be wired back at the ecu no problem.

are you sure? Ive always seen just the opposite, MSD equipped cars eating up ignitors...

also 93LSivic, which wire on the alternator did you run the tach lead to?

93LSivic

Geoff, the tach lead on the dizzy is a solid blue wire. Just cut and run the output from the 6a to the harness side of wire.

Im hoping your meaning distributor instead of alternator.

thats why i got confused

Ok, just got a quick question for you guys that ditched the stock igniter..

I just took a look at my old distributor with the good old busted igniter and I see the two wires that usually goto the msd.. The black/yel which is the switched +12v, and a white/green or white/blue (colors are faded) which I assume is the (-) negative trigger..

So you guys are saying to ditch the igniter you simply connect the white/blue wire going to the igniter and run that for the (-) negative trigger for the msd? Then connect the tach output from the msd to the blue wire (which is the tach signal right?) coming off the igniter?

It makes sense to me but I'd just want to make sure. I'd sure love to get rid of that damn crappy igniter. Thanks guys.

My apologies for bumping an old thread, but can anyone else confirm that they have done this and if it is working properly?

I think you need to use the amplifier in the thread above. I was going to try it but havent gotten around to it yet.

If you're ditching the stock ignitor, you will need the above buffer circuit.

Does anyone have an extra ztx857 they would sell me or know of a readily availible equivilent?

Iam going to give this a shot also. I've gone through 2 igniters and a coil in a year.

b_ron007

YOU do not bypass the igniter.....you still use it. just wire it up like ur suppose to according to MSD instructions. i have AEM EMS and MSD 6A with blaster coil and a cap i had to modify to run the external coil.

According to the EMS Forums. You can do either. 93LSCivic has done it to his car without problems
