ok i have a 99 em1 with a b16b swap (obd1) the em1 as u know is obd2..my dizzy just went out and with out think i ordered a obd2 dizzy for a stock b16,so now my tach doesnt work. so my question is instead of running the blue wire is there a stock dizzy i can order that will alow my tach to work?? like maybe a obd1 gsr or delsol b16?

 

Up!!

 

What's up with the lack of help??!!

 

I'm confused you have a EM1 or EX.

If you have the stock wire harness, just order the TD-81U stock EM1 Distributor (and you are good to go).

You mean "b16a - obd1" because the b16b are obd2 and this dizzy should be plug and play.

 

Em1 is what I have with a b16b swap...i ordered a stock em1 dizzy..now my tach doesn't work. I just assumed the b16b was obd1...

 

Could the ecu be obd1? Or maybe just a bad dizzy? I will point out the tach does bounce maybe a 1/8 inch when u first start it..but thats it

 

For be sure check your old distributor in the top bolt base.

Your harness has to have this plug? Right.

Idk about the numbers but the plug is the same...i had to give it to them for a core. I'm sure its just a bad dizzy. What I get for getting it at auto zone. Life time warranty is the only reason why I did...

 

If the b16b is a obd2 then I shouldn't have a jumper on my ecu right? Because I do

 

Does your car have a conversion harness between the original plugs and the ECU? Or check the ECU code i.e. P28, P2T, etc.

But no matter what ECU you have obd1 or obd2, you should use obd1 or obd2 distributor. So you use the one that plug directly to your EM1 harness (TD- 81,84,86,87).

 

I only have one 02 so its not obd2...wasnt the b16b from 97-98 obd1?

 

Yeah there is a jumper between the stock harness and the ecu

 

No, 96-98 obd2a - 99-2000 obd2b.

I'll give a try to a other distributor, if your car was working right and the plugs are the same. Then maybe you get a bad one.

 

The numbers are gone from the ecu but it has Jan 30th 92. So its obd1

 

Yes, most sure is a p28 or p06 chipped. the two of them just look for one 02 sensor.

But still you can use the obd2 Distributor.

Bad new dizzy or check the connections in the plug ( the aftermarket distributor plug pins tend to move to the back and not make contact).

 

Ok thanks for your help ��
