I have a 1993 eg coupe ex with a B16 swap everything works fine on my cluster exept my RPM gauge i tried a different cluster from a friend and still not working, so i know its not the cluster. Im stuck what can it be. If you can help it would be great. Thanks

 

you'r wire set up might be different what obd sys is you'r engine have a look at these pics

I have an obd 1. Any advice ie helpful. Thanks.

 

Try your vss
Google it and good luck

 

if his vss was in-op his spedo,trip and vtec would not work. It's not related to the tach.

 

Thanks for all the help. Still havent found the problem but not giving up. Im new at this honda stuff..lol.

 

There's a green wire that is for the tach that should go to one of the cluster pig tails.(wish i had a pic to show you) but search how to install a shift light as it requires splicing into said wire. in short look to see if said wire is there and is giving a signal.

 

I have a similar problem with my b18a1 swapped eg. when i bought the car it had a p28 with a vtec map and it ran like **** but the rpms were good. as soon as i got a p75 in there the rpms were off. i read an old post somewhere and some guy had the same prob and he fixed it by swapping in a gsr cluster

 

Oh ok. I bought the car with the swap in it already . Let me know what you guts think is a B16a2 obd1 with p28. Is that good or bad?.

 

I will search for that thanks for helping me.

 

b16a2 can be obd1 or obd2(or with a obd2 to obd1 jumper harness) AFAIK. p28 is fine

 

Ok. Will check it out tomorrow and i will get back. I will check the wire thanks for all the information

 

This has happened quite a few times....


Unplug the distributor connector, and then measure how much resitance at the blue wire terminal. If the resistance reading is low (100 Ohms or less), then there's a short.

I bet the blue wire is broken or disconnected somewhere between the distributor and cluster.

 

near your driver side strut tower / clutch master area there is a single blue wire with a plug at the end of it.. if you connect that wire with the darkest blue wire on your dizzy, this should solve the problem

 

ok i will try it today thanks for the help. i will let you guys know the results later today.
