lsvtec obd2b-obd1 converter harness w/ kenji chip , just before 5200 the tach goes crazy, back and forth.. any suggestions?

 

What kind of tach

 

stock tach

 

Sounds like a loose connection or ground.

 

It could be the ignitor, I had the same problem.

But mines did that when I went over 4000 RPM.

 

any other suggestions? Dizzy is brand new.

 

I have the same exact problem, however, mine is with an OBD1 H22. I ended up just hardwiring the blue tach signal directly to the stock tach. Wish i could've figured this out.

 

this fixed the problem? could it be a loose connection on the obd2-obd1 harness? which wires are for the tach?

It fixed my problem and I rev up to aroudn 7700 now. Off the dizzy it is a blue wire. I don't know which wire you are looking for in your harness. You'll need to get a diagram to figure out which in your cluster is for tach signal.

I believe it is blue as well, but don't quote me.

 

thanks man
