Im having problems with the RPMS and the speedo in my 2000 civic si, I just swaped a turbo gsr into, the RPMS start to jump all over the place after about 5000 to 5500r and the speedo just wont work. the speedo did work for about 5 mins one time but then nothing. I swaped the cluster out with a friends but nothing really changed, and the speed scener worked in my last shell so I dont think its that. Also wondering why heater will not blow hot air ??? Any info will help thank you.

 

sounds like its a wiring issue...what obd is the motor??

make sure theres no wires detached or de-pinned from the jumper harness and check all of your ground wires....it could be an ecu issue is it throwing any codes?? are you running a chipped p28?

 

its a p28 tuned on chrome, no CEL's. checked all the fuses and all the grounds that i could without pulling the dash. ill be checking the jumper harness next.

 

Jumper harness is a good idea....

The VSS reads good at the ECU so we know
its good.

Any diagram for the cluster wires colors ect ect ? then we can check with a volt meter.
Wiring diagrams for dash harness please ? ??

Bump it up !

 

bleed the coolant with the heater running, you may have to remove one of the heater hoses and fill with coolant, everthing else to lazy to read right now

We fixed the heater !

Still no tack and rpm's hop around like crazy.
This is a gay problem at 15psi !

About to yank dash, any ideas ?

 

What color are the wires going to your IACV, MAP, and TPS?

 

stock 2000 si harness with a obd1 gsr swap.

 

TTT

still got no speedo and tack is jumping around

 

Change your ignitor and your coil, then the problem should go away.
