So the only thing left on the LS1/RX-7 swap is to get the speedometer working.

I am wondering what the paramter is in HP tuners that changes the speedometer PPM output?

The PCM already has my tire size, and rear end ratio input correctly. Heck when I have a scanner hooked up the speed sensor output is right on with my GPS. However, the speedometer is not reading right.

I got another speedometer and it reads the same.

can someone help tell me what the parameter is so when I take the car to get tuned I can get it fixed?

Thanks!

 

Is your gauge cluster or speedo for the same car as the PCM your using?

 

That doesn't matter if there is a parameter to adjust the PCM's ppm output.


But if you must know. Its a Honda Integra Speedometer in my RX-7 Cluster. originally the RX-7 speedometer was mechanical which is why the Integra electronic speedometer had to be retrofitted.

Several others have used it with great results.

 

Bump, anyone?

 

bump again, no one knows?

 

I am confused about how you could edit the tire size and gear ratios and not see it. It's clearly right there in the Speedo editor marked "VSS Output Pulses per"
