I have a question about the alternate speed input, the Kpro4 vss input and the original vss are they both to display the same values?

No they will not.

[AREA876]

Using the VSS input for the alternate speed on kpro 4 will the ECU know what gear you are in ?

[Spunkster]

I believe it will.

[AREA876]

I am having problem with my alternate speed set-up. The input works but when viewing the datalog my gear is not switching and I am also getting a VSS error.

What sort of transmission speed sensor is it? How did you set the pulses per distance?

[AREA876]

The sensor is getting it's reading from the gear by the final drive, I currently have the pulses maxed out at 499999 per mile and I still can't get speed to match GPS

Have you tried following the instructions listed at: https://www.hondata.com/tech-alternativ ... ngine-swap

[AREA876]

I have tried going lower with the pulse but the reading seems to get worst. At 499999 it's about 10 mph off, but I still get a VSS error

[Spunkster]

What transmission are you using?

[AREA876]

Transmission is V2M3 from a Honda Stream

[Spunkster]

Does this us a counter shaft speed sensor?

[AREA876]

No, sensor is coupled to final drive

[Hondata]

If the speed sensor is the final drive type (not the 3rd gear sensor) then your pluses per mile should be in the 10,000 range not 500,000 range.

[AREA876]

Setting the pulse to 10,000 per mile resulted in 336 mph
