KPro V4 Questions

[Sim]

Hey,

Currently in the planning process and am trying to figure out if I can run KPro with my setup. I am swapping a k24a2 with a e153 MR2 trans into my 1992 MR2 and had a couple of questions:

1) Using the "alternative vss input" should the V4 be able to read the vss coming from the trans?
2) When trying to buy the KPro here:
https://www.hondata.com/?_route_=kpro
It says that the base 02 - 04 rsx auto ecu can't be used. But on this website it says you can:
https://www.hondata.com/tech-alternativ ... ngine-swap

Basically, I just need some clarification to make sure that the V4 will be what ECU I'm going with.

Thanks in advance,
Simeon

The ECU will be able to see the signal input to the K-Pro, but the cluster will not.

Info on using an auto ECU can be found at: https://www.hondata.com/tech-alternativ ... ngine-swap

I would recommend not using an auto ECU as it is more limited and has some compatibility issues.

Thanks for your response! Is there a spreadsheet or some info as to what its limitations are?

Info is in the link above.

So the only limitation is that the ecu won't work with cruise control? Not trying to sound smart or anything, but maybe I'm missing something?

There is also no way to send the VSS signal from the ECU to the cluster.

Hello Spunkster,

I am a little new on this, but when you say, " There is also no way to send the VSS signal from the ECU to the cluster " .

Does this mean that if I use an AUTOMATIC ECU, that I will not PHYSICALLY see the speedometer needle go up and down on the gauge on my car's dashboard ?

If yes, is there a solution for this ?

Would this same issue also occur with a Type S RSX or a Base RSX MANUAL ECU ?

Would a 37820-pnd-0a6 or 37820-pnd-0a8 ECU have this issue ?

Hello Spunkster,

I found a post on VTEC Academy concerning the VSS.

" HONDATA SPEEDO FIX PT2 "

I also found a video by VTEC Academy at . . .

Would this solution work concerning the VSS Speedo issue for an AUTO ECU using KPRO v4 ?

This will not work on ECUs that were installed by anyone other than Hondata.

How can you tell if Hondata installed the ECU into the PCM if it was bought second hand?

What is the serial number that is on the K-Pro board inside the ECU?
