Looking for a cruise control with ECU input


Recommended Posts

I'm looking for a cruise control unit with an ECU control input. It would have to be a drive-by-cable model. I believe some WRX models (or just Imprezas) had CC since the throttle body has support for a second throttle cable.

I want to use it as a cruise control and to increase the throttle opening for cyclic idle, thus requiring the ECU control input. I guess the actual cruise control could be done with the ECU as well?

Do you folks know any cruise control systems that would work for this purpose?


Edit: My car is 1999 WRX GC8

My recollection of the old cable cruise control like Subaru and Honda used in the 90s were they were vacuum controlled, so I don’t think it will be any good for anti lag as you will have no vacuum.

Good point.

E-throttle could be a solution but I don't want more lag in throttle response

You wont. You will not notice any lag in a dbw unless it is programmed to have it. Period

Well, that's good to hear. I might go DBW after all..

I assume most of the OEM solutions have a deliberate lag added to them (something to do with emissions & economy)?
