Hey folks,

I’m considering to fit a GTI engine into my classic mini. Most problems have been theoretically solved, but a big one is quite hard to get rid of.
I would like to keep my Innocenti Cooper speedometer, but don’t know what to do with the VSS unit. If I just unplug it, what would the engine management do?
May there be a way to fit the VSS to the speedo cable, or how does it exactly work and look? I’m new to all this fancy electric stuff. I’ve only learned to adjust carburettors and ignition with a timing gun, yet. :lol:

Someone in the miniforum used a megasquirt, but this would add another 250€ to my project. But as far as I’ve read this might the most practical way to get rid of the VSS?

Kind regards from Germany

GTi uses a mechanical cable to drive the Speedo I believe. No electricity

GTP

Yes, I know about the speedo cable, but isn‘t there a vss in the speedo Cluster?
It‘s a Mk2 engine, if that is important.

Vehicle speed sensor. I was told the ECU needs the driven speed to „know“ when to idle :?:

If you are using the ECU for the G13B engine (and why wouldnt you?) then you do not need the VSS. Idle is controlled by engine RPM, not road speed. Otherwise, if you are cruising and take it out of gear, it would continue at 3000rpm while doing 100kmph if you were in neutral.

Ok, this does make sense.
I had a chat with another guy who converted his Mini to swift GTI. He said he didn't use the VSS either. I doesn't made any difference, but the engine always gave the code no. 24.
But why did they add it, when it's not needed?
Quite confusing. :oops:

The VSS can be used for calculating the odometer if it is digital, along with logging etc. The VSS is usually part of the dash, not on the ECU, but I could be wrong.

There are many cases where people have put the G13B into a Mini, so there is plenty of reference material to work from.

“according to the manual , the only purpose of the vss in the gti is to control the idle solenoid valve , different vehicles use the vss in different ways , honestly id do your conversion and then decide later if you really need the vss.”

From another post on redline.
