Speed limiter

Recommended Posts

This is random but its been bugging me

 

Once upon a time i had a stock ecu with a speedo converter which had one wire going to the pink wire on the ecu to remove the stock speed limiter

 

I changed to a mines ecu which didnt need the wire connecting as it has the speed limiter removal built in

 

Ive gone back to a stock ecu and haven't yet put the speed limiter wire back on but the car is not limited and keeps going

 

Is there another way my car may have been de-limited that i don't know about?

 

There are no little hks or similar boxes hiding anywhere and none of the ecu wiring is tampered with apart from the FCD :blink:

Its a strange one i have no fault codes as i have checked that

 

Before doing the manual conversion i did have the o/d and trac control lights flashing all the time but no codes

 

They still flash now and have done since i got the car pretty much

What methodf did you use to check you have no error codes? Did you see the small engine light come on all the time (i.e. on and no flashing)?

 

If the pink wire input is left unconnected (please confirm this is what you currently have), the ECU would surely log an error. The alternatives are 1) assume that the speed is low, so allow further acceleration, in which case no need for a delimiter device! or 2) assume that the speed is too high, in which case you wouldn't be able to accelerate from stationary at all.

Sorry i don't think worded it properly

 

By not connected i mean the speed delimiter wire coming from the speedo converter thats not connected to the pink wire at the moment

 

The pink wire on the ecu remains stock and was connected back together when the mines ecu was fitted previously

 

Ive since gone back to stock ecu and the pink wire is still connected as it would have been stock as i havent yet connected the wire from my speedo converter

 

So whats confusing me is the wiring is now as it was originally, with no delimiter connected yet, but the car is not limited

 

Hope that makes sense
