Speedo car  de-limiter help

Good day to you all,

I want to use my arduino to overcome the speed limiter on my car. I've worked out the speedo at the back emited a gound pulse directly into the ECU. If the pulse is say > than 111mph the ECU shuts down. What I would like to do is duplicate the pulse upto say 100 then freeze it at that.

I am using the arduino for other things so I've already coded in an attachInterrupt which monitors pin2 can works out the length inbetween the pulses. How would I configure the arduino to output the same negitive pulse but throttle it so it doesnt go over the 100 needed ?

Many thanks

Steve

Do you mind me asking where you live?
It's just that, I don't want to be on the same road as you when you're driving your hacked auto.
Preferably in a different country.

OK, you said "mph", so I think I'm OK.
