hello, my name is gabriel, if anyone can help me please do it, my email es gnm50@hotmail.com, i have two problems.

the max speed of my W124.032 E320 1994, is 205 Km/h so i know the others ones can go at 230 km/h, my car have powerfull but there is some kind of electronic limiter that does not let me go more fast.

the engine stops sometimes, the electric system of the car still on, but the engine get off, the fuelpump have problemas because when the engine stops i listen the fuelpump get off, do i have to buy it new? or it is a electric problem?

if anyone know how to power up my car, please tell me how, i like the speed, im sorry for my english maybe is not very good, im from another country, from venezuela... thanks everybody.

note, the wiring harness is new. i just want to know how to go really fast, power up my engine

You would have to swap in a new ECU without the speed limiter. Simple work but you'd have to find one first. Ebay is probably your best option... they were available last time I checked and not that expensive.
