Speedo - speed limiter

Wired in a universal speedo, i know they dont give an accurate reading but was sick of it saying i was doing 0 mph lol.. Anyways, driving along doing around 40-50 mph and speedo was saying i was doing about 110 mph, as soon as it got to 117 mph it would cut the power.. My ecu still restricted to 117 mph???

I was lead to beleive its the ecu which limits it i had a z4 fitted into my uk classic which restricted it to 117mph then when i put a chipped 7d ecu in its was back to being unlimited . Never changed speedos ect

The speed limit on a jap import ecu is in the ecu software, it's 112mph (or 180kph) not 117mph, to remove it you need to add a kph to mph converter/speed delimiter box to the back of the clocks if its a 97-00 import, this intercepts the speed signal going back to the ecu converting it to MPH from KPH, this moves the speed limit to 180mph, if it's a 92-96 you can fit a simple converter to the speedo cable/gearbox that does the same job.

Its a z4 ecu out of a my95 import, with uk my00 clocks

You need to fit import clocks with a converter (speedo cable type) for it to work.
