You could do it yourself if you fancy. You'd need a Tactrix cable and a copy of Romraider and ECUFlash.

restricted to 120 is strange thought the japs equiv in mph was 110, ask a mapper to have a look for you they might not charge much if your not having a full remap. you could ask jollygreenmonster

The limit's 117mph, it might look like 120mph on the clock. Doing it yourself with the tools I mention would take about 5/10 mins.

tactrix - You could get a cheaper 1.3 cable on ebay for about £60.

RomRaider - Open Source ECU Tools | RomRaider / Rom Raider for info and ecu editor.

EcuFlash - OpenECU for the ecu flashing software.

Probably not cost effective, but it will get the job done.

I would have done it for you, would have taken 5 mins, I wouldn't have charged £100 though, ouch.

Try Zen Performance as they are only down the road from you in Wellingbourough and can derestrict it etc..

the software I use (EcuTek) is geared towards a full remap and therefore has costs involved and therefore not really suited to just loading a map with speed limiter upped.. would be cheaper to fit an electronic derestrictor, or leave it restricted and change exhaust etc and incorporate derestriction with a remap to gain more power etc..
