Well, i've gone and done it!
Whipped the Ecu out today, quick bit of soldering and popped it back in.......
My ECU now has 2 extra chips and a bit of wire!
It started first time, and what a difference its made!
Honestly, its a different car.....it has....erm......what the word the V8 boys use.......Torque!!!!
Not huge amounts, but enough to make a big difference. Engine note seems softer, less 'rattly', gearbox becomes more flexible and the rev limiter has gone....
At first I didnt notice that the limit had moved (i dont know where it is now, and dont intend finding out!) but it just means that you tend to change a bit nearer to 9000 than before. The engine starts to run out of steam then anyway, so its a natural point to change.
I really can't recommend this modification enough, the difference is quite dramatic, without making the car frantic or over 'harsh'.
My first thoughts were that the engine felt like a 1.1 or 1.2 litre block, the gears seem more useful as you dont have to be in any particular gear to accelerate.....oh and the speed limit has gone but 90mph is not to be recommended with the roof down!!
Watch this space for an upgrade service costing around £100
