mystery ecu - 33bhp or full?

[4130chris]

I have a cdi / ecu spare but I'm not sure if it is limited or not...
if someone could help that'd be great-

the numbers stamped on the thing are

F8T95771
MGT060
4326

Cheers in advance

Hmm good thinking, Can I use the numbers on a ECU I've just been handed to see if its actually got more juice? I've been told its an extra 18bhp I want to dyno test it but I think its exsactly the same tbh.

Can't you just plonk it it a bike and ride the bike?

Cant see how on a pre injected model although? although someone who knows more will be along soon,

ditto, think someone told you lies matt!

Lets all get a little more specific:

The 99-02 bikes use an Ignition Control Unit. This affects only the timing of the sparks. It isn't actually a CDI as it doesn't use Capacitor Discharge Ignition as it's firing method, that's a little old hat nowadays. This will not affect the power in any meaningful way, there certainly aren't 99-02 restricted units as it can't affect the engine enough. You can fit an SV400 Ignition Unit to an SV650 which raises the rev limiter, cutting the spark higher up the rev range, though I doubt this is a stunningly good idea for most of us.

The K3+ bikes have an Engine Control Unit. This affects Fuel, opening of the secondry butterflies where used, and ignition. There are 33BHP units of these. All others are standard, though you can re-map them to suit your bike better if you've changed the air filter and put on a full exhaust system for instance.

Thems the answers I was expecting, I dont know any different so I havn't bothered to mess about with it but now at least I know I have a spare CDI cos an ECU wouldnt work on my bike (2001). :) education in progress

[Dave20046]

What's the spare CDI (ECU?) you have actually for do you know?

it fits my bike, I've had a play but took it off again seen as I didnt know what it was doing. Originally its from a spanish registered SV.
I didnt notice a difference between that and my original unit during my little play but tbh after the last 2 weeks of stripping the bike down nothing was working as it should everything has now been replaced (this fortnight has cost a fortune), maybe now I'll notice a difference between the 2 units.

I am pretty sure F8T95771 is the standard ecu and F8T95772 is the restricted ecu for K3 onwards

MGT060 is full
MGT061 is 33bhp
