I have a 1980 Z1000H(inj). However I'm looking to replace the ECU control box with something more modern.
The original system works but is , at best, very course. Ideally I'd like a modern ECU which will keep the mixture set correctly at all times.
Can anyone point me in the direction of where to find a replacement ?
I know 'Power commanders' aren't available for this age of bike, however I understand there are other systems out there , some which are also programable from a laptop PC..
Any help appreciated !: <br><br>Post edited by: Wull777, at: 2007/01/05 06:06
I'm MegaSquirting my '81 GPz, which (if memory seres me correctly) is the same setup.
There are at least three limitations to the hardware of this system (apart from the control unit) that have to be dealt with.
#1. The injector bungs are actually in the head, not on the throttle bodies, and the injector style Kaw used is prone to overheat. The tendency for the injectors to overheat has often been blamed on the location (in the head, not on the throttlebodies) but my research shows that it's the injectors, not the location of them.

The injector on the right is the style Kaw used, the injector in the middle is the common one. 19# Ford 5.0 injectors are really cheap, and are like the one in the middle. But to use these require the removal of the head and boring the injector bungs out to 17/32.
2. The air flow meter that Kaw used is strictly stone age. MegaSquirt doesn't even require one, so you will have to figure out a new air cleaner setup.
3. Kaw didn't use a real throttle position sensor (that thing on the left end of the throttle bodies is just a "wide open" sensor). Any system you use will need a real TPS.
Everything else is just making it work. But, if you're serious about this, be prepared for what you're getting yourself into. It's not just changing the box.
