You are right, but:
- Nobody sells you the new MBE in an open state, you buy a locked one....so not for me.
- Making something by our own is much more satisfying than buying things ready made.
The "old" MBE-ECU drives the engine without problems, the only thing I was missing was a control system which show me when something has gone wrong.
As I understand it the newer ECU is a much faster processor than the 20 year old one, the one PW opted for against John Ravenscroft recommendation and can cope with more data input and each cylinder can be mapped separately. Also with the option for launch and traction control should you desire it. - Nobody sells you the new MBE in an open state, you buy a locked one....so not for me.

Sure, that is all correct (except that each cylinder can be mapped sep.). A new MBE ECU would be the best solution. But in this thread I show the possibility to improve the Original ECU or better, give a good way for monitoring certain values.
And I will repeat: At the Moment you can't buy a new MBE, which is plug compatible and not locked. If you know more, tell me !

Excellent work, looks brilliant
Will you make these/sell them as a complete kit if you have enough interest ?
Hi Michael,Will you make these/sell them as a complete kit if you have enough interest ?
probably not. If I would sell these as a ready made kit, I would have the problem with warranty and other things....
I will make a How-To with parts list and connection details. I will also publish the software so everybody can use it. But I won't publish the Source-Code.
This weekend I mounted all the parts in my car and today I did the first test drive.
It works :-)
Yes, perfect. You could see that the car runs a beautiful Lambda 1 when there's not so much load, but if you push it the mixture goes to a very good 0,85 (thanks to Joolz :-) ).
There are only some little things to do, as the Lambda values are a little bit nervous (they jump for example between 0,98 and 1,01) I need to program some 'damping', so it's a little bit smoother.

Hello oliver,
My name is Yoga, I am student from Indonesia. Polytechnic Batam.
I'm trying to build Wideband O2 Controller, with a self-made controller.
You said that you will share how to for the project. Did you already share it somewhere else?
Can I have it? Because I really need it.
Thanks a lot before
