Richard - after looking at the innovatve products I look for alternatives and found this:

It is the Zeitronix Zt-2 and seems to be a brilliant bit of kit and much cheaper too. What do you think of it? The user input can log any 0-5v signal so I was thinking about getting one of these to log knock:

I want to continue playing with the module. I fitted a new AFM today but it didn't feel like I got the power back. I logged the lambda (although only narrow band) and it stayed below 0.8, not sure how accurate it is. The second lambda sensor seemed to give fluctuating results (yes, there are two on this engine). I'll speak to Courtenays about this tomorrow. It may be that one of my lambda probes has gone funny.
I'll get the car running 100% before we have another go with it.
