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. |
I think both item is good value for money. Will be interesting to to know the total after adding the options. The LCD display and EGT probe is a must. Boost sensor is not need in your case as you have a map sensor already, you can log it on the user 0-5V.
72 samples per second per graph divided by 7 channels means 10 samples per second per input. It would ne nice if you have a few spare inputs.
I know very little about knock sensors - the nice ones uses DSP chip to analyise the knock and the not so good ones just have a tunable notch filter. I welcome you getting some useful tools to help tuning your car. It is too dangerous to to tune without them or rollong road hours can mount up very quickly.
Let me know when thing are back to normal again. If you have the wideband, you can check you MAF sensor daily.
