I hope that I am not putting this in the wrong area, if I am please move it to where I should have entered it. I just wanted to let you know that recently my son has bought and oxygen sensor and small PC board that we have made up a chamber for the O2 sensor to fit into and a sniffer pipe that he placed up the tail pipe and he has connected it to a lap top computer and he now gets air/fuel ratio, RPM and MAP sensor readings which are recorded on the lap top so you can see what is happening. I don't know if it can record other information but it seems to work very well, he bought it try and sort out mixture problems in his TA22 Celica with a 2TG/3T hybrid engine. This is probably something that you are already aware of but I thought that I would let you know anyway, I think he said that it was an Australian designed and built system. The O2 sensor and PC board only cost him about $300 Aust. which I think would be less than 140 pounds in your world and then it took us about three or four hours to make the chamber and pipes to hook it into, I have no idea how long it took him to set up after that.
