What he ^ says. The warning light is the exhaust heat warning light. You will need to short it otherwise it will stay on all the time. If your car was correctly mapped using a wideband then you can rest easy. The knock sensor is just a glorified microphone and different cars will have different readings depending on the mods. Injector duty cycles can reassure you that you are not maxing out your injectors and possibly leaning out. On the monitor you can choose the parameters to be displayed or you can display up to 8 parameters. There is a manual for the commander somewhere online. Google is your friend on this matter as I cannot remember off the top of my head how to navigate the commander (the double rum and coke I had earlier are not helping). I can post a link to the manual tommorrow, if you cannot find it.

Defo worth getting. When your engine is heat soaked the air temps go high and the timing is retarded upto 6 degrees to prevent det( unless someone changed it during mapping) your timing won\'t be getting retarded.
The RIAT sensor is so much faster and will be cheaper than a new mazda one.

Why is the vacuum only at -29mmHg, shouldn\'t it be closer to 5-600 when its stopped?

No, it should be at 0 with the engine off but the calibration is slightly out which is quite common and nothing to worry about, it\'s only for a reference.

This was after a 5 min journey under 3000rpm. So the knock sensor output looks wrong. Would anyone worry about this and get a specialist to take a look? Dodgy sensir?

Should get some time to fix the heat sensor next week, then that will be another tick off the liat.
