Which of these is best
MRT Lamda link
or Dawesdevices AFR meter
Buget is a big factor so these are the only choices unless there is somthing else out there and I'am not confident enough to do a DIY jobby
Cheers

It depends what you are going to use it for, I just went for a standard autometer AFR, I got one more for peace of mind than for anything else. The modified gauges are set up to show between about 0.78 & 0.98 volts so each LED is 0.01v, this means you won't get the flashing lights at idle & cruise.

But they are all pretty much a waste of time unless you calibrate them with a wideband. A sensible AFR can be 860mV on some lambda sensors and 910mV on others and there is a world of difference. eg a narrowband lambda voltage of 890mV can be a 20% difference between cars in actual AFR which is the difference between being a blow up from getting too hot and being too rich so it is slow.
You can build one for £10 if you can solder and look out my old thread, but I don't run one these days - I have a wideband, and if I didn't have that I wouldn't bother with a narrowband AFR gauge either, would just run a knocklink. If your car is tuned, then if it is running lean it will probably det and the knocklink would give you some warning. You can overgauge your car and not know how to read them all. EGT would arguably be more useful.
Oil temp, boost gauge and knocklink would be my choices - first to tell you when you can boot it, the other two are obvious. Low oil pressure probably just tells you you have blown your engine up or need to strip it anyway?

John,
Mine went very odd when the Maf failed, some of the lights faded and it flickered all over the place. Guess that's just as it is failing - as the voltage flies around?
