anyone use afr gauge.... what one?

most seem to read max at 20:1........................
really need something that reads 30:1 so can tune to around 20:1

someone will correct me but I don't think 02 sensors read that lean once you hit 20:1 your already in dangerous country

you need to set everthing rich and then tune the engine lean not the other way around

we are talking diesel here not petrol, ritch means high egts witch means engine damage

Is this for Common Rail tuning?

[rxsmiddy]

nah this is for 1hdt tunning

Interesting, so for full power is it a stoichiometric tune or lean or rich? Sorry, off topic.

I run a pair of these on my 1uz, http://www.innovatemotorsports.com/products/MTXL.php

They go to 22:1 on petrol but the table states diesal to 99:1
They come with leads to plug in to a computer to change parameters,I only assume to set up for diesal
