Hi guys
apologies if this is on the forum already but I searched and couldn't find what I was after.
I have a DL1 sport and Dash 3.
The problem I think I have is that I'm sure that the reading on the AFR meter that I see when driving is slightly different to what is being logged by the DL1.
I have the following formula entered for the conversion in the analogue input :-
2. * x + 10.
I can't remember exactly where I got this from, it works but I'm not sure its accurate.
The Stack AFR meter I use works between 0-4v rather than 0-5v.
Could anyone clarify if this would be correct for the 0-4v output I'm using?
My feeling is that the car is richer than the DL1 is telling me when i look at the data.
Thanks in advance
Pete

Stack AFR meter 0-4v calibration
Re: Stack AFR meter 0-4v calibration
As far as I recollect you calibrate the ST3401 gauge to show a particular range of output on its own digital display and the 0-4v output is automatically calibrated to show the same range. So the question becomes : Is your display showing 10.0 when fully rich and 18.0 when fully lean ? If so your formula should be correct.
