SGII someone guide me...

[Project84]

I've had my SGII for a while now and I cannot seem to get it dialed in enough to produce accurate readings.

What do I do about the cutoff value? This is in my '96 SL2, I tried leaving it at 24, info was innaccurate, I tried setting it to zero, info was innaccurate.

I set, and saved, all vehicle info, engine size, fuel type, tank size, I even added 1 to the engine speed because I put slightly bigger tires on the car than OEM.

I can never get the "to empty" to be accurate and I can never get the average MPG to be accurate.

Anyone know what MODE to put in for an SL2? I think it reads VPW when in MODE.

Just getting frustrated w/ displays not being accurate.
