Scangauge is not accurate on my new Corolla

Hey guys,

I just got a 2014 Toyota Corolla Le Eco and have about 5 tanks on it. My SG always shows 2 to 3 mpg low. The engine size ect is set correctly. I took it out of our 2001 Buick Century that we traded and it was very accurate in that car. Anything I need to do differently with my Corolla?

Have you done a calibration on it?

Even if you don't calibrate it initially (which one should), each time filling it up and correcting it should slowly walk you into the right zone.

What is the calibration you are talking about? But like Ulta said it should be accurate by the 5th tank.

When you fill up the car, you tell the SG2 that you filled and it will ask how many gallons you added and price, just keep adjusting till it matches. Try to fill at the same pump while doing it and fill it the same way, 1 click, 2 clicks. After 3-4 tanks it should be good.

Use the same fuel each time, it doesn't adjust for E0, 10 or 15. It uses airflow to calculate fuel, with higher E blends the engine needs more fuel to the same air so it won't calcuate correctly.

I have had this SG for 3 years and was using it in my Buick Century and it worked great so I know how to add the fillups, just trying to figure out why it wont calibrate to my new corolla. Is there a factory reset or could it be something with my new car?

Are you sure it uses airflow to calculate fuel? I thought it metered the fuel itself.

Do a factory reset - red button, more, settings, reset (or something like that). Then tell it about your new car - engine type, fuel, size - and start again.

Only other think I can think of is the DFCO isn't being recognized, it doesn't in my Cobalt but did in Malibu and Stratus, never tried to figure out why not, guessing the Corolla is a manual.

My DFCO is indicated on my Torque App as 0.00 CC/min, but EONC reads zero when my speed is over 60 KPH otherwise it reads the normal 10 to 12 CC/min.

One other tip is when filling don't tell the SG EXACTLY what you put it, adjust in halfway between what it thinks and what you got.

If you change styles (e.g. a fast journey where most previous were slow) it will get inaccurate.
