Is there a way to reset ecu for a bigger fuel tank

I replaced my fuel tank with a 46 gallon tank. Is there a way to reset the ECU?

 

There are some threads here where people installed the larger tanks so search and check those threads.

Here is one https://www.tundras.com/threads/transferflow-46.75718/#post-1929303

 

What are you referring to when needing to reset ECU? Distance to Empty?

 

Unhook the battery for 15 min. Give it tank or 2 and see if it figures it out.

 

Good question! Maybe ask the tank supplier. I would think that they would know the answer.

 

Was hoping to be able to recalibrate it. Tried disconnecting and it just goes back to the 26 gallon setting. The manufacturer say to watch the gauge as you fill to see how much is at each 1/4 mark and figure from there.

 

If memory serves, mine has approx. 10gl when my low fuel light comes on.

I've stopped paying attention.

Might be helpful. I've heard mixed reviews

 

That sounds about right regarding the low fuel light. I love the distance without having to stop when towing a trailer.
