Hi
I have a 05 Toyota Sienna v6
Initial results after hydrogen install gained 10mpg over stock.
After about 70 miles ecu started to richen fuel mix bringing mpg to 16 which is worse than stock usually 18mpg.
This vehicle has a maf ,map,2 afr and 2 o2 sensors.
What do i need to add to counteract my ecu.
Thanks
