WTF is my ECU doing?

So everytime I've changed my intake (Stock to Injen SRI to Type-S), my gas economy jumps from it's regular 18.5 up to 24 MPG. It only gets that kind of MPG for about one tank after I've switched...

Why is my ECU adjusting and giving me a worse gas economy?

It's just learning the new setup. It'll calm down in a little while. Not sure why, they just do that.

Its probly reading more air flow and wanting to put in more gas to make up for the increasd air flow. But just like both the post above mine it should clear up when it notices that the change in air flow isnt that much.

Re: WTF is my ECU doing?

Strange. I owned a Del Sol SIR a while back and when I put my K&N filter slapped onto the rubber pipe it was fine and VTEC kicked in at 5650rpm. Shortly I put a proper pipe on it and my crossover dropped to 5400 and stood there. Same here change in ECU.

My BB4 now has a Spoon ECU and it didn't change anything when I put the pipe.

Re: WTF is my ECU doing?

Hoping someone will chime back in on this. My engine has started to sound a lot throatier ( not really a bad thing ) But my gas economy is down to almost 14 MPG......... WTF!?!?!?!?!? been about 2 months since I put my type-S in. I think my ECU is just going crazy.
