Question Ecu ...

I just reset my ECU, but when I turned back on my car, for some reason my AC seems way more powerful. Is this possible from a ECU reset? Hopefully my gas maps will be reset, and maybe ill get some better mileage! (Main reason for resetting ECU was horrible gas mileage, and yes i did check O2 sensor/air filter)

Any more things I should expect from the reset ECU?


PS: ECU resets are VERY easy

well did you reset properly .... by warming up the engine to operating temperature shutting it down doing the reset then restarting tghe car and let idle for 15 minutes so that it can learn the engine again?

if so sounds like your ecu was outta wack to begin with if your gaining that uch of a difference

I guess the eCU was outta wack to start with!

never take the positive terminal off... it will spark/ arc and that is not good... if your disconnecting the battery always take hte negative side off first
