ECU reset- Any negatives?

Are there any negatives to resetting the ECU? Aside from taking some time to re-learn your driving habits...

 

are you just talking about discoing the power?
No issues. Drive aggressive and it should relearn on a 2nd gen.

Edit: clock, radio stations.

 

Yeah I just meant disconnecting the battery for 15mins.

 

youre golden.

 

You can just remove the ECU fuse for about 20mins.

 

No negatives, but your gas mileage may take a bit to settle in after a reset.

 

I've gotta ask, why are you resetting it?

 

I just always been curious. Mine has reset a couple times when I've disconnected the battery to do some un-related work (bulb/headunit swaps, splicing, etc). I'd always been curious how after I do this, the idle seems to be at really high rpm for several start cycles. Now I realize it's probably just settling into the new ECU settings.

 

I recently had to replace the positive terminal on my Truck, Did not touch the negative terminal, truck runs, fine no codes. went to get smog and the guy said, I did not install properly and need to follow manufacture procedure on Your year and model? I cannot find in the owner manual or service manual what he is talking about? Does anyone know?

 

There is a time period to do the readiness monitors test. You must drive and wait for them to be complete before doing any vehicle inspections.




below are the 4 tests it will run and need to be complete to pass in smog states.
