when i was reading over the paper work at the bottom of the installation instructions it said to reflash the ecu to "learn" of the intake, disconnect the - lead on the battery. should i do this i would rather ask u guys than some stupid mass produced directions.

 

you will probably get mixed answers on this, i say go ahead and do it leave it off for like 30 seconds and it will be cleared.

 

wat r the possible problems it can cause tho? cause it said do it at your own risk

 

resetting the ECU is like just unplugging a running computer.


it CAN hurt it, but not likely

 

if your scared to reset your ecu. then leave your car on for 15 mins and let it idle... dont touch it. ecu will reset that way also.

 

why dont you just do it

It's not going to hurt anything. You have to disconnect the battery when you put a new battery in, or change a starter or alternator, right? It is going to reset the PCM, not a big deal, you'll be fine. If there's any codes or if the CEL is on, the codes will be erased and the light will be off until the computer finds the problem(s) again.

What damage can it do? The worst it can do is erase the preset stations in your radio and reset any clocks in the car, that's about it...minor inconvenience.

Now, what will it do for you? Probably nothing. It's highly unlikely that you'll gain any extra power at all by resetting the computer...not worth the hassle of resetting the clock(s) and radio stations IMO.

 

what do you think happens when you change your battery? you have to disconnect it. what about bringing it in for testing. disconnected. what about when you buy a swap, the ecu doesnt come with a battery pack.

 

thanx for the answers, i didnt trust the directions.

 

It probably says that just in case something random happens while you reset the ECU. That way you can't sue them.

 

if you have an obd2 disc. battery will not reset ecu. you have keep alive memory. the reason why you even do it is to relearn the iac. just let it idle for a while

 

how long should i let it idle?

 

if your scared to reset your ecu. then leave your car on for 15 mins and let it idle... dont touch it. ecu will reset that way also.

Damn i never knew that ... learn something new everyday

 

Ok well...a couple things.

-No it will not hurt anything if you do this...like it's been posted earlier, worst it will do is reset your radio stations.

-resetting your ecu allows it to relearn fuel curves; this is why a cold air intake usually produces more hp. The IAT sensor tells the computer that the air is colder/more dense with oxygen, and in response, the computer can add more fuel.

P.S. *If you are working on/replacing your battery, you can avoid losing your radio presets and other settings by leaving the car running while you change the battery.*
