Computer Re-Learn / Re-tune

[ss~zoso~ss]

i've heard something about disconnecting one batt cable and the computer will have to relearn all the mods on the car, i'd like to do this because i've had my car in storage for a couple months now, and im going to put it back on the road soon (march 8th ) yea!!


also would it be a bad idea to do this if i have old gas and fuel stabilizer in the tank? should i just burn off all the old gas and then do this?

No need to reset the PCM - I'd just fire it up and go.

i know i dont have to do it, but if i wanted to how would i go about it



are you trying to say that it does it constantly like all the time when u drive?

This method doesn't require any tools, less wait time:

PCM Reset

Turn key on, don't start car
Pull PCM BATT and PCM IGN fuses in engine compartment
Wait 5-10 min
Turn ignition off
Replace fuses

Idle will be grumpy until it relearns.

alright i remember doing that when i was trying to get rid of a SES code

It won't magically re-tune itself because you disconnect the battery. If you want it to really run better and gain the maximum amount of power from your mods then you need to invest in a real tune.

yea i know that but i'm broke as a joke, and i dont have enough mods to make it worth it

Thanks for posting the reset procedure.

[rwd_boostdscoobLS1]

there are certain procedures that can also initiate the fuel trim reset... if you know anyone with a high dollar scanner they can reset the fuel trim learn...on some vehicles with the key on but not running pushin the brakes so many times can activate the computer to relearn its tables..

[rwd_boostdscoobLS1]

some tuners can include the LS1edit install in the price of the initial tune..

hope some of that was helpful..

depends what your needs/wants are.........if you remove them you will get more power out of it, but it is illegal.........for starters

I just pull the neg cable...put the key in to the run position for a few seconds to drain any capacitors of energy...take the key out, reconnect cable and wahhlahh...let it idle under a load(a/c on max...defroster..etc) for 5 mintues....drive it like it's not yours for 20 mins...and you're set. You'll know when you actually forced a relearn...the engine will want to die when you first try to start it.

I have seen good gains from people with no mods, it is always worth it if you can find soneone who is good at it that can do it for around 100
