need to flash ??

[Mr_hd]

Hi there, a newbie question, but just to know if i'm right.....

If you change air filter, and catback exhaust, you've to flash your PCM ?

or the PCM "feel" the new situation, and change the data automatically ??

thanks for your support.

No need to reflash for a catback and filter swap. But, you might want to anyway, it will make a difference in the way the truck runs, all for the better.

I would disconnect the battery to reset the PCM, let it sit for 10-20 min, then drive away!! That will get rid of any adaptive memory and can relearn the new mods

Should have thought of that myself. One thing I learned is after reconnecting it, let it idle for 5 minutes with the AC off, then another 5 with the AC on. I was having some stalling issues and Dan from DC recommended that, never had a problem since.

I am going to have to try that...my truck has stalled 3 times since I installed the new PCM.

Yes you should always disconnect the battery when adding mods.......as Red stated, its lets the computor learn the new setup. No flash nessasary.

Thanks all for the reply, I'll desconnect battery, make mods, and then I'll let it idle for 5 min. w/o AC and than other 5 min. with AC on. :top:
