hey everyone
just installed my 2 day used limited silver joe z today at work
everyone one was laughing at me as it took me a while lol(im an mb usa tech )
but i wanted all the rings and collirs to be spaced evenly so....
well i must say it does add throttle response as you take off
one quick question
has anyone put it on and notice the engine running slightly diffrent
my example is i refed the engine to about 4 k to see what it sounds like
when the rpms dropped to about 2k it felt like a little bump in the engine
like it ran poorly
i just atributed it to learned its new airflow pattern
didnt know if any one might have expierenced that
thanks for any commments

if your car runs funny or bad after an intake mod you might just try to disconnect the battery for a while to reset the ecu.

 

If you followed the directions and reset the ecu, it takes a couple days (depending on how much you drive, of course) to recalibrate.

 

so by just disconnecting the battery it is supposed to reset the engine managment
computer ??? i think that might be a myth
engine adaptive softwear is softwear not somehting that you can just erase
has any one expierenced this and resorted to disconnecting the battery to fix
thanks for your replys

^ I thought that it's not erasing your engine adaptive software it's just that by disconnecting the battery for a period of time.. not just a few seconds more like several hours then the ecu will return to the base factory settings and have lost the learned adapted settings in temporary memory that requires a power source.

 

Im Not Saying I Know It All But With My Expierence With Mb I Would Say That
That Those Values Would Not Be Removed By Disconnecting The Battery
That Would Be Like Saying If You Diconnect Your Computer For Several Hours
It Would Loose All Its Info As Well
I Think Its One Of Those Miths Like If You Rub Ur Negative And Poss Battery
Calbes Together You Can Erase Fault Codes In The Vechile Hahaha
I Think By Me Just Driving It ,it Will Learn The New Air Flow Threashhold
Will See I Guess
I Cant Wait Unitll I Get My Tanabe And See How Much Better Flow The Engine
Has
Thanks For Your Input

well if you unplug your computer for several hours it retains the settings and such because there is a bios battery in there. If you take out the bios battery then yes you WILL reset the bios settings back to stock factory settings but not lose everything because the stock factory settings in the bios is burned into the chip. What you do lose is the data in temporary storage that needed the battery to keep it in memory.

In a car's ecu I'm guessing this would also hold true for any learned values but the stock maps would always still be hard coded into the rom chips which don't go away even with total power loss. The question is if the battery is disconnected would there be a back up bios like battery on the cars ecu and tcu to retain those learned values or not.
