IDS PIC

 

[irondoor19]

I did an IDS session for a 2010 Taurus SHO and there are programmable settings for Tire Size and Gear Ratio for the PCM.  I would check those to make sure they are correct for your vehicle and still not set at the donor vehicle.

By ECU you do mean PCM correct?

yes we mean PCM.....

Def make sure the tire/speed related settings available in iDS match your vehicle then and not the donor.  Calibration of the IPC firmware isn't going to fix a mismatch for that.

SOO i make an assumption that this is Dealer Only... We yelled at them Enough, They
Said: Bring it in....Leave it for a Day.... We will Get to it... AND this was after the Service
Writer, the Chief Mech, and the Floor Cleaner (ALL SAID, We must have screwed it up)
SO We yelled at the Parts Manager (The Guy that SOLD me the Engine, ETC 5K worth)...

I thought it could be set by tuning devices as well.  Maybe not at the enduser level, but certainly by the person/company tuning it?

Well Then I will Check w the Tuner, When we get the SCT back..anything is better
than dealing with the Dealer (my head hurts)....

That's what I don't understand about dealers....you have an issue with work they did and yet they are rude to you.  Its perfectly fine to ask questions about what they did or didn't do.  Especially when you spent that much money.

Those are settings that should have been verified before releasing it back to the customer.  The reply should be we set/checked those settings or no we did not verify that, bring it in and we will quick hook up and check.

I would show them the screen shot that JMR posted make sure those are correct first..Something is weird that it is off initially.I would want it correct when the car is stock right?...I feel like trying to fix it with a tune is not the right thing to do...No reason it shouldn't be correct at this moment

So you are saying a tuner can't change these values in the PCM?  Or the tuner can only "mask" the PCM values?  Then yeah, the dealer, or a shop that runs IDS, is the only resort.

 

[irondoor19]

OK:

so the dealer gave it a go... NO Dice.. The computer will not allow the changes to be made,
the system is smart enough to lock out any change, conflict between brains, so the ECU must
be from an identical car, otherwise FU.... Back to the drawing board, and Prob back to swapping ECU's...
and another round of flashing...YIKES

 

[jmr061]

I am not sure I follow.  Hooking the vehicle and reading it with IDS would populate the fields shown with whatever values were there.  Were they correct or were they wrong.  If they were wrong and the correct values for your vehicle refused to write there is a situation described in the vehicle information available to the dealer via OASIS in which this will occur.  The PCM only allows these values to be written a limited amount of times before it requires a full reflash.

Do you have the VIN of the vehicle it came from?  If you do I can tell you what those values are as it left the factory.

At this stage of the Game We are at the Mercy of the DEALER..

I do have the original ECU for the 2011, (installed in the 2010) and
ON Tuesday we will see if we have the currently installed 2011 ECU VIN...

this whole thing got jumbled (my fault), and we have been thru 2 Dealers to get to this point..

I will get this Pile of ^%$* solved...AND if shoveling money at it is what i have to do

SO BE IT..

I think you should let Jason sort it out for you, frankly.  At least that way you have an EXPERT looking at the problem!
