Technical Proxi Allignment risk after chiptuning

[htevents]

Hello all,

I have a Fiat Punto 2012+ 1.3 MultiJet diesel car.

My car has it's DPF cleared out (the housing is still there, but the internal parts are gone). The regeneration process and sensors are disabled in the ECU, so I don't get any errors, etc. At the same time, I have my car remapped by a forum member of a dutch fiat forum (for some extra power). He had succesfully put remapped software in several cars of other members of that forum. The car runs fine (even better than before), but because of the mapping being from a different car, I suspect that the body computer of the original remapped car, didn't had cruise control enabled, because after the remap, my cruise control doesn't work anymore (I can't even activate the stalk/no message on the display and no cc light on dashboard). The strange thing is: the auto lock function (car locks when driving beyond a certain speed), didn't work before, but did work after the remap.

Are my thoughts correct that remapping the ECU with software from another car, can affect the body computer "settings" of my car so certain options are disabled and some other functions enabled, functions that where disabled before the remap, because of the used mapping?

If so, I have to enable the cruise control with Multiecuscan and then do a proxi allignment procedure.

If I make sure not to change anything else then the CC settings in MES, will the procedure change anything else or only what I change?

So what are the risks of doing a proxi allignment procedure after enabling the cc in my body computer, affecting disabled sensors, the disabled DPF regeneration process (because of the internals of the DPF being removed) and other function being disabled/enabled for the correct ECU map?


If something is not clear, please ask and I will try to explain in more detail. English is not my native language.

Thanks in advance for any help.

I would like to know about this problem as well.

In addition of my first post:

I connected my car to a licensed version of MultiEcuScan (MES) and found out about some things. First I see no error messages, so normaly that is a good sign.
I tested the clutch and brake switches (I have 2 for each pedal according to MES) and they respond well. But when I test my Cruise Control switches, nothing changes, as if the connection between the CC and my ECU isn't there. Strange because it was and should be there because it was functional before the remap.

In my Body Computer, MES reads that the "Cruise Control (from 2009)" and the "Cruise Control (until 2009) are both enabled.
Is there a fuse for the CC that could be blown, so the ECU doesn't receive any data from the CC?

I can do a proxi allignment procedure, but as I said in my first post, I don't know the risks and consequences of the procedure because of the "disabled" DPF and remap + I am worried about a new thing: the notes of MES states that the "Indicators Command" and the "Alarm Country Mode" will be set to the factory default values and I may need the 5 digit security code of my car, to be able to correct these settings. When and in what situation do I really need that security code?

Then something else: my car has the Blue and Me function + it has a windows logo (at the usb port and on a button on my steering wheel). If I connect to that module selecting the Marelli/Microsoft Blue and Me, MES syas the ISO detected the module as a Lauberhorn Blue and Me (without the microsoft). Can this be a result of the mapping being from another vehicel (a vehicel with an other body computer) or is this not related to the mapping of the ECU?

So with all the above info and questions, I am left with this:
- Can there be a blown fuse that stops the ECU from getting signals from the CC and if yes, where to find that fuse (manual doesn't help me there)?

- What are the risks/consequences of doing the proxi allignment procedure knowing my car has its DPF disabled and a remapped ECU (from another vehicle, that has the same ECU/Engine)?

- What are the risks/consequences of doing the proxi allignment procedure, needing the security code afterwards and don't knowing the code (can I get the code from a dealer or by reading the ECU with MES or something)?

- What else can it be causing my CC not working at all (the ECU sees no singals form the CC at all) after the remap.

It is really strange that after the remap, my CC has stopped working.

Please help.

Kick. I read about resetting the self learned functions of the car. Is that an option to do, even with the modifications that had been done on my car and in the ECU?

Hi.
Like you.. i would be a little wary of the relearn upsetting your 'amendments'

Does the Clutch switch still function?
Does the dash Icon still illuminate?? (Driven by MES...)

Both should be strong indicators of 'readiness'

I have 2 x 2007 mj grandes.. cruise is not supported by ECU

And 2012 ta punto.. where it is factory fit.

Clutch switch is functioning, also the brake switch is functioning (MES is reading pressed when pressed and released when released). The dash light of the CC is not lit. Not when starting and not when turning CC on. According to the ECU parameter page of MES, the ECU doesn't recieve any actions from the stalk. I can't manualy lit the dash light in the actuators page, so it seems like the remap made the ECU think there is no CC. I did a scan in MES and it sees a CAN line error (can be because I have an aftermarket radio installed).
So Proxi Alignment is an option, but what is the risk of that procedure with a remapped car with DPF removed and the risk of the resetting the self learned functions? Does the proxi alignment only connect the nodes or does it connect sensors (like the DPF sensor) too?

EDIT: can the EEPROM programming be a part of the issue?

EDIT 2: If I'm at the paramater page of the ECU in MES (key in ON position, engine off) and select the "Gear Engaged" parameter, I can put my car (a manual) in any gear, but it only reads neutral. Is that because my engine is of and I am not driving or is it the gear sensor? And if so, can the gear sensor be "disconnected" from the system due to the remap (with disconnected I mean, it has to relearn and is not broken) or is it really broken? If it is broken, it is a real coincidence that it has happen after the remap. The remap was the point of my CC to stop working.

I cannot help on the deeper info regarding the updates to mapping etc.

In my non fintional cc cars.

The MES says.. out of range.. when items are not fitted..

Do you have a different message?
Maybe yours is not in English.. so a translated message..??

 

[htevents]

Where does MES says out of range?

 

[varesecrazy]

Where does MES says out of range?

In Actuators.

Run cooling fan. Glow plug relay. Tank pump.

Then do dash icons..

Over temp. Low fuel. Cruise control

Aah, did that and no message. MES is just executing and probably thinking it is really illuminating. No error message at all trying whem executing. That is the strange thing. It feels like the ECU or Body Computer is just forgotten the cc. I do want to try proxi alignment, but not before someone can comfort me that it is a save procedure, even with the remapping and removed dpf. If I mess something up executing the procedure because of the modifications, I will certainly not perform the procedure. I am waiting for that answer haha.

I've seen something like this before
Not on a fiat but.
ECU remap was just. A generic remap file from a car that didn't have cruise control as as such when out on a car with cruise it wiped out all the information about it from the ECU guy had to get the car remapped again by a proper company

Hi,
It surprises me that you are asking us for help. You should be asking whoever did the re-map. It does sound like they may have just copied someone elses work without really knowing what they are doing. This is what happens when you do things on the cheap.

chris: I tought the body computer had to be CC enabled and will give the signals to the ECU by the canbus system. But to match all canbus modules, I have to do a proxi alignment. My initial question was if it is save to do that alignment because of the modifications to the car and ECU.
g8rpi: It was not because it was the cheap way, it was because it was offered and been done succesfull to other cars of members of that forum. Now I know better. The person who did the remap did try to help, but he didn't know the solution as well, so I went to this forum.

My main question still remains: is it save to do a proxi alignment procedure and/or reset the self learned functions of the car, with the modifications that are done?

Hi,
I can't say if it is safe to do a proxi-alignment or not as I don't know what the map has done. I do know however that the CC stalk signals connect directly to the engine ECU, not the body computer.
The CC is enabled by resetting the engine ECU self-learnt parameters and then operating the stalk switches. A proxi alignment is not required.

You shou also check the injector codes are correct if you have not done so already.

Which model engine ECU does your car have?

Thanks for helping me.

With the remap, a copy of the original map is saved on the guys pc together with the injector codes and sent to me by email. After the remap, he put back my injector codes.

About the car and ecu:

Car: Fiat Punto (latest model) 1.3 multijet 2012
ECU: Marelli 8F3
Dash: Lauberhorn (Blue & Me)
Body: Delphi (199) MY09

So you think it should be safe to reset the self learned functions of the car with the modifications in the ecu and dpf done?

 

[Rado77]

I think that Proxi alignment is about sync between all ECUs in the car - for example - when I want to connect MES to ABS ECU, I receive error measage on display "ABS unavailable, see handbook". After that I successfuly connect to ABS ECU and I can do anything I need. This error msg was, because Proxi alignemnt function hasn't been done - it's only sync between all control units

...

Did you find a fix yet?

 

[htevents]

No not yet, because I still don't have my answer if it is safe to do a proxi alignment and/or reset the self learned functions, knowing my dpf is removed.

 

[chris3234]

No not yet, because I still don't have my answer if it is safe to do a proxi alignment and/or reset the self learned functions, knowing my dpf is removed.

I don't think anyone will be able to answer this for you as your probably the first person here with these issues
