Puma 2.4 is limited to 82mph and the 2.2 is limited to 90mph as standard from the factory.
Other options were available to fleet users or anyone wishing to have a lower top speed. https://bellautoservices.co.uk/store/puma-...er-remove/ |

Makes sense as the 2.2 has certainly exceeded 80 on a private road test

Hey Cookey95, I'm very interested have dumped my hex of my 2007 TDCI recently and was using ECM Titanium to try and get at the settings etc.. But, the definitions of the maps are weak at best. Where did you get you map definitions for WinOLS? I am not very familiar with WinOLS but have downloaded a trial of it an it doesnt seem to find the Visteon checksum on the web.
Help would be appreciated to get me up to speed with WinOLS. I am keen to do some map development and mods. I have some engine mapping experience but not on aftermarket software. I am sure you can make the EGR map 0 but you might get a airflow PID error code since the MAF would go out of spec ... need to find the value/table which would trigger that error. But you might get away with it. If you block the EGR and dont get an error you are free and clear and then that scenario would work. Also this will probably keep the cleaning cycle of the EGR active which can be good as long as it does not block open in the cleaning cycle. |

I was able to change the EGR map so that it remains closed at all times and also remove the codes. I intend to make a new thread and walk through the steps with another truck. Simple. Will take me a week or so to produce given work load right now.

Hi,
I am also very interested in learning how to deactivate the EGR. I just had to replace the EGR again after 2 years. 
Did you already post your tutorial or comments somewhere? Can you tell me the link? Best, Elmar |

Hi all, Have anyone tried to read DCU106 as DCU102 in KESS? There is only protocol for DCU102 in my version.

The dcu106 and dcu102 use the same family

Hi, nice to hear. Have you successfully read/write via OBD with KESS V2?

I do not use kess, but as I have mentioned it belongs to the same family and both the dcu102 and the 106 use the same protocols, in principle you should not have any problem reading and writing if the Checksum in writing corrects you

Hi all!
Super interested in this. To begin with - what hardware and software did you use to get the ECU maps dumped to a file? Was it done using the OBD port? BTW - I have a 2012 2.4 TDCI 130. Thanks. |

Afternoon All,
I've had a few IMs about this so I just thought id clarify how I solved it. This is not a tutorial on how to read vehicle maps, and use industry standard software for mapping etc. You can find basic tutorials on YouTube if needed. In short, KESS V2 units can be acquired from your favourite venders. Those of Chinese decent often come with a handy CD that includes any required software to pull the vehicle Hex file off the engine ECU via the OBD port. You can then use WinOLS to open the Hex file to view and edit the map data. OLS files are essentially keys to the hex data that translate the hex dump into English to show you where the data sits within the hex. They are generated by people reverse engineering the hex file and often kept close to people chest but you can purchase them online sometimes. In my experience, the map data and map locations seems to vary depending on what ECU and SW version you have, so with that in mind it takes a bit of investigating to ensure you are are editing the correct value within the hex and it usually wont be in the exact same spot from one vehicle to the next. In short, once you pull the map off of the vehicle and open it in WinOLS, you can use the ols file to help identify the included map data within the Hex file. https://www.dropbox.com/scl/fi/dwbbbcef5ph...f&dl=0 The EGR is controlled by a PWM signal. 0% Duty cycle = closed, 100% = fully open. Look for a value called "EGR Valve DMD Multiplier". By default this will be set to 1. If you change this to 0, all EGR demand signals from the engine ECU and multiplied by 0, which sets the PWM demand for the EGR to 0% under all conditions. Its as easy as that. You don't have to worry about Engine MIL lights etc since the engine is always expecting the EGR to remain closed. I actually had a sticky EGR value that would trigger a MIL light on occasion and throw the car into LIMP mode and after setting the EGR to 0, I never had the issue again. Once you have edited the hex, you use the KESS unit you reflash it back onto the ECU via the OBD port. This solution only applies to PUMA vehicles as far as I'm aware. |
