drum_buster Posted January 12 Share Posted January 12 Looking for anyone that has experience or confirmation of changing the tire size settings in a Gen1 Transit connect. Specifically a 2013, US version. I understand it should be in theory possible with the lastest forscan software with custom circumference, but I have only read about other users successful doing so within the context of the later year TCs. Thanks, Quote Link to comment Share on other sites More sharing options...
drum_buster Posted Thursday at 10:32 PM Author Share Posted Thursday at 10:32 PM Still searching for answers here: If anyone in UK has a gen 1 Transit Connect or Tourneo, and can use forscan to send me a screenshot of your IC, VSM, and GEM As Built, as well as your factory tire size, that would be appreciated. I'm having AI reverse engineer to identify if any of these as built data corresponds. Quote Link to comment Share on other sites More sharing options...
windguy Posted Saturday at 05:41 PM Share Posted Saturday at 05:41 PM @drum_buster Just some random thoughts to help get your question answered. Have you tried posting your question on the FORSCAN forum? I have a Gen2 TC. I'm vaguely aware that the TC shares some similarities to the Ford Focus. Not sure about the Gen1 TC, but perhaps that too is similar to the Focus or another Ford model. If so, perhaps there's a Focus forum you can post your question on as well. Keep us posted. Good luck!

drum_buster Posted 1 hour ago Author Share Posted 1 hour ago (edited) @windguy Great suggestions, I have not gotten that far due to time. I do have some clues - and i'll share an abridged update on findings thus far: I am going to be painfully clear on van model/etc for clarity for all future readers Gen2 TC is somehwat well documented elsewhere in this forum and Forscan forums on selecting/modifying screen menues as well as manual modificatino of as-built wheel size data. I've read extensively on that. I've used Forscan on my Gen1, there is no immediate tire size selection. Further, as as far as I can tell, As-built data is not revealing any obviuos lines of hex data that would correspond to a wheel size. I believe the wheel size data, or revolutions/mile data for speedo is stored in PCM in Gen1 TC. Forscan (thus far from my experiernce) cannot read PCM on Gen1 TC. Hoping maybe i'm doing something wrong. PCM on my van (2013 United States), according to Chat GPT across broad cross searching, is the same make PCM used in 2010/2011 Focus. I've also learned perhaps the software ELMconfig can read PCM data, but I have yet to find a reliable download source for this software to try it. Also, there is vague reference that my AI has found that suggests a Ford Dealer may be able to read/write PCM module from Ford Focus 2010/2011, and thus might translate to being able to the same my 13 TC Gen1. I haven't gotten further on this lead. My ask above for someone else to corrobrate their data from their van (from a non US variant) is an a third parallel effort to help my AI run a comparison (since UK variants had a different standard wheel size) to see if that could narrow down information from the other readable modules (ABS, IC, BCM, VSM) modules that might correspond to wheel size. Again, for Gen1 TC. Well aware Gen2 TC this data is readable and accessible in at least 1-2 locations. More to update hopefully soon....
