  1. Can't connect OBD2 to ECUs for Car Scanner

    I have a 2021 AWD ER premium Job 1. I have 2 OBD2 Vgate adapters, one for Bluetooth LE, and an older one for WiFi. My OBD2 adapters and apps used to work; I had not used them for a while, then they stopped connecting to ECU. The adapters do connect to ELM327 either over BTLE or WiFi, but not...
  2. Calibration change info in EPA 2023 certification docs

    These docs from https://dis.epa.gov/otaqpub/ (which I have posted about in the past but not recently) often contain quite a bit of information, and are somewhat hard to decode and understand. As is often done, the (zero emissions) certification of newer models is based on the testing of previous...

  4. Mach-E GT acceleration modeling shows possible performance capability of the GT

    I applied an acceleration model similar to the one for RWD and AWD ER https://www.macheforum.com/site/threads/mach-e-extended-range-acceleration-modeling.2177/ to the Mach E GT (base) with the limited info available. See the attached pdf for details. Many approximations, no fudging or tuning...
  5. Mach-E GT and GT PE window stickers with fuel economy?

    The GT and GT PE are not yet listed on fueleconomy.gov (which is unusual since they are being sold). Can someone post a window sticker for each model? Both models are listed in the Aug 25 release of the EPA 2021 test car list data...
  6. New EPA data posted for Mach-E models

    EPA has updated the test car list data for 2021 models, https://www.epa.gov/compliance-and-fuel-economy-data/data-cars-used-testing-fuel-economy and now lists each of the RWD, AWD, SR and ER including the Cali Rt 1 model. This data has the unadjusted MPGe for city (UDDS) and HwFET cycles, and...
  7. Mach-E Extended Range Battery buffers and DCFC limits

    The plot shows the estimated open circuit voltage and the battery terminal voltage for 100 and 400 A current for both charge (+) and discharge (-). The Voc curve model is estimated for Li-Ion (NMC?). The internal resistance Rint is also estimated based on scaling from similar cells. Rint is...
  8. Mach-E Highway and City range estimates from Window Sticker Label

    MPGe is AC energy from the grid to recharge the vehicle including parasitic energy losses, and is based on 33.7 AC kWh/Gal equiv. Range is determined by the DC energy available from the battery system (also including other vehicle parasitic power demands). The relationship between the battery DC...
  9. Mach-E Extended Range -- acceleration modeling

    I put together a pretty basic acceleration model and was able to match the Ford target of 0-60 mph with 1 ft roll out by adjusting the test mass just slightly. See attached. The modeling of a higher performance GT model gets a bit tricky due to traction and traction control. Has the curb...
  10. Mileage for Extended Range Mach-E Models Revealed in EPA Emissions Certifications

    All vehicles have emissions certification posted by EPA, even zero emissions vehicles. Today I finally found the Mach-E certificate summary information (CSI) posted (see links below). There are two Mach-E vehicles posted; AWD ER and RWD ER. This data is the unadjusted City/UDDS and...
