To reflash the GEN1 TCU to our MaxxECU custom Dodge TCU firmware, you need to use a TCU reflash tool (product ID: 2277) which are able to reflash the whole memory area, not only the "maps" area, which most tool only are able to do.
Note: We never got their PC software to work, but the app works fine, so don't bother trying to get the PC software up and running.
How to reflash the GEN1 TCU to MaxxECU custom Dodge.
1 - Hardware setup
1. Bring out the tool, cables, adapters and connectors from the package.
1.2. Insert the DB15-LAN cable into the ACDP-II tool, make sure to check the switch to be set to CAN-R.
1.3. Power the tool with the included AC adapter, insert the provided USB-cable that fits your phone, connect the high speed data cable with the gearbox TCU connector and the DB15-LAN connector as the image shows.
1.4. Gently insert the ACDP TCU connector into the ZF TCU connector, pay attention to the guides as there is only one rotation angle it can be inserted into, make sure to seat it all the way in using a little bit of force.
2 - Software installation
2.1. Search for "Mini ACDP" in app/play store, download and install.
2.2. Allow the app for read and write access.
2.3. Select the ACDP-II from the list, since that is the tool you have.
2.4. If the app language is Chinese and you don't understand a clue, change to English :). Third option from the top in settings.
3 - Module registration
The 8HP interface board and programming module needs to be registered before the first time use.
Note: if borrowing/lending from someone used to program their 8HP, you most likely wont need todo anything here.
3.1. Tap on "Me" and then "Module list" to see authorized devices and modules.
The module list should look something like this when everything is good, so if it does, you can skip to the next section.
Peel of the green sticker to access the authorization code.
The authorization code that needs to be entered if module not authorized.
Press "ADD" if you need to add a new module that does not exist in the list, follow the onscreen instructions to complete.
4 - Flashing
Download the latest firmware files for your 8HP gearbox:
The 8HP control is not yet released, we are currently in BETA stage, no files here to download yet for public use.
8HP70 latest files
MaxxECU_Dodge_8HP70_custom_internal_flash_002.zip
MaxxECU_Dodge_8HP70_custom_maps_002.zip
MaxxECU_Dodge_8HP70_custom_EEPROM_002.zip
Note: do NOT try to use any of these code/calibrations together with OE Dodge or any other ECU/PCM; it will not work and might trash your gearbox. ONLY for MaxxECU EMS.
Save the internal flash, maps and eeprom files (for your gearbox model) on your phone and unpack to the Yanhuaa folder you gave the app access to using the phone file-manager in the beginning.
Flashing order (IMPORTANT)
1.Internal Flash.
2.Maps.
3.INT EEPROM.
4.1. Tap on BMW.
4.2. Tap on EGS.
4.3. Tap on "8HP Clone"
4.4. The steps to make, always start with the identification to make sure you have a good connection with the TCU. Secondly always read the internal flash, maps and eeprom memory, incase something is happening or if we encounter an ECU we have not seen before.
Identification example
4.4.1. Example of identification (always take a screen-shot of this data), make sure the Bosch part number is supported, see 8HP hardware identifier.
Note: if your TCU is on the list of supported models, it does not mean you are smoked, just that we have not seen or verified that part number. Please contact us if not in the list, good or bad so that we can update the list and try to help you out.
Read Maps Example
4.4.2. Press the "READ Maps" and follow the on-screen instructions and save the file to phone.
Write internal flash example
4.4.3. Press the "Write INT FLASH", follow on-screen instructions and select our custom files you downloaded in step 4.
Flashing order (IMPORTANT)
4.Internal Flash.
5.Maps.
6.INT EEPROM.
Flash process is now completed.
