MERLINS RALLIART & EVOLUTION-X TUNING GUIDE1.11-ECU OPERATIONSThere are four ECU operations that can be selected:Read from ECU – Reads the ECU (all of the flash-ROM) into EcuFLASH.Write to ECU – Writes the whole of a binary/hex file to the ECU flash-ROM, thenchecks the write was good.Test Write to ECU – Uploads the flashing kernel to the ECUs read/write memory(RAM) and sends data blocks to the RAM, thus confirming communications to theECU. Flash-ROM, where the ECU routines, data tables and maps reside is notwritten to or changed.Compare to ECU – Compares the ECU flash-ROM to the ROM currently select inEcuFLASH.Assuming you want to proceed and read the ECU, turn the ignition key to RUN (notSTART!). Click on the Read from ECU function and then select the type of vehicletype to read. On earlier versions of EcuFLASH, this read window could come upblank with no vehicle type to select. If this happens, close the application and copythe contents of the “read templates” folder into your ROM directory and thenEcuFLASH will find the files it wants.EcuFLASH will now proceed to download the ROM image from your ECU. When theread operation is completed, EcuFLASH will attempt to access the ROM, by readingthe ROM identity code. If there is a matching XML definition file available in theselected mettadata directory, EcuFLASH will open the XML definition file and theROMs contents can be examined with the menu bar.Save the ROM now, use your own name or something you wont forget or lose. Thisis your base ROM file, from which all your on-going tuning will be derived. I wouldstructure ROM labels in a uniform way so they will automatically stay organized inthe ROM folder and it is easy to keep track of which is the latest version/mod. Somy ROM files will typically look like the following:88590013_logic_01.hexThe first 8 digits are the ROM identifier, the second group is a name tag for whoseROM it came from, and the last two digits are the version/iteration/mod level. I use_00 as a base un-modified example for that ROM type, _01 for the first read andsave for a clients ROM, thus ensuring his immobilizer code is not lost or obliterated.Subsequent tune versions get incremental numbers. Windows will thus keep allrelated files grouped and organized.REV: 0.K merlin@three.com.au Page 20 of 134
MERLINS RALLIART & EVOLUTION-X TUNING GUIDE1.12-ECU READ FAILED or CANNOT CONNECTThere are several possible problems that may arise when first time connecting:1. Grey Up-Load Icon - Nothing happens when you click on the Up-Load Icon, thisis EcuFLASH indicating there is no OBD-II cable detected. Check the cable isconnected properly. If it remains grey, the cable is faulty, or there is no 12 voltsupply to pin 16 of the OBD-II connector.2. Blank Vehicle Read Selection Window – EcuFLASH is looking for the vehicle“read template” in the wrong location or folder. The program can sometimes get itsknickers in a knot over this, I don’t know why.Close EcuFLASH, open the directory tree with Explorer. Find the read templatesfolder. Copy the read templates folder into the ROM folder. If it still comes up blank,copy the template xml files directly into the ROM folder.REV: 0.K merlin@three.com.au Page 21 of 134
