ECU Chip Tuning Tool / November 1, 2019

04-10-2019 update: Trying to clone Mercedes sl500 ME2.8 ecu and everything goes fine until the end when writing eeprom it gives error..   04-10-2019, 19:21 PM update: One friend suggested: Swap eeproms. Or do it with eeprom programmer like UPA. So just clone flash with ktag. Clone ktag have this issue with that ecu. Ori works perfectly.   Another friend agreed:  Absolutely right… I have done the very same car with upa and didn’t do the flash but hw and sw numbers of ecu were the same.   05-10-2019 update: After cloning was complete I examined files before and after clone with HxD editor and mpc file was identical also was maps, then examined eeprom file and vin was written in almost the complete file was the same except for a few scattered digits maybe 10 or so in the whole file, so wondering if this is just a false error, haven’t been able to try ecu in car yet after clone, will report how car reacts to clone ecu….   One friend shared his experience on 08-10-2019: Ktag 6.070 under Trasdata working like a charm on this ECU. R/W e2p/mpc/ext with no problems. 6.070, 7.020 under Ksuite never work….

Ktag V7.020 Car Protocols Gray Buttons Solution
ECU Chip Tuning Tool / September 17, 2019

Offer working solution to Ktag 7.020 error “ any car protocols its gray buttons”, can’t select or choose any cars . ktag v7.020 does communicate between laptop and ktag device and can select cars/trucks/….etc It does have power.   Possible reason and solution: connect 12v adapter.   The problem is in the SD CARD that is in the interface. I had the same problem and solved it. Programming the sd card for KTAG and KESS is a very difficult process that cannot be done by everyone. There are two options 1. that somebody who knows, do – can program a new sd card or other option to buy SD CARD.   or the problem is with nxp. Here is NXP chip sold in China.   Last but not least, ensure you have one good quality of Ktag clone. i.e SE135-B1 (73.39euro, red pcb), SE135-E (63.22euro, red pcb).   www.obdiitool.co.uk
