AK400 enhanced-AK500 
(Long-range upgrading of the network; more powerful; technologically more advanced) 
1; support for the key match of the Mercedes-Benz infrared "Keylsee go" function; 
2; support of Mercedes-Benz EIS + ESL + ESM key end-of-life recovery, a global leader in technology; 
3; support the 1995-1998 Mercedes-Benz DAS diagnosis I read and write data security, online unlock locked infrared systems; 
4;support of Mercedes-Benz E and C Department, Department of ESL online to read and write, without the demolition of ESL; 
5; support ECU Mercedes-Benz of FLASH (29F400 and 29F800) to generate the key data directly, without Renew FLASH, there was no need to program ECU, the world's leading technology; 
6;the MCU do not need to choose the type of EIS; into EIS data, equipment will automatically identify the type of MCU. HC705 the MCU data, the software will automatically prompt "HC705 into another of the EIS data" 
7; Powerful Motorola Microcontroller Programmer features: Motorola free to read and write down single-chip EEPROM and FLASH (912,9 S12, 9S12X series), also support the Mercedes-Benz / BMW / Volkswagen Audi engine computer, such as MPC (MPC555/556.MPC561 / 562, MPC563/564, etc.) and plug-in FLASH (MB58BW016, 29BL802C, AM29BDD160, DE28F800, etc.) free to read and write down, a car maintenance computer programming; vehicle transfer forms and the advanced tools to match the key. 

Follow-up to upgrade: 
1; Benz (R or W220) and 722.9 shift module ISM computers running gear grant Right. 
2; upgrade to read and write ESM Online EEPROM.
