Bosch M797 (+) / Kefico
You can read this ECU Also by KTAG
Read / Write FLASH
read / write the EEPROM / ECU (only ECU Bosch M797 and M797 +)
read / write the EEPROM / ECU (only ECU Bosch M797 and M797 +)
File Size firmware to FLASH memory:
Bosch M797 - 512 kB (524288 bytes), EEPROM memory - 512 bytes.
Bosch M797 + - 832 KB (851,968 bytes) of memory EEPROM - 512 bytes.
Due to the fact that the computer Kefico, Establishing cars KIA / HYUNDAI, as well as ECU M797, on Chery vehicles, schematic of Geely are very similar to Bosch M797, reprogramming these control units similar to reprogramming the ECU Bosch M797.
Attention!
Blocks Bosch M797 and Bosch M797 + are hardware differences. The difference is that the processor used Bosch M797 C167 with the external flash memory type AM29Fxxx, and Bosch M797 + no external flash memory and the processor also applied - ST10 with internal flash memory for storing .
Obratite also note the symbol "plus" conditional, and only in order to highlight the differences in hardware computer data. On blocks sticker symbol "plus" is missing. Those. for Bosch M797 + will be written on the sticker Bosch M797.

Revision Bosch M797 (Kefico).
For transfer to ECU reprogramming mode has two options:
1. You need to solder the two SMD resistor 5-8KOM as shown in the figure.
2. With the help of a homemade probe with a clamp "crocodile" jumper O processor 104 to ground through a current limiting resistor to ground 4-8KOm order to supply to the computer power supply. As the weight you cann't use the bus for ECU PCB perimeter of the circuit board.
Next, hold the probe, it is necessary to apply voltage to the ECU and 2-3 seconds, remove the dipstick. Now the computer is in a mode prepared for the programming.
It should also draw your attention that the CPU 104 are connected by a foot is always one of the flash memory feet (usually a 24 foot flushes). In this connection it is advisable to connect the probe to the foot of the memory chip.

Revision Bosch M797 +
To put this in the reprogramming block mode has two options:
1. You need to solder a SMD resistor 6 KOhm order as seen in the figure below (designated as R). After reprogramming remove resistor is not needed. Also removed at the time of reprogramming resistor (which is indicated by a cross in the photo), after the reprogramming is required to solder it into place.
Bosch ME 7.9.7
Since the inside of this unit is very strongly reminiscent of ECU Bosch M797, just as the memory chip FLASH AM29F800BB used memory, the read-write this block need to use the loader tab Bosch ME 7.1 / 7.5.
for read-write operations on a table similar to the pin-ECU Bosch M7.9.7.
Connecting to a computer terminal on the table
51.53 - gnd
71 - K-Line
13 - Ignition (+12)
12 - continuous voltage supply (+ 12V)
43 - Programming Mode Resolution (gnd)
44.63 - Power of the main relay (+ 12V)
When programming programmer PBB 2 to transfer the programming mode Put the switch on the 81 pin connector in position "II".
