So the chip in the lower left with 'AM29bl....' is our flash memory, according to the datasheet for it this is the 8MB chip. The larger chip with 'TriCore' is the main MCU/CPU - and is quite a capable little chip for an econo-box. This is TOP shelf stuff in the EMS world! The 'Delphi' chip with a 466 on it is most likely the memory management/watchdog chip. (only speculation at this point on the Delphi chip) The others are just voltage regulators/filters, some DC motor driver(s), injector drivers, and other ancillary stuff we need.

FWIW: there are open source tools, and an RTOS 'OS' available that has been ported to the tricore 32-bit. see www.hightec-rt.com for the scoop. The GCC tool-chain is Eclipse ready and slaps right in. So make note, the entire chain of tools is available in the open source flavors to individuals for learning or reworking your own rig.

I am a technician, trying to replace an ecu on 2008 Aveo, the old ecu has mark on it as KN, MT34 and this car is manual transmission.

i got a used ecu from the junk yard place it on the car, performed online sps to it, now got tech2 perform 2 key relearn function, cycle the key 3 times after the 10 minutes count down reached, but I got failed programming message on the tech2,

but it when I check the key diagnosis, I have key status ID 1 learned in the immobilizer, I checked the second key and it was also learned but the ECU is in UNLEARN status... pls how can I learn this ecu so that the status can appear learned ...

i have performer 30 minutes relearned but did not still work, the ecu is still in the UNlearned status,

11 minutes on and then 10 seconds off, 3 times but ecu won't go into learn status in the immobilizer.. I need idea how to go about this... or is there a chip to transfer from the damaged ecu to the used one I got..

rememver the damage ecu starts alright with the ecu being in Learned status but the throttle side is not functional, as you press the pedal but the junk yard one has the throttle working as you press the pedal you see the to reading
