Your boot pin ......

I wll try...are u sure only this pin for boot not need resistance and what programmer can read?

[zmann]

Depends on the resistor on the track in the photo (unclear). For more precise I would power up the ECU... measure the voltage at the boot point, together with the known value of that resistor then should be able to rekon the pull-down resistor that can bring the boot pin to low. You may try following other typical FGT photos. If your FGT worked on others Tricore ECU's and your CAN pins are correct it should work on here too. TC1766 needs only one.

Thanks for reply
Pls show to me how to measure boot and. How to know resistance where can connected resistance
I hop reply

Read and tell me the value of the resistor (I think it is, unclear photo) near the boot pad.

OK 100 ohm

You didn't measure the voltage, and 100 Ohm is quite low. So for safety reason just tempolarily remove the R and pull down the boot point as shown on the image.

ps1. Sound like you haven't yet played with FGT. To those typical engine ECU's there are two +v pins, one is usually Vbatt another is Vignition which FGT usually connect it with his wire 'igniction'. This gear ECU may be fed a bit differently. Anyway try to feed it by the two pins as on your photo and proceed.

ps2. Why you need to read Tricore? I just feel that the Tricore is not the master MCU. The main program should be memorised in flash S29CD016 and worked under MPC. Why not read the MPC if need to do something with the program, but I may be wrong!

Thanks for helping
I read tricore because I need read flash gearbox I can not read flash gearbox from main mpc because I read MPC and only read eeprom and flash engine

If I put resistance between boot pint and other point necessary to connect wire Gray for boot?

[zmann]

Oh Yes, with the R no use grey wire but you can try both ways, the R is same function.

Above, are you saying that this ECU is integrated function, two in one, of egine + transmission?

ps. I don't used skype.

Hi
I try but not read I want to read I need help
