Old thread, but does anyone know what is the torque limit from AL1000 0C8927750H 1885? It´s for 2012 Touareg with CASA engine 176kw 550NM. Attached Winols FRF -> BIN file, it´s data part only.

In fact blocks in FRF for these TCU are not crypted, so it "should" be possible to modify FRF/ODX, calculate checksum (OLS817) and flash it with standard tools.

Does anyone know if these tcu have some kind of protection / RSA which tuning tools bypass before writing calibration? TCU is outside from gearbox and very cheap at ebay. Someone knows what is inside?

Since i was asked in PM about these tcu controllers. There is a SH7058 in AL750 and SH7059 in AL1000. SH7058 can be read even with some Fgtech clone or i think with some other clone tools for these mcu. I bought xprog from eldb with authorization for these Renesas SuperH: http://www.eldb.eu/index.php?route=product/product&path=35&product_id=87 There is also a pinout online for AL750. To make it short, it was waste of money, support is not existant, i think SH7059 will never work. Anyway SGO from AL750 (some does not exist, e.g. the Q7 BTR from a friend) and FRF from AL1000 can be unpacked straight forward since they are not compressed or crypted, checksum can be done with OLS817. Signing from SGO / ODX is also no problem because it´s only the checksum result. Some newer AL1000 tcu has compressed FRF, this will make it a little bit more complicated. Anyway did not found informations about AISIN maps, my friend lost his driver license, so for now i canceled this...
