Convert from M7.9.7 to ME7.9.7.1 ECU

Postby ThekeyMan » Wed Feb 25, 2026 6:39 pm

Hi there

Hope somebody has a solution.
The old ecu is M7.9.7 which has C167 MCU and EXT FLASH AM29F400BB + ST95080.
Because these ECU are becoming too old and difficult to find in working condition at good price we found that a new revised version exists which is the ME7.9.7.1 which seems like ti could work because plugs and pinouts seems to be the same.
However we now have a problem because the newer ECU have ST10F275 + ST95080 which has built-in memory. So basically the Operating system and Maps are all in one file whereas the old has EXT on the AM29F400BB.


So I would like to know if there is any professional out that that could assist with this and we willing to pay for a proper working solution.
Somehow copy the maps from the old ECU to the New ECU and make it work with the new ECU. If we can disable immo (as I see many chinese cars using ME7.9.7.1 can be immo off) then it would be good.
Let me know if this is possible and how to go about it or if you can do it and I will pay you for it.


Thanks alot
