TVR E6549 MC
Engine management ECU memory chip
Memory chip for TVR MBE engine management ECUs. This is the memory chip for all the MBE engine management ECUs as fitted to many TVRs. There are 2 replaceable chips within these ECUs, one is the ROM with the tuning program and this one, the memory chip. This non volatile SRAM carries the "service tune" settings and other variable information and this information is maintained by the internal battery within this memory chip. This battery can and does fail eventually and causes this stored information to be lost which can cause many varying symptoms with the management and running of the engine. Replacing this chip and resetting the "service" tuning parameters restores the basic settings and brings the chip into operation.
