If youre getting it mapped you really should have a vehicle specific map. All cars are different and require different tuning.
Otherwise you've just got a generic map that generally just dumps extra fuel or wont be specifically suited to your vehicle. |

Disco and Defender MSBnnnnnn ECUs aren't interchangeable between the 2 models.
The later Flash NNN prefix ECUs are/were/supposed to be generic.  1988 90 Td5 NAS soft top

Martin,
I was told that, but why? does it have to do with engine specs? Injectors? Weight? Its kinda unfair that our msb chips are 250gbp + and the discos are 60gbp... |

Different engine map on the Disco, plus it drives the dash slightly differently (backwards temperature gauge).
The MSB ECUs are not programmable in the same way as the NNN, the NNN is the later version which is programmable for the vehicle type. 1988 90 Td5 NAS soft top

Any TD5 ECU will "run" aby TD5 engine, at least to go home slowly. Difference between Defender and Discovery is different gas pedal and temperature gauge working in opposite way. The problem is the gas pedal, when you use Discovery ECU in Defender, it works like on/off switch instead off smooth linear change off power.
Second difference is Euro2 (10p) and Euro3 (15p) type of engine. And last big difference is type od gearbox. ECU for auto gearbox has some circuits for CAN bus and missing parts for clutch pedal sense. "Drobek" = The Small One - Discovery 2, "BlufÃnek" = The Blue Thing - Defender 130, and for me at least Ford Mondeo  |

Ok, makes sense
Ok so where may i find a msb evu with dual map options? I read that if a ground is activated it switches the throttle response to be a bit slower and not so sudden. |

I find funny when ppl try and play me for the fool.
The 60£ chip guy on ebay changed his story where the chip will work no problem. I sent him a copy of his disclaimer where it wouldnt work, and he said he has to post that... |

TD5 ecu has two sets of maps - one for high range and one for low. The main difference is in gas pedal response - in low range there is applied some filtering to smooth the response in harsh environment when the driver is shaked in car.
I have no experience with MSB dual map ECU - it is a bit unpractical for me. I have upgraded some NNN ecus for dual map - changed the main memory for a bigger one and added switching circuits. It is possible to do live-switch with running engine. I have standard map and a tune one, and when switched in running car, it is like one gear down. Instant power. Main use is for testing remaps, showing the difference or for those, who share the car wit other users, not experienced how to use powerful car on road (driving 150km/h in Defender for long time is not the best idea). "Drobek" = The Small One - Discovery 2, "BlufÃnek" = The Blue Thing - Defender 130, and for me at least Ford Mondeo |
