Defender
If VIN prior to 2A622423 then ECU is MSB type (OTP, non-flashable)
If VIN post 2A622424 then ECU is NNN type (flashable)

Discovery (Manual or Auto)
If VIN prior to 2A736339 then ECU is MSB type (OTP, non-flashable)
If VIN post 2A736340 then ECU is NNN type (flashable)

'tis the dark arts for sure......begone thee evil one.....

Ok....to the less informed, technophobes like myself, what, and where is the AAP?

It seems that if you want to do this the proper way and get the best value for your upgrades, then doing the whole thing is best.

Cheers all.

At the risk of coming across a bit pedantic... shouldn't it be NNN000120 instead of NNN500120?

If looking for an upgrade - I need to stick to an EU2 based program.

Or, If I go for an EU3 program I need to upgrade a sensor (AAP?? not sure what this is, but will Google it) and get a new throttle pedal. Is that correct?

Thanks

The Ambient Air Pressure sensor, it's in your airbox, they are not cheap either, stick with the EU2 file, it will work out much cheaper.

Good advice

Updating the older D2's to the 3-track accelerator and 4-wire AAP probably adds $200-400 to the cost of doing an upgrade.

After a bit of investigation I think the 3-track pedal is actually plug and play. Despite the indications of the 2000MY wiring diagrams that a wire was missing, the all the connections actually seem to be in place. Second hand pedal: $60.00

The 4-wire AAP requires using a different version of the air box lid - they are £29.00 new so pointless getting robbed by wreckers on this (it's a bit like the battery cover which is cheaper to buy genuine from local parts suppliers than from the wreckers). The 4-wire sensor is about half the price of the 3-wire version if you buy genuine. Halve that again if you buy the Mini part.

The 4-pin connector Jose linked to is available locally at comparable cost but has a MOQ of 5 pieces. I'll have four spare if anyone is looking for one.

I'll buy a couple from you Paul

I must thank Offtrack for posting this information, I'm printing it out and will spend some time trying to get an understanding of the subject, if only to get a basic idea in how the system works. So, thanks, Offtrack, for getting my tired old brain creaking into life, [ it's all those rusted cogs] Bob
