Since i got nanocom i thought id have a look into mapping, Says my ecu is not programmable.

Anyone know anything about the programmable ecu's what type they are etc?
 
Programmable ecu's were fitted from 2002 onwards. You either have to buy a newer ecu which will be approx £200 upwards, then buy or get a map for the nano and then write it to the newer ecu. It is also better to get the same gear stick option as your current car.

I think the numbers are NNN000130/NNN500030 for an auto and NNN000120/NNN500020/NNN500250 for a manual.

Or just pay about £250 for your own ecu to be remapped where they will change the ecu chip for a programmable one.

Is the process of making a non-programmable ECU programmable simply the art of replacing the PROM with an EEPROM, or is there far more to it than that?
 
it might be worth while gettin hold of alivetuning.com/td5 alive there based in grimsby i believe think they do a remap for around £400 all in
 
Nathan, the easiest thing to do is phone Gary at Alive Tuning he will be able to explain the work and cost's involved. When I got my 04 Disco remapped he showed me a jar full of old chips he tookout of the older ECU's, he does those things in his sleep.

Hi Nathan, the issue is all about "flashable" ECU's. This means that via the OBD socket tuning equipment can access the engine ecu and and alter the parameters or 'Map.

Flashable ecu's were std from euro 3 engines onwards. This in practice means engines and D2's built after approx mid 2001. I had a pre-facelift car which had a euro3 engine which was flashable.

To check to see if this applies to yours you need to check the reference label on the ECU itself. From memory if it starts with NNN it's flashable; if it starts with MCM or similar it's non-flashable.

If an ECU in non-flashable then all that it requires is a newer updated chipset.

What all of this comes to is this: you will need to spend about £200 - £250 to have your ECU re-mapped.

It's not possible to somehow 'get hold of' a new map for free of the 'net and download it yourself for free.

Sorry

Building on from my last question, if you send your ECU to td5alive or someone else, who fits a programmable chip, is it then flashable via OBD?
 
As in, the new nanocom can upload maps?

I guess, what I'm trying to drill down into is this: Does the ECU have the software capability to update itself, just that the chip is read only?

If so, simply replacing the chip with a similarly programmed one but which is writeable would be enough :)

If a flashable chipset is fitted, it's just like any other flashable device in that it is read & writeable.

The issue however I reckon is not the ability of the chip as that is easy to change, it's more a matter of the software to do the change and also the new maps themselves.

For example the chipset on my Triumph motorbike is flashable, so with a free to use program called Tune ECU I can load, re-load and modify the maps. However to get a new map that suited my current configuration of inlet; exhaust and sensor mods - I had to buy a new map. I then downloaded this into the bike's ecu using Tune ECU.

Yeah, but surely the actual flashing interface of the chip isn't exposed itself over OBD.

The ECU must read the command, the data, then write it into the chip. Does the nonflashable ECU have that routine?

Hi David, you are now getting into a level of detail beyond me. All I can tell you is what I've done and how I did it.


Cheers

I'm being a bit nosy, see, wondering if there's a small business opportunity in turning non-flashable ones into flashable ones that people can buy maps for ;-)

Aye, If i want to persue mapping myself (free maps are available on the net for programmable ecu's) a new programmable nnn ecu would be needed but its an outlay i cannot afford atm :( thanks for your input.
Saw one on fleabay yesterday £49.99 then realised it was for the petrol engine :(

Well David, obviously only you can decide is there is a commercial opportunity or not, what I would say is that all the post build date mid 2001 TD5's are flashable and all the non-flashable ones will have been converted as part of the re-mapping process by the likes of Dynachip, Alive Tuning etc.

I am VERY interested to know more about this please.
