Changing ecu

Hi just finished fitting second hand engine, engine came with ecu that has had a 5 alive chip fitted, so would like to try it. Engine runs with old ecu with no problems, started first time, just a fuel leak because I had forgot gasket as I was being extra care-full with the o ring so fitted gasket and all okay, I have a nanocom but can not find out what or how or where I need to change to get it to work. I think I need to relearn the security code but how? I am sh## with computers so any help would be great

You say you have a Nanocom. It all depends on where you got it and therefore what vehicle type it's set up for.
If you purchased it from Nanocom, BlackBox Solutions then you would have been given a password by BBS to gain access to the "Restricted area" of the website where you would be able to obtain the various unlock keys for your vehicle.
If you purchased it as a second user and it has possibly been set up for a different vehicle type, then you should try to get the BBS password from the seller. If you are unable to obtain that information from the seller, then it might mean having to send the unit back to BlackBox for them to do a full reset of the device and give you the new set of information.
If the device is for a D2 and has been unlocked correctly then you can obtain all the user's manuals for the Nanocom from the BlackBox Solutions website.
The Nanocom doesn't have an internal battery, so it won't work until it's either plugged into the diagnostics socket on your Disco or plugged into the USB socket on your PC in the case of unlocking or updating the software.

Td5 Engine - UTILITY - Learn security code, also in the old ECU you have to save the injector codes of the "new" engine as to be 100% well

Plug your nanocom into the car & get it powered. Choose TD5, then security relearn. The option of "other" may come after TD5, but either way you get there, you need to acrtivate the security relearn. Turn ignition off for 15 secs, then you should be able to fire up. If the engine TD5 ecu come with the engine then it should be a straight swap over.
I swap TD5 ecu's all day long. easily 10 x a day, possible 20. I've never had to worry about injector codes or such. I just use the security relearn,.

It means you do an incomplete job for your customers cos without the codes the engine will not run 100% well, especially not at high revs

What are you talking about?

I've never had that problem in 15 years & never ever received a complaint or negative feedback mentioning injector codes ever. & trust me, I do a damned lot more than what you do. But then I notice you use hawkeye as a diagnostic system. The nanocom is better. Get up to approx £80 to £100k in diagnostics, for the bench & vehicle, & then come & have a discussion with me.
As for " Doing a bad job for my customers" you haven't a clue who our customers are, but thanks for the giggle on this fine Sunday morning.

Sorry to annoy you Sunday morning but first of all you started this with that statement that you dont care about injector codes, also if you watch better you'll see that i have 3 kind of testers nanocom included + a proffesional oscilloscope + a smart multivehicle tester too which covers the whole range of LR's with good programming capability(i've set RRS height with it for friends FOC as i'm doing all that by passion and love for Land Rovers) also i've made various tests on Td5 ECUs, .... i've seen enough ''specialists" who dont care about the customers much just doing perfunctory jobs without even studying deeply before just ''fix it fast and get the money" ... if the customers didnt complain IMO they dont even know how that Td5s would work with coded injectors cos they are pleased it's running after they ended up at your service with a non or bad running one.... i can come to discussion with anyone on a open forum though also i've spent the last 10 years since i bought my D2 studying hard about it with enthusiasm and the fact that you insist about the futility of injector codes on a Td5 is only in your disadvantage , read at least the last paragraph of this document http://dieselclass.com/Fuels Files/Delphi E3 Diesel Electronic Unit Injector 9-10.pdf , and maybe you'll take a short look into the Td5s workshop manual too in behalf of your future customers or at least dont discourage owners with theyr own tool to do a perfect job and code the injectors too

aamof your superficiality is shown by this statement too

cos as i said in the post before your's it's in UTILITY not "Security" and it's Learn not "Relearn"

You've lost the Thread.
He's replacing his engine, The engine he purchased came with the ECU. He can use that ECU with no specialist programming as the injectors are already programmed. Therefor, would you agree that I'm correct in my beliefs that he doens't have to program the injectors. You only program injectors if you've replaced any of them, or you're fitting a replacement ECU.

Would you also agree, with your experiance & knowledge, that TESTING or REPAIRING a TD5 ECU that will be fitted back to the same vehicle, also doesn't need injector coding?
Secondly, you keep refering that we are operating without a duty of care towards are customers. I haven't a clue as to why you'd want to even mention this. Maybe you've had something happen to you that you're festering on?

I understand you may be under a little pressure, or even stressed, but re read the thread. I can see someone replying to a question with a instructions that are irrelevent to the original problem. He doesn't need to program injectors on an ECU that was previously running the corresponding engine.

Now, I have nothing to prove, I will discuss anything in the forum, But I believe these forums are to help people, & I spend a lot of my time on forums or on the phone advising owners, independent garages & quite a few main dealers, all free of charge. I'll help anyone with no nonsense advice & will directly instruct them if needed. The knowledge I've gained over the past decades I share. I don't complicate matters to make me look special. I don't tell people that we use bespoke diagnostics to make us look any more important, nor do we mention our scanners or scopes or any other equipement like all our hand made bench test looms. As I said, these forums are to help people.

Now getting to the point. The original post asked the said question. Can he use the ECU that came with the matching engine. He also explained he wasn't to hot on the nanocom. My reply was a straight forward responce. Yes he can use that ECU & all he has to do is to activate the TD5 security relearn. There's no need to complicate the matter by mentioning having to program the injectors. This will give the poor chap anxiety to the point he will be worried about using his Nanocom.

I'm affraid i didnt lost the thread at all but maybe you did, my first reply to the OP was perfectly on the subject to help the man and telling exactly what to do with nanocom to set the ECU which came with the engine(and presumably has the codes saved) which is not fitted now (as that was his question) and advising him to code the injectors in the OLD ECU which is now with the replacement engine as to have a good spare:

after this reply of mine you came with that ''relearn" thing and stated that no need to code injectors as you swap 10-20 a day just making them learn the security code without worrying about injector codes so you was trying to help the OP by missleading him(for the future) nd others who are reading this that the injector codes are irrelevant and IMO that's WRONG ... as about helping people i'm quite relaxed that i've helped enough when i could in this forum and in others without being recommended by a main dealer(which from my own experience with main dealers i would not need at all cos the last one i spoke with thought that the Td5 is a BMW engine) and i dont think that i want to look special when i spend hours digging in diagrams just to help members here or elswhere with electrical problems

the gist of our discussion still remains the same: Do you still insist that no need to code injectors when you swap an ECU just make it learn the security code and not "worry about injector codes or such"(your exact words)?

Hi thanks Rick and all for your help got the new ecu to work, I do not understand why but I made a note of injectors and when I first put the ecu in all the injector codes where correct but after it went through the security relearn the codes have changed, I need to look at old engine to see if they are the codes for that engine I can change them no problem but did not think I would need too. Had problem with fault on system saying open circuit on injector 4 I think engine might be running on just 4 injectors, Check cables and found a pin broken where wiring harness connects to cables inside rocker cover it is the connection on the car not the engine so will have to some how use the connector that came with engine, (had just been cut off) I think I will solder the wires then cover with heat shrink unless some one has a better idea, may-be after I can look for a second hand harness for this or may-be some one knows where to get a new one at a good price, thanks again

Was there oil in the loom of the new engine? (in the connector that is mounted on the head to bring the connections outside of the head). If so, don't mess about, get a new injector loom and keep cleaning the oil out of the red ECU connector, this can also be the cause for funny injector codes (although, doesn't appear to be in this scenario).

Do you mean the pin that's on the connector attached to the injector loom, or the connector that connects to the injector loom?

hi sorry to say it is a pin on the wiring harness and not on the injector loom I already fitted a new injector loom when I fitted the engine the connector must have broken when I took it off there was some oil in it and I cleaned it but think the broken pin is the problem

Yeah, does sound like it. I think you can get the pins, even the female ones.

Perfect. Patience is under estimated but vital in fixing these things. You can have all the tools & diagnostics in the world but without patience you just go around in circles.
I know what the nanocom is capable of, & although I use the same software just in a different package, has it got the option of ECU check? This option checks the ecu & links are all correct? This option is very helpful in deciding whether it's a wiring issue or a fault with one of the modules itself.

Hi changed plug and now all injectors work and no fault codes, got to drive it and runs well with no sign of leaks, have a problem with turbo when it is working hard but think the turbo is set up for the 5 alive ECU and I think I am a bit missing, on utube when the 5 alive ECU is fitted a small box is added to the plug of the ECU this I think this is to allow the turbo to have a higher pressure? and I do not have this box, so think the turbo needs adjusting back down or I need to find one of these boxes
