Good evening all, I'm on looking for a bit of help or advice :) I won a remapped TD5 ecu on ebay and cannot get the defender to rev on it at all. I swapped injector codes and reprogrammed the immob ecu and it wil start and idle fine but once you rev it the engine cuts out:confused:
Any ideas?
Thanks in adance
John
 
Check the throttle pedal setting. This happened to mine when I accidentally changed it from a two wire to a three wire setting whilst recoding my injectors. I **** several bricks until I realised what I'd done.

Does your engine management light come on and stay on before you start the engine and while it is running?
What did you use to program the injectors? Was it a Nanocom per chance? The original Nanocoms default to to a three wire throttle setting and you need to manually change it back to the two wire setting every time it writes to the ECU. Or at least the one I used did.
 
Thanks for the prompt replies lads, The defender is 2003 and I'm unsure of the year of the ecu I bought.
I did use a nanocom to swap the codes, how do I change the throttle setting?
Once again Thanks
Cheers
John
 
I borrowed Ratty's Nanocom to code my injectors when I fitted my new engine.
You need to page through the Nanocom options until you find the throttle setting option. From memory it was about two or three options from the injector codes but I dont recall if it was before or after them. There are only two settings so its not hard to sort out. I used the Nanocom in "stand alone" mode which makes things a bit more complicated as my laptop played silly buggers when it was connected.
 
Thanks, Just tried this a few times but it's still cutting out when you floor the throttle, even when it's changed to 2 way setting?
cheers

When It cuts out it wont restart or a few mins with new ECU but will restart instantly with it's own ECU reconnected?

The TD5 ecu contain the following faults:

FAULT 01-05 Turbocharger wastegate short circuit (INTERMIT.)
FAULT 02-08 ambiant pressure circuit (CURRENT)
FAULT 04-01 Inlet air temperature circuit (INTERMIT.)
FAULT 04-03 coolant temperature circuit (INTERMIT.)
FAULT 10-01 air conditioning fan drive open load (CURRENT)
FAULT 10-03 tachometer open load (CURRENT)
FAULT 10-04 gearbox/abs drive open load (CURRENT)
FAULT 10-05 air conditioning clutch open load (CURRENT)
FAULT 14-01 air conditioning fan drive open load (INTERMIT.)
FAULT 14-03 tachometer open load (INTERMIT.)
FAULT 14-04 gearbox/abs drive open load (INTERMIT.)
FAULT 14-05 air conditioning clutch open load (INTERMIT.)
FAULT 28-07 topside switch failed pre injection (CURRENT)
FAULT 30-07 topside switch failed pre injection (INTERMIT.)
FAULT 31-01 injector 1 open circuit (CURRENT)
FAULT 31-02 injector 2 open circuit (CURRENT)
FAULT 31-04 injector 4 open circuit (CURRENT)
FAULT 31-05 injector 5 open circuit (CURRENT)

Ecu No is NNN500020

Thanks
John
 
I would say its those topside switch faults which could be causing you some problems, they will also cause all those injector faults to.

The topside switch fault refers to 2 capacitors inside the ecu, these are used to generate the large voltages needed in order to fire the injector solenoids, ecu is basically dead, hence why it restarts instantly on your original one !

Oh No So it's Donald Ducked altogether? or can I rectify it?
Thanks

I have never found anyone who can repair/ is willing to repair them but i don't see why they can't be repaired, maybe it is not cost effective ?

Saying that when we supply new ones they want the old unit back for exchange so they must be repairing them or reusing something from them !
 
Thanks very much for your help:)- Feck it anyway, looks like I was rode wih the ECU, Shows the danger of buying secondhand off EBay:doh:
The Price of the ECU along with Buying A nanocom would have paid for a remap of my own ECU:eek:
Thanks for l the help lads
Cheers

If you paid for it with PayPal go to them and get your money back. Just tell them goods not fit for purpose, describe the problem and they will take the money back from the seller under their buyer protection scheme. Happened to me once and PayPal were great. The onus was then on the seller to argue the toss which he never did (an admission of guilt in my book). The only thing I never got back was the postage.

Also report the eBay seller so that nobody else falls foul of them. How to do it is clearly shown on eBay. Dont roll over with out a fight.

Thanks for this Info but I have it a few months s I'd to get a Nanocom to program it and a few other things so I'd say I've bugger all of a case but I'll give it a try:)

Allcar electronics in Alfreton,Derbyshire have successfully repaired a couple of ECU's for me,(Suzuki Jeep and Pajero V6) but they were both old and presumably fairly simple.I have yet to find anyone who can properly test later Bosch units,one unit was sent to two places who said it was OK,(One later admitted they could only test various functions - not ALL of it.) but a new ECU eventually got fitted,programmed and it fired right up.
The last two TD5 engine ECU's I have fitted came from my local main dealer and were outright - no exchange.
 
Erm is it just me being thick as a brick orrrrrrrrrrrr:

I believe I read somewhere on the forum that your Nanocom can read and save a copy of your existing map from your ECM and store it on your computator thingie.

Ermmmmm get the idea?

Read the healthy ECM's map - save it to computer.
Read the duff ECM's map - save it to computer.
either test the duff ECM by writing your good map to it and see if it still has problems OOOORRRRRRRRR
Write the re-mapped data to your existing ECM and see if that works out. If it doesn't then write back the original mapping to your own ECM and your back where you started - or you have a good ECM with good re-mapping and a faulty one to claim your money back on.............. If you were devious that is Hee Hee.

I don't have a Nanocom and know nothing about them (I have a Hawkeye), but I do know there are peeps on here who do have them and know how they work!

Ron.

However - I would have to say, that this suggestion is only for educational/thought provoking purposes and if you do try it then you do so entirely at your own risk !!!

Although some of the early ECUs were not rewritable.

I just sent you an email Shifty, looks like I am going to have to replace my ECU. The dying trick is back and I have the dreaded Top Switch errors showing up.

Erm, what's this all about?

What's your opinion on this?

AAAAAAAAAAAArrrrrrrrrrrrrrrrrrrrrrrggggggggggggggggghhhhhhhhhhhhhhhhhh.

According to that webpage I just linked to, my ECU should be an MSB000080
and the number on mine is: MSB101171

What the hell is that?

R.
 
Thanks for all your help lads, The map swap didn't work but my 110 has developed more torque and power and goes like stink for some reason;);)
I'm off out for a blast up the Motorway, Delighted.:D
Cheers
