Will a HDI 136 ECU work in a HDI 110? - Update - 'No'

[Steve406HDi]

Hi all,

I've finally got round to swapping my ECU/BSI/Transponder & Chip to cure my engine immobiliser non-start problems (thought it was fixed - turned out it wasn't).

I fitted a ECU/BSI/Transponder that I was incorrectly informed was out a HDI 110, and after a HPi it turns out it was a 406 HDi 136 2.2 registered 22/08/11 4-door 5-speed.

My car is a 406 HDi 110 X-plate 2000 registered part-multiplexed D9 saloon.

The engine now starts and runs everytime, but there is no rev-counter working, no temperature gauge and no boost! (although the engine runs very well with this very minor exception lol!). The engine did run well the one time I managed to drive it during the persistant immobiliser problems prior to changing the ECU, so I'm pretty certain there is nothing mechanically wrong with it.

I'm hoping I can just upload a 110 map to the new ECU and everything will be back to normal.

So, will this work? The Bosch ECU EDC15C is the same, although I don't know at the moment if the part numbers are the same - I would guess not.

Does anyone have a HDI 110 map, standard or modified, I can try? PM for email address if anyone is willing to send one over to chance. I appreciate I might end up bricking the ECU, but I've got nothing to lose as the great car park in the sky will be the 406's new home if I can't fix it. I've ordered a KWP2000 in anticipation.

Thanks all for your help
Steve

I suspect you're going to struggle with this one, the 2.2 has several more actuators for swirl flaps, throttle bodies and vgt turbo etc. It's true they ae both EDC15C2 ecu's, but I think there may be more differences in firmware beyond the more easily changed map. Still, no harm in trying.....

If it's any help, when I tried a semi-mux 2.2 map in my fully mux car, the rev counter didn't work either.

If you PM me an address, I'll e-mail you a couple of example semi-mux 110 files to try. You might get lucky, but my limited experience of 110's suggests there are many incompatible map variants, (not just the semi/fully mux flavours you get with 2.2's).

I note you're not that far away - I could probably sort the stereo with PP2000 for you.

Thank Doggy,

I've PM'd my email. Thanks also for the offer of PP2000, I may take you up on it. I'm going to see if I can sort this ECU first though. You may be able to give me a clue as to whether my keys could be reprogrammed to the new ECU to get remote central locking back again in due course. Central locking working fine on the key.

[Doggy]

Yes the keys can be reprogrammed. If you're lucky, just pressing the button while they're in the ignition will do it. If not you need the 4-digit pin code you should have got with the car to enable key configuration in PP2000.

Key won't resync, tried that already using sync methods from here and Autodata. Autodata advises programming is done 'via diagnostic equipment' but not sure if an already-coded key can be recoded - Renault's certainly can't. Plus although I have this car's keycard, I'd need the code from the car the new ECU came out of won't I? I now have the VIN number so I think it's about £6 from Peugeot Codes, but all in good time. ECU first

The keys can be reprogrammed.

If you have the VIN, sign up to www.digital-kaos.co.uk & look for a post entitled Peugeot VIN to PIN, (or something like that), post the VIN, you'll get the PIN foc within 24 hours.

I will take a guess that if you get a HDI110 map on there all would be well.
Might be a good time to get the car remapped?

Hi

I think if you can get a 'right' 110BHP map you'll be laughing. I know for a fact the VNT turbo control can be turned on and off in the map, so don't worry about that. Post back with how you get on! (might be useful to know for people with 2.2s who might need to use a 2.0 ECU in the future)

nice one! thats actually helped me out a load too as my car never came with a pin!

[Steve406HDi]

Hi all,

Just to update you guys who have helped/are helping me out:

Doggy has sent me a couple of map files to try, one standard, one not. My KWP2000 has been posted so should be with me tomorrow with any luck.

Posted on the digital-kaos forum to get my PIN for the new ECU.

If anybody else has alternative map files, please PM me as I'm happy to try other alternatives as well, try and get some data together as to what can be done/can't be done.

FYI, my old ECU (HDi 110) is hardware version 248, whereas my new HDI 136 ECU is 370.

Thanks all,
Steve

Thanks for the heads up for this - it took them 7 minutes!

Update:

KWP2000+ arrived. Installed on XP laptop yesterday. Plugged into OBD2 port today.

I can get as far as reading the hardward and software versions, but the moment I go to read the ECU file, I get an 'internal hardware error'. I'm assuming this relates to the KWP2000+ box itself rather than the ECU (or laptop for that matter). I installed the COMPORT before loading the software.

Any ideas/help would be much appreciate. Have I got a faulty KWP2000?

Thanks guys

Steve

Never tried a KWP, (I've got a Galletto). Try connecting it to another car, (if it's like the Galletto, it should connect to just about anything).

[rlees85]

You will have an option of 'fast' and 'slow'.

Fast is the default option, make sure you use slow!

Let me know how you get on

Update -

KWP2000 would not work with my 2.2 HDi ECU, it would read the versions but not the map or reprogramme the map. I bought a (cheaper) Galletto 1260 and hey presto, no problems, and it also worked on my Vista laptop instead of having to borrow an XP laptop. It read the hardware and software versions no problem, it read the current map (and saved it to my laptop) and would update the alternative maps to the ECU.

The good news is the temperature gauge worked. The bad news is the car wouldn't start. It turned over and tried to fire a few times but just wouldn't catch. I tried both the standard map and modified map, both with the same sypmtoms. I put the 2.2 map back on and it started first time (though with the same problems I was having before).

So simple answer - No, it won't work on a 2.0 HDi 110. Still, there's a bit of research that someone else doesn't have to do now.

I've taken the 2.2 HDi ECU/BSI/Transponder ring back out of the Pug and sent it back to the supplier, and now await the correct 2.0 HDi set. Once it turns up, fingers crossed, it'll be up and running (and possibly modified) in no time at all.
