Trip Computer Guide (HDI)

[Niall]

406 forum. The same ecu and engine was used in the 406 with the d8 trip computer

[DeeTurbo]

Haha, that's the same place I was going to look.

Would you be able to double check it in autodata easily?

[Niall]

yeah will do tomorrow when im on my other computer.

[MiiTCH]

If its 100% certain on the right pin for my ECU I could pop over to Dunstable if I get hold of the little trip computer

[Eeyore]

Just picked up two trip computers for £5 from my local scrappers. Hopefully they are the right ones! Ill post some pics shortly.

[MiiTCH]

What car were they from?

[londondan86]

I picked up a D9 one from a 2001 406 hdi estate at my local scrappy. What extra work will be required to fit or am I better off just going back and looking for D8 one instead?

Cheers

[HDIkyle]

The problem with the scangauge is when you take your foot off the throttle or sat in traffic the MPG shows as 9999 which then sends your AVG MPG up I had mine at over 100mpg sat in town which is pointless and useless....

[Eeyore]

What car were they from?

Early 406s. Had the P1 front end so hopefully they are the D8 ones! Doubt they will be the D9!

[MiiTCH]

Ill have to take a trip down to A5 Salvage and see what they've got

At the moment no one has retro fitted a D9 unit yet, Niall is working on it though.

Did you manage to get one?

[Leemus]

might have to do this on the estate im only in luton so will pop over and give you some beer tokens for doing it

[DeeTurbo]

Yeah, no worries just let me know when you want it doing.

[Niall]

Dee just a quick question. How did you fit the TC in the dash. Its a very tight fit! lol

[DeeTurbo]

Yeah it is a bit. I took the connector off the board and soldered wires from the connector block to the board and also there is a black plastic lug behind the clock that a broke off.

Have you connected the low fuel wire, I haven't and it seems my estimated fuel in tank isn't working right at the moment.

[Niall]

No I haven't yet. Also need to do 1368 but I've been having trouble opening up the ecu plug (it's different from the hdi ones)

Hi guys,

And congratulation for this tutorial. I'm a French owner of a 5dr Peugeot 306 HDi and I found this topic searching randomly pictures with google images.

I registered because I would like to help you as much as I can because I'm also a member of a French 306 fan forum : 306inside.com and we have been debated (and done work) about trip computer from different peugeot cars for 2 years now.

Yes, it's pin 63 for ECU Bosch EDC15C2 but with one plug (K-line) ONLY ! I don't think it's available for the latest ECU provided with the 306 (2001 last models) with has 3 plugs (Can). I need to find the topic on the forum, but i gill post tomorrow the correspondance for other petrol ECU...

We started with the trip computer of the oldest Peugeot 605 because the form factor of this one is exactly the same as our clock/temp of our 306. But unfortunately this TC requires a specific fuel gauge and numeric instrument panel which is very difficult to clone in our cars. Moreover the capacity of the fuel tank of the 605 is different.

So we looked at the TC of D8 406 (many thanks to 406oc yes wich gave us a lot of useful information !)

But i don't understand why you are talking about BSI (as our 306s are not multiplexed) and retrofitting a D9 trip computer (which in fact just a Multi Function Display working with the BSI and the multiplexed architecture of the d9 later 406s, 307s etc...) ? Did you manage to "multiplex" the 306 ?

---

Sorry for my language, I do my best to avoid mistakes, but... I'm French ^^

[DeeTurbo]

A lot of people call it the BSI here but yes you are right that it's technically not.

That would be nice if you could inform us of the pin outs from other ECU's here.

[paulo953]

Here is what I found for the moment, I will update the list as soon as I get more info :

XU10J4RS - 2.0 16s 167cv ECU Magneti marelli IAW 1ap10/ pin N° 5
XU10J4 - 2.0 16s 135 cv ECU Bosch MP5.2/ pin N° 4
1.6 8s ECU Bosch MP5.2/ pin N° 4

---

Got from 406oc :
1.8 16v (Sagem sl96) and 1.8 8v(Magneti Marelli 1AP.20) / pin 5

[Birk]

Could you not use a trip computer from an early 307/206 that doesn't have a proper bsi unit? From a hdi that is, just mimic the wirring. I'm pretty sure the plugs are the same as 306 temp/clock aswel.

[paulo953]

As far as I remember, just upper range 206s not multiplexed like the s16 with GPS version did have an external display, but this one was used for temp/clock and gps only and didn't have any chip for trip computer.

I didn't know for early 307s.

---

Correction : it's a Multi Function Display for multiplexed version... So it was not very useful for the first 206s but became useful when bsi and com2000 went... And then there are the different type A, C, CT displays... But it's not for us ^^

[DeeTurbo]

Paulo have you fitted a TC to your car?

[cully]

Yes, it's pin 63 for ECU Bosch EDC15C2 but with one plug (K-line)




ONLY ! I don't think it's available for the latest ECU provided with the 306 (2001 last models) with has 3 plugs (Can).

are you sure pin 63 as i believe K-line is 38 ?????

also is this any help for the 3 plug???

   

[DeeTurbo]

Cully, do you have a list like that for the three plug ECU.

[cully]

no im still hunting that one down

[Pipps]

A trip computer would be epic! Good luck guys

[paulo953]

@Deeturbo : I partially did yes. I mean : I get all the stuff to do it, changed the wiper stalk and connected to the ground. Changing informations displayd by the TC works. But didn't get the time to do more so far. But few of my friends did.

@Cully : I'm sure yes. We have the same diagram and check line 63 it is written (trip computer). Pin 38 is for diagnostic plug to link the ECU to a computer. and to allow "discussion" between them.

Pin T1 is the same as pin 38, but for the last Bosch ECU models with 3 plugs. I call it "Can" because according to many technical documentation I found on the internet the ECU is named like that. And assuming that later cars like the 307, 406 d9 etc... where provided with multiplexed CAN and VAN networks and where using the same ECUs, I think that this ECU is ready for multiplexing.
But honestly, i don't know if the "language" between ECU and the computer with PPS is changing and I don't know how to check it....

Don't know whete you find your diagrams but those are very useful Gonnat download it, it can be useful.

---

@Deeturbo : I've seen the TC working but it seems we (every person who made the mod) are stuck to the same problem : for the autonomy, TC is displaying "--" sometimes and unable to change it. I think this is because we didn't allow every pin of the TC to what it is supposed to be linked.

That's why your guide is better than our, because it's the first time I see the "low fuel" pin on a diagram. Maybe it could be the solution.

Cheers, Thanks for that. Looks like I'll have to wire a TC in a different way in my girlfriends car.

I've not had chance to strip the instrument panel to connect to the low fuel bulb yet and because I've not I think my estimated fuel in tank isn't working because of this?

[paulo953]

As the 2 parts of my posts are link, I would rather say "Yes, I think it's because of this" to the 2nd question.

Sorry, I try to do my best for my expression in English, but i don't know what is gramatically incorrect or what kind of expression is not understandable in the context.

When i will do the plugs I will try to connect this "low fuel bulb". We already noticed that Peugeot 605 TC had more wires coming from the fuel tank...
