is it this anyone know?

IAW48-P8 / 6160018103 that is the original Ford part number.

there are many more so called P8's than were fitted to escos. they have been used on lots of different italian made vehicles

cheers nick that explains it to a t

cheers thomas

Can you please enchance your answer ? Does it matter which ECU I'll use ?

Yes it does. Lancia run the p8 in the integrale and many other lancia/fiat/ferrari just to name a few

Try RPlabs google them.
Also www.bigturbo.co.uk

I'm sorry. I was not precise in my question. I have seen these pages (in fact I have spend most of present day on digging information about IAW ECUs)


I have IAW 04U ECU (Lancia Dedra 1.8 8V), and it internally looks similar to Cosworth's L8 ECU - but there is missing one of BDX53M Transistor (there is 5 of them - instead of 6 in L8 - there is missing far most from wiring socket) but it still have place where it can be mounted.


I hope and wonder - is it possible to complete missing parts (it seems like there is missing transistor, some drivers, few capacitors and resistors) and gain fully functioning L8 ECU (after reprogramming)


Recently I have bought IAW 471 (Lancia Dedra 2.0 8V Turbo), but I haven't got it in my hands yet, so no idea if it have any missing parts (in compare to L8).


So my full question should be: Which ECU from Lancia family I should looking for ? It seems that ECUs from Turbo version would be good candidates but there is many options.


Also - I digged that newer ECUs base on P8 platform - but still no idea if there is any missing parts inside and it will by possible to gain fully functioning P8 ECU for Cosworth.


Question on side: Is there any place in the internet where I can obtain BIN files for Cosworth ECUs ?

Loomer

I think injector drivers differ too, as some of the lancias ran high imp injectors

toyman

OK. This is very interesting information. Do you have information which drivers are used (part no.) in L8/P8 ECUs - so I can verify in my 04U and later in 471 ECUs ?


Even then - I can use injectors from Lancia.

grcossie

Easier to by an L8 or p8 Cosworth ecu, but it`s interesting to see if it works with thoose you got

grcossie

Send a mail to Rp-lab, they will now what will work

toyman

I didn't mention that any Cosworth ECU in Poland is very very rare item (I found only one for sale) and very very expensive. Buying it in UK even with present exchange is even more expensive (when you include shipping costs).


Lancia ECUs are far more affordable.


It's game worth the candle.

I fitted an entire Weber/iaw L8 with Pectel 8 injector board taken off a smashed ford sierra cos. onto my Vw turbo 16v engine years ago, ran ok but needed remapping, obviously..
I also had an L8 off a Lancia delta int.1, the version with 2 map sensors fitted, again run fine even with a stock eeprom. I modified the original loom off the Lancia to fit my Vw corrado engine, very difficult to find now these looms, no problem though, just get the loom off an old 8v hf turbo and add a single yellow wire to feed the 3 bar map sensor and your done..
I was fine even using an old L8 ecu off a 1.6 hf turbo on my old golf 2 16v turbo, was quite nippy, again, just using the Lancia factory spec.turbo eeprom so you'll be fine with the dedra's ecu, as long as it came off the 2.0 8v turbo version, the normally asp. version will run fine but as soon as the engine hits boost it'll cut out..as there's no files for postive boost. The Fiat coupč 16v turbo 4 hole injectors are very good, made by Weber, around 385cc. I used them in both cars and when running on 8 injectors, they where the first 4 to fire and the second lot were 4 Bosch orange Volvo 740 turbo injectors that cut in at 1.5Bar.

toyman

VEEDUBBED - I assuming that even on 04U with missing transistor it will be possible to reprogram/replace EPROM and run most of the Cosworth functions (I think there will be missing some not crucial function like driving amal valve which some tuners thow away)

I know one guy who successfully run Sierra on:
- IAW 049/01 WH49.07/404_4H (DELTA 1.6 8VT)
- IAW 04D WH4D.06/403_76 (DELTA 1.6 8VT)
- IAW 04E WH4E.03-085-F6 (DELTA 2.0 8VT)

But. These ECUs are currently unaviable.


I'm searching for answer - which other Lancia ECUs would be suitable and fully functional replacement for original L1-P8 ECUs.


At the end I want to replace original 27C256 EPROM with 27SF512 EEPROM and reprogram it with original Cosworth bin file - simply replacing ecu without reprogramming is not an option in my case.

VEEDUBBED - Can you tell me which part number have you used in your projects ?

Jan300

Some lancia turbo use also two mapsensor so you must know exatly what to do to make it working.

toyman

Can you say which use two map sensors ?


Is it possible to connect two MAP sensors into IAW ECU ? I think there is no way to connect anywhere another/second MAP sensor - almost all pins are utilized.


Some of the 2.0 Turbo runs on Bosch systems. Maby you talking about such configurations ?


Can you put some more about models, year of production, any further information about this ?

Jan300

Look at engine wiring diagram and ecu pin out for the ecu and you will see.Lancia diagram.I think its up to evo 1 cars.Last Lancia evo cars running P8 ecu and as I know one mapsensor.

VEEDUBBED

I reckon Your gonna have more trouble trying to find a good 3 Bar Marelli map Sensor than any ecu, they cost nearly as much too..
The only car that ever ran 2 map sensors (That i'm aware of) was the '89-'91 non cat evo deltas.
All you need to do to make both map sensors work, apart from the obvious ecu, chip a map sensors, is a Yellow wire added onto the look off a not so easy to find delta turbo.
I'll pull out My delta manual later and show you what pin numbers are used.
Do you need the number of the actual ecu or eeprom inside?
Why not just buy My Pectel super 8 injetion set up and run that?..

toyman

MAP is not problem in my case. I've got all engine sensors and all other stuff like injectors, ignition distributor, etc. in fact I've got 2 and 3 bar MAP sensor.


Unexpectedly today i received IAW 741.08 ECU. Internally it looks exactly like Cosworths L8 (IAW 48.08) on bigturbo site. Including daughter board.

midnight_man

I am dealing with same problem..I have here about 20 pcs of IAW ecus...trying to make L8 or P8 ...

but its not so simple...P8 ECUS from fiat/alfa/lancia..loooks same..but most important are peak/hold injector modules...only cosworth P8 have them! no one other IAW P8 has these modules ...so only 1 way is make them.
