I've replaced original engine of my 2007 120 bhp 1.6 with the 2002 150 bhp 2.0 and ECU but got some issues I can't resolve.
Actually the main PIA is that I can't reset the instrument panel which beeps and flashes with all warnings! I tried the proxy alignment procedure via multiscan but it just hangs up halfway!
Another question is about board computer. Is it really necessary to replace it too? Or the old one will do?
Thanks for any help!

Did you replace the ECM?
As for the instrument panel, 1.6 has a lower redline (~6.5k instead of 7k). It used to be on GTVs that you could swap the clusters between different engines with almost no issues - the worst thing that could happen being your revs not reading correctly, namely when swapping V6 and TS clusters on PH1. With later cars however, I'm not sure if you can get away having a cluster meant for another engine.

If you mean ECU - Engine Control Unit which is mount on the engine block, sure I replaced it. Rev line is not big deal, I bother only for warning lights and beeps! It's usually cured by proxy alignment procedure but not this time!
Do you think I should replace the original instrument panel of 1.6 with the one from 2.0?
How about board computer? will the old one from 1.6 do?

Yes, ECM/ECU.

Look up the previous threads, it would seem that body computer / BCM need to be from 2.0TS too

147 1.6 to 2.0 conversion

Hi all, so basically i bought a 2003 147 1.6 a few months ago, its a GTA replica and looks the part but sadly doesn't really have any poke to go with it :rolleyes: So ive been looking on ebay and found i can pick up a 2.0L engine for around £300 with decent millage. Now i am confident with the...

Yep if you change the engine ecu you need the matching immobiliser system (body computer in a 147) and keys from the same car.

That brings the set of problems that the BCM must be compatible with everything else in the car. In many ways, it may it easier to have the original 1.6 module remapped to run the 2.0. Depending of the pin data and internals, it may or not be possible to run the variable inlet manifold on the car.

Even virginising the 2.0 module may still leave you with a compatibility issue. You either need specialist advice or start closely analysing wiring diagrams for the different variants to take this information to someone who is really good at remapping who also has specific knowledge of electronic systems.

I have looked though that thread before but couldn't get the answer to my question regarding flashing warnings on the instrument panel.

I have absolutely no issues with compatibility, wiring, VM, keys, whatever. System scan shows only usual problem with ABS you can't cure without ABS module from 2.0 but what I need is to finish proxy alignment to get rid of flashing warnings but the procedure stops halfway!

So I guess the solution can be either to use another tool, not fiat multiscan or replace the instrument panel with the one from 2.0

My question was about flashing instrument panel, no issues with immobiliser so far.

 

[sprint_veloce]

Cool, so the car starts and drives? Wasn't clear from your post. So exactly what warning lights and messages are you getting?

Yes, the car starts, drives and shows no errors when scanned with FiatECUscan. But dashboard flashes with all warning signs possible: engine, abs, asr, etc.
I guess the instrument panel needs proxy alignment and I starts OK but stops halfway. The question actually is if there is another way to do this procedure, maybe with another tool?

 

[Fruity]

Yes. The engine will have starting authorisation but the engine module may cause compatibility errors. I'd see if that is the case and possibly try the 1.6 engine module to see if that sorts it.

Of course the old ECU from 1.6 sorts out this problem but the engine works in abnormal mode because it's 2.0!

 

[Fruity]

OK. That suggests a compatibility error. I know others have had success but I think the specific version may be a factor. Have you scanned the car for fault codes?

Was the 2.0TS engine and ECU from a 147 or a 156 ?

FiatECUscan shows only usual after swap ABS error you can't cure without ABS module from 2.0
No engine or other errors.

Is the dash flashing because of a CAN issue with the apparently incompatible ABS module?

I've replaced the engine of my Alfa 147 2007 120 bhp 1.6 with the one from Alfa 147 2002 150 bhp 2.0. Of course every engine got it's original ECU.

Of course ABS warning remains even after proxy alignment just because ABS modules in 1.6 and 2.0 are different, but all other warning like check engine or brake pads wear should clear off! Just because there are no such errors while CAN scan!
