1.2 16v 18FD ECU remap for 1.4 engine

[Geborga]

I have a Mk1 Punto Sporting. So the standard engine is the 176B9000, 1.2 16V 86bhp. Together with the Marelli IAW 18FD.5Z ECU.
I installed a 1.4 16V engine, with the Punto's intake and exhaust manifold, cable throttle, injectors, etc.
There are a couple of threads on builds like this in Centos.
Problem is, it has flat spots, so I need an ECU remap.
Is there anybody who either sells modified chips, or have an existing XDF file for it?
Current setup is:
192B2000 engine (1.4 16v, Bravo MK2 2008)
176B9000 intake manifold, 200cc injectors, exhaust manifold, accesories (Punto Sporting 1.2 16V 1997)
182B6000 throttle body (Brava 1.6 16V, 46mm, I had this on the 1.2, worked flawlessly)
Plans in the future:
Install the 176B9000 cams, and a different, tubular exhaust manifold.

Hey there. I have exactly the same problem..
Did you find any answers..? I'm told the ECU has to be physically modified first, so that the remapper can connect and change code.
Cheers, thomas.

Hi!
I didn't solve my problem. But I decided to go for an ECUMaster DET3+ piggyback for the 18FD, put in a TJet engine+C510 gearbox+Punto GT driveshafts, knuckles, adapt the cable throttle body onto the engine, and I'll have much more power. (I don't have the funds for a proper standalone, but it would be soo much better)
Some 18FD's will have socketed EEPROMs, some have soldered. The only way to make sure, is to open it.
There is somebody, who makes chips for them, but he's very pricey (450eur+). He has a company, Reprog Italia, and he's called Dario Lorenzoni.
Also there is somebody, who has done this 1.4 N/A conversion, with the 18F(P75 ECU)+DET3 piggyback. Here it is: https://www.fiatforum.com/threads/fiat-punto-sporting-100.477263/

Brilliant. Thanks for the info. I'm liking the sound of the DET3+ piggyback - went down that wormhole for a couple of days..

Seicento - Monster Cento/ECU Master Thread

Honeymonster submitted a new vehicle: Monster Cento/ECU Master Thread Well starting this is well overdue although technically it's still just a car and a big pile of bits at the moment. It will come together quickly though as I have access to a commercial garage in the evenings and on weekends...
