Hi, in these ecus it’s not possible to have negative advance via software.
The only way to obtain negative spark advance is to move the VRS, as done for stock 18FD vehicles (-18 degrees).
In this ecu is impossible to have negative advance too, but actually the 0 value means -18 degrees and so on.
 
I have a problem with the engine stalling.
When I am in cut off mode, throttle on idle, engine speed above 2000 (I set cut off at 1900 rpm), if I disengage the clutch, the rpm goes down and the engine stalls.

I can't find the bit that controls the resumption of injection (which is around 1400 rpm);

And I also think that I have to play on the position of the idle stepper but here too I did not understand the function of all the maps of the idle stepper.

I built my own xdf based on that of woj with identification of many additionnal maps but some are still unknown to me.
Now clear understand what is happening on Ethanol .

It is possible turn off cut off mode. Try it and check. Set some low value below idle or 0.
Let me know write there.

Please put your xdf file there.

I have the same problem as you. The only difference is that I work on a five hundred 900. I have gaps below 3000rpm.
Use map F6FF to tune your additional fuel need to turbo.

hi all! I dumped a IAW G7.11 from a Fiat Uno Start 994 i.e, tried to reverse engineering but without success.

Can someone understand, more or less, if there are maps similar to those of other IAWs? It appears totally different from 16F and 4F despite being from the same family.

My project is to use it on a Turbo engine (Lancia Y10 Turbo, electronic injection, distributorless ignition), so i need to work on fueling and ignition advance.

Thanks!!!

Having said all this, for those who got excited already, I need to destroy your day a bit. It took me close to 2 years of some of my spare time to analyse and experiment with the ECU to fully dissect the 8F/18F program. This is also the reason why I am not that eager to share too much of this, so that eBay will instantly become full of modified programs. But, for the brave ones that want to try things out I attached some images to this post, compliments of the Polish Centomania forum :worship:.
Hey Woj,
i will respect that. But can you public Spark Map from IAW 18FD 16V ECU? Than i can savely tune my engine with Speeduino.
Thanks!

Has anyone that is actively studying these ECU's figured out which part of the maps relate to the purge valve and how to delete/disable them to reduce the amount of autocorrect variables?

It was suggested before to raise the activation temperature to a very high value so that its map basically never gets applied.

But can the whole call be deleted so that the ECU thinks it was never fitted?
 
Hi. This has been an extremely interesting read. I have been comparing several maps between cinq and seicento.
I have been using the XDF provided by woj. My question is why does the original ECU dump provided by woj read just fine using tuner RT. If I try read my own dump from a seicento it does not display the correct values in tuner RT. Am I missing something very obvious? 🙁 I have tried several dumps from IAW ECUs.

it's normal; there are sometimes shifts in the maps depending on the ECU;

for example on cinquecento sporting, the fuel correction map located at address F175 will be located on a seicento sporting abarth at address F1B4; it will be located at F173 on another version.
