Technical DIY ECU for Panda Turbo
I don't have the dump from the 1.4
ECU memory dump from the 1.2 is attached for you to have a play with
But as you can see unless you have purchased the correct software it's useless
Trying to turn a 1,4 into 1.4 tjet is not the way to go in my opinion, but it your car you can do what you want
The tjet is a completely different engine
different head design
Camshaft housing
Camshafts
Forge crankshaft
Different counterweights
Larger flywheel bolt
Pistons
Extra cooling in the crank case
And so on
Without lower the compression the amount of boost before the engine disintegrates is very limited
There's much more information in the punto sections, but don't believe the quoted bhp unless it's been on a calibrated dyno
It's more cost effective to get meaningful power increase to swap the engine for say a bravo 1.4 t-jet

what CPU is it for and what address does the dump start from?
No
There is a copy on mhh auto but you will need to register to download it
Not sure if there is a fee to register

With a new EFI box there are things that will not work if it's not aligned with the car's can/canbus or other signals. How much communication from the original ECU is going to the rest of the car?
I would like to keep as much as possible working though, and already planned for piggybacking with a DET3+, it is very configurable and the original EFI is still in use.

Fiat configures the Engine ECU, Body Computer, Instrument Block and ignition key chip as a single system. The lock together at first power on. Removing or changing any component will stop everything else working.

Wait, is that really true? How can the Panda work with the T-Jet Bosch ECU when doing a swap, if that's correct?
The network protocols are the same between the bravo ECU and the 100HP the pin outs are different
An adaptor is needed to plug the ECU in, the ECU needs to be virgin
Been done many times.

Who first discovered and then developed a plug and play adapter
He has also uploaded all the information on GitHub for free

That didn't really answer my question, nor counterfeit the pairing info posted.
If the components pair on first start and "lock together", how come the T-Jet Bosch ECU work with the dashboard?
The TJET sends the same information down the canbusb lines as the 100HP does
So is read the same by the body computer

Fiat ECU boxes (engine, body comp, instruments cluster) all contain a chip (tech term ;-o) that's open when manufactured. When connected into the car and first powered on, they all lock onto the same code**. With appropriate tools, any box can be reset to zero ("virginised").
** I do not know what code they use, but basically they all become one unit. Fit another used box or one that's not got the code facility and the system simply won't work.

There are apparently two ECUs that are plug and play with Fiat systems, one of them is EMU Black. I figured out after some reading that they apparently adapt their own pairing. This guy has done a swap, 500 with a T-Jet head, and there is a description of the pairing procedure in the linked wiki.
People doing the Pandapter swap seems to buy altered ECUs?
Regarding the EpicEFI linked earlier in this discussion, I have found zero docs on pairing/immob support. Canbus support is built externally with ESP32, Rasp Pi or Arduinos.
You not got it
The Bosch ME7.9.10 ECU from the Fiat Bravo or Punto 120/150HP
Is a plug and play solution
The ECU still need to be vigin (wiped clean of the old key information) so when it's plug in it reads and write a copy of the key code from the body computer
The Pandapter requires a virginised Bravo ECU to work plug-and-play.
The Pandapter simply converts the ECU pinouts for the 100hp ECU body loom to the Bravo ECU (including a couple of wires that aren't in that loom at all on the 100hp).
If using a TJet from a 500, you either need to swap the engine loom to a Bravo one, or change the engine loom ECU connector to suit the older ECU.
It is possible to avoid using the Pandapter by changing the body loom connector plug and pinouts to suit the Bravo ECU but its a pain to make it look tidy and its easy to introduce a really hard-to-find mistake (especially if you're colourblind - guess how i know that!).
I don't have any information on the other non-FIAT ECUs though.

I think you are the one not following along.
The ECU must be reset to work with the BCM. That is not a simple I/O pin bridging. So tell me how the ECU is reset, or virginised if you'd like, if not people are buying a whiped ECU or buying it as a service.
Via software
ABRITES Software Package for FCA vehicles
Is one solution known to work
MPPS, KessV2, FGTech Galleto may work
For a one off take it to a ECU repair company and ask them to virginize it, they do it day in day out
