Hi all, noob here.

I own a Fiat Panda 100HP and managed to get myself pretty much everything I need to do a swap with a TJet 150HP Bravo engine. Looms for dash, engine bay and engine, body computer, ecu, clocks, fuel pump, turbo, intercooler, more or less everything.

Question for you wizards, Can I virginize my Fiat Bravo ECU and put it into the Panda whilst using the Pandas body computer and ignition key? I know that adding a virginized ecu is no problem but I mean would there be issues for the ecu and bcu communicating with eachother?

Let me know your thoughts.

Does it have an ME7 / Motronic ecu ? If not , I dont think many people can help you

As far as I am aware, the its the me7910. I will confirm tomorrow morning but think that's it

Definitely an ME7910

Is it possible to virginise it and use the ecu with the body computer from the fiat panda?

Anybody with any thought about this scenario? Not asking for any files or anything. Just wondering if the ME 7.9.10 would be ok to interact with a bcu from a different car (although both are Fiats)

Guess I will have to do some experiments...

I will try see if I can make a patch cable that will come from the Pandas body loom to the ME 7.9.10 and virginise the ECU. Will see about what combination of tech I need to use.

Anyone with any thoughts? Was thinking Immo Decoder along with Kess/FGTech programmers. Anyone think one is better than the other for an ME 7.9.10 or other programmers?

Of course I will need to do this off the car and crack open the ECU.

I would like to help you but I dont know anything about that ECU so I cant, others seem to be occupied I guess.

Search my posts around here on how to virginise ME7.9.10, one member recently had a good success following the procedure. Never used any of the existing tools for this, but I know for a fact that some of them butcher the EEPROM in the process.

As for making the ME7.9.10 work with another BCU - chances are slim, even the different ME7.9.10 use different CAN message IDs, some short, some long, different sets, and all. Even though 100hp is a Bosch (IIRC), this does not mean much. Two solutions I see - find the dash / BCU from the donor car too and swap that in along with the rest. The other one is not for the weak ones - reverse your original 100hp CAN message protocol, do the same for the ME7.9.10 ECU and make an Arduino or similar gateway / translator.

But, having said that, I know there are people that did this kind of swap, though not sure if they did not go stand-alone. Try it, with a little bit of luck both your systems (BCU and ECU) may use the same / similar set of messages, similar enough for most of the things to work.

What you are actually planning is one of the options I consider for a future project that I will certainly do at some point, all depends on the availability of vehicles on my local market.  

I happen to have the BCU and cluster along with barrel and key, looms for dash, BCU and ECU. But prefer to see if the ME 7.9.10 will work by just virginising saving me huge amounts of hassle as the looms are made totally different unless I got the looms from a 500

Another thing I'd like to note is that I also have the BCU and ECU out of an Abarth 500.

Another possible option I'm thinking is that the 500 and Panda share a lot of things such as chassis and even engines (169a3000) but I've heard the 500 uses the ME7.9.10 non turbo. I am assuming that the BCU is the same however on the 500 and Panda. If the Bravo ECU and the Panda BCU cannot communicate, the what I can do is get the BCU from the A500, virginize the Bravo ECU and try that.

At the moment though I've no programmer so suggestions for this ECU would be greatly appreciated with a cookie...

If you set up me7.9 right, or enable development mode you can run a turbo with non turbo ECU.

As far as I know, the ME7.9.10 has all of the details for a turbo in the non turbo 500. Guessing you can always play around with that if you ever did wanna turbo a non turbo 500 but then sure get an Abarth 500 lel.

If there was a definition file then it would make things easier but if its a matter of hacking away at the hex code myself then i am screeeeeewed. Was reading up on woj's posts last night, especially the one where you posts the C code of which is really confusing for me (programming background but never use hex programming) but still trying to decipher how the hex code works.

Thanks woj for those posts by the way, they are really interesting  ;D
