612 F1 to manual conversion

Paul- The F430, 575s, early 612s and early 599s all have Motronic 7.1.1 that uses the same Bosch hardware boxes and similar architectures. That does not make them the same ECU since the programming is completely different. An ECU is hardware plus software and the software is vastly different between an 8 cylinder F430 and a 12 cylinder 599.

Jason- Later 612s and 599s (from serial number 156938) have Motronic 7.3.2. There were interim 612s with 7.3.2 (F133H engines) that are pre-OTO. There are compatibility issues with other ECUs and the CAN between the two, but going manual may ease some of those.

 

Terry, I am aware of that, but the ecu is the same apart from the software, which can be changed.

Bosch part no is exactly the same for all. They roll out of the Bosch factory identical prior to the software being installed, only at that point do they become specific to any particular model.

As an example, what spec is this ecu? all those cars you listed have the same Bosch sticker, well apart from the 575 as it uses an earlier ecu than all the others.

Also I can find no change to the ecu used by the 612 throughout its life, they only come in 4 specs which are split into manual (USA and ROW) and F1 (USA and ROW)

Paul- The 575M uses 7.1.1 as well. Have not looked at the hardware edition. When those boxes roll out of the factory, they are not ECUs, just hardware looking for a fix.

Look harder on the 612. Motronic 7.3.2 for the F133H engine uses a different hardware box. Might be easier to find with the 599 since more 599s had 7.3.2 than 7.1.1. Not easy to find any info on what changes were made to 7.3.2 F133H 612s, except for the Motronic ECUs and matching other ECUs.

 

If we can pool our knowledge base then I am sure we can come up with a solution.

This particular engine/.ecu set up is new to me so I am gathering data and components on a daily basis now ready for when I need to install our 575 engine into our project car.

I am using the Ferrari parts database to work out the various spec options, I use the one on the euro spares website, which is the same I believe as Ricambi and Maranello Classic Parts.

Eurospares only list 4 types of 612 engine ecu split as per my post above, with no change over via chassis numbers during the model run.

From what I can find so far, its relatively straightforward to reflash the ecu, just a bit of software that is readily available online from a variety of sources and some cabling, and can be done in car or on the bench.

It will be a while until I am at that stage though.

It seems the change over of ecu was during the 575 model run as from chassis number 55769

There are only two ecu listed for the 599 which are either US or ROW spec. Plus 6 specs on top for the GTO dependant on which country they went to, so just software differences.

 

575M Motronic 7.1.1 DME Part No 181228. Have not seen photos of a 612 or 599 7.3.2 DME to see which hardware they use, but have not looked, either.

The ECUs on the 575M were updated several times, so not sure if they all used the same hardware box.

Jason- Wrecked 2010 OTO on E-Bay. Might be a fun project, but she does have a salvage title.

 

There is one available here in the UK as well, LHD ex Middle Eastern car, engine bay fire £15,000. I have had dealings with the seller, he is pretty straight up. I imagine the price is negotiable.

Happy to assist anyone abroad who may be interested in it. I have no links to the seller though other than as a past customer of his.

So, does anyone know of a converted 612 from F1 to stick-shift? If so, provide shop name.

 

I know of someone on here who recently converted a F1 612 to manual...

If it’s a shop you’re looking for, then Wil de Groot from Exoticars USA has just last week finished a 612 manual conversion. Definitely give him a ring if you’re thinking of converting. In fact his converted car is just about to go on sale, which will be interesting to see how the market reacts.

how things going after years

 

Brilliant. Was blasting about in the car today and honestly couldn't imagine the car any other way now.

Ferrari are definitely remaking some key parts now - when I bought my shift bars, they were the last set in stock, but more have just been accepted for an order, and the control plate which was on back order, is due to be available again in June this year. Seems like Ferrari are now tacitly accepting that F1 to manual conversions are a thing.
