The 575M came with two types of Motronic ECUs, three pedal and F1. F1 ECUs can be reflashed (off the car) to act as manual ECUs or manual ones can be fitted. The instrument panel also needs to be told that it is working with 3 pedals rather than F1.

The first conversion done by Wil involved transferring all the parts from a 550 to a 575, including the transaxle. He did not initially realize the 575 transaxle was upgraded from the 550 since the cases are virtually identical, but true pro he is, figured it out quickly.

Trevor reflashes 599 ECUs to make up for software issues coming from the factory on all 3 pedal 599s. He also can reflash ECUs for all models to improve performance and make it harder for CELs to appear, especially with headers. He can also make vanilla 575 ECUs compatible with HGTC TCUs or reflash the TCUs to add HGTC capability. Mine has Trev's reflashes and my vanilla ECUs work fine with my HGTC TCU. The HGTC TCU essentially uses 612/Superamerica F1A software, less the F1A selector.

 

yea, I will. But having owned a shop, I am sensitive to calling on professionals and wasting their time until I am ready to pull the trigger. I like to collect information and make sure I have synthesized all of my questions into as short of a conversation as possible, again being sensitive to their time.

 

No, you definitely need a reflash

 

You need a reflash or new 3 pedal ECUs, which are pretty rare now.

 

I’m surprised in this long thread someone hasn’t made a checklist?

 

This is very true. We’re going off topic here, but whatever…

For the 360/430/575/612, the ecu’s all came from the factory with the code to run both f1 and manual. In the simplest ecu correction, you’re really just changing a few bits in the code to swap modes over (there’s obviously more to it if you want the various upgrades that are available now). The 599 is different though in that the f1 ecu’s never had the proper code to run in manual mode, and it turns out (after Trevor’s dissection of the code) that neither did the factory manual cars. They just use a lightly hacked version of the F1 software to run without error codes. So for the 599 conversions, there is a tonne of changes that Trevor does to make the 599’s run like manuals do for the other models, one of those things being the way the ecu’s deal with the rate of decay in the engine speed during gear changes. Trev initially thought the function was broken, but it turns out that chunks of the code just isn’t there, even for OEM manuals.

I’ve tried a few different iterations of the rev decay management, and it’s clear that a lot of it comes down to personal taste as to how smooth you want it. For me, i want to to be drivable, but aggressive, so the current version is a bit too easy rider for my tastes. What I’m trying to get @360trev to do for the next version is to have the gentle response in sport mode, and the agressive engine response in race mode. This is all far too much detail for a thread about 575 conversions, so well done if you read this far. [emoji16]

Trev has even done some of the same rev decay management on the 575Ms he has reprogrammed for a few of us. Now no need to lift the throttle on Normal upshifts to smooth them out. Tricks Trev learned on the 599 worked on the 575 as well.

 

thank you for the detail

 

I dont think you can explain emotional purchases in a down market so easily.

The Belgian car is ~$220k once here and it is replacing a lower mileage Titanio car he said. So the buyer wanted blue, and that is an emotional driver, not a logical/financial driver.

Vantage's car was too low, but that can be down to many issues such as (1) non-CARB car (2) more common spec/color (3) lots of miles and IMHO most importantly (4) not the right people in the room that day.

In a soft market, there are not dozens of buyers anymore (and the perception is that there are a lot of these cars as there is ALWAYS a new one on BAT once one ends). So if the buyer pool is thinned - the above result can be boiled down to as simple an answer as there was only one real bidder in the room that day.

As we keep saying, this is not a good time to sell a luxury good as the market is really unpredictable and at auction it comes down to having at least 2 bidders to drive each other. One bidder may really want it, but if there is nobody else to drive the price up, many times it will stall or RNM. That one bidder may have gone to really high bids too, but once it stalls, the psychology changes and even that original bidder starts to second guess.

This is why frenzied auctions drive stupid prices. Monterrey drives the frenzy (drinking, ego, friends, competition). BAT does this too - sometimes. But right now, not a lot to be excited about for most of us from an economical standpoint.

 

I know, color and seats…but this is a strong showing so far for F1, especially on this platform!

7000 miles, too, plus all the extras. Too early for 19" wheels. They started being available right around the time this one was built. Giallo looks great.

 

seats seats seats. Although the Sparco/575 seats are easier to source aftermarket. But they do drive price.

 

Hmmm, have a source for me?

 

Good luck/get in line. I have been waiting for a set in the right color for 3 years now. Fortunately the 360/CS/early 430 carbon sport seats are nearly identical (only the shape of the seat belt hole being different), so I am using a pair in the correct color as hold overs.

 

Ahhh, well. I’m really not 100% I’d give up the Daytonas to be honest

 

Can they be directly from Sparco? I had a few sets back in the day as we were a Sparco partner. If so, let me know and I will see what I can do. If directly from Ferrari, I have no source.

 

Each his own. My car came with daytonas and I found them awful...too plush, too high, lack of good support for my frame. Felt like I was sitting on a (very expensive) italian leather chair. The sport seats are not plush but feel great.

 

I was (and still am) looking for medium or large, black with red stitching to match my 575 interior. In the US I found large was the most common size followed by medium. In europe you can occasionally find a small size but there there were more mediums to be found (though still large seems the most common from the limited sample I can tell).

Not unless I am mistaken (Tax feel free to correct me) the 550B and 575 sport seats were identical with the only difference being an extra line of stitching down the middle of the seat cushions.

I am 6'2" with a long torso so with the Daytona's I would sit looking out the upper edge of the windshield (where its tinted ). Also, I am also "normal" girth so I would not completely 'fill" the seat between the cushions on the Daytonas. The only issue I have the the sport seats are my shoulders are slightly tight (Large sport seats)

Interestingly, the 456M seats are similar plush but are slightly more "bucket" in shape + the higher roof means I don't have a similar issue.
