Transmission problems

[ChrisNico]

I live in London, but have my QP taken to Sportsitalia, 2 hours away, because I trust very few other garages to sort out problems like this. I had a similar situation, and Matt kept me appraised throughout the ordeal. The car has behaved impeccably for the last year or so, since the clutch/gearbox issues.

Well, one is 15 miles away and the two you've suggested many more than 15, so...



I think it's just air in the F1 system somewhere, it was just reverse missing until I started to tinker around with it.

The bigger issue is what went wrong with the clutch initially. I calculated clutch wear to be at 53% using the closed clutch position formula, so potentially not a new clutch as I thought...

...Unless someone has tinkered with the NCCP value. Have you had the car since the clutch was new, and have only competent-with-F1-transaxle individuals worked on it?

Just a little update to this. I had Bill from Supercar Italia come down and look at it and he couldn't get it going again as the values couldn't be adjusted by the machine so it was trailered to their garage in Kent.

Let this be a lesson to each and every one of you, do not tinker with the clutch settings unless you know what you're doing! This could be a costly mistake , but it seems like it's in good hands with Supercar Italia, so hopefully it won't be too long til it's back on the road; I've missed it dearly!

Transmission when they play up is a painful task to sort. Agree, don’t play with settings.

This is the issue with generic scan tools have these capabilities in the wrong hands. If there is a button, people press it. Same as the GT/QP handbrake calibration. Techs know if you cycle it the chances are you will knacker it and thus manual adjustment is the way forward.

To be fair, you had a lot of issues prior to you 'tinkering'

back to O.P. Did you get the gearshift / clutch issue resolved?

I haven't been around much as I had a kid, moved house, new job etc, but to answer your question no this has not been resolved yet.

Almost unbelievably, Supercar Italia still have my car and I've not heard from them in 5 months.

I've been meaning to get to the bottom of it, but since moving away and the little'un taking up any spare time it's just gotten away from me.

Needless to say, do not use Supercar Italia for anything! Hopefully if people Google their name this thread will show up.

Also, reading this post I made in October '22 again did make me laugh. But not in a good way, I hasten to add...

Assuming you want progress and ability to drive and keep the car, consider getting car shipped to SportsItalia. They are not magicians so cannot heal all woes, they do care about cars and offer honest appraisal and solutions. Even for a baggy old sh!tter like my 2006 QP.

WOW that really is bad, if they can’t fix it they should be handing it back not just letting things drift.

Has to be worth a call to one of the highly respected independents that are often referred to on here.

I have heard hints of someone in Kent who has let people down and now assume it’s this guy, so good for you for naming and shaming.

I guess the problem is no one like to be lumbered with someone else’s problem so an honest chat with people that might be up for the change has to be the way to go.

Good luck - hope it gets sorted soon

I know what your problem is - your TCU is bricked up. I also seem to remember that you ended up buying a new TCU from Maserati on the advice of SupercarItalia. When ScI installed the new TCU in your car it didn't solve the problem either. The reason is that your new TCU has been corrupted too. How can that happen you ask - it's very simple. When you change TCUs with the help of an SD3 factory diagnostic tool you download quite a lot of data from the old TCU to the new one. And that's precisely how your new TCU's software was corruptied without ScI knowing it.

I went through exactly the same pain in May 2024. Tried to run fast shift gearbox adaptations with a dodgy copy of Launch at home. Bricked up the TCU. Car would not start as the clutch would not open. Solenoid would make a buzzing noise, making a well known and respective specialist on here to think that a TCU transistor was burned out. Purchased a good used unit and swapped over. Car started first time, run adapatations and all was good. Run the Maserati procedure to swap ECUs with the help of an SD3. New TCU suddenly becomes bricked up too. Solution - open both TCUs - my original one and the used one. Find a good, working TCU of another MC Shift car. Read and copy the software off the good TCU. Re-flash the two bricked up TCUs with clean software off the working car. Do not use the factory procedure for TCU swap. Set up the clutch and gearbox parameters as if the car is new. Go out for a drive...

The only negative in the whole saga - the TCU loses the data which corroborates the mileage/engine hours stored in the Engine ECUs. Given that there is no other way to solve the problem, it's a small price to pay.

Let me know if you need more information.

P.S. Stradale software can be flashed on normal TCUs - wonder if it will have any benefit or it will simply bugger up the actuator...

The Stradale actuator is described as mechanically different in the brochure, removing the need to hit neutral to execute a shift.

In addition system runs at 70 bar rather than the 50 bar of the standard (in race mode only), and so there is a fair chance it will exceed the PRV pressure on a standard system.

I have seen the drawings - the standard actuator is also bevelled forgoing the need for neutral in MC mode. Not as much as the Stradale one though, so yes, I am guessing it won't be as good. And the Strad one has one less seal, so you get less friction and more inertia when the rods move to execute a shift, thus speeding up the process. As for the PRV - that can be swapped over... Anyway, it's academic - easiest thing would be to just fork out the £6.5k for a Stradale actuator and swap it over, while having the TCU reflashed.

Back on topic ...

I am realy hoping that ensignia can solve his problem and get his car back on the road and away from this garage...

Like I said - the brochure says it is different. As for the PRV, of course it can be changed, if you drop the gearbox.

If you knew, I’m not sure why you asked.
