I’ve some Forza 7 data to work with now, so I’ve been working on some tuning solutions.
There are essentially two calculators I’ll be refining.
FORZATUNE
The first is a slight set of revisions to the existing ForzaTune6 app to keep it fresh and functional. It is currently OK, but it does need a little tweaking to make it better.
ADVANCED TUNER
The second calculator is what I’ll call the Advanced Tuner. Without going into too many details, this tuner is a ground up rebuild in my typical calculator tuning process, and includes a fairly wide selection of custom adjustability to suit the individual users personal tastes.
Want to test some cars on the default setting Advanced Tuner?
Post your car details here and I’ll share what I’ve been working on this past couple weeks.

Stock Tune 2:18.126 dirty.
Fdog Tune 2:16.583 clean.
The tune didn't mention anything about toe settings or tire pressures so toe was left zeroed front and rear, and I took tires to 28.5/28 front to rear, or ride height, which I set as the standard Fdog setting of 4 clicks above minimum. Brakes were the same as stock, and left that way.
The car in stock form pushed a good deal, probably because of the front roll bar being in the low 30s. The tuned version still felt a little too stiffly sprung for my tastes but was a pretty drastic improvement over the stock tune. I couldn't run a clean lap with the stock tune, it would push out more than I could manage, and then would spin tires with little notice.
The 2:16 was good for 89th of 1920 times in the Sport GT Icons leaderboard.
Ride height is more of a problem.
Some cars, especially wider variations, will bottom out easily, and the adverse effects of doing so seem to be stronger.
4 clicks above min is a good starting point, but watch for “sparking” it’s a good indicator that you need more spring and/or clearance.
That said, a little toe tweaking will surely work, but it’s not something I’m focused on at the moment.
RWD -.1 or -.2 for stability?
FWD +.1 for corner feel?

2.17.851 Fdog w Open Brake Tune
2.15.687 Open Tune
2.16.115 Fdog Tune with a 2.15.5 decertified due to overshooting Spoon Curve. Your brake setup just doesn't get along with my style, it seems.
Overall my car feels much more on edge than yours. Your tune is a far more consistent drive when I have my braking setup on it. In the end I've loaded your tune with my brakes and feel a lot more confident in the car, and if I went back I'm sure I could outpace my current leaderboard time with my tune due to that comfort. 2.15s are good for approximately top ten(I'm currently 7th) in the FNF leaderboard at Suzuka, out of 962 times set at the time of this post.

Especially with the Lambo.
Fdog 2:20.669 dirty. Pushy but mostly manageable. Chalking the dirty lap up to rust, been a bit since I've played.
Open 2:20.717 clean. Twitchy, just on the edge of manageable but not a confidence inspiring tune. Tough to wrangle but did feel more willing to rotate into a set.
Fdog 2:19.997 clean. Much more neutral feeling after driving my twitchy tune. I'm not especially confident with the build for this car, or if this car is actually viable in A class as it currently sits, it may be better for the top speed tracks, we'll have to see. Overall your tune did wind up faster, and it also didn't feel quite as pushy as I'd originally felt though it was a little slow to find the apex.. In the end, i think I'd rather drive the fdog tune.
Fdog 2:24.719
Open 2:24.438
Fdog 2:24.354
Not a lot to say here, both tunes were pretty similar feeling and that shows in the times.

EDIT:
Also, I finally manged to run a few laps in that e36 widebody. I had tuned the car a little bit before I did the B class rivals event at Watkins.
Ran .6s faster after the tune. The car doesn't feel pointy enough and I didn't use the calc diff settings (I think I'm somewhere between 50-60 accel and 30 decel). Overall though, the car feels much more locked down, It really hooks up out of slow and medium speed corners now which is surprising.
Reduce the rear rebound in that e36 by a couple ticks and it should turn in with a touch more authority.
Kicking the caster up a couple tenths may improve mid-corner bite also.
