360F1 jumpy in 1st gear

Maybe if you fill out your profile,someone here can recommend a reputable ferrari dealer/mechanic in your area that could have a look and maybe help you with it. Cheers

 

Can you describe the problem better?

Car is jumping back and forth as if you are giving it throttle/no throttle/throttle/no throttle? The "kangaroo" effect? You are moving ahead and it does this and it doesnt seem to go away very easy? If so, that is by design and common.

If it is something else, sorry cant help

 

i dont have a lot of experience with 360's but i am curious how the car runs. is the car falling on its face and the ecu is telling the clutch to slip because the engine is thinking it is stalling,detonateing,skid control. some transmission problems are not the tranny but the engine .the other thing i would try is what happens when you push it even harder.do the wheels brake loose . i would like to know what you ever find out. forza frank

 

Here is the "kangaroo" scenario, which is by design and normal:

The 360 is throttle by wire; so realize it is extremely sensitive.

If you give a moderate amount of throttle from a stop or a slow speed (not wide open throttle, not 10-20%, but maybe 30-50%), there is a tendency for your foot to come off the throttle VERY SLIGHTLY as the car pushes your body back due to the acceleration. This slight release of the throttle (very small, maybe 2-3%, you do NOT notice it) can send a signal to the ECU that you want to decrease throttle.

This then slows the vehicle down, pushing you slightly off balance and forward -- your foot might then give 2-5% EXTRA throttle, sending the signal to the ECU to accelerate, which pushes you back slightly, and then cycle repeats and repeats .... You look like a fool driving down the road, bucking back and forth.

To get out of this effect, you either need to get off the throttle completely or better yet, give it MORE fuel so you can get out of this sensitive area of the power band.

To prevent this from ever happening, do not try to keep your foot at a fixed throttle position when you accelerate from a stop or slow speeds -- i.e. dont keep it at 40% when you take off -- instead, give it 40%, then gradually increase to 45, 50, 55, 60, until you reach your desired speed.

This is common if you are experiencing it and is the design of the vehicle. But I am not sure you are experiencing this because I would think the dealer may have figured out what is going on already and explained to you ... unless the service guy is new

 

This is right on and applies to the jerky F1 I often get in my 04-360 as well. To counter it, I have been focusing instensely on not only NOT lifting my foot under acceleration but applying more throttle to compensate the seemingly natural tendency to lift my foot somewhat. When I do it right, I've noticed the shifts are relatively smooth, even under hard acceleration.

i have found this to be the problem with a harsh suspension starting off at a rough intersection, and you look like a complete a$$ that doesnt know how to drive a 5-MT (or F1 in this case)
