Slow engine response when blipping the throttle

Which model? My 360 is very quick to rev when blipping, you have to be careful not to get a "zing".

I agree; for me it's almost impossible to heel-toe the 360 because the throttle is so sensitive. The technique works much better on the 348 in my opinion.

 

If you don't already have a Tubi and de-cat that will make a significant difference to throttle response. I imagine the biggest difference is in removal of the cats. If you need to have cats where you live due to legislation then hyper-flow cats should give a similar improvement in throttle response.

When I had my tubi and de-cat done on my '97 355 I noticed this improvement in throttle 'blippability' immediately.

I don't want to give the wrong impression...it took a few tries to get my foot calibrated, but it works great now. When someone drives the car on the track who is not as used to it (like my son) he will occasionally "zing".

Andy,

my 97 spder had slow throttle response too. Adding the Tubi and new cats helped. However, the single mass air flow meter on our car is the culprit. The thottle response on my 95 355B was 10x's quicker. The throttle response in the 360 is 20x's faster and very very quick compared to our cars.


It's not you...it's the car.... What I do is double Blip...when the revs are up it has better response like you mentioned.

Hi all,

I resurrect this thread because I have been experiencing a weird blipping issue with my 99 360M 6sp. Heel and toe is fantastic, the noise that the Koenig exhaust makes is nothing short of spectacular. However, I also blip the throttle during upshift; I find the revs dropping too fast (due to design of the flywheel I believe?), so I blip the throttle in upshifts when I gun it to ensure a smooth transition and avoid unstablizing/jerking the car.

I realized that there is almost no throttle response between 2nd and 3rd gear while the clutch pedal is depressed, I have to wait almost a second in neutral/clutch disengaged in order for the throttle to regain response. Anyone know what would be the cause of this? There is absolutely no problems with other gears in regards to upshift blipping. This issue also only occurs in the higher rev range around 5000rpm to 7000rpm (I almost never go higher than 7k, afterall its a 14 yr old car).

Any help appreciated, thanks in advanced.

 

Hi Andy,
I have had the exact same problem since purchase. I searched for a long time for a manual shift 360 spider because I enjoy shifting gears myself. But the engine just will not rev up quickly when heeling and toeing or double clutching. In addition to not getting a fast enough increase in revs there is a loud cough or what sounds like a "backfire" from the front left area of the car.
I have taken the car to two Ferrari dealerships, one opened the exhaust bypass valves to "increase flow" the other reconnected them, neither had any effect. Next I had the accelerator potentiometer [the car is drive by wire] checked and is apparently OK. Following this I had the throttle bodies cleaned and reset and replaced both air flow meters [$790]. This last has slightly improved throttle response but the "cough" remains.
My belief is that the car is somehow set up primarily for F1 paddle shift as I have never heard any of my friends with F1 shifts complain of this problem. Also very few owners with 3 pedal cars seem to notice throttle lag as almost no one, in the US heel and toes or double clutches. Hope the above is helpful.

 

355s are known for having a "sticky" throttle. Are you sure you're not just meeting resistance when you press the pedal?

 

My 430 also seems to experience a similar issue. Throttle response is slow and somewhat inconsistent making heel toeing difficult, especially given how great the CCBs are. A blip of the throttle on downshifts produces inconsistent results. And blip is not really the right word. It requires more of a stab. I thought I just needed more seat time to calibrate, but it has not really improved as much as I would have expected. I have had the dealer look into it and they did reset something which made it feel a little bit better, but still not as good as I would expect.

I don't think it is a lack of skill thing either. I heel toe my 911 very smoothly on both the street and track and can adjust to different cars fairly quickly. Granted I have a lot of seat time but I can smoothly heel toe at any speed in any gear in mid turn without much thought. With the 430, I really have to concentrate to try to hit a smooth downshift and i still can't do it consistently. What am I doing wrong in the 430?
