ASR kicking in

[red griff roger]

I am getting a problem on my 360 with the ASR cutting the engine revs. It is usually on a track (sorry, Ferrari Experience Day) on the out laps (i.e. hot) and will run like a bucket of nails for about half a lap, then OK. I can get round this by turning on Sport, which I think cuts back on ASR. Definitely not wheel spin (dry and straight bits), and the other day was whilst joining the M1 behind a truck, so not going fast or revving much either. Problem is that it is intermittent, so hard to do a diagnostic, and in my experience, these things get worse, not better.

Very grateful for any suggestions of where to start looking?

Unless I've missed something why do you think its the ASR - could it be a coil failing ?

From memory the light on the dash :-)
Mine has cut in a couple of times but not generally when in a straight line, trouble is you can't really use sport on our crap roads ....

Does your car run the standard wheel and tyre size or have you gone up to 19s?

I found the ASR on the 360 was fairly intrusive. As you've found out putting it in Sport mode helps but there's not much else you can do other than turn it off. What tyres are you running?

Yes, this causes issues on the early cars.

Yep me too..... F430 wheels on my 2000 car caused a number of issues. Both early ABS (scary!) and ASR intervention and it felt like it messed up the rev matching for the F1 box although I'm also pretty sure that was just how it felt rather than it being a real issue.

The car also drove like it was on stilts, never felt balanced and the ride was terrible. I went back to 18" Challenge wheels with wider rubber and it transformed it into a go-kart.....

I believe the later cars had different ABS/ASR programming which sorted the intervention issues.
If you have an early car and are considering 19" wheels, I would see if I could try some first.

Thanks for the various replies guys:

johnnyreggae - the light on dash coming on with 'ASR'

Pau1 and voicey - I have stuck with 18", but have got two sets - the 'Starfish' running Michelin Sport, and a set of BBS challenges with Pirelli Trofeos. The ASR kicks in on both.

mike01606 - normally the car is a beaut handling, and the ASR is as it should be - comes on when I run out of talent. It is definitely not a case of kicking in because the wheels are spinning - on the straight, dry track modest revs. I only think it is a heat issue as it only affects the car for a minute or so and usually at the start of a run on the track - i.e. the car has sat for about 30min while I have a cup of tea. After the minute, it then behaves. It has only ever (so far) kicked up at the start of a run after sitting, and whilst hot.

BTW - it is a manual, so not a F1 box issue.

'Spect I will find out when it fails completely, and I have to buy a new ECU!

OK - it sounds like you do have a problem (as opposed to it being normal). Have you had the car connected to an SD machine to check for errors? Your profile says you are in Beds which means you're not too far from Ed @ Dove House (who kindly posted in this thread). An hour or so of diagnostic time might be money well spent.

May just need the ASR recalibrating.

Cheers for the thought Aldous, but yes I have had a diagnostic run. Unfortunately, as this is intermittent (and possibly the electrics really think there is wheel spin) nothing shows up as abnormal. I guess it will be one of those gremlins that gets worse until it really breaks, then I can spot it. At least the ASR has an off switch to get me home, although I would rather not drive around too long like this.

Reluctant to swap the ECU on the off chance that this is the problem.

BTW - thanks for the tip on Dove House. I didn't fid this when I was looking for someone nearby.

Not heard of this - how does this get done?

[voicey]

Do you do the FOC track dyas? If so then it might be worth asking whichever dealer is running support to monitor the ASR parameters with their SD3 whilst you go out.

That is a great idea! I was at Oulton yesterday, and wish I had thought of it. Doh!

Interesting reading this. Yesterday when I started up my 360 the ASR and ABS lights came on! Took the car a run and it never cleared to begin with. However, once car had been turned off and back on again, the lights have gone out.

When I ran it past a specialist this morning his advice was the Battery could be low so it needs a good charge. Plan to get the trickle on it for a few days now and try ensure the battery is back to full juice before a run on Friday.

Anyone else had this problem?

Also, the switches on the right hand side where Sport, ASR etc are. That rectangular panel where the switches are is a bit loose on mine, is there a way to secure this back in place?

Cheers

A healthy, fully charged battery is the cornerstone to worry free ownership of a modern Ferrari. Mine stays on a tender as much as possible.

As voicey says, more than likely battery........They need to live on a conditioner when not in use.

I had a similar issue on mine very recently. ASR ABS lights on when cranking.

It is caused by low voltage but on my car it wasn't the battery, it was the main earth connections on the back of the front compartment isolator and where they ground on the chassis.

Cleaned them all and bonded the two earth points together on the chassis (the main one is a single riv nut) and it has been perfect since.

Thanks very much Mike, appreciate that. My car is on charge as we speak. The trickle has a bit of a faulty connection on the positive wire tbh so going to look to replace the charge but I got it working atleast. Being a niave first time owner, I didnt realise the battery was such a big factor but lesson learnt! Hoping it is simply a case of my battery needed more juice

Remember that placing the car on a trickle charger isn't the same as a battery conditioner/maintainer, which is intelligent enough to keep the battery in top shape without feeding it with a constant charge. Plenty of info out there and ctek & accumate are two brands to look at. If you already have the car hooked up, ignore this post!

on the accumate when not on the road, and new battery. will try earth straps, but as this is only an issue when hot am not sure if this will be an answer,

Thanks chaps,
