I lowered my car with the H&R springs
After the work done I get CATS error on display
Do I have to reset the CATS system? What I can do to avoid this problem?
I already checked all connectors but they are all in place and in good condition
Do I have to run a TEST MODE on the display in order to read the error code?
Thanks for any help

 

...I lowered my STR with H&R springs and received no error codes and it's safe to say they have been thoroughly exercised and work perfectly

 

I lowered mine as well and got no codes. Did you do the install yourself, dealer or independent shop?

 

professional garage
The only thing is that they switched on the car (key position II) with the damper connectors disconnected
Do you think I need a reset?
There is any way to get a specific error code? (module/failure, fr damper failure, accelerometer failuer ecc ecc)
Thanks for any help

 

Not very professional to do that.
But, being professional, they no doubt have the dealer-type tool to sort it out- right? IDS will do it, surely?

 

They've got BRAIN BEE ST6000 upgraded but it doesn't communicate with our OBD
they asked to the assistance, but they do not have any idea
Should be that there is an error in OBD port
Well see
I think that in short time I will drive to a Jag *******
But I'm very impressed about the car......I'm quite scary that reset the CATS, will make my set-up worst

I don't know

A) leave with the yellow light, but very happy of my setup
B) try to reset the CATS and probably loose the perfect setup I'm driving today

Never got the speed I get today out of the curves....

 

Well..... you can easily cause the error again
I don't think you'll wish to

 

If you noticed a definite improvement after the install in handling then your CAT system is prolly working the way it should. The error code was thrown when dimwit turned on the ignition with the CAT system disabled as in disconnected.

I don't believe an off the shelf OBDII reader will clear the code and a dealer will have to clear it. Please don't refer to the Jaguar dealer as "*******". We have a number of Jag Techs who are well respected here and they offer us excellent advice.

You will not loose the "perfect setup" you now have when the code is cleared. Now go enjoy the friggin' car and keep the rubber side down.

Capiche...

 

Thanks for your help
Here in Italy/Swiss we refer to JAG dealer as ******* because they double the prices of spare parts
So we source these parts abroad, Germany and mainly UK
And then we use professional tuner than official Jaguar to mount them
I am very lucky to have one of the best tuner, and the developer of the best tuning software in Europe, so Jaguar dealer always help me due to the fact that they are customers of my tuner (including paramount)
But spare parts are sold so expansive.....
thanks again and I will revert soon

 

There have been a bended pin in the front right ammo
Now all is working perfect

 

so where are the pics?!

 

tomorrow I will take them and post them

 

cant wait to see......I still need to lower mine, but still to cold out.....How long did it take you to do?

 

in hours, not so much (3 hours)
But to take the front ammo out I have to unbolt the lower arm, loosing caster/camber setup
So I spent a lot of time to match the right setup
But I spent a little more because I made the following
1) new H&R coils
2) new front lower arms
3) new sway bar bushings ( front/rear)
4) CATS ammo renewed (20% stiffer as standard) and shortened to match the lower springs

This took a little more but now it's all ok and perfect

 

Let me make sure I understand your statement here.

Your local Jaguar dealer seems to over charge for parts so you source the parts from somewhere else. No problem there. Everybody wants a deal.

You have a "professional" tuner that is the best in the business and you are lucky to have him available to install your outsourced parts. He is so good he has developed the best tuning software in Europe.

He then installed your outsourced parts and managed to bend a pin in one of the shocks and render the CATS system inoperative. He couldn't read the codes to figure out what had happened even though he is the best software developer in Europe.

Are these accurate statements?

When you do revert please do so into a Honda or a rapidly accelerating Toyota.

 

Not at all
"I" bended the pin 'cause I careless plugged the ammo to the system
The Brain Bee OBDII system my tuner has doesn't read the Jag System
This is not a big problem because Jag it's not a "sporty" and tuned car here in our area
One time they have all the german and japanese, it's enough for 90% of the job
And the engineers has no time to dedicate to solve my problem because they are busy in developing the new protocols EDC17 for the new VAG cars

At the end I used the Range Rover dealer system to read the codes (for free :-) )
We reset the gearbox software too with the Rover diagnostic

Just for your information, after looking one of his car in the italian Porsche championship,
Porsche AG contacted my tuner to ask him to aid them in tuning the race cars (this is a real proof of his skills)

And then the last info....... I can use his Rotronics 4X4 1000HP dyno to test and tune my cars evrytime I want, so, after the ammo setup I will start with the engine (Kenne Bell and so on)

I don't think it's a bad situation and my car it's better day by day
But I have other jewels I have quite finished to tune, the R it's only the last one.......

IMPORTANT NOTICE: with CATS inoperative the car reacts better than with CATS,
More precise traction and turning
I think I will organize to switch off the CATS with the S button on the gearbox

 

Stating that the STR does not handle properly because of Jaguar design then later finding you didn't even have a properly-functioning car (as you say in https://www.jaguarforums.com/forum/s...956#post177956 ) is really not helping your case.

 

sway bar it's already changed, including new bushings
The car now is "like new" all the main bearings and bushings are changed
The ammo are upgraded, the coils too
There is no play or wear in all the components
Camber caster and all the angles are correct
The problem is the CATS software and the Jag project
I mean that Jag it's not a engineered as a "sporty" car in european style, it's more like to a "muscle car"
Comfort it's preferred to stiffness, this is common to the new Kr I tested yesterday
A lot of smoke from tires but very poor handling
To solve the matter I will play in the next days with angles and disabling the CATS
But I think I'm speaking about problems that in the States are not problems
I tested in the past BMW and Merc in the the States and compared to the same models in Europe and they are completely different in handling

 

So why would Jaguar fit CATS to the STR?

And why did they make the STR stiffer, a harder ride, harder seats, and so on? In this process they had to fix the rear seat in position, a big negative for many people. How do you fit all that into your reasoning?

Are you saying that CATS, stiffness, hardness etc are to make a muscle car?

 

Sorry for my english, but it's the maximum I can do
I have noticed during times that States car/bike market and European car market go on different ways

this is why Europe have
Formula UNO and States have INDY
DTM and NASCAR
WRC and......I don't know the parallel
Mugello and Laguna Seca

I think that with this examples you get the thing I want to explain to you
There is a different way of thinking and feeling cars and bikes

Jag is selling a lot in the States and is setting up his cars aiming to their main market

This is why Jag is not considered a sporty car in Europe but a luxury family car
I have bought this R type 'cause I like the look of this car but the ride is.......I have no words to say (the new K R I tested last week it's the same)

Last year they invited me to test the New Corvette and I get the same feeling I get from the K R
They are not in my way of driving
Powerfull engines, but handling it's very poor

But I like spend a lot of time and money to my cars in order to get them unique and feeling like I like

If I can explain to you how I act with my race cars and bike you can understand much more my idea
If I have a budget of 100
70% is for the Ammo/Coil/swaybars/tyres diff ecc ecc)
30% Engine
you can have a lot of power but the most important thing its to have a car that can use this power

CATS it's a perfect setup for an European daily driver only in the case he is not used on sporty cars and pushing the car to the limit in cornering

CATS it's not predictable because sometime it's soft when he has to be stiff
It is not so quick in rapid direction changes
When you have the weight on the front external tyre it's not allowing the rear tires to follow the bend and you feel less traction than without CATS operative
But I think these are feelings that you get only when you are driving to the limit
Another big limit of S type is the weight balance
I would have preferred a more central engine position
I think I will solve this matter too in the next year because I will have to see how to balance the setup a little more
