Tuning Stilo 1.9 JTD 115 - Re-map or superchip?
Something strange there thenas mine has no trouble at all with emissions (and has an AT generic map). They give a full refund within 2 weeks but outside that I'm sure they would have been happy to install a lower performance version at no extra cost. :chin:
A generic map is based on a good running version of the same engine. You can still have different variants of the same map (such as one based on performance or economy etc.)
A live map is done in conjunction with a rolling road and requires a lot of skill. These types of maps can generate the highest possible gains but they also have the potential to create the greatest number of problems. This is particularly true when engines are mapped that already have existing defects. The map is also dynamic in the sense that if something which affects performance is changed then you should really have another mapping session.
Good generic maps are immune to these issues.
He did call the guy who did it, he just said there was a fault with the car and there was nothing he could do.
So if someone had performance parts installed, exhaust, induction kit etc. The car would probabely benefit more from a Live Map, resulting in an excellent increase in performance? I guess the fuel you use in it would make a big difference to a car with this sort of remap?
Where as a standard setup car would benefit from a generic map resulting in not so good increase in performance but better reliability? And I guess this car would not be effected as much by the fuel used?
Sorry for all the questions but thinking about having a remap on a new car in the new year.
That's generally right but you shouldn't assume a live map will produce poor mpg (depending on the tuner it may even be better) and also remember generic maps offer a massive improvement, over standard, anyway which is very often combined with better 'driveability'. Personally, I'd say live maps are more for track day usage and out and out enthusiasts who have modded their motors quite a bit.
As we all know gentle use of the right foot is extraordinary difficult when all that extra power is on tap - so increased consumption is always to be expected (though likely still better than anything chip based).
When I said:
I didn't mean poor MPG.
I ment the quality of the fuel. I have seen a lot of posts about the poor quality of supermarket fuels. I'm guessing a car with a lot of modifications/live remap would suffer in respect to performance from using such low quality fuel.
If this is true what would be the best fuel to use. If I'm going to spend hundreds of my hard earned cash on a remap it would be stupid to use low quality fuel in it that only saves me a few pannies and impairs the performance of the car?

My Coupe is modified and live mapped. I would recommend running on the fuel of choice at the time of the map. Having said that, mine runs happily on 97 and 95 RON fuel. But having spent thousands on mods and re-map, why would I put cheaper fuel in, so I don't normally.
For your interest, this was part of an e-mail I got from Angel Tuning:
We offer engine remapping, the modern version of chipping which is the correct way to safely tune a modern diesel engine and is not a so called “tuning box” which simply dumps more fuel into the engine. With our ECU remapping you get smooth and progressive power, with improved response, that can be tailored to your requirements. Angel Tuning are able to offer tuning services at your location with our mobile tech team, who are fully equipped with the latest diagnostic equipment as well as a wide range of tuning hardware. Whilst we normally book 3-5 days in advance for mobile it depends when you book in as we can often get customers in earlier.
Our charge for the 1.9 JTD is £250.00 including VAT. This price includes the engine tuning work to add up to 35bhp, (60lb ft torque) pre and post testing, acceleration testing and travel to your home or workplace.
We would like to state that we are not the sort of company that tries to get the ultimate extra 1bhp at the expense of drivability just to look good on paper nor do we quote the power figures from a single dyno run set up to achieve a short term burst of power to win your business. We know from vast experience what these cars can take long term and our aim is to achieve the best combination of power, longevity, economy and as mentioned, drivability.
Whilst we are unable to give an accurate figure on the improvement in economy after your car has been tuned, most people get between 2-6mpg improvement on diesel vehicles providing your driving style and the speed you drive at does not change! As the engine is running more efficiently, the emissions are actually improved so there will be no problem at MOT time should you have the car at that point.
The ECU remapping we do is physically and diagnostically undetectable. Of all the cars we do, some 75% are either brand new (i.e. pre delivery for dealerships) or under warranty because of the stealth nature of it. However, we do understand owners concerns, which is why we offer a free* “return to standard” for any owner who is concerned about taking their car into the dealership with the modified mapping on.
ECU remapping is fully reversible, which means if you are unhappy with the results on the day, we will return the car to normal and thank you for trying us. After this, we offer a 14 day "cooling off" period** during which you can at least get the chance to test our work over distance and familiar journeys. If once again you are unhappy for any reason, we can either modify what we have done or indeed return the car to standard and give you a full refund. When you come to sell the vehicle we can return the car to standard for you free of charge****.

So you find no difference in the performance of your car when you change fuel with higher or lower Octane levels?
Is this because your car doesn't have one of those siesmic "knock" detectors that retards the ignition when lower octane fuels are used?
I thought most modern cars had a siesmic "knock" detector and thats why using the correct octane rated fuel for your car was important?
There may be a difference in the power with the higher octane fuel, but for regular driving I don't notice any difference. The car is so powerful, there are few occasions when you can exploit it, when you might actually see a difference.
Re-reading this old thread I realise that I never actually mentioned the fact that the re-map positively imporved my car's smoking issue. It was a real smoker, so much so that I thought it might previously have been mapped and even if it had not been, I was concerned that the re-map would cause it to smoke more.
Much to my amazment the re-map immediately reduced the smoke, by as much as 50% I would say.
PS. The man doing the re-map studied my map and confirmed that it was on the original map.

My 2 cents . . I tired one of those cheaper CHIP tuning boxes and saw NO increase in MPG nor did I feel an increase in the seat of my pants. Opted for a more expensive one (http://www.racechip.de/) and felt immediate increase in the seat of my pants acceleration, and ( if I could keep my right foot light ) in increase in MPG. Only (minor) problem I had was check engine light came on after first start when installed, but after resetting fault, light never came back on. Also box is adjustable, (but must be taken apart -2 screws)
