hi
Was thinking of having my Audi A4 1.9 Tdi 2003 100bhp pd remapped this weekend. Have owned it for few months but i think it lacks power. ECU Remap guy reckon it will get to 140bhp.
Firm im going to is called Chipboost in Scarborough. Any views on them?
Will the remap shorten life of clutch,gearbox,engine?
Will car need to be serviced more often. current mileage is 98k and has been serviced on long life routine every 20k.
Any one had a remap done?
|
you really think a 40% boost in power to an engine thats done 98,000 miles is a good idea?

was told by the guy at chipboost that these engines are downtuned to be run in all countries, in all conditions and on poor diesel fuel. here in uk we have good quality diesel so this power gain is well within the engine parameters.
|
As AE says tho 98 is still 98
it will have a bearing or not as the case may be
what did the chip company in scarburger says about the miles? and any disclaimer due to legs flying everywhere?
|
|
do I read this correctly? this car has had four oil changes in 98k miles - he wants to boost the power by 40% and is wondering if it will have any adverse effects? That'll make interesting reading over in Technical Matters in a few weeks if he goes ahead.

If you want a quick car why not buy one, my old boss did the same thing on is newish but high miler passat tdi and stripped the cam belt causing little bits of engine to bend.Like normd2 says it will make interesting reading if you go ahead also what makes you think the diesel in the UK is good.

I would never leave services to 20K,
but
Lots of engine ranges differ only in the CPU. eg the later volvo 140 and 170 is in the ECU (I know the early ones are 10v/20v)
I would want to know what will be done at the car? And I would pop over to an audi forum and find out what the real differences are between the 100/115/130/150 versions.
It may be that the difference is ECU, injector or turbo. I would be more prepared to do whatever is done as 'standard'.
Has it had a belt/tensioner change? Aren't the intervals down to 40 or 50K now?
And Dont forget to tell the insurance.

I am not sure how "chipping" would cause the cam belt to fail - if the valve springs were fiddled with, yes, but...

think off the extra power being generated and all those likkle teeth having to stand it in an enviroment of x years x mileage and x weather
ive seen more cam belts broken on start up than actually when running

Yes, but the belt only has to turn the camshaft, so "chipping" won't directly affect the power the belt transmits to the shaft - strain on the drive-train, gearbox etc - yes.

Yup. That's because the strain on the belt is greatest at startup - somewhat counter-intuitive, that!

I firmly believe the manufacturers know best when it comes to achieving a compromise between performance and longevity. By all means change it, but by increasing one, you will decrease another. Understand it's a trade-off, and if you accept the risks, go ahead. I think it's particularly brave with 98,000 miles on the clock and 20,000 mile service intervals, but then it's your call. It's not just the engine either - you'll be asking a 100,000 mile old transmission and clutch to deal with a huge jump in torque as well. What's the torque margin on these components when brand new, and how does 100k of wear affect it?
As a more general point, I find it hard to swallow the "variable fuel and operating conditions around the world" line from these tuners. Yes, some safety margin has to be built in of course, but 40%?? I seriously doubt it. I could "chip" the Scenic to 160 bhp or more if I believe some of the claims, but I genuinely believe you get nothing for nothing.
The tuner is going to shrug off your concerns - they won't guarantee the mechanical integrity of your car, and will have made their money before anything goes pop.
Cheers

20K service intervals are no problem in themselves.
There are more powerful versions of that engine already - may be done by bigger turbo etc, but intinsically the engine should be fine.
Of course there's pretty limited opportunity these days to use such power anyway, so the vast majority of the time the engine will be running no differently to how it is now. Being sympathetic with the engine and drivetrain (gradual acceleration, not stamping on the gas) is probably more important as the mileage increases.
