Look, we'll easily settle this.

I'll come down, you can do a stock dyno run. Put a box on and do another dyno run.

For my trouble I'll just go home with the box on!

Be careful you'll get accused of trying to bribe me lol

According to Autocar (22nd January) who dyno tested their long term Seat Leon with the same 2.0 litre 150 bhp engine they got 160.2 bhp and 259 lb / ft torque (Surrey Rolling Road). With the comment "VW Group cars usually develop higher outputs than claimed". Even so, achieving 196.1 bhp / 327.8 lb / ft is quite an impressive improvement.

Map 4 plus 1 produced the figures above

 

Andrew, I do an awful lot of mileage. Is 4 + 1 a very aggressive setting or is it a fairly "sturdy" map (if you get my meaning)

It's the flat torque curve which I think is most impressive, that thing would be a quick little Golf,Octy,Leon,A3.

In fact, what's the peak torque when set to 4 + 1?

The peak torque was 327.8/9lbft ..

We did run another file which produced 194.1bhp at 3396 against the 196.1 at 3491.

The 2nd file also produced 327.8lbft but at 1884rpm against 2015rpm produced by the file used in the graph above

I don't know a huge amount on chipping an engine, but I do recall a conversation with a friend a couple of years ago on the subject.  He worked in the automotive industry testing engines for manufacturers.  What he told me was quite interesting.  Yes, it is relatively simple to increase the performance of an engine, especially the diesels by remapping the computer. But this would have an effect on the engine, such as cooling, I think he also said something about  the exhaust. Therefore the radiators, intercoolers etc are carefully matched to the engine and they test them (to destruction I believe), to ensure they are good for the duty cycle they are designed to perform. You shouldn't just "turn up the wick" without modifying the hardware to suit.  Basically, I was lead to believe that chipping is not good for the engine. He also said something about worse emission too, but I can't remember much detail on that. What he said sort of made sense to me.  Is there something I am missing Andrew@DTUK?

Lets try and keep this on topic shall we?

any mods that increase the output of the engine are obviously putting more strain on components; I think that's pretty much accepted by everyone.

It would be actually more accurate to say politely you have no idea, you are missing the objective of the post... Are you interested In actually tuning your car?...

 

From what you have posted above I suspect you have little idea...

I was very interested before until I spoke to my friend but I became concerned about warranty on a new car as well as the technical uncertainties.

Hi ssfan,

As with any form of tuning you are going to place certain components under greater stresses, but most tuners take advantage of the tolerances the manufacturers leave behind .. So as long as the car is looked after you shouldn't have any more issues than you would of done in it's standard tune.

I was very interested before until I spoke to my friend but I became concerned about warranty on a new car as well as the technical uncertainties.

In fairness, and to answer the above... Technical uncertainties are negligible from the build of the engine as it is a well established platform.

 (From VAG) point of view... So I would say 'no worries'...

 

Warranty is down to  your supplier I'm afraid...

Back on topic.............any body who understands..........am I wrong in saying that this is a very smooth looking graph and that it seems to be a great result from the 150CR engine ???

I am trying and failing to test my PD140 to destruction !!!

 

I got it remapped when it was new in 2006 (180 bhp & 400nm approx) it has the so called "weak" DSG box and yet here it is, still storming along 621,000kms later !!!

I share your interest in understanding the graph and, of course, it certainly seems to me a great result but I'm a newbye at reading dyno charts. So I'm adding a couple of questions.

 

- How easy is to module on the throttle, given the massive increase on torque in such short a rpm range (from 1500 to about 1750)?

- And, given the decrease of torque after 3K, at what rpm would you guys advise to shift gear?

Am very interested in this. Please could you confirm the cost, including fitting. Any idea of the impact on mpg?

I would say with that amount of torque available I would rarely see above 2.5k (unless you where racing for honours on the motorway O:-))

Don't think I've ever taken the engine in my Octavia above 2,500 RPM!

Tuning is probably not for you if you do not use half of the performance range already available.

Unless on tick-over I'm not sure mine every dropped below 2,500 ! certainly not on gear change anyway, could have been why I done two turbos and DMF in 60k miles, sure was fun though.  Hence, the DSG on my next one a free reving petrol.

What a pity

 

Seriously, at least on older engines higher rpms were the main tool to "keep it clean" (EGR, and DPF). So, when the engine is warm, I rarely shift below 3K and - on the highways - I was more often on 4K

 

On the old PD you could fill the 4K wall, hopefully the latest CR has something left passed the 4K...

 

And... no whatsoever mechanical fault, clean turbo and EGRs, no troubles on DPF regen

 

When I gave the car back (about 180000 Km) "she" ran way better than new
