In your own posting style: Wrong. Very wrong.

 

And I know this from personal and friends experience.

 

Please try reading it all again. You stated that Skoda will know. I know, from 8+ years of personally remapping diesel engines that it is possible to load different fuel map and config files, run engine for any length of period, then revert back to standard fuel and config files, clear to factory defaults, configure and there will be no trace of any changes.

Your anecdotal evidence from your friend proves nothing, and certainly doesn't imply that my statement is wrong. Merely implies they didn't obviously reconfigure the ecu in the way it is possible.

To try to fool a dealer is morally bankrupt and illegal....

Typical banal forum post. There is a distinction between talking about whether something is possible or not and actually doing it. Forums would be a better place all round if we didn't constantly get posts like yours.

I have never, and don't plan to ever remap or tune a car with the view that if anything goes wrong to reset it back to defaults and claim on warranty. In the same way a crime writer can storyline the perfect murder without actually committing one!

Excellent. Glad we agree.

I´ll try again..

Sorry for nagging, but is there any progress?

 

or haven´t you been able to get a hold of a car for testing?

I'm no expert, but I'm pretty sure that forum sponsors who perform re-map services have confirmed there is a detectable change (possibly a checksum) in the ECU following a remap.

 

Whether Skoda or the insure is dedicated enough to check is another matter. But again, reading on here over the years, I was under the impression that remap was difficult, rather than impossible to detect.

Correct, but not what was being discussed. A remap fuel file will have different Hex values from the standard that it replaces. What discussion was about was that if you first remapped, then went back to standard, it would still be possible to tell that the engine had been remapped at some point. Point was that if done correctly, there would be no trace if you reverted back to standard, there would be no trace that car had been remapped.

I Just want an exhaust for the RS.... Just some gargle and no consistent loud exhaust note when at cruising speeds. Only when you floor it a bit and in gear changes. Milltek is the right way to go?

Going from 170bhp to 200bhp is nothing like as big a jump as increasing a 220bhp engine to 300 bhp. 30 bhp I would personally judge as an acceptable technical risk, 80 bhp I would not.

The last four cars I've owned have been remapped, done loads of miles (at least 80k), driven hard and done track days with no issues. You say adding 80hp is too much? And how do you know that Tim? I had an ibiza 110tdi which I tuned and added another 75hp / 100lbft . In your eyes that is too much and unreliable?? Yet it did 105k miles before I sold it on.....various track days including the nurburgring and was still on original clutch, turbo etc. Oh and yes I had upgraded the suspension and brakes so hopefully I'm not amateurish! Yes your entitled to your opinion but if don't you don't want to tune your car then fine but why go on forums and start arguments. Andrew and shark are doing everything professionally compared to a lot of other companies out there but you seemed determined to put them down at any opportunity when , as far as I'm aware, you don't have any experience of their product.

I'm not going to get drawn into futile and stupid arguments here yet again - my last post on this subject was nearly four months ago - but as a qualified engineer - albeit not automotive - increasing the engine output very significantly without a ground up redesign and strengthening of key components conrods, crankshaft, drive train, pistons, liners, oil pump - both lubrication and cooling, even big end bolts etc etc  is likely to lead to trouble. Big trouble.  I don't need experience of a particular product or an automotive engineer to work that one out. Do it if you want......

I did. Compared to factory figures im running 104% increase in power and 71% increase in torque. Engine now has over 40,000 miles on. No issues to report.

I'm not looking for an argument either, just putting forward my opinion and personal. experience. Depending on the engine and how high you want to increase the power then yes l would agree. Vag engines are always understressed compared to a lot of other manaufacturers and having only ever owned and tuned vag cars over the past 15 years I have never had any issues. A simple remap is well within manufacturers tolerance and even a stage 2 isn't going to cause catastrophic failure. My mate has a mk2 leon cupra running 360bhp over the last 70k miles. Yes the clutch has been replaced but no issues with the engine but by your reckoning he should have rebuilt and strengthened the complete engine. I could understand you bad mouthing tuning if you have had issues personally from remapping etc but I don't think this is the case. Oh by the way....I am a qualified automotive engineer.

I'm not looking for an argument either.

Good. :sun:

Brother is running a K04 GTI with 220kw at the wheels with no issues at all. Stock internals and transmission. He's not the only one too. A chipped RS will easily handle the power. Bring it on i say. 

been running my 2.0 TSI at Shark stage 2 for over 2 years now, cant say Ive had any issues (touch wood)

I have just got rid of (almost gave away) an Alfa 156 Sportwagon 2.4 JTDM 20v. It was remapped from 175bhp to 215bhp, with a big increase in torque that I can't now remember the figures for. I had it for 3 years and must have replaced 4 drive shafts over that time, which I assume just could not manage the torque. Also cracked the turbo housing, which may or may not have been attributable to the remap.

That's what happens when you play Russian Roulette - sometimes you win, sometimes you don't.

Differences between manufacturers also play a part ie how much development and tolerance they tend to build in. The three most unreliable cars here at work are an Alfa, as above, and two Peugeots - they arent exaclty old and are always suffering failures. I never have an issue with my modded cars. Its not as black and white as 'Russian roulette - sometimes you win, sometimes you dont' 

To a certain extent I'd agree, - It's a real shame about Alfas, used to be great cars, now they are just badge engineered FIATS. Peugeots - well I'd never buy any French car!!

Back on topic, the milltek system should be appearing July time. Time for some noise

Any news regarding stage 2 software?

Still no test car I'm afraid, so we have nothing more to report. Our development was done on a Golf GTI which is technically the same, but if you want to see an actual Octavia then we can't help at the moment I'm afraid.

Rumour from skoda hq in Milton Keynes is theirs an Octavia Vrs 280bhp version coming soon with possibly 4 wheel drive. The training guy I was talking to had just come back from the skoda factory in czech republic.

bump!
