Met the guys from Wow Tuning at the recent Nec caravan show, am thinking of remapping my 110 hp td to 140 hp , as they said my 110 td is a perfect engine to remap as it is the 140hp engine detuned. Any one used these guys? as I have no experience of remapping is there any thing I should be aware of with regard to warranty, DPF problems or any other associated issues. sorry for my ignorance of this subject as much as much as would like 140hp, feel nervous about going ahead without some second opinions. Thanks

Check with your insurers first - and use a reputable remapper.

Look up Shark Performance on here for good advice.

110 could go as high as 180bhp so 140 is no problem big problem is mo one has yet cracked the ecu on the new yeti 110

So if 110 can go to 180, what could a 140 go to, or Sven a 170?

Various companies are offing to remap a golf CR140, but not many the Skoda 140. Is there any difference?

What are the advantages of a remap over a black box that plugs in? I had a DPT box on my octavia for a while, but that was a PD engine. I understand the CR engine works much better with the black box than the PD one. (both 140's). Does require a different box.

Also, what is the difference between the 3 engines. Is it just software or is there some other modifications to them?

That question has yet to be fuly answered, but is very interesting.

Known diffeenes are that the 11 uses a 5 speed gearbox and the 140 and 170 share the same 6 speed and final drive ratio. . The 170 has significantly larger brakes and a different rear muffler.

One would assume that the three engines have differet injectors and different turbo sizes, but I have found no real data. There may also be diffeent auxiliaries, like the intercooler and mass sensing unit. The camshaft may also have a different grind, but again no data.

In the "good old days" before the introduction of chips, to tune up an engine, a list of bits were changed:-

Different head with opened up valve bores and higher compression ratio.

High lift cams probably with different timing.

Improved inlet and exhaust.

Possibly a different crank with a greater throw.

etc. etc.

How do you expect a chip to radically upgrade an engine unless it was already at the top performance and the existing chip detuned it to a lower output. The mechanics have all to be in place before the electronics will give an improvement.

Are we to understand that all the TDI Yetis have a 170 engine and all we need to do is to put a new chip in?

That is, of course, the $64,000 question.

All the 2.0 TDI engines have the same displacement, so same crank throw, but that is all we really know. Main bearings are probably the same size, as differences would require a different casting - not likely for economic reasons. The higher HP engines certainly can have differnt "drop-in" parts, like forged crankshafts, diferent con-rods and pistons and different valve trains, as these can be easy production upgrades to the basic engine.

How far they will go with that same base engine is also a good question. I understand that the new Passat due later this year will be available with a 205 HP version of the 2.0 TDI with two turbo's. Somewhere between the 110 HP and the 205, there must be some upgraded components to handle the additional loads - but where is ther break?

I am really amazed at the reserve power in the 170 at speed. at 180 kph (110 mph) you would expect it to be a bit sluggish to accelerate further, bo no, it just wants to continue higher.

Even in the brochure the 110 is shown as having two different torque outputs depending on whether its 2 or 4 wheel drive.

My guess is that there is very little between all 3 engines. The old 170 was different to the PD 140, different type of injectors, DPF and such, but from what I've seen published so far, these units share a lot more commonality. Someone must have the definitive lowdown on them somewhere.

Figures for Octavia but same 170CR engine

Whoosh!

Interesting thoughts here - I must admit to having an interest in this with a 110 due for delivery this next week and slight regrets about not ordering the 140 motor.

In a previous life I was in manufacturing engineering and was playing about with CNC (Computer controlled) Machines and was involved in buying a Japanese 3 axis milling machine with pretty basic specification .On delivery, talking to the Installation Technician , he told me (and demonstrated) that most of the electronically controlled optional features that we hadn't paid for were in fact installed in our machine but efectively locked by the factory.

He offered to unlock all these parameters , at what would have been a tremendous cost saving to us , but then revealed that as the factory had the original build spec then any warranty claims could/would be invalidated.On this basis we left well alone.

On a similar vein, reading other threads circulating on the forum - standard fitment of Daytime Running Lights on Yetis - unlockable by manipulating the key and indicator stalk for free or ordered from the factory at cost , I wonder just how much "free kit" is actually already on the car and just needs a series of codes to unlock? Does this apply to the power conundrum , does the chip just detune the engine down to 110bhp?

On a different note whilst still in engineering we were "given" a Skoda CNC lathe - unfortunately it was a shonky lump of metal only fit for use as a boat anchor - how the build standards have improved!

If anyone does take the plunge in re mapping to 140 I'd be very interested

Coincidentally, my TDi CR140 Scout is being remapped as I write this, with an MTM Stage 1 remap (with no impact on full Skoda NZ new car warranty) . It's possibly the first CR-engined Skoda in NZ to get this particular treatment, so I'll be interested to see how it goes. I've entrusted the task to an experienced VAG engineer with a reassuringly eastern European name of Zsolt (his details here). It's a reasonably convoluted process involving the removal of the encrypted ECU from the car (I don't think it's yet possible with the latest generation CR engines to remap with the ECU in situ).

Post remap, I should be looking at 125kW and 360Nm :p .

Whoosh!

I have a little problem with the link:

How trustworthy is it when the torque figures are so obviously incorrect?

I've no reason to suspect Revo's figures; I've had their remaps on previous Golf GTI's - both of which were Rolling Roaded on Dyno Dynamics machines before/after remapping and figures confirmed.

I'll pass on your scepticism to Revo about the torque figure when I next speak to them - but they are a very well establised company, specialising in VAG software. I doubt they'd make a mistake with their figures?

And no - no need to remove ECU's and open up - remapping done through the OBD port!

And finally - please tell your insurers before you think of doing this.... it's a no-brainer not to!

I work for lots of insurance companies, and they will wriggle out of covering you if they discover you have modified the car without telling them. So if you then have an accident you will end up personally responsible for all costs.

As an aside, one of the most common reasons insurance companies wriggle out is driving somebody else's car, with permission, thinking that they are covered under driving other cars cover. NEVER let anybody drive your car unless you have seen their policy confirming that they have cover, because YOU will be responsible personally.

Maybe I should have been more specific. The graph looks OK, but the table that first shows up at least does not use Newton/Meters. Since there are no units shown, it could be something else Foot/pounds or??

Surely the main problem with a remap other than insurance, is that other components in the drive train might not cope with the additional output, shafts, brakes , etc. would also need speccing up.

I would think with the modest amounts of extra power, most components would be fine, though longevity must reduce a little. Clutches may be a problem if you have an obscene amount of additional torque coming in as one lump, but never had any issues with remaps overloading components on cars I've had done.

From a link on the chipping 1.2/1,4 tsi I found this

140bhp Tiguan

ABT will go up to 140 with I think a software update, or with an ABT turbo, up to 200bhp.

There you go bahnstomer, that'll get close to your old vRS
