I would be interested to hear from the many knowledgeable folk on this forum about the pros and cons of chipping the Yeti. As I understand it, chipping my diesel 170 BHP 4x4 Yeti could take the HP to about 210 HP; more torque (about 420 Nm) and apparently better fuel consumption. The chip apparently works by increasing the fuel to air ratio; changing the timing and increasing the maximum RPM. If this is the case, what are the downsides – presumably shorter engine; turbo; GRV; DPF; etc. life and reduced reliability? But if these downsides are minimal, why does Skoda not make a more powerful Yeti? Is it mainly because the big manufacturers are driven by legislation to make vehicles with lower fuel consumption and cleaner exhaust gases; or because the downsides are severe? I also cannot understand how increasing the fuel to air ration results in lower consumption? I would be especially interested to hear from those who have chipped their Yetis (not sure of spelling?) about their experiences of reliability; shorter engine life; fuel consumption; etc. Thanks.

The reasons that Skoda (or any other manufacturer) doesn't tune a car to its maximum is many and varied, but in the main, it's to ensure the best balance between longevity, performance and economy across the globe. So the car will run on crap fuel in sub-Saharan Africa or in an Alaskan winter. Dial down that compromise, accept the extra strain on clutch/gearbox, accept that more power really needs more brakes and better handling to be as safe and away you go.

To sell a 200+ BHP Yeti, Skoda would need to make the necessary technical changes to keep the package safe and reliable and there isn't a market for such a car as the average Yeti owner isn't after a crossover hot hatch.

I don't know how old your car is but disadvantages include possibly making your warranty 'toast', increased insurance costs (or the risk of being uninsured in the event of an accident), over stressing other components.

Advantage - the car will go quicker.

Hi,

If you need any help with insurance for a chipped vehicle then please feel free to drop me a line.

I've sampled CR170 4x4 Yetis in standard mode, with a CRD-T 'box' and with Shark STS remap.

 

Over the standard map, the tuning box gave a shed load of extra performance in a pretty harsh way and screwed the Maxidot MPG figures. Fuel consumption though brimming was worse than standard.

 

Shark STS was very subtle increase because it is such a well sorted remap but it really does work incredibly well (standard map seems asthmatic afterwards) and is noticeably smoother when cold. Fuel consumption dropped approximately 1% despite utilising the extra power. Maxidot MPG was about 2% more accurate. Fuel used was Shell Nitro Diesel.

 

Okay, potentially there is more 'stress' though the drive train but you don't have to use all of the power/torque all of the time.

My Yeti is the fourth VAG TDI car that I've had remapped; I've covered high miles in all of them without any issues at all.

I have the same map on the Yeti as Aerofurb; lovely and smooth - no masty torque spikes low down the rev range that I've had on remaps on previous cars (which can make the car *feel* fast but is not good for your drivetrain, DMF, clutch etc).

I also use Shark's STS handheld device that allows me to switch between standard map and remap at will - when it's back in standard it really does feel asthmatic like Aerofurb says, runs out of puff much earlier in the rev range whereas with the remap, it keeps on pulling which is great when overtaking.

If you drive in the same manner as before, you may see a slight MPG improvement. Obviously you have more scope to reduce MPG too, depending on how much you enjoy the increased power. The "improved MPG" argument is good to trot out when trying to convince the other half it's a good idea but in reality don't expect much change

The advantage of the 170 Yeti is that you already have larger brakes than the rest of the range.

If you're half considering it - I'd say just do it. Declare it to your insurers, it won't affect your premium too much but will put a smile on your face when you want to use it
