When you get your map fitted ask for the linear throttle mod. Makes driving the car more like a wired throttle so you have 1:1 input, as opposed to incremental. The car is so much more driveable and the engine feels more responsive. I did mine via obdeleven.

do you know if this is applicable to mk2's ?

I'll be interested to hear whether this causes any issues with the clutch over time[...]

Also, with standard hardware will this not generate a higher than normal intake temp due to the std intercooler and the increased pressure?

 

Not personally had any issues with heat, and still have standard inter-cooler fitted. Since the coolant temp seems to be glued in between 95-100 deg.C on the dash, I would think it would get higher under longer stress-cases (e.g. on track, as above, or long-term spirited driving), but it's not a Stage 2+ map.

 

As for the clutch, I've noticed occasional minor slippage in 4th or 5th when accelerating from an inappropriately lower RPM on the motorway (as the added torque overcomes the plate), but this is easily dealt with by dropping another cog. 

 

As with basically all things, when you start tuning / calibrating the car to more specific use cases, it's therefore worthwhile treating it with more attention to detail. For example, more regular checks and shorter oil change intervals, better quality fuel (99 ron), more controlled throttle inputs and decent gear changes, and generally having good mechanical sympathy.

 

Mine's been mapped for 18 months and had zero issues, other than a turbo sticky turbo actuator about a month post-map (although chalked down to a regular EA888 issue) and the EMS light showing for a few months before I took it to RL MK HQ to get fixed.

That's what I like to hear.

The mk2 can be  changed to linear 👍

Thought I would show the dyno graph from my remap

can it be coded via ob eleven/VCDS or does it have to be mapped?

Regarding temps, I don't mean that the engine the water or oil temps will get higher, I mean the air inlet temps for short periods.

 

Running higher pressures will increase the inlet temps due to the compression, and the turbo spinning faster so the inlet air would increase in temp if not cooked sufficiently by the I/C.

Ultimately this could cause detonation if it got too high.

 

I presume (please correct me if I'm wrong) but the likes of a golfR will get 300bhp with lower intake pressures due to being able to get the same flow with a larger turbo and less restrictions.

 

Obviously the turbo heat soak will be time dependant, the compression heat is instant.

 

I have no idea what the danger zone is and genuinely wonder how close remaps get to it without hardware changes and wonder what the air inlet temps are in a remapped car in comparison to a stock one.

 

This is mainly my engineering head being interested tbh.

The Golf R has a bigger more effcient intercooler than say the Golf GTi or Octavia Vrs 220/230/245 so it can cope with higher boost and higher temps. The Superb 272/280 also get the Golf's bigger turbo and the larger intercooler and manage just fine with a stage 1 remap (mine is running 360bhp and 514nm). What prevents pinking or fuel detonation is 99 octane fuel such as Tesco Momentum or Shell V-Power Nitro+ and any decent tuner will insist you use either of these fuels in the UK to maximise the gains but also to prevent damage to your engine. My Octavia Vrs245 did 29,000 miles with no issues on V-Power coping with 336bhp and 517nm at stage 2.

My tuner said the same thing regarding using higher octane fuel. He stated some drivers have had engine problems when using lower grade fuel. I used to use 95 octane for 3 tank fills and better fuel for the 4th. It's the best fuel all the way now, even if it does cost me with the amount of miles I usually do when working. Must admit mind, when I had my last VRS TSI Octavia mapped, it did for the majority of fills, get the 95 octane. Never had a problem in the last 40-50k miles that it had the map on.  It did however only go from 200bhp to 250bhp. Maybe I was just lucky!

Trying to get rid of my map graph that now appears on every post I make. Maybe someone can get rid of it for me.

For example Steve Sutcliffe well known motor mag journo was running a 395bhp (400PS) Audi RS3 for 6 months and couldn't find a garage with 99 octane fuel so put some regular 95 octane in it and the ECU was clever enough to realise and restricted engine revs to a maximum 4,000rpm to protect the engine.

It does make me wonder though, that if Skoda think to get 270bhp in a superb then it warrants having that upgraded intercooler and turbo, how running the smaller stuff at 320bhp is not without compromise.

After all, car manufacturers don't spend money when they don't have to.

That compromise may be risk, that they're not willing to take, I don't know.

Don't forget VW Group buy in bulk so the larger IS38 TURBO goes into the Superb 272/280, Golf R hatch and estate, Audi S3 hatch and convertible (not to be replaced sadly), SEAT Cupra Ateca and T-Roc R to name a few and the new Arteon will have 316bhp (320PS) and similar hardware so mass purchasing keeps costs down when all these cars use the same brakes and 7 speed DSG as well.Economy of scale and the MQB platform go hand in hand.

It can be coded by vcds or obdeleven.
