Stage 1 Tune for 2018 RS245

Yeah, that's what I thought.

I know the Skoda Australia Facebook page likes to pump up expensive replacements, but I appreciate the advice on here a bit more.

In my experience, with a front wheel drive you will spin the wheels before slipping the clutch in the vast majority of cases. Whereas in an all wheel drive car, you are much more likely to get clutch slip.

When I had my modified Golf R, I got clutch slip only once or twice and it was when in a higher gear at low revs where it was in its torque band (eg in 5th gear at 80kph and you try to accellerate to get through an orange traffic light or overtake someone). If you knock it back a gear then you will be much less likely to get clutch slip.

I never experienced clutch slip in either of my modified GTI's.

Super interesting, thanks for the explanation. 👍

This new tune comparison video is interesting. Note lots of rural USA only have 91 octane fuel which is equivalent to our 95 RON fuel. This test is done using the lower octane version of the tunes and using the low torque versions of each companies tune.

This same guy is soon going to do the same test with the higher octane version of the tunes (95RON which is equivalent to our 98 RON premium unleaded fuel) so it will be interesting to see the difference in power between the different fuel, where they can push timing and boost more with the better quality fuel.

Thanks for the link. I will have to look up the reasoning between the octane rating difference too.

Relevant info under "measurement standards":

That's interesting. Would be keen to know exactly what engines they do the testing with.

Think of it in the same way as metric vs imperial. Or saying 'tires' instead of 'tyres'. Or saying 'gas' instead of 'fuel' or 'petrol'. Or saying 'a.lu.minum' instead of 'aluminium'. USA seems to like 'being different' to the rest of the world for no relevant reason.

USA 91 octane = Australian 95 RON
USA 93 octane = Australian 98 RON (BP Ultimate / Shell V Power etc)

They use an engine specific to the task - nothing that is fitted to a commercially available vehicle. Testing occurs at relatively low RPM and the ignition timing can easily be varied. At the end of the day, the type of engine is largely irrelevant - it's about controlled conditions and being able to compare the knock resistance of any given fuel against a control.

I would be keen to know if anyone on here has the 034 from VAG, as it is only $900 including dongle.

I know you typically get what you pay for in this world, but the next option I am looking at is almost 50% more expensive.

i paid that much for a Stg 1 APR tune.

$850 for the APR Stage 1 ECU hi-torque tune.
add another $800 for an APR TCU tune.

on the dyno it made, at the wheels, 223 kw and 530 Nm.

i have a FWD Superb with the 162TSi (220) engine, DQ250 6-spd DSG.

That's fantastic. Thanks for the heads up. Also, that Superb looks......superb 😆💀

[dArK5HaD0w]

thank u.
i'm due for another dyno run as i've recently had an Integrated Engineering FSD intercooler installed.
in theory, that should make that power & torque curve last longer before dropping off the cliff!!

i was planning to get an IE downpipe too, but APR has ruined my Stage 2 plans because their Stg 2 files throw CEL errors.
sux.
