Hello all,

I'm looking for some feedback from those of you who have their EA888.4 ECU and DQ381 TCU tuned. Ideally, from those with the 245 version, although I'll still happily hear out those with similar EA888.3 245/280 models.

I'm currently in between two possible solutions: a comprehensive RacingLine OEM+ Stage 1 ECU/TCU tune, versus a combinations of Revo Stage 1 (ECU) and TVS Stage 2+ (TCU). In both scenarios, I'll be aiming for a 95RON, low-torque file, since I'm not only limited by the dealers around me, but also by fuel quality and grip (FWD vRS). I'm only looking for improved daily-drivability and some additional power under the curve.

If you have experience with either setups, please let me know what your experience, what you preferred and why, and any other information you might relevant.

Note: I understand the DQ381.2 TCU has only recently been cracked. As of today, both RacingLine and TVS offer the same flashing method via the TCU connector, but the tune itself has been around for a while for the '19-'21 cars. However, if you think there's something worth bringing up in regards to this, please feel free to.

Thank you all!

EA888.4 280 here. I went Racingline for TCU as I bought it along with Stage 1 ECU and I bought the dongle (PDM, not PCM) to self-remap which means as I progress with the tuning the additional maps are free.

However, the TCU remap does involve a bit of mucking around as the shift points are right at inconvenient points for town driving and there aren't a bunch of features that TVS seem to include. If I was to do it all again, I'd go for TVS TCU Stage 2+. I haven't found anyone have a rubbish experience with their product although they were awful at getting back to me when I enquired direct - possibly some of that a language barrier.

Best to just find a decent place that is a TVS dealer in Warsaw and let them do it all. TVS do an ECU so you could get a combo but I don't know how good that is.

Thank you very much for sharing your experience, that’s a really important point that wouldn’t have crossed my mind.

I’ve been struggling to find anyone’s review of their TCU tune, but plenty from those with the TVS tune - all of which seem to be great, as you mentioned.

Since the majority of my driving is in the city, that’s probably enough to push me in the other direction.

Based on your feedback alone, seems like that’ll be my go-to, although I’m no longer in Europe, hence a lack of tuning options.

I toyed with the idea of a TVS Stage 1/1+ ECU tune as well, but it also lacks reviews, and it’s more of a custom tune rather than OTS like the others.

EA888.3 2020 vRS here.

I would go for a TVS TCU tune and then, personally, a custom tune for the ECU. Offerings from APR, Racingline, Revo, etc are very good, but they just can't match the work of a tune that is developed and customised for your specific engine. I'm not too sure who is available in Eygpt, so it may be that the safest bet is to use one of the former 'flash maps'. Of the two, I would probably go for Racingline - they tend to be a bit more conservative than Revo (from what I know, anyway).

Something that I am keeping an eye on... https://roadrageperformance.co.uk/vag-vaq-fwd-tuning/

Lucky you know someone with the cable already...

My guess is that the more generic TCU tunes alter the shift points and increase the clutch pressure to cope with increased torque. TVS look like they go into more depth with it all.

Any named brands will be generic ECU flash maps. How good they are depends on the experience of the coder (Racingline OEM+ used to be Shark Performance which had a very good reputation and has the main guy still there) and also how close to their generic tuning the engine is.

As said, nothing beats a custom tune, but the pitfalls of it are:

1. Probably more expensive as time taken to do it and tweak it

2. Any time you change parts, the tune is compromised because it was setup for the existing setup.

Having said that, only as compromised as a flash tune but then you might as well just get it flashed and be done with it. I think I'd only ever get a custom tune when I know I'm not going to do anything else to the engine.

I do? I didn’t think their car ran RoadRage software though…

TVS are a little more considered with their clamping pressures - any idiot can stick 20 bar onto the clutch pack and see how long they take to disintegrate.

I agree with the above, however I would also add that it depends how you drive it. If you’ve got some random Superb with a BONOSS wheel retention method, and only floor it in a straight line once a week, then you’ll be absolutely fine with a flash map. If you’re sending the engine to the moon on a daily basis then I would try to get the best you can get, with a custom tune.

For Stage 1, really, it’s not massively important. It’s only when you start getting to Stage 2 and above that the tune really matters. You could go for Revo, Racingline, APR, Cobb, IE or anything and be absolutely fine, I think. Frankly, if I was sending my car I’d want to invest in a DSG cooler, larger intercooler and some other bits, starting with a RARB and ending with stiffer springs.

True, and there's a handful of good tuners out here, but since most of their work tends to be motorsport builds, I'd rather not resort to them. I'm more interested in a tune that focuses on partial throttle drivability rather than full throttle and maximizing power output, and sometimes an OTS tune is exactly that.

TVS truly is unbeatable when it comes to DSG tunes. I was really hoping to find some good reviews of the RacingLine TCU tune that would convince me over, since it's all marketed so well and looks great on paper, but your feedback put things into perspective.

Now it's down to whether I get a RacingLine PDM and flash the ECU myself, or drive over to the Revo/TVS dealer. Might just come down to the cost of it all!

There’ll likely be people who offer multiple providers. See if you can find a RacingLine ECU tune and TVS TCU tune?
