Does anyone here know anything about the tuneability of the new WLTP Cupra?
It seems as if it now only have 4 injectors (DI) compared to the 2014-2018 Cupra which has 8 (4 DI and 4 "regular" styled injectors).

It would be interesting to see if it still would be possible to acheive up to 400hp on stage 2 and even up to 500hp with just upgraded HPFP, turbo, exhaust and IC.

When I spoke with Revo they said that the WLTP Stuff is a way off yet as they have lots of other projects to complete first.

Also have a read of

@CupraSwede did say he was going in for a map and put up some figs here https://forums.seatcupra.net/index.php?threads/my-400hp-sleeper-wilderbeast.451525/

"Way off" as in nothing that will be ready in a long time?

I've e-mailed with Celtic tuning and they state they have a remap ready.

Yes i've read and seend the numbers posted by "CupraSwede", however 400hp with a larger turbo doesnt sound very promising at all.
The "old" Cupra could acheive up to 470-480 with the STM400 that he most likely fitted..
I also asked about this in his thread, why they stopped at 400hp.
It could be as simple as he is running stock exhaust, no ic, no HPFP upgrade etc.
It would be interesting to know the limitations of the new engine and what the limiting factor will be..

I really hope it will be as tunable as the previous one..

Yes Long Time but that is Revo they tune and test for Longevity (in my opinion).

I did see a post from @AlexOS I think (may be wrong) that said APR were also looking at it but not in a short time frame and they had had a go on some cars and did not get good results but cant find the thread now.

I also know that a lot of the newer cars the ECU is locked out at this stage so again the turning companies are working on hacking back into the box.

I didn’t think the old car had 8 injectors, just 4 in a different place?

Older cars had injectors in the manifold, while newer cars use DI (https://en.wikipedia.org/wiki/Gasoline_direct_injection).
The first revisions of DI in VAG engines had huge problems with carbon buildup and it was believed that VAG brought back the regular styled 4 injectors in the manifold to help wash the carbon buildup back.
So the EA888.3 has 4 DI and 4 old fashioned injectors running of the LPFP.

Actually i dont think there is any cars around 2017-2018 that arent DI. Its just that the EA888.3 engine uses both types of injectors previous to the WLTP-certified engines :)

Stage 1 is 400hp at Stertman, before OPF and after so nothing new. To get more you need to change exhaust, IC etc

Also what do you mean by "before OPF and after so nothing new"?

They mayor diffrence with the WLTP and pre WLTP Cupra seems to be the OPF/GPF ofc and also the change in fuelling, 4 injectors vs 8 injectors.

I mean that stage1 is still the same hp and torque with/without opf and injectors. And yes stage1 is just below 50k sek.

According to Stertman the 8 vs 4 spreaders will affect the tuning when you go higher then stage 1. The WLTP does affect the tune in a negative way.

So what power levels will be achievable with upgraded hpfp?
The interesting thing is that Stage 1 on a Cupra in the UK or any other part of the world isnt really the same as Stertman's stg 1.
So it's not really easy to guess what they mean...

It would be interesting to know if the 2019 EA888.3 even use the same DI-injectors and HPFP as the previous ones or bigger ones..

Suspect the generic Stage 1 tunes of a WLTP engine will be ~ 350hp based on the ABT Module on the Cupra Ateca engine. Yet to see if the Cupra R ST actually gets its claimed 370.

Custom tunes though, as opposed to full R&D developed over a longer time tunes to improve longevity of the engine. Suspect they're getting closer to 390-400 on not WLTP car.
No, thats more his stage 2 figures. Similar 360/370 for stage 1 on earlier models too. Rick at unicorn is well known for the R&D he puts in. Has a huge following on the golf r forum

Here is the picture of the graph from the dyno. As KernelOkey said. Stage 1 at Stertman is: a new turbo and a tune of the engine and DSG.
Quote from their page on F-B "Brand new Seat Leon Cupra ST 300 OPF 4x4 with our popular STM400 hybrid turbo and STM Stage 1 calibration, this is probably the first OPF car in Sweden that has a hybrid turbo and tune."

Hi Guys, I have just contacted DMS Automotive to get a quote and some figures to tune my 2019 Cupra.
They said they can get over 378bhp and over 373 lb.ft. out of it!! Food for thought whether the front wheels will cope with all that extra power and torque?!
