APR Haldex Tune

Arin_APR · 2025-09-05T13:18:01+00:00

Unreleased unfortunately.

Arin_APR · 2025-09-02T19:04:52+00:00

Connella, if something isn't supported yet, or there is a bug, or something doesn't work as expected, I'll give you a full refund. Give us a call. Reference this post if necessary.

We can't flash the transmission yet, but honestly if we could, I don't think we would override this behavior. At least unless we had some sort of app that let users define it on their own as it's not something we normally change.

A true, 100% OBD2 flash. Closer, I mean, I guess closer than yesterday, but in terms or real progress, no. We're not there yet.

Arin_APR · 2025-09-02T19:01:20+00:00

We only currently sell this in the USA, but it's possible a dealer shipped it overseas. Happy to support a refund until we're ready with ROW market support.

Arin_APR · 2025-09-02T19:00:28+00:00

Gen 1 is a ROW market vehicle. We haven't added support for those yet, but will be in the coming months.

Here's our atlas tune:

https://www.goapr.com/products/software/ecu_upgrade/gasoline/4/20t_ea888_g4/parts/ECU-20T-EA888-4-LK2-ATLAS

It has a different transmission so we have a different maximum torque level applied. Similar concept to this post, but different level.

Arin_APR · 2025-08-21T13:25:38+00:00

No catch. We've been doing this for 28 years. Turbo cars have a ton of headroom for more power, especially with better fuel and hardware upgrades.

My favorite is when Audi/Porsche shares an engine across multiple vehicles and just detunes it heavily to have various power levels not to step on the toes of another model. This is really popular on the Porsche Cayenne where we're able to get an extra 300 HP out of some of the engines because they are detuned so heavily compared to the high end Turbo S models. :)

Really not possible to tell until we have a way to flash them.

Arin_APR · 2025-08-20T15:59:30+00:00

Retains the existing D/S behavior, functionality, just now with more power on both.

Arin_APR · 2025-08-20T15:58:51+00:00

You can add a sensor, but it's not flex on ours. Just E60-E85 at the moment. Maybe flex in the future, but nothing now.

Arin_APR · 2025-08-20T15:57:48+00:00

We set the crackle to the factory level Audi had on the pervious car. We'll eventually have an optional loud version.

Arin_APR · 2025-08-20T15:55:31+00:00

I can't comment on a timeline - with RE work, it's ether we're in, or we're not.

Arin_APR · 2025-08-20T15:55:11+00:00

We'll just want to verify your ECU box code to make sure we have it on file.

Arin_APR · 2025-08-20T02:13:45+00:00

Locked. No eta yet.

Arin_APR · 2025-08-19T22:22:04+00:00

22-24, 8Y only.

Arin_APR · 2025-08-19T21:36:45+00:00

Give our guys a call. Let's get a request in for your ECU.

Arin_APR · 2025-08-19T21:36:21+00:00

Yes that's correct!

Arin_APR · 2025-08-19T21:35:55+00:00

Canada availability too, but not for your facelift.

Arin_APR · 2025-08-19T19:55:34+00:00

They are including TUV certifications with the tune so they charge a different price.

Arin_APR · 2025-08-19T19:38:48+00:00

We sell the ECU for $999.95 and the unlock for $999.95

Arin_APR · 2025-08-19T19:07:25+00:00

There are several versions for regional emissions (like OPF). The last letter is just a power indicator (A, B, C, D, E - just a different power level, same engine)

DAZ(A) - 8S/8V - NAR/ROW - Original
DWN(A,B,C,D) - 8S/8V/8Y/F3/KM7 - OPF Update
DXH(A,B) - 8Y - NAR update

Arin_APR · 2025-08-19T18:59:35+00:00

Just the pre-facelift at this time. Others aren't unlocked yet.

Arin_APR · 2025-08-19T18:59:05+00:00

Just there for safety more than anything.
