It will pass NY, MA and CA inspection no problem

And sport mode has the flaps open 100% as a standard! Comes on all the tunes.

We offer a stock style throttle or an aggressive one. You can pick it when you select your tune on the tuning suite. And you are free to flash between tunes anytime

Are you sure on that? California just instituted a new law regarding ECU's.

My car was a cali car that passed w/ the Jackal tune and catless DPs, but that was early 2023

**DWRS4** · 04-29-2023 09:11 AM

I still cannot decide whether to just do a cc (and maybe put some loctite around the flap screws) or do the cc + deflap + jackal tune. My concern is that if you look at the RS4 dyno graph on the jackal website, you can see that torque peaks at around 3800 RPMs, on the stock tune the peak occurs at much higher RPMs l (around 6000 from what I’ve seen on other dyno graphs) so you have to rev out the engine. I don’t doubt that the tune makes the car faster, but for those who have it, does it change the feel of the car, with more torque down low?

On top of screws backing out, flaps can break, and with age when the screw are tighten with loc tite, could cause stress cracking through flap cycling, and a piece of flap breaks off. I don't know the real stats on this stuff, but even the .5% chance was enough for me to remove them all. We do have a replacement motor issue with these cars so not worth the risk for anyone to keep them in my opinion

Someone else should answer to your torque peak questions, interested to know too...

Did you replace your IM flap arms with 034 billet aluminum arms to avoid any potential CEL with the deflap and future arm failure? Or did you keep the plastic ones? Thanks.

I did not replace with the 034 billet arms. I was able to borrow the 034 punch tool from a local owner who did install the arms. That car had 272,000KM at the time and had been de-flapped without a tune and running fine like that for about 100,000 KM (AND had JHM intake spacers). I don't have the spacers, and my car was fine without a tune, until these codes popped up a while later. Because they were a while later, I still don't think have anything to do with de-flap.

When I did my de flap, upon reinstall, I only had my cat delete codes, which were there before. In the past year at some point, I got a code that seems to pertain to the flap sensors. My car is currently apart, but the defective one is the passenger side (IIRC my codes) for me, and can be changed in service position without IM removal. The flap sensor at the back, driver side requires manifold off. I do remember reading posts about those arms breaking for some, but my guess is that people rough tumble with them on delicate IM removal and positioning on a work bench and break them like that. For the function they have, they seem strong and well built enough. Plus, IIRC they fit into some little plastic ball and sockets joints so the actual arm I don't think would cause an issue. << This is still just speculation though. One of my arms did have some play, you will probably get the work done on your car before I make a IM video part 2, but I'll link my YouTube and you can follow to see what happens with my car. My codes could be for the flap sensor or a cracked vacuum line under the IM. I doubt it's the slightly loose arm mechanism, but not ruling that out.

Edit: I can't recall if that person had a JHM tune with the install of intake spacers. He told me the info that it would run fine with de flap and no tune was what I based my attempt on. Reliable source as he worked as a pro euro car mechanic. Another local rs4 mechanic that sees a few of these also told me it would run fine with no tune and de flap, and that the car would just have some hesitation on cold starts sometimes for a very short duration

The Kalifornia Law went into effect on July 19th 2021 so the previous owner probably got in under the wire.

Here's a good reminder to anyone running a tuned car out in California: As of today, July 19, the state's notoriously strict smog testing will automatically fail any car when it detects modified software onboard, aka, a tuned ECU. Drivers can't register a car in the state unless it's passed a smog check.Jul 19, 2021

I want to add that I just flashed the latest file today and it really cleaned up first and second gear throttle response and feels fantastic!!

Could you share whether you picked the “aggressive” throttle map or the “close to stock” throttle map?

**WinterRunner** · 05-03-2023 04:22 PM

I picked the not-stock throttle map, 93, no flaps.

That is a deflapped car, with an unknown last carbon clean

Might want to update that with a clean running RS4.

I'm super happy with the tune. Car feels much more eager and responsive!

**longlivenacars** · 05-07-2023 03:15 PM

Off topic on this thread, but was discussed here, so posting here. Edit to my 4-29-2023 post. Looked at my car today, and it isn't ball and socket, it's more of a pin (looks like a dowel pin, don't know technical term for it) that is held in by what seems to be integrated, plastic retainer clip, onto a circular ended pin. Some wobble in mechanism on mine but will see in future if it is an issue. The play on mine could also be at the other end of the arm which is not visible in the pic, but been a long time since I've seen under manifold. Note that access for this pic was done on an rs4 that is currently in service position

So the stock throttle is more or less aggressive than the aggressive one? I currently have the "aggressive" one on and it seems to have smoothed out delivery, not made it harder to modulate. Will the stock setting be even smoother? I always thought the touchiness was due to the OEM self adjusting pressure plate.

Yep! The “stock throttle” map is just that, stock throttle parameters. Sport will be a little touchier like factory. Since that’s all it does. Sport also keeps the exhaust flaps open 100% of the time.

The normal files that don’t say stock throttle are a more aggressive, enthusiast style map

Both have the same overall power

Got in for a last second flash today and really enjoyed it so far!

Power feels so good in the low end and its really consistent in the mid to upper range, that new redline is fun too. Gonna try out aggressive throttle map and possibly E30 tune.

Cheers!

Whats the new redline?

Wanted to drop a line to say thank you to Jackal for working with my shop recently to really improve the drivability of my RS4 cab.....the revisions have made the car a daily driver for my wife and now we never hesitate to drive it anywhere....I really appreciate a supplier that supports the product so well after the sale. I'm a fan and will look to add more Jackal to all my cars.

**DWRS4** · 07-12-2023 02:29 PM

I had my car deflapped and Jackal tuned a couple of months ago. Love it so far. It’s smooth and definitely feels like more power (I picked the stock throttle mapping and did a carbon clean at the same time so it’s not just the tune). Only downside is the SAI is now more aggressive during cold start ups: the car revs to about 2000rpms and feels just slightly rough—only for the first minute though and then it’s super smooth when the SAI process is complete or I start driving. I have only driven it a handful of times but so far so good.

Mine stumbles and misfires during SAI. Would be great to have SAI disabled with emissions readiness

Are you saying it has issues WITH the tune?

Yes both with and without, ever since my flaps were taken out

**WinterRunner** · 07-14-2023 08:54 AM

My starts seem a little weird, but no mis-steps so to speak, just not a "dope" cold start like my R8 and even my 1.8T b5 have. When moving it's flawless and I find the drivability is quite good.

**Matt@Jackal** · 07-15-2023 01:49 PM

Just shoot us an email, maybe we can have you log the cold start for us and see what’s going on

Flashed the jackal tune today. They were really great to work with and made the process easy even with some laptop issues. Protip dont use a windows 7 laptop with their software.

The stock throttle map is nice for drivability in 1st gear compared to my previous tune. I havent had a chance to rip through a few gears yet, but will report back once I do.

Does anyone use the pop&bang option on their RS4? Would love to hear what thats like.

**komseh** · 09-06-2023 07:48 PM

Butt dyno says the car definitely netted some torques from the jackal tune :)

Is it normal to have slight fluctuations in the rpms at idle, like 30-40 or so? just moves around 800 a little, nothing startling.
