APR TCU tune...worth it?

Going to get their ECU stage 1 upgrade and wondering if I should also do the TCU tune, what do most people here do? Car will see the road track. Spend the money or not worth it until stage 2 or higher? Thanks

Totally worth it, gear shifting is smooth.

I went straight to Stage 2 TCU, Intercooler Boost hoses, turbo muffler delete, Intake, and catch can. My R is loving it :)

You'll love your vehicle even more.

guess that's why I am asking. seems most people do it when going stage 2 or higher or additional mods. my plan is stage 1 only. I will never go stage 2

I had Stage 1 for maybe a week, did that and TCU first with all the mods above, following week stage 2 prolly should've been more specific, my mk7 gti I did the same thing it's worth it. There's always a 30days money back guarantee too.

anyone just running the APR stage 1 w/o the TCU upgrade that wishes they did the TCU or is it just fine?


I have a manual so i cant comment from personal experience, but most people say the TCU tune is so much better than the stock tune that, given a situation where they'd have to choose between ECU or TCU tune, they'd leave the engine stock and tune the trans.

Do both at the same time. I have Unitronic stage 2 ECU and TCU and it's awesome.

i say yes. in my case when i tuned ED stage 1.5 i notice the car was cutting out in first gear and second. that completely went away with the tcu tune. it was like the stock tcu was limiting torque output

I didn't do my TCU tune until I was at stage 2. At first it takes some getting used to. I have the APR TCU tune and at low speeds (Street speeds) it shifts very early. Like 35-40 mph it's in 4th gear. That's to save fuel. But when your hard on the gas it shifts at higher rpm's. Like I said it takes some getting used to. But I've had it for quite sometime now. And it's well worth the money. My car is now apr stage 2+ pushing 400whp and I couldn't be happier with it.

Some have slipping, some don't. Since you only want Stage 1, I recommend going with JB4. If you burn your clutches you can remove the JB4 and still get your trans fixed under warranty.

Most of our customers that flash stage 1 only end up coming back for the TCU upgrade. The end result usually goes like this... "why didn't I do this at the same time" Well I appreciate both the ECU and TCU upgrade in their own respect. I like to see what each does on its own. You get used to the power of the stage 1 and find yourself finding the limitations you weren't expecting from the factory software.

The APR TCU upgrade is definitely a must have if you run APR ECU software. If you have any questions, be sure to let me know. :cool:

Thanks,

Greg

On the stage 1 tune for the Golf R, absolutely worth it and frankly, should be mandatory or sold as a package deal in my mind. The responsiveness in changing gears and ability to put more power down is a HUGE benefit. If you care about such things, the ability to customize shift points (up/down) along with 3 diff rev limits for launch control is pretty damn nice also. I had the TCU program on my KO4 GTI from the day the program was released and never had a single issue, only good times.

I have a GTI DSG and had the APR Stage 1 91 High ECU tune for about 3 weeks without the TCU. I read mixed reviews so I held out. I would basically say it can work without it but isn't truly up to the task.

In my experience, when in 'D' and upshifting during normal city dirving, momentum would drop abruptly between gears and it mostly upshifted to below 2000 RPM. Immediately after the APR TCU tune I noticed 'D' mode shifts were smooth and shift points consistently stayed above 2k in moderate to heavy acceleration. And the biggest improvement after the TCU tune was how it responds now to throttle input - it stays in the same lower gear for an extended time when giving it juice, whereas before it would force an upshift WHILE getting on it (that probably annoyed me the most, felt like I surrendered all the new power over to the stock DSG MasterLord, haha).

Yes. I wouldn't say I bought into that statement at first, but hey, it happened to me.

I have exactly the same sentiment for the GTI. The matched shift points alone makes it a winner.

On a related note, and a rant of mine, the modern pre-ignition phenomena in DI turbocharged cars, LSPI, is worth putting on your tuning safety checklist. When an ECU tune unleashes power for a time in the LSPI zone (technically 1500-2000 RPM; most dangerous in high gears at highway speeds) it becomes all the more important to watch shift points and lugging, far more than the average "good" driver does. The sense of having plenty of power in low RPMs is a false sense of security. I found overall that the APR TCU tune matches the additional power quite well and is much better at adjusting to road inclines. You might consider a TCU tune as protecting your investment.

Happy motoring!!

Yes it's worth it. Prior to the DSG tune the car was out of sync. The DSG tune fixed that.

Yes! I haven't gotten tuned yet but this annoys the heck out of me about the stock software. It races to high gears while getting on the power.

LOL.. I said the same thing..:D

APR TCU tune is worth it. IMO, If you're going to do something, do it right. If you dont want to pay full price, wait until their software sale comes up and they have their tax return sale on other parts too;)

I have a 2018 GTI SE DSG and have both the APR Stage 1 ECU and TCU tunes. I like the TCU tune for the most part (power wise) but there are also some things I don't like. Of course we all know there are the drive choices on the touch screen (ECO, NORMAL, SPORT) and also two separate automatic drive "modes" (Reg Drive and Sport Drive). I have found that the Reg Drive is pretty much worthless with the TCU tune in my opinion and this was also the opinion of the technician who installed the APR tunes and test drove the car after installation! In Reg Drive mode the thing will shift into 6th at like 40MPH, 5th at 30-35, 4th at 25-30! This didn't really bother me that much as I was never going to be out of Sport Drive at all unless I forget to put that in place before I go (and I always keep in in the SPORT choice on the touchscreen). BUT, the Sport Drive shifts also give me some issues as I have found that during daily driving conditions it will shift from 3rd to 4th at 38 MPH and 4th to 5th at around 54/55 MPH. Also sometimes at these speeds the tranny seems to not know what gear it wants to be in and goes back and forth causing a "jerky" motion/feeling. It also does this sometimes between 2nd and 3rd. Of course all of that goes away if you use the Manual Drive and shift yourself from either the paddles of the gear lever. Anyone else have these issues? I wish you could program it that in SPORT Drive it would go into 4th around 42-44 MPH and into 5th at around 58-60 MPH!

I know you just spent the money on this so you don't wanna spend more, but you can get a custom TCU tune if you'd like. The other day someone left a glowing review of an E-tuner that's new to the MK7 scene, but it seems that he's gonna be in high demand since his price for a CUSTOM TCU tune is less than an APR or Unitronic CANNED tune, and he can personalize your tune to your desires.
