APR "Power Play" Tune Swap

**GRUMPY-S4** · 10-04-2016 05:19 AM

Comments on this offering from APR for people to switch off their current tune for ~ half price?

Will you have to use the APR pulley instead of say the CTS pulley? What if you have a JHM 179 crank pulley or another version of the crank pulley installed?

Wonder how the APR race file would run on some sort of E85 blend. Anyone done this?

Arin has been pretty responsive in the "boost season" thread. You might want to ask him about your hardware concerns. I don't think anyone outside of APR could answer them at this point. As far as the E85 blend on the race file, wish I could help. I can say I've been mixing 2.5 gallons of E85 to every fill up on my 93 octane file without any codes. The car seems to really like it. I can only imagine the results would be somewhat similar on the 100 octane file if you mix properly.

Yeah I am interested in knowing more about this as well. The post on the APR website for this is from October 2012, so I'm not sure if it still exists as I asked APR about this earlier this year and they said no such program is around. https://www.goapr.com/news/2012/10/3...si-power-play/

The wording pretty much says that the price includes the APR Pulley. Obviously it would be unfair to APR's current customers to be able to buy the CTS pulley and the APR Stage 2 software, which is why they are sold together. But if you have purchased a competitors product and could then purchase the "Power Play" package at ~$1,299 (with or without the APR pulley), I suspect there would be a decent amount of people making the jump to APR in advance of the Ultra Charger release. All APR would need to do is set current pricing, maybe a program with and without the APR pulley, and each customers tune would need to be verified at a dealer. Great sales strategy in my opinion.

I believe that OnEagerBunny may have posted a while back in the "Life Beyond Stage 2 thread" about trying the race file with E85 but I'm not 100% sure on that

I didnt notice that the post on their site was that old. Interesting.

Right, he did too! That's extremely encouraging, have already sent an email to my APR dealer.

I wonder if the US pricing is still the same as shown on the website.

Big question is pulley, APR needs to stop requiring people to used their pulley.

I somewhat disagree with this. Reason is APR strives on fit and finish, and OE reliability and performance. If they're selling a tune created specifically for their hardware they want to ensure it works exactly as it supposed to. This also helps with technical issues and trouble shooting down the road. Other hardware is out of their control and there's no way to guarantee the software working as it was intended.

Same reason they don't advertise selling their stage 3 files on their turbo cars. Selling a tune for a car that's setup with completely different parts then what the tune was created for is just a recipe for trouble.

Now I understand we're talking about a pulley here and the ECU has the control of what's going on but I get why they do it. One solution would be to offer a no warranty or tech support for those running hardware other then APR, which I'm sure most would have no problem with. The issue here is that still doesn't stop people going on the internet complaining about a tune not working when the real problem is the hardware installed doesn't match the tune. I've personally seen this many times on 1.8T's...still see it today... people complain the cars not working right because of X brands tune, I start questioning them about the hardware on the car and of course they have changed the throttle body, Fuel Pressure Regulator or are running the wrong injectors.... no wonder the car isn't running right.

For $1,300 surely you could just buy the Power Play and not install the pulley if you dont want it

APR have already confirmed that the Ultra Charger won't need the full APR supercharger-crank pulley combination

It's a pulley, not rocket science.

Other tuners don't have an issue.

Ecu bleeds off the boost it doesn't want anyway.

Didn't say it was, in fact I state nearly the same thing as I'm well aware of what the ECU does. My point was... as a business it's one more thing to help protect their tunes to work as they're intended.

You can mix on the APR tune though I only ran 93/e85 once on the 100 map (IIRC it was e34 but there could've been some residual race gas in the tank when I filled). That was in the video where I raced the c63 amg and camaro.. I had the Apr upper and Jhm lower without the CW at the time. Results were pretty good. I had the file maxed out in terms of timing.

Once I added the CW, almost every tank I ran was 100 octane + e85 for a ~e25 mix on the 100 map. Very good results with that mix both on the 179mm and 194mm cranks.

You will be purchasing an APR pulley, it is your choice whether or not you use it. Without a new pulley, no way to flash your car to stage II (each pulley has an auth code that allows stage II to be paired to a VIN).

You may not get optimal results with a different pulley, the risk you will assume.

APR race file is designed for 100 or 104 octane race gas, it would be very wise to log your results if you are looking to do some sort of blend of fuel. There may also be risk that you must assume.
