We just have another customer take advantage of the “powerplay” program we have in place to offer a discount to upgrade to APR Stage 2+ from a competitor’s software. This mainly came about after so many people asked to switch due to the lack of hardware support from the other tuners.
Same car, two different maps (APR and “competitor”), Both DSG and both on 99 RON which is Shell V-Power in the UK.
Blue = Competitor
Red = APR Stage 2+
Awesome GTI’s 4 wheel dynojet dyno with a DSG S4.
Gains were roughly 40 AW ft-LBS of torque and 40 AWHP. I’m not sure what the strange spike in power is at the end of the “competitors” run (perhaps ignition “tricks/risks” for high dyno figures?), but with the spike peak power is 20 AWHP up with our map and pulley.
BTW, I’m not really posting this here to advertise. I posted it here because I thought it would be an interesting discussion based on the hooplaw I hear all the time about “their stage 1 cal is as good as your stage 2 cal”.
I’m not going to name the tuner publically, but you’ll figure it out.
If you mean dyno printouts, certainly not. The APR2 car crushed it.
If you mean acceleration, the jury is out till we see the car accelerate vs. each other, or see the same car do a standardized test before and after.
If you mean safety, take a trip over to the logging thread (or search ‘I killed my engine’ on audizine)
Arin, Can you tell us what you are running on your personal car and what the APR race car runs?
Your car = stock cats, 034 test pipes, 034 HFC’s, Eurocode headers, or something else?
APR race car = stock cats, 034 test pipes, 034 HFC’s, Eurocode headers, or something else?
Thanks!
whoops… I posted in the wrong thread… sorry for the hijack…
^^^You guys have carried the flag nicely for APR B8 S4 products. It’s nice to see the manufacturers go and prove the parts work, but at this point for the B8 S4…I struggle to see the benefit for APR hitting the strip unless it’s with the Stage III kit as part of the launch. For that I would certainly expect them to do it.
But to go stage 2, maybe they go and unseat a customer from one of the top spots on the list, and raise the benchmark (that they already own). No point.
I had 034 testpipes at one when stephen owned the car but we removed them. It was to loud.
Race car
APR Motorsport Calibration (98.5 octane) - Similar to stage 2+ v2.2 software. Boost per the rules. Full bosch motorsport brake controller (required extensive ECU work), no cold start or catalyst heating, some driver ‘comfort’ features removed or altered, some component failure limp mode conditions removed or altered, we also alter thresholds on several temperature related items where cylinder, exhaust and motor temps can get higher before intervention and the intervention is also altered (Essentially, this is where some of the ‘accelerated life testing’ comes into play by seeing what the motor can take). Knock sensitivity completely stock. I don’t believe any of our race calibrations for any of our race cars has ever altered knock sensitivity.
APR Pulley
APR Carbonio Stage 1 & 2 Intake
APR Motorsport Custom Exhaust (Stock diameter per rules)
APR Full CPS System (The last race we upgraded the system further given we have so much room to work with)
Stock headers
Testpipes (I believe these are still 034, and I believe they are beefier or something)
Some items removed from engine bay. (mainly emissions stuff)
Could you give a brief explanation of the cold start /catalyst heating being removed? Is that something we can have (do have)? What benefits are there to this? I have an idea of what it is in my head but just want to be sure.
Cold start is for emissions to light off the catalyst in the morning. Basically it’s the whole loud start, high RPM and poor mileage scenario you have each morning.
We really don’t offer this to the public on the B8 S4 right now. No one has really asked anyways.
yea the secondary air injection removal. we wouldnt really beinefficientit much from it other than removing some hardware. call me crazy but i love cold starts, very fun.
Arin, does APR have any other products coming out for the 3.0t or is it after stage 3, is that all we are going to see? i would love some test pipe options that are actually 2.5" or larger. also any plan for tune 3.0?
