APR Releases OEM Golf R/S3 IS38 Turbocharger ECU Upgrade for GTI/A3

Product Page

APR is pleased to present the OEM Golf R/S3 IS38 Turbocharger ECU upgrade for GTI/A3 platform vehicles!

APR’s IS38 Turbocharger ECU Upgrade is designed for use with the factory Golf R / S3 turbo on GTI/A3 platform vehicles and produces an asphalt-shredding 386 HP on 93 octane fuel, and over 400 HP using APR’s upcoming Ethanol Flex Fueling upgrades! It’s even compatible with the factory downpipe exhaust system, at lower output levels. Expect lightning fast response coupled with smooth daily driving and a much broader power band that pulls all the way to redline!

Using multiple vehicles across the world and in house, APR’s team of Calibration and Electrical Engineers spent the better part of a year mastering the factory Simos 18 engine management system to work seamlessly with the upgraded IS38 turbocharger unit. All critical aspects of the vehicle’s platform were taken into consideration and monitored through APR’s proprietary engine management logging tools to levels often not seen elsewhere in this industry. Through proper mapping, the ECU fully understands the hardware changes and operates correctly. As such torque delivery is smooth and flat, avoiding compressor surge, limitations in the factory fueling system, and limiting stress on the factory transmission. Cam phasing and valve lift operations are optimized, aiding in turbocharger spool, while allowing the engine to breathe more efficiently at higher engine speeds. Under various operational modes, lambda, ignition advance, requested torque, boost pressure levels and more were painstakingly optimized to produce maximum power without resorting to risky calibration shortcuts.

To APR’s Engineers, this is the ultimate pursuit of performance without compromise. To the driver, it just works!

With OEM Downpipe
Wheel| Crank| Gain over Stock– 91 AKI / 95 RON
Wheel| Crank| Gain over Stock– 93 AKI / 98 RON

– APR recommends and tuned with Sunoco GT 260 for 100 AKI mode and Sunoco GT 260 Plus for 104 AKI mode. Never use lower octane than specified by the mode.
– Ethanol software REQUIRES APR’s upcoming Ethanol Flex Fueling upgrades.
– Max increases are based on APR’s actual measured stock values and not those reported by VAG. | RON = ROW Fuel Grades | AKI = NAR North American (RON+MON)/2 Fuel Grades.
– Reported wheel figures measured using APR’s in-house Dynapack Dynamometer with a US Spec MK7 GTI with factory IS38 turbocharger, APR Cast Downpipe, APR Intake System and APR Intercooler, using SAEJ1349 correction and an average of multiple runs. Crank figures are estimated based on the measured wheel figures. Results may vary depending upon environmental conditions, vehicle, transmission, vehicle health, operating conditions, temperatures, fuel grade, dyno type, dyno setup, other variables and other modifications.
– Race Fuel Information: Higher octane fuel typically allows APR’s engineers to create more power and torque by achieving greater ignition advance. However, on this application, APR’s engineers were able to achieve MBT, or minimum spark timing for best torque, on 93 AKI fuel with the APR downpipe. MBT is essentially the point where greater ignition advance no longer results in more power and torque. By using APR’s upcoming Ethanol Flex Fueling upgrades and Ethanol fuel, greater peak power was achieved due to the fuel’s highly oxygenated nature.

Requirements and Recommendations

APR’s IS38 Turbocharger ECU Upgrade is sold as software only. The factory turbocharger necessary for this upgrade is conveniently available at various APR dealers and VW, Audi and Seat dealerships across the world.
– Turbocharger – An unmodified, OEM IHI IS38 Turbocharger is required. APR recommends using the latest factory revision (06K145722H as of Oct 20th, 2015) with APR’s Turbo Muffler Delete and recommends replacing factory one time use nuts, bolts, gaskets, and crush washers.
– Intake – The APR Carbon Fiber Intake System>is highly recommended. This setup is necessary to achieve the advertised power figures.
– Exhaust – Upgrading the factory downpipe is required for the higher output downpipe software. APR highly recommends using the APR Cast Downpipe System as this system is necessary to achieve the advertised power figures. The factory catback exhaust does not need to be modified.
– Intercooler – Upgrading the factory intercooler is highly recommended. APR recommends using the upcoming APR Intercooler system. This setup is necessary to achieve the advertised power figures consistently.
– Ethanol Support: – APR’s upcoming Ethanol Flex Fueling upgrades are required to run Ethanol calibrations. No fueling upgrades are required for conventional gasoline.
– Spark Plugs – Upgrading the spark plugs with Denso Iridium IKH24, gapped to 0.024″ ±0.002″ or 0.6mm ±0.05mm with a change interval of 10-15,000 mi or 16-24,000 km is required for engine longevity and safety.
– Transmission – APR recommends the APR IS38 TCU Upgradefor maximum performance on DSG / S Tronic models. A clutch upgrade may be necessary on manual transmission vehicles.
– Oil, Coolant and Lubrication – APR recommends using Motul oils, coolants and lubricants>with APR’s Oil Catch Can System.

Application Guide
– Audi A3 – MK3 / Typ 8V
– Seat Leon – MK3 / Typ 5F
– Skoda Octavia / VRS – MK3 / Typ 5E

2018 Lamborghini Aventador S Roadster Review

“Supercars just don’t excite me anymore.” These words, spoken to me over a month ago by another journalist, friend, and (so-called) enthusiast were echoing in my head for far too long, but they’ve finally been drowned out. Drowned out by the wail of a naturally aspirated 6.5-liter V12 engine mounted in the middle of the new Lamborghini Aventador S Roadster. My friend’s point is that back in the good old days, there was a crop of supercars that captured the imagination with amazing style, sounds, performance, and more. Today, it seems like everything is capable of supercar performance, with large luxury sedans outdoing some of the best and most dedicated teams of car nuts, while former pillars of automotive excellence are suddenly pumping out family-friendly SUVs. Beyond that, another league of supercars, dubbed hypercars have cropped up with hybrid gas-electric powertrains that make magical things happen quickly, but at the cost of the acoustic drama, visual flair, and engag...

Project SportWagen: Going Stage 2 with APR

    When we last left you, the humble little SportWagen was fresh from the development process with our friends at AWE Tuning, sporting a new downpipe, exhaust and intake, allowing things to breathe a bit easier.  The car sounded great, but there was no getting around the fact that our wagon was still quite, well, slow.   While we realize that nothing we do to the Golf SportWagen at this point will make it a race car, we still felt compelled to do something .  To put it bluntly, we had a fever, and the only cure was more power. Flash forward a few hours, and we found ourselves at Waterfest, staring down APR’s palatial spread and the numerous tuned vehicles surrounding it.  Earlier in the year, APR had hinted to us that their 1.8 TSI files would be quite impressive, and based on what they were able to do with the 2.0 TSI found in the new GTI and our time in their Golf R, we knew it’d be worth the wait.  So with this in mind, we lined our G...

Project Golf SportWagen- Intro

I’ve never really been one for SUVs and crossovers.  The current offerings aren’t the body-on-frame, go-anywhere specialty tools I remember from my youth, and what they lack in capability, they also lack in on-road performance. The current crop isn’t terribly good at handling or being efficient, which in my opinion are major components of our ideal driving experience.  So when it comes to space or utility, I usually look for something of the wagon variety- and it seems that I’m not alone. We hit quite a few shows around the east coast each summer, and we see modified Jetta SportWagens at nearly every event. Even amongst common consumers, these cars are highly sought-after. They don’t depreciate much, making even early Mk 5 2.5 versions expensive in comparison to other Jettas or Golfs of the same vintage. This year, Volkswagen launched their latest SportWagen, which is now billed as a Golf.  In many ways, this latest SportWagen is the best yet and it has certai...
