APR DQ381 7-Speed Front Wheel Drive TCU Upgrade (IS20)!

August 16th, 2019

dq381_fwd

APR is pleased to present the ultimate Transmission Control Unit (TCU) Upgrade for the DQ381 7-Speed DSG / S-Tronic Transmission on FWD vehicles like the MK7 Golf GTI and Jetta GLI!

APR’s TCU Upgrade dramatically improves upon the DQ381 transmission’s function, drivability, and performance through a myriad of enhancement and custom features. Normal daily driving is smoother as we’ve improved upon the normal quirks and complaints associated with the driving experience. Sporty driving is far more capable with increased torque capacity, clamping pressure, faster shifting times, more capable launch control, and more, handily shaving .2 seconds off our Stage 2 S3’s quarter mile time! Both are optimized to deliver faster acceleration by matching the power output delivered by our ECU Upgrade. This all comes with customizable features you can choose while flashing the TCU to personalize the transmission to your desire! Lastly the software loads to the factory TCU through the OBD-II port, resulting in a clean and headache-free install. See our full feature list rundown on our product page.

For vehicles with an APR Race DP and APR S6/S7 Catback Exhaust System, or APR RS6/RS7 Catback Exhaust System, the APR X-Pipe is a must have. This upgrade creates a smooth transition between the two systems and integrates an x-pipe that reduces backpressure. This upgrade smooths out the exhaust note for a more refined sound profile while also increasing peak torque. Like the rest of the system, the x-pipe is constructed from T304 stainless steel, beautifully TIG welded, and includes all new APR slip clamps. Purchase one here today!

2.5 TFSI EVO RS3/TTRS – Upgraded MPI Injector Testing (Stock Turbo)

August 2nd, 2019

rs3_injector_test

We’ve seen a recent uptick in customers asking for a “Stage 2+” tune designed for upgraded MPI or port injectors. The theory being power is held back due to a lack of fueling with the factory fuel injectors. Seeing as this would be easy to prove, or disprove, and potentially an additional product we could offer, we set out to test the theory.

We first conducted as series of baseline testes on a Stage 2 RS3. Then added larger port injectors and started tuning Stage 2+. Thankfully conditions were nearly identical during the tests. Stage 2+ had a slight conditional advantage, but not enough to make a real difference. Using normal pump fuels (91 and 93) unfortunately there were no gains to be had. The same held true for race fuel (100 and 104). The factory direct injection system has enough fuel to fully satisfy the needs of these tunes. Using more port injection, when unneeded, unfortunately has the drawback of actually hurting performance. Typically, we see the turbo spool slightly later, and a slight drop in overall performance.

Next we tuned using full E85. Unlike traditional gasoline, E85 requires about 30% more fuel. If we’re fuel …
