After all, he can always upgrade to stage 3 later!

He agreed but still had one big question… stage 2 or stage 3? Both are excellent packages but because he was still unsure of what stage he wanted on his ST, we recommended that he start with the stage 2 package. Our client was unsure of which product he wanted so we gave him our recommendation of the COBB Tuning package. This time it’s a customer looking to upgrade the power on his hot hatch.

Today we’re going over a customer with a 2014 Ford Focus ST who has been bitten by the mod bug! This entry was posted in Tech Talk, Tuning, Volkswagen GTI by Stratified. If you have any questions, don’t hesitate to Contact Us! We are also going to continue updating you on our development and tuning progress.

As we continue to develop for the GTI and have applied our years of direct injection tuning expertise, we are now offering pump gas as well as E85 tunes for the MK6 GTI which can either be packaged with a COBB Accessport or bought individually. Adding flow parts will give us some top end performance and we will see an even flatter torque curve. The DSG hardware is able to handle the extra torque we just need to program it as such!Įven without a DSG flash, the car has a lot of potential with just an ECU tune. The turbo is able to supply more boost and in order to achieve higher torque values in the lower RPMs, a DSG reflash is needed (and coming shortly). This torque limit is set to 350nm and you can see that we are riding this limit in the graph below. This is because we have reached the programmed torque limit for the DSG transmission in our test car. With the E30 blend we were able to achieve an additional 15whp and 26wtq on the bone stock car.īoost was maintained at similar levels but we were able to push timing to mean best torque (MBT) meaning that we were able to add timing until we did not gain any further performance while remaining knock free.Īt these power levels we are actually leaving some torque on the table between 27 RPM and this is why boost levels remained similar. On this blend approximately 10% extra fuel volume must be delivered and both the high pressure fuel pump, low pressure fuel pump, and injectors are up to the task of delivering the needed fuel on the OEM turbo. For this, we strapped the GTI down on the dyno and mixed 4 gallons of E85 with E10 91 pump gas fuel. On most direct injection cars, blending some E85 with premium pump gas fuel allows you to tune very close to MBT (mean best torque) and maximize both boost and timing (especially on a stock turbo). With the COBB AP it is also a breeze to switch between different fuel blends and tunes within minutes. Often an E85 blend and tune will net a very nice power increase. The engine is not very knock prone which is great to see and even on 91 octane fuel we were able to achieve very consistent results.īefore adding any bolt-ons we decided to increase the fuel octane and search for what we can achieve with an E85 blend. The torque ramp from low in the RPM range makes the car quite eager to accelerate and makes passing a breeze. The overall area under the curve gained however is what makes the car very enjoyable to drive. On 91 octane fuel we were able to add a peak of 32whp and 69 ft-lb of torque over stock and 24whp and 48 ft-lb of torque over the COBB OTS tunes. The car drives as stock until pushed and when it is pushed it delivers a smooth rush of torque that doesn’t fall flat in the upper RPMs. A lot of seat time and stress testing of the calibration backs up its resilience. We started by ramping up performance from stock by adjusting boost, timing, and watching all vital engine parameters such as knock, air fuel ratios, charge air, and engine temperatures. With a bone stock car (what is known as Stage 1) which just includes a reflash of the ECU you can get the majority of the power that the stock turbocharger can offer from just the tune. The car is very pleasant to drive and the first step to improving the experience is to add power safely and improve driveability. We have been tuning the MK6 GTI using the COBB AccessPort and working with a bone stock vehicle to start.
