The benefits of the TT Chip for the Mk3 2.0L ABA engines far exceed what can be shown on a dyno graph. Torque is increased at all points from 2000 to 6000 rpm, and peak horsepower is increased by 7-9hp. The engine's willingness to rev is improved dramatically. The rev limit is moved upward to 6900rpm, and the top speed limiter is removed. Try one and you'll know how nice this engine can run when given the chance! Have the VW part number from your car's ECU ready when you order. Our tech department is available to assist you in finding this number.
Have the VW part number from your car's ECU ready when you order and be sure to enter it in the order notes section. The ECU part number is located on the physical ECU. For Mk3 2.0L it will begin with 037-906-XXXX
The Ignition Map
The TT Chip takes advantage of available 91/93 Octane gasoline and incorporates a new, more aggressive, ignition map for your car. This is what produces most of the power gains in the low to middle rpm ranges and the "seat of the pants" improvement. Our ignition map modifications are not merely limited to full throttle conditions. Changes are made in the maps affecting both full and part throttle situations. Part throttle ignition mods are, in fact, the changes most responsible for engine responsiveness during most driving conditions. Why didn't the factory do this to begin with? Mainly because any factory must design their cars to accommodate the full range of available fuels. More recently, as cars become "world spec," using the same cars all over the world means an even greater range of fuel quality. As a performance tuner, we can design our TT Chip with a specific fuel quality in mind. This allows us to run more aggressively towards the performance ideal.
The Fuel MapPerformance Camshafts
Peak horsepower depends greatly on properly administered amounts of fuel. We design each TT Chip to provide enough fuel to produce maximum power, yet it will only provide the extra fuel when conditions find it necessary. Extra fuel at inopportune times not only reduces power, but also reduces mileage and increases emissions.
Got a performance camshaft? Techtonics has a specific CAM Chip available that is programmed for higher duration cams. If you have a cam installed please select the drop down option above.
Setting New Limits
Each TT Chip features a raised rev limit that allows you to take better advantage of other performance modifications, such as camshafts and exhaust systems. We do not totally remove the rev limiter, as some other chip makers have, because we feel it's extremely important to prevent over-revving and possible engine damage.
Where the factory has chosen to limit the top speed of some of its models, the TT Chip removes the top speed limiter and sets your car free.
All TT Chips are backed by an unconditional 30 day satisfaction guarantee. If, for any reason, you're not completely happy with your TT Chip, simply return it within 30 days of purchase for a prompt refund, hassle-free.
Limited Lifetime Warranty
Each TT Chip features a Limited Lifetime Warranty from Techtonics Tuning. You'll probably never need it, but it's there if you ever do.
