Performance Chips - 94 to 98 993

 

Unleash the power of your 993 and discover the grunt and power the Porsche 3.6 motor is capable of. Eliminate the sub 4000 rpm lag, and make your car come alive. Have your engine 'come on the cam' right off the line, with a very significant increase in low and mid range torque and throttle response, vastly increasing everyday drivability and usability. Capable of breaking rear wheel traction with the crack of the throttle, discover low rpm throttle steer from your 993 at your next autocross you never knew your car was capable of! Owners of 94-95 993s have described the change in performance as feeling faster and stronger than a Varioram 993!

Guaranteed to outperform, all chips have a 100% satisfaction guarantee. All programming by default is designed for 91 (95 RON) or higher octane fuel usage. If programming for 93 octane (98 RON) fuel is preferred, please note your octane program preference in option window provided. Also, unlike some other chips, our chips will not trigger your check engine light. Guaranteed to outperform - even your current performance chip, all chips have a 100% satisfaction guarantee.

Stalling from the installation of a lightweight flywheel and clutch is now history, guaranteed to be fixed by our latest most advanced program solution, or your money back. Not only do you have to worry about stalling from the RPMs subdipping below idle on decel and between shifts, but our newest code actually helps with clutch engagement off the line without excessive clutch slip - minimizing wear, while further compounding the throttle response potential of the lighter flywheel and clutch. Former customers are welcome to have their chips updated free to the latest LWF coding. Contact us for further information. . Please select the appropriate setup in the option box below.

Want to disable and delete the car's Immobilizer/Driveblock system in 993s equipped with this option? Does starting your engine become tedious each time because you are required to turn off the Immobilizer each time with the key fob? The non-Driveblock chip versions below will eliminate and disable this, reverting the car to just as non-Driveblock cars came from the factory, You will need to install jumper relay 964.610.184.00 into the car's relay socket R61 just as factory.

Chips customized and specifically dialed and tuned into your motor available in the Custom Chips and Dyno Tuning section.

Installation Instructions - 94 to 98 993

 

Note: Porsche used six different DMEs on the 993 for the 94-95 model year. To order the correct chip, please match the numbers on top of the DME box with the corresponding list below. The DME box is located on the floor under the left front seat. The numbers are printed on a label on top of the box with the word Motronic on top.

Performed on a Dynojet 248x, a '95 993 dynoed with the stock chip the engine produces a max of 232 hp, or 273 hp corrected to the engine calculating for a 15% transmission loss (red curves). With our remapped chip, the engine now produces a max of 247 hp, or 291 HP corrected to the engine, a 18 hp gain over the stock chip (blue curves). In addition, broad range torque has increased from 10 to 20 ft-lbs throughout the rpm range.

 

 

Dyno tuned at Ed Pink Racing in Van Nuys, CA, this pristine all original '95 993 with only 20k original miles on the odometer was live mapped and dyno tuned on their Dynojet 248x. After final tuning the car produced 271.5 hp at the rear wheels (light blue). For comparision the factory stock chip was dyno tested afterwards to only produce 253.75 hp at the wheels (yellow), a difference of +17.75 additional hp and +12 ft-lbs of torque (green) at the rear wheels with the retune, or over +20 more hp at the flywheel, in addition to the much more optimal air/fuel ratio curve throughout the rpm range (dark blue).

 

 

 

*dyno tested with 91 octane

 

 

 

Other configurations available upon request, including special modifications such as custom rev limiters, displacement increases, and 100+ octane race fuel. Air/fuel ratio optimization based on the afr readouts of your dyno sheets are also available. For these options, a personal consultation may be necessary with fees for custom programming services ranging from $950 and up. Submit your request on the contact page for further information.
