digital tuning, inc. is proud to offer a line of RX-7 ECU upgrades. The Rtek7 ECU Upgrade is a replacement ECU chip for Second Generation RX-7s. This unique upgrade offers features not found anywhere else in such an easy to install system.

Chris Ludwig from Ludwig Motorsports sent us these dyno charts from an Rtek7 equipped S5NA. The only mods on the 95k mile car is an RB header (factory primary cat still installed) and the Rtek7 Stage 2 Upgrade.

After tuning the car, it made 46 more HP at 6500 RPM, just from tuning fuel!
