Thank You for the add
After waiting 28 years I finally got my Dream Car 1993 Mazda RX-7 with 56K miles. It was installed with bigger injectors and the Wolf 3D ECU 4.0 Version. Now I'm trying to get the software for the ecu to be able to adjust the boast higher than 4psi. Any help would be appreciated. I need to also fix my Tach and speedometer. Also looking for the diagram for the Bose system to see if I can get it to work with an aftermarket deck.
