Re: boost solenoid

12v from car and ground it to egr A11, you needf egr components in your ecu and software that supports boost control, like ectune or neptune. This is for OBD1 system. Im runnin 89 EF with p28 / egr components / ectune / mac solenoid from ebay. 1st gear 12psi 2 gear 15psi rest 25psi but im having less boost at peak torque to get better traction.

Installation:

•Connect the pressure source to the 'bottom' of the wastegate (were the pressure will act to open the wastegate).
•Tee the pressure source and connect via the solenoid to the 'top' of the wastegate.
•Try to place the solenoid close to the wastegate and keep the tubing reasonable short (but do not place the solenoid where it will get hot). Tubes which are around 6-18 inches long will work fine.

Wiring the Solenoid

The solenoid has two wires, with no polarity (it does not mater which wire is used for each connection):

•One wire should be connected to the ECU pin A11. Note on OBDIIA ECUs the corresponding pin on the vehicle harness side is A7, and for OBDIIB ECUs pin B7.
•One wire should be connected to +12V switched power via a 10A fuse.

Notes:

•Do not use a relay between the ECU and solenoid.
•High current solenoids could damage the ECU. It is recommended to confirm that the solenoid draws the same or less current as the GM solenoid listed above (around 3A).
