Took the car for a test drive today. Mild panic when the odometer didn't seem to be working as I drove the car down our laneway, but I hit the trip odometer reset button and now it works. Maybe the gears just needed to be reset after installing? Who knows!
Also confirmed the Turbo+ kit is not kicking in as the boost sits at a max of about 6 psi. There was one wire on the Turbo+ kit that went to a test terminal on the LH2.2 injection harness, but that doesn't exist on the LH2.4 harness, so I wasn't sure where to connect it…that may be why it doesn't work. I suppose I could just do a simple relay setup using the WOT earth signal to activate the T+ solenoid valve, and not worry about the "over 3750 RPM" criteria. I'll test the solenoid valve as well as hot wire it to see what happens to the boost when the valve is open.
The car seems to have plenty of power (relatively speaking) with only 6 psi of boost, so I imagine if the T+ takes it up to 10-11 psi it will be really noticeable. 🙂
