My new fuel cut defender arrived yesterday, so I spent last night installing it along with a bleed valve. The FCD was super easy to install - just intercept the MAP sensor wire, add +12v and ground, and that's it! The bleed valve was another matter though; the 2JZ has vacuum lines, solenoids and diaphragms all over the place, so it took a lot of trial and error to find the right place to install the bleed. I got there in the end though!
The first test drive was pretty interesting; we didn't know what the bleed valve had been set at, so I decided to briefly floor it in 2nd gear and see what happens. The tacho hit 7000rpm almost instantly and the boost gauge went off the scale - holy crap!! It sure felt fast, but I decided to wind it down a LOT and try again.
We eventually got it to hold a nice steady 17psi, and I'm pretty happy to leave it there. The FCD is set to fuel cut at 19psi so that gives me a bit of headroom. The car definitely goes very, very hard at 17psi... it breaks into wheelspin every time the second turbo kicks in. Yee-haa!!
Anyway, I'm taking the car to a dyno day on Sunday so it will be interesting to see how it performs. I dyno'd the car last weekend and got 263 rwhp on 12-13psi with lots of fuel cut at the top of 4th gear. I'm hoping to nudge 300 this weekend.
