adjustable boost/fuel cut defence

[super.secret.supra.club]

i have searched and found nothing that will help me.

has anyone ever made a fuel/boost cut controller that can be adjust like the greddy bcc.

basically i want something that i can raise boost/fuel cut with while still having it as a safety feature, unlike the HKS FCD.

thanks edd

Are you looking for the 1J, 2J, or 7M? You've got all 3 in your sig, which one is yours?

The safest and easiest way to make power past what the stock system will give you is getting the Lexus AFM setup. You're looking for an AFM from the SC400 or LS400 (I don't know the specific years off the top of my head, but it's out there if you search). It's the same electronics as the Supra's AFM, only in a housing that is roughly 25% larger. Pair that with 550cc injectors (25% larger than the stock 440cc), and you've got a close match. You'll likely want to bump up your fuel pump to a higher output pump and get and adjustable fuel pressure regulator so you can be safe of not starving the bigger injectors. You'll also want to do the j-tube mod (search it, there's plenty of info on it) to eliminate some restriction with the extra flow. Do the fine tuning with a fuel management such as the SAFC, and you're good to go. Strap on a bigger turbo and you can make 400rwhp pretty easily with that sort of setup.

What sort of fuel mods are you doing? What kind of power are you aiming for?
