Ive just bought a new FCD for the 7mgte, does anyone have any idea on how,what and where to wire this thing up. Everytime I try and boost her up a little, the Fuel Cut Off kicks in - Ive just gotta get this FCD to work !! Any tips would be much appreciated !!!! Thanks

does a fcd remove the top speed fuel cut thing or does it just let you run more boost out of your turbo ?

fuel cut is initiated by the computer when too much airflow is introduced to the engine (cuts fuel)

when going really fast... that's called speed

and when you hit a cut at speed it's called speed cut in which case you need a speed limit defencer

If I am going to increase the boost and I will eventually, how do I defeat that sensor?

well that depends

some ppl like to just get a boost controller on there and turn it up silly and have no fuel upgrades to support it therefore when they stick on the fcd they end up running a bit lean and then boom! funs over

other ppl are prepared for a fcd and buy a walbro pump and raise the boost max to 12psi (depending on what mods) and install a fcd and never alter their boost controller

basically you need to tell us what mods you have in order to suggest when you need the fcd and what boost you can run as it varies alot
if you have a dyno nearby that would be even better but not everyone has those
or if you have spare money to burn buy a wideband so you can keep an eye on it

Bit of a street racer, I guess. I'm told they're fast. Delivering it home with a friend driving the Supra for the first time. I drop gears and make a scream from the twin pipes flowing down this pony's flanks and it takes off like it's tail's on fire. I look back when the Honda gets to its tap-out and the Supra's only two lengths behind. No one I've let ride my bike has told me its slow, they've all loved the thing. That car is a good thing indeed.
