Supra BPU fuel cut issue

Ive recently in the last few months gone to BPU on my 1999 JDM TT6 VVTi supra and have a a lot of fuel cut on high boost and now on low boost. I've gone to TTC mode on the turbos to see if that would solve the issue and no luck. I'm happy to stay on the TTC mode because I like the turbos coming in on one hit! I know it's not everyone's cup of tea but hey! I'm running a standard ECU with a HKS EVC-S Boost controller and HKS FCD. What are other people's recommendations on the best boost controllers and FCD's to run for stranded twins?

Any feedback wil be great!

Have you adjusted the dial on the FCD?

I didn't install the FCD myself! Is it easy enough to adjust the dial?

I would get a CW FCD and replace the HKS.

What peak boost readings are you seeing? are these different from what you used to see? If you are in TTC what is the boost controller doing for you?

Through a bit of ignorance on my part (and inconsistent boost control - I think it was faulty but can't be sure) I binned my controller (apart from it reading boost for me), limited the max boost with a restrictor ring, done the first turbo mod and then left it like that.

Mine came with a hks fcd fitted but the guy had used those scotch lock clips but they hadn't actually cut into any of the wires! He'd also looked at the pin out back to front so wired it in wrong anyway lol

Now I've wired it correctly and set the dial to 9 (I think!) It works perfectly on my bpu setup.

It might be worth checking your wiring before buying a new one?

Have you checked the fcd is actually installed correctly? I managed to get one wire wrong on mine years ago its easy done if in a rush etc
