1999GS300T

Hi, I'm new here. I've searched here and on Supra Forums--but cannot get a definitive answer. I've got a 99 GS300 with the Aristo 2JZ-GTE swap (engine, trans, ecu, e tc).

I've seen posts about diodes, Greddy BCC, HKS FCD, etc. However, one person says this version doesn't work with the Aristo ECU and this person says it does.

Is there anyone who has this setup or knows about it enough to say what will raise or eliminate the fuel cut past 14psi (besides standalone ECU)?

Thanks!

HKS FCD, buy a new one because they do go bad. Nothing worse than trying to chase a problem with a faulty part to begin with.
And since you plan on going past 14 psi you will want to get the HKS SLD while you're at it. Or you would just get to 110MPH a bit faster than stock.

Ok cool. Do you have this setup on your swap? I forgot to mention my motor is also VVTI. Does that matter?

I don't need it, running stock ecu with stock 5 speed auto, AEM infinity 6 to control the motor. The only speed cut I see is at 145mph.
