ronttuk Posted April 22, 2015 Share Posted April 22, 2015 since installing the boost controller when i floor it on a motorway my uk spec auto cuts out for a split second at high revs i thought it needed a fcd but have been told by supraloopy being a uk spec it does not need a fcd so could it be fuel pump or something else? if you think it is fuel pump which one would i need it has, boost controller, fmic, dbl decat.

gordy.r Posted April 22, 2015 Share Posted April 22, 2015 Clutching at straws here with my limited knowledge but I'd start with looking at vsv's and turbo link pipes in case they are collapsing. Just a suggestion. Quote Link to comment Share on other sites More sharing options...

So if my supra is running a UK spec TT engine I don't need a fuel cut defender? As I have just literally bought one on the club to fit. I was recommended one if I was running a boost controller.

cered Posted April 22, 2015 Share Posted April 22, 2015 I thought all Supras had a boost limit or whatever to 1bar? My BPU TT import cuts out for a split second at high revs/speed so I assume it needs a FCD because it's going over 1bar Quote Link to comment Share on other sites More sharing options...
shaz2010 Posted April 22, 2015 Share Posted April 22, 2015 (edited) Ron mine was doing this when a double decatted my UK! You defo need the fcd mate, my bet is the coil pack clips! That was why mine was just keep cutting out when pushing her hard. When I replaced the clips I removed the fcd and I was hitting fuel cut when I would spike just over 1 bar. Then put the fcd back in and ran 10 mins later no fuel cut. Edited April 22, 2015 by shaz2010 (see edit history) Quote Link to comment Share on other sites More sharing options...

A UK spec does needs an FCD if you want to boost above 1bar (it doesn't need a restrictor ring, perhaps that's where the confusion has come from).

ronttuk Posted April 22, 2015 Author Share Posted April 22, 2015 thanks for the replies, i fitted new coil pack clips and plugs last year your not the first to suggest that but it made no difference,so next is to fit the FCD but ive been told uk wiring is different so how do i get a wiring diagram for a uk spec?
