chilli Posted October 10, 2005 Share Posted October 10, 2005 After double decatting my car recently and running around 1.1 bar for a few weeks I was begining to think that I was lucky and that either my fuel cut limit was higher than normal or that I already had a FCD installed from Japan. Much to my suprise last night I discovered that neither were true lol. The colder evening saw around 1.15bar and whilst flat out in 4th, Wham - fuel cut! This sure is abrupt isn't it! a bit of a shocker to say the least, quite a jolt to the car and the dash lights up like a christmas tree too... Anyway I've overed the Thor VFCD now, should have that installed ASAP I just wanted to warn all those potential de-catters out there, be prepared for this one, it's quite alarming if your not expecting it and could be v.embarising if you're out showing a fellow spirited driver what the supe is capable of!!!

tbourner Posted October 10, 2005 Share Posted October 10, 2005 Yep, after the decat I hit fuel cut once. Had a TRL VFCC in my footwell within a week! Quote Link to comment Share on other sites More sharing options...
Wez Posted October 10, 2005 Share Posted October 10, 2005 The TRL is ok aslong as you are not exceeding 1.2 - 1.3 bar of boost, if you haven`t already i would invest in a restrictor ring and then use a boost controller to raise it to the desired boost. This is more of an issue on the J-Specs due to the ceramic turbos, not so much of a problem on the UK/US cars. Quote Link to comment Share on other sites More sharing options...
chilli Posted October 10, 2005 Author Share Posted October 10, 2005 Cheers for the advice, I've already got a restrictor ring fitted. I don't think it will be going above 1.2 bar, it was hovering around 1.1 and just creeping over at peak revs probably due to the cold weather... If it goes up any more I'll be sure to fit a slightly smaller restrictor ring though to keep it at/below 1.2bar Quote Link to comment Share on other sites More sharing options...
BURT Posted October 10, 2005 Share Posted October 10, 2005 oh yeah fella hit it too, scared the feck out of me, thought i'd proper fucked my baby!! Quote Link to comment Share on other sites More sharing options...
Nic Posted October 10, 2005 Share Posted October 10, 2005 Sounds like your boost gauge is out, should be hitting fuel cut at 1bar. My Defi gauge is out compared to readings on my boost controller by about teh same margin. Quote Link to comment Share on other sites More sharing options...
Scoboblio Posted October 10, 2005 Share Posted October 10, 2005 From previous posts, I don't think the fuel cut kicks in straight away, you need to exceed 1 bar for a few seconds before it'll do anything, this could be why you didn't get it before. Then again I could be talking out of my arse Quote Link to comment Share on other sites More sharing options...
hogmaw Posted October 10, 2005 Share Posted October 10, 2005 I am still waiting for my FCD after about 2 months and will name names if it does not come soon cos the LAST thing I want is this to happen to me while in the outside lane...!

chilli Posted October 10, 2005 Author Share Posted October 10, 2005 where you getting your FCD from then hogmaw? I've just ordered mine, sure hope it turns up asap. Nic, you could be right but its a decent guage (apexi) and the restrictor ring was set for 1.2bar so it roughly adds up, I think fuel cut can vary a bit from car to car? Yes seems its not based on absolute peak pressure since I think I've seen it peak momentarily over this, but in 4th gear or higher you get long enough time on full boost to hit fuel cut. Perhaps if/when it goes to the tuners then I'll get the guage checked though just in case... Quote Link to comment Share on other sites More sharing options...
