Guest jaybe1 Posted March 7, 2006 Share Posted March 7, 2006 Im just after buying a 95 supra tt. Problem is when i floor it in 3rd gear upwards and hit boost the engine dies and orange engine light comes on. Could it be fuel cut ? I have a HKS evc 4 and dont know how to reset it. It boosts to 1.24 bar and even with controller off still does this. Any suggestions as to why this is happening ? Quote Link to comment Share on other sites More sharing options...
Jurgen-Jm-Imports Posted March 7, 2006 Share Posted March 7, 2006 what is the full spec of car any pics ? sound like fuel cut but mods list will help Quote Link to comment Share on other sites More sharing options...
Guest jaybe1 Posted March 7, 2006 Share Posted March 7, 2006 Still on stock turbos Greddy fmic(huge), boost controller thats all i know as it was brought in from japan. Boost setting were set at 0.9 bar low and 1.75 high but somehow i doubt it would run that kinda boost. When at 0.9 it still boosts to 1.24 cant get it to stable Quote Link to comment Share on other sites More sharing options...
supRo Posted March 7, 2006 Share Posted March 7, 2006 Can you switch the Boost contoller off? > What boost does it make with it off? Are both the cats out or still in place? Quote Link to comment Share on other sites More sharing options...
Guest jaybe1 Posted March 7, 2006 Share Posted March 7, 2006 both cats still intact. still seems to boost beyond 1 bar when its off im baffled !!! Quote Link to comment Share on other sites More sharing options...
Alex Posted March 7, 2006 Share Posted March 7, 2006 When you say dies do you mean cuts out completely...or it violently stops accelerating? Quote Link to comment Share on other sites More sharing options...
Guest jaybe1 Posted March 7, 2006 Share Posted March 7, 2006 violently stops accelerating. Thats why i was thinking fuel cut Quote Link to comment Share on other sites More sharing options...
Jurgen-Jm-Imports Posted March 7, 2006 Share Posted March 7, 2006 you hope it doesnt want to hit 1.75 bar lol Quote Link to comment Share on other sites More sharing options...
Guest jaybe1 Posted March 7, 2006 Share Posted March 7, 2006 Well it'll be a spectacular end if it does hit 1.75. Imagine the power just before the bang !!! Quote Link to comment Share on other sites More sharing options...
AJI Posted March 7, 2006 Share Posted March 7, 2006 sounds like fuel cut. 1.75 bar is enough to send your turbos through the bonnet 1.2bar is generally considered a max safe level. Quote Link to comment Share on other sites More sharing options...
michel lane Posted March 7, 2006 Share Posted March 7, 2006 1.75 !!haaaaaaaaaaa no wonder you got problems it must be going to 1.4bar ...... Quote Link to comment Share on other sites More sharing options...
Guest jaybe1 Posted March 7, 2006 Share Posted March 7, 2006 I obviously haven't tried 1.75 thats just what the high setting is set to. Dont know how to reset the boost controller though Quote Link to comment Share on other sites More sharing options...
Angarak Posted March 7, 2006 Share Posted March 7, 2006 Im sure I've read on this forum that running higher-than-stock boost with both cats in place will put the stock tubbies under more 'strain' (possibly not good for their longevity). Might be an idea to turn the boost down to stock level until you decat it. Quote Link to comment Share on other sites More sharing options...
Guest jaybe1 Posted March 7, 2006 Share Posted March 7, 2006 Mite have to take out the boost controller cause it still seems to be boosting higher even when turned off. Maybe its still getting a signal from it. Is this possible ? Quote Link to comment Share on other sites More sharing options...
Lucifer Posted March 7, 2006 Share Posted March 7, 2006 By any chance its not a silver manual on is it? With a bucket drivers seat? Quote Link to comment Share on other sites More sharing options...
