lwells Posted January 19, 2006 Share Posted January 19, 2006 Rich and retard maybe? I forget what the GT-R's threshold is. Have you checked the ECU for fault codes?

warriorbrawl Posted January 20, 2006 Share Posted January 20, 2006 yeah your ecu could be going into safe mode if there is a problem somewhere eg fuel pump stuffed. Or is your intake pipes going soft and sucking shut causing a big restriction Link to comment https://www.sau.com.au/forums/topic/102476-r32-gtr-loss-of-boost/#findComment-1883258 Share on other sites More sharing options...

rev210 Posted January 20, 2006 Share Posted January 20, 2006 you have a heat related leak (both of you). As the heat increases the rubber softens and allows some air to leak out. Sad to say but put a scewdriver to each and every one of your hose clamps might fix it Link to comment https://www.sau.com.au/forums/topic/102476-r32-gtr-loss-of-boost/#findComment-1885587 Share on other sites More sharing options...
Sico04 Posted January 20, 2006 Author Share Posted January 20, 2006 heat related leak?? if this is so what is actually happening, does the computer relise whats going on and change settings?? cause some times i could be driving for 2 hours and it wont happen on a pretty warm day other times i could do less then 30 min of driving and why would simply restarting the car stop whats happening??

AMS Posted January 21, 2006 Share Posted January 21, 2006 Had the same problem in my Stag....never found out what it was untill I blew the turbo Link to comment https://www.sau.com.au/forums/topic/102476-r32-gtr-loss-of-boost/#findComment-1886765 Share on other sites More sharing options...
rev210 Posted January 21, 2006 Share Posted January 21, 2006 when things leak they usually do so almost randomly. If you haven't tried to check the tension on ALL of the intercooler pipes then I suggest you do so, if not only because you should do this on a regular basis as part of maintenence.

Robbo Posted January 22, 2006 Share Posted January 22, 2006 After a while when they heat up the car pings/predetonates which sends the ecu to the knock map, until it is restarted. Unfortunatly the solution is better fuel, less ignition timing, or less boost.

lwells Posted January 22, 2006 Share Posted January 22, 2006 will solve the problem if i put after martket ecu in??coz im car will be getting on monday?? <{POST_SNAPBACK}> Yes, until you munch the pistons (unless you retune). Again, check for ECU error codes. If its going in to limp home (rich and retard) mode, its a pretty good indicator of detonation which will lunch your engine. Don't just stick a new part in without first working out what the problem is.

Sico04 Posted January 23, 2006 Author Share Posted January 23, 2006 just called ice and they have suggested that it could be the afm's or coil pack possibly breaking down on hotter days..........or when things heat up Link to comment https://www.sau.com.au/forums/topic/102476-r32-gtr-loss-of-boost/#findComment-1889453 Share on other sites More sharing options...
