Brodierx7 Posted March 26, 2013 Share Posted March 26, 2013 Hi folks just bought a 1996 supra manual running a gt4294r turbo. All is well, but think its overboosting. It was mapped for 95ron before I bought it as I can't get super unleaded here. So what would be a safe boost to be running? I was wondering if it could be because of the cold weather that its got boost creep but not sure? Any ideas? Cheers folks. Link to comment Share on other sites More sharing options...
mellonman Posted March 26, 2013 Share Posted March 26, 2013 Cold weatger does make more boost, how much over boost are we talking its nearly always a vac pip to the waste gate if its large over boost Link to comment Share on other sites More sharing options...
tony tt Posted March 26, 2013 Share Posted March 26, 2013 My boost creeps in cold weather it could just be that. Link to comment Share on other sites More sharing options...

Brodierx7 Posted March 26, 2013 Author Share Posted March 26, 2013 It's currently boosting 2 bar and that's as high as the gauge goes...... Think it could do with being turned down a bit. - - - Updated - - - It's currently boosting 2 bar and that's as high as the gauge goes...... Think it could do with being turned down a bit.

Pig Posted March 27, 2013 Share Posted March 27, 2013 What ecu are you running? And what was mapped to? I would suggest putting a boost cut limit in place. I have similar issues but have a cut at 1.7 Get a stronger wategate spring Link to comment Share on other sites More sharing options...
Brodierx7 Posted March 27, 2013 Author Share Posted March 27, 2013 Running a link ecu, not sure what it was mapped to. How do you put a boost limit in place? I have a blitz boost controller. Link to comment Share on other sites More sharing options...
Paul Whiffin Posted March 27, 2013 Share Posted March 27, 2013 Whoever mapped it should be able to tell you what boost it was mapped to? 2 bar sounds like a lot of boost for 95ron fuel though, I'd be very careful until you get this checked out properly.

Brodierx7 Posted March 31, 2013 Author Share Posted March 31, 2013 Looks like they can't help! So going to have to go for a remap somewhere else? Where in Scotland could I go? Link to comment Share on other sites More sharing options...
