hodge Posted July 21, 2008 Share Posted July 21, 2008 My EGT is fitted pre turbo in the manifold pot 6 to be precise (as recomended by CW). My question is on slow progresive speed increase im hotting 950 degrees at full boost but if i floor the car its only hitting 850 degrees on full boost at 1.2 bar. Does anyone know any reason why this would happen. Thanks in advance. Link to comment Share on other sites More sharing options...
Ark Posted July 21, 2008 Share Posted July 21, 2008 Probably something to do with heat build up over a longer time. Mine does this too. Link to comment Share on other sites More sharing options...

hodge Posted July 22, 2008 Author Share Posted July 22, 2008 I don't have an air fuel ratio gauge fitted chris. Is this anything to be concerned about. Link to comment Share on other sites More sharing options...

David Reid Posted July 24, 2008 Share Posted July 24, 2008 The only mechanisms to control EGT is ignition advance and fuelling. Advancing the ignition shouldnt be an option as your tuner should have aready optomised it at peak torque or the det limit. I suspect he has mapped the lighter loads to a lambda of 14.7 to give you good fuel ecomony. You have just found an area where this results in high EGT. If it were my car I would take it back to the tuner and ask them to remap the area with high EGTs. Link to comment Share on other sites More sharing options...
bolarbag Posted July 24, 2008 Share Posted July 24, 2008 Yeah as above, its hard to find a good level of economy, performance and safety The mapper's probably thinking he's done you well there, but 950 is too high, you want to stay around the 850C area Link to comment Share on other sites More sharing options...
