Pav Posted February 13, 2009 Share Posted February 13, 2009 Hey guys I have a bit of a technical question that few may be able to answer precisely and correctly.Firstly, what is the exact level of boost (in psi or bar) that the fuel cut limiter comes in on the stock ep91 ecu?Secondly, what is the exact maximum boost that the stock ecu will fuel to? I have read previously that its 13.9 psi. Please someone with in depth knowledge on this, can you let me know.A lot of people seem to think boost cut comes in a 0.85 bar from what I've read. This does not appear to be the case at all after some peak hold boost monitoring on my avcr when on my way home from work tonight. Any help would be much appreciated Cheers,Alex Quote Link to post Share on other sites
WallaceGlanza Posted February 13, 2009 Share Posted February 13, 2009 Its not measured by the boost its when the map sensor reads 4.1v which is generally around 12.5 psi but it can vary slightly between cars. Quote Link to post Share on other sites
