Stu_bnr32 Posted July 27, 2020 Report Share Posted July 27, 2020 Hi, Bought my ECU around 3 years ago now, mapped twice and has been perfect, although had a bit of an issue yesterday - drag racing. My car should be seeing 18psi boost, which it was the whole journey too the strip - about 90 miles, and the whole way back, but when racing the car almost felt like In limp mode. Was eventually seeing only 8 psi but almost sounded like it was down a cylinder. Is this common when trying to drive hard? Does it sound like something obvious? thanks for the help, Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 27, 2020 Report Share Posted July 27, 2020 Its really anyones guess without a log or some clues to work from. It could be anything from a misfire due to a lack of ignition energy, some sort of engine protection limiter set too close, some mechanical issue such as a sticking wastegate or boost leak, or even something like fuel surge due to the harder launch.
