Tuner Studio datalogs incorrect values
Posted: Tue May 16, 2017 10:06 pm
Hello All,
I'm assisting a friend with an odd issue he is having with MS2 extra.
His Tuner Studio gauges (RPM and Boost) match his instrument cluster RPM and mechanical boost gauge. However the recorded logs from Tuner Studio are showing just about 1/2 the actual RPM (7k --> 4k) and Boost pressure (~20psi --> 7.4psi).
Attached is a snippet of the log at a known problem location and the current tune he is using.
Note during after 120kPA his AFRs go dangerously lean.
Thanks!
