I'm curious about the SOHC engine running off the DOHC ECU myself
The original reason this question popped into my head was after reading about SOHC engine owners using S-AFCs to lean out their A/F mixtures at higher rpms. Could this be an aspect of the "less than stellar" performance of the MAP-based ecu? I remember somebody posting dyno runs of pre- and post- S-AFC tuning and he gained something like 7-8hp!! This would place the SOHC engine in similar territory as the DOHC engine WRT hp numbers above 5000rpm.
Anybody know how much a AWD dyno session at that shop in Gaithersburg, MD is? I know, it wouldn't be a TRUE comparison considering differences in dynos, etc . . . but it would give a better understanding as to whether the ecu is to blame for those high rpm power losses with the SOHC engine.
