I just did a first start on my standalone GM 1.4 turbo engine. It has stock internals, GT2056 turbo, 60 lbs injectors, Flex fuel sensor, E85+ mix. (87 by hand tester, 90 by FF sensor)
It started, ran for few minutes, temp showed 150 on scan, stabbed throttle couple times, shut it off.
I will hook up wideband tomorrow, and if it isn't raining, I'll run it for a longer time.
