You don’t know what 14.7:1 is???

You might want to read the manual 10 times and every thread you can find before attempting to start the engine. I couldn’t fathom how hard it would be trying to tune an engine without a Wideband sensor!! Is your ecu even configured for a 420a?? If you got it from Diyautotune, chances are it’s not configured for a 420a unless you asked matt or someone for that option witch adds extra bones. To help everyone out including your self you need Megalogviewer to view what ms is doing. While your there check out Tunerstudio.

As adamzty said, if you cant even see a rpm while cranking (around 250) then stop trying and go back to the manual and your wiring problems.
