This is a 5.3 with a big turbo, 3 bar map, DBW throttle body, th400, e85 , return fuel setup
p59 ecm from a 6.0
silver blade throttle body
major warm start issues, it starts very healthy and dies after 2-3 seconds, cant even keep it alive with the gas. Cold start was ok unless we just got lucky?
Its a bit of a down and dirty setup, no o2 sensors just open loop .
I feel like im missing something just cant figure out what.
Once it does finally run after several tries or a rest it runs great and idles good
any suggestions would be highly appreciated
