Hi,

I've made a bunch of changes to my car as I am in the process of converting it for drag race only duty. I've been having a hard time getting the ECU to drop into closed loop. I went into the engine diagnostics tab and changed a bunch of systems to "no error reported".

the list of things that are different:
ABS eliminated
Brake booster eliminated (manual brakes)
EVAP system eliminated
factory fuel tank and level senders are gone (fuel cell in the trunk)
return type fuel system installed along with external regulator set to 39psi (all cells in the fuel pump voltage table set to 15v)
Inline pump is being fed from the factory fuel pump source currently
Aftermarket wheels without TPMS sensors
running E85 now but the only tune change I've made so far is changing the target AFR


I get check brake system, TPMS and an error about the DTE and fuel level whenever I turn the key on but I don't think they are playing a part in preventing closed loop.
