Anyway, I'm getting a P0125 code which is "excessive time to enter closed loop fuel control". The car is running great, fuel trims are +/- 2 and this code doesn't want to go away. The tps sensor has also been calibrated correctly after installing 65mm tb. The ONLY thing I think could possibly be causing this is the "whistle" possibly that I get from my 65mm tb or maybe my Tial 50mm BOV. Everything seems to be running great so I don't know why it keeps coming up......

 

search ecu flash, po125... i was throwing the same code, the local guy that tuned my car evo8dad on the forum, made several posts about it

 

you sure thats the description of that code? google says:

A code P0125 may mean that one or more of the following has happened:

Insufficient warm up time
Low engine coolant level
Leaking or stuck open thermostat
Faulty coolant temperature sensor

the description I gave is the one evoscan gives you.....

 

You don't happen to have the table "min coolant temp for closed loop" do you? If that is set too high, say over 30*, then you can get that fault. I would get that fault and if I lowered that table to 30, I was good.

 

The stock value is 7*
