I got 174/143 with just stage one 1.59 and k&n filter

Good numbers.

Can someone check mine out. Just picked up a code P0456. Double checked gas cap and it was on tight. Cleared code and drove it around...nothing yet.

Stock car e85. 200ish miles ago switched over to V2.06 tune.

Thanks!!!

If the OP were to mix in a few gallons of 91 (for whatever reason), his AFR under boost would get much richer. But after some brief learning, LTFT would go several deg negative and he would be back to the AFR he sees now.

1. If i drive in close loop how much time needed for ecu learning ?

2. after flashing to stock map LTFT at wot is 10% even after 120 miles.
is it mean stock ecu default is 10% LTFT or the problem come from o2 sensor or come from low ecu learning time?

It only takes a couple of minutes driving in closed loop to set the fuel trims, however the higher flow rates (rpm) areas you dont do much driving in closed loop. So if you deliberatly do some steady throttle say 25% throttle runs from 2000 to 5500 or so it sets the fuel trims quite fast.

Default ltft after flash is 0%.

max ltft is about 30% but anthijng over about 10% is undesirable to much fueling error may cause hesitation bogging lack of smoothness.

shivs tunes good for about E60 to E90 at arround E70 to 75 your ltft will be only a few percent at the outer ranges of the tune capabilities you will see ltft aproaching 10%.

Thanks
it sounds the my front o2 sensor should replace.
last nigh i opened oft stage 2 e85 map with ecutek .
it seems we can flash oft ots maps by ecutek.
