Data Log Test

you logged too many parameters, and logged the wrong throttle position parameter... plus, most of your log, your rpms were low... you need to be at least at 1800 rpm....

these are the parameters you want to log:

Air Fuel Ratio (Equivalence Ratio) = Under FUEL menu

Long Term fuel trim bank 1 = under FUEL menu

Long Term Fuel Trim Bank 2 = under FUEL menu

Spark Advance = under IGNITION menu

Intake air Temp = under INTAKE menu

MAF Sensor Mass Air Flow = under INTAKE menu

Total Knock Spark Retard =under MISFIRE menu

Engine Speed (RPM) = under PERFORMANCE menu

Commanded Throttle position = under THROTTLE menu


AND... looks like something's up with your truck, because your fuel trims are at -23 and -25!!!! that's not right at all...

check for vacuum leaks somewhere man... something is wrong somewhere... no way your fuel trims should be pegged fully negative like that.

you only logged one of the long term fuel trim parameters.... you need to log both...

and, that one you logged, is still waaaay off... it's still at -22 to -24...

is the MAF sensor on correctly?? facing the correct direction??

[redfoxsa]

the MAF sensor on correct direction and i check the leak on Air Intake Tube i found a gap in between MAF and tube and i seal it .

i use the MagnaFlow CATBACK :
DESCRIPTION:
5 x 11 x 22 in. Muffler, 3 in. Tubing; 3.5 in. x 5.5 in. Oval Tip, SINGLE REAR SIDE EXIT

What other i have to check ?!

i am confuse >>?! the car i brand new its only run 2000 Miles .
every thing is stock except the CIA and CatBack Exhaust ....
