Wow after changing so much parts my car is finnally not bucking or hesitate,it also got a real decent idle and drove really well

Right now im at LT BLM: 138 AND 143 wich is 8% and 11% of add fuel by the pcm since its seems that my tune is a little lean.I dont have any leaks(spray a full can of ether all around the block,intake,tb,vaccum line ect).

So how do i add a little fuel to be more in the 128 lt blm range?

Thanks

Not sure of all the details you are experiencing but search for "MAF Calibration" and you will find all you need to get your BLM's correct.

Before you do that, make sure and determine any exhaust leaks prior to the sensors.

 

Are you lean across the board or at specific RPM/MAP ranges.. If it's at all ranges and you are sure of no air leaks and your O2's are telling the truth then you could tweak the injector constants to add a bit more fuel. Borrowing a wideband would verify your actual mixture.

 

I'd make sure your injector constant is dialed in under normal cruising conditions. Adjust until your BLM's are pretty neutral. If this throws fueling off at idle or other areas then maybe adjust the MAF at those areas to level it out.

 

Ok its time for me to look like a stupid moron

I ve make everything myself on this car and the only thing that im totally lost is the tuning.Here where i live there is no real shop that tune ltx so i need to do it myself...

So if someone can just give me the basic and what to do to procede correctly.

-My O2 sensors ares 50 miles old(brand new) and my plugs also.
-I spray a full can of ether all around so its seems that i got no leak.

I look at th maf table and i dont know what to do?

Also i look in the constant table and my injectors are at 31.61(racetronix 32lbs)

I ve reflash my pcm to be sure and then i ve made 3 logs:

idle: 136 -142 steady with very little change in the ST
1st to 4th normal: 130-128 kinda steady except when letting off the gas to change gear.
3rd gear steady: 140-132 steady and the ST move a lot

Got the log saved if someone wanna see.

Thanks for your help

PM me your email and I will send you my excel spreadsheet I use to calibrate my MAF...if you want to go this route. This is what I do to get my BLM's in the 128 range across the board.

 

You got Pm

And by the way even with the risk of sounding stupid(again) i truly dont know wich route i need to go but i truly know that a good tune is in the 128 blm range. So if i need to play for hours and hours in tunercats with maf table or other ,i will do it.

Thanks
