8psi with a 3.2 normal???

the scan is what we need to see and its messed up.

You might want to start with a new stock bin and start over.

Sometimes the file becomes too tampered with that it becomes difficult to work with.

Narrowbands are not very accurate at all WOT. But to be reading 880MV(lean) and your AFR on the wideband peging 10.0 It seems off? Typically you want 930MV..

880 is lean??:confused: i thought that it was rich? unless are you talking about that the computer would correct that with a "lean pulse" to average 450...or are you saying thats a lean "rich":th_sick1:
 
alright ill go get it warmed up and do a idle scan with a WOT run then ill go with a stock bin and cross my fingers on that oh dear... :th_nervous:
 
dont actually RUN the car with the stock bin without correcting for all the mods.....

Namely injectors.

Then get the fuel okay at 10% TPS and less and idle.

Then try 0 psi, get that down then 2-3 PSI, get that down, then more till you reach 8 psi.

Also limit it to 14 * of timing when doing the testing.

880 WOT is considered lean in narrow band terms. YES

Scan Idle air counts. and post it up to see if you have a vac leak. I wouldnt start from a new stock bin. I dont think you have the knowlege to do so. No offense ment.

none taken i am comfortable with saying i am "retarted" (oh yes pun inteded) *slaps thigh :th_laugh-lol3:* when it comes to the tuning side of things. so beings i don't have a vac leak how would i go about with the diagnostic aspect of troubleshooting? my trouble shooting strengths when it comes to cars is specs on sensors and dtc's and doest look like that is going to help me here....
 
but thats where my wide band is... so i need to replace my rear o2 with that fouler thing and add anouther bung for my wide band?
 
I know this looks horrible but i noticed that some of these timeing tables like start dropping off at 5200 rpm but if my shift tables are now modified to 6200 should i continue to keep the numbers high or is there a reason beyond my understanding why it would drop off?

this one is my "Max Torque timeing vs. rpm vs. cyl air" table

hey well i will do some scans tonight. the "tune" i have is a prj tune and all i changed was the injector size and the shift tables and the fans... i haven't studied enough on how to do a proper spark/fueling tune... i did the install of the parts got it running and drove it back to San Diego from Washington state and just haven't had the time to read on the "major" dial in.. i know its a little lazy but any one know the link some one had running around here for "tapping in" the egr harness to get the wideband to register on vcm scanner? just for temporary for tuning purposes

I find it hard to believe that Paul would have your AFR @10. He tuned my GTP and it is running at 11.5 ish AFR. When I took it to him we spent pretty much all day tuning because I have KR issues. Why don't you let him know what your AFR is at. I would bet he will fix it for nothing or next to nothing. Also, what is your commaned AFR at. Maybe its because you don't have the 42.5s dialed in correctly yet?

the cat test is difficult to delete.

Thats the issue.

I dont know how you did it but i'd like to know.

The Tiny Tuner

if you download the newest updates(tiny tuner update and database update) not the "public release" and have a .bin under dignostics it has the cat dianostics in there guess just put the peramaters WAY outside of anything your car would see and it would never do the test... just thinking logicly... hope that helps out some! sorry guys i got to get to bed :th_yawning: i have to be at work at 4am HUGE THANKS on this entire fiddling

i could but i really dont want to bug him too much.. but also i want to use this time as a learning process. his tune he did was for when all i had was sd headders and fwi. so he didnt have much to go on.. i in no way want this process to look bad on him in any way he deffantly knows his stuff and the car ran AWSOME with what was done to it at the time.. but with increase in mods = changes in tune that he didn't know about and put in and i am trying to understand what needs to be done and what the different changes do to make the car run differently.. does that make sence? to me it make's more sence to ask questions on here with people that like to help on their own time and not under pressure to "just get the job done"... the wiki is great as well as other "tuneing tutorals" but the "debated do's and don'ts" and the "extra eyes and thoughts" make a better understanding and a higher quality end result...

sorry i am so tired my mind is getting foggy where do i find the commanded a/f ratio? that in a scan or a vcm table?

It should be in a scan. Also, I think its cool that you are using this time as a learning process. Actually doing it and not just reading about it, is to me, the best way to learn how to do anything, especially tuning!
