finally did some logging, need help..

[badls1]

hey, i went out an did a little logging yesterday. im pretty sure i have i right pids this time so it should be good. what do you guys think? i need some help on what to change.
thanks-curt

heres the tune and the log i did

Hello there:

Just did a quick scan, so forgive me if I missed any bigger details.

Overall, not bad..I take it most of your tune is stock. A couple of things stood out:

1. Generally positive LTFTS.
2. Some KR..though the stock tune is woefully low on the amount of High-Octane Spark for WOT.
3. Fuel injectors are getting close to maxing out..91%..not too bad, but not a lot of margin.
4. I am not sure what is going on with your narrowband O2 sensors. Your average is very lean (275-290), and during PE mode it looks like they go to near zero? How old are they?

Thats just a very quick synopsis. You have the normal things like disabling COT B0701, to maximizing the PE AFR B3618. I would find a better Spark Table B5913..perhaps from a 1998..

In all honesty it would take pages to say where to begin, but thats a very quick synopsis from this end. It does not look too bad..but something about the narrowbands look wrong?

Perhaps some other readers will comment.

Good luck..

I would like to see the SAE.MAP intake manifold absolute pressure pid logged, not the map sensor voltage pid before I come to any conclusions.

what do you mean by a 1998 spark table? should i copy and paste the table from a '98 into my tune? one oxygen sensor went bad and i replaced it a little while back, the other could be going too.
5.7ute-my next log ill be sure to record the SAE.MAP intake manifold absolute pressure.
btw- what kind of logging do you guys like to see? dogging it in 5 gear? wide open runs?
thanks

can i turn my ltft's off?

No, it was just a suggestion. The 2001 (IMO) has a very conservative spark table.

You can turn your LTFTS 'off', but that is not really pertinent. I would model airflow, spark, and fueling in a very systematic way. You have to first decide what kind of tune you want.

Best to tune in your dyno gear..I use primarily 3rd and 4th (M6). I do WOT where I can safely do it.

F.Y.I., there are some great Tutorials on how to get started on the EFILive website.

Good luck..

I like to see the car driven as you would normally, with a few WOT runs at first. This will give you the solid base to work from. Once those areas are sorted you can then start working on the not so commonly hit cells.
You can leave the fuel trims on. They should reset every time you flash in a change to the tune.

Hi badls1/Curt,

Log SAE.MAP (kPa) instead of GM.MAP (V) as 5.7ute/Mick said above.

Looks like both front NBO2's stopped functioning (resulting in DTC P1133 and P1153 being Current)...

The first part of your log shows the front O2 voltages switching too slowly (0.7+ seconds/cycle)... and then they pretty much stop switching and PCM goes into Open Loop (and trims go to zero)... you'll have to find out what's wrong (how many miles on the O2's...?)

Also your MAF may soon throw a DTC, the scantool shows P0101 as Pending.

What mods you have...? Is the MS4 cam in this car...?

Edit: I see your sig now, I don't remember if I saw it before...

[badls1]

im going to do some logging tomorrow and ill make sure i change that pid. one oxygen senor is almost new, the other one ive never changed, ill check them out tomorrow. any way to test an oxygen sensor? im not sure on the MAF, i did have it disconnected when i working on the car, could the code be from then? i have the ms4 along with the mods in my sig.
thanks

did some more logging today. i switched out my o2 sensors but i still think the bank 2 one is messed up. not sure why the maf sensor performance is showing up some of the time as a DTC or the TPS sensor.

heres the logs and the tune
