SES LIGHT set these codes: (a few times <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
p0171 left bank sensor lean
p0174 right bank sensor lean

i cant figure out how to richen up via ls1 edit. can someone school me on it <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> as i will need to learn so i can richen it up more for nitrous runs <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

ALSO on my shift points i was hitting rev limiter. 1-2 i have at 25 mph
2-3 is a 65mph
i have a st3500 and 3.73's
im assuming i just keep lowering the mph to get the correct shift but geez ive already lowered quite a bit....

thanks for any help guys and let me know if you need more info

o yea, rev limiter is 6200 and resum at 6199 in all gears if this makes a dif

Black LS1 T/A

If you have a stall converter, 6200 is just WAY too low for it.

Move it to at LEAST 6600.

Go ahead... it won't hurt. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Just try it. Get tht ceiling out of the way. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

When I had my HPP+ programming in, I set it at 6600. With the Procharger in place, it peaked so quickly, I eventually bumped it on up to 6800. I found that even though I saw only 6300 to 6400 on the tach, it sometimes hit 66 and even 6700 RPMs.

Just get the rev limiter out of the way and be done with it. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

yea but i still got stock valvetrain...no way in hell am i risking 6600 rpms's....

If your MAF is massively ported and you are maxing out at 25% l-trims then rescaling the MAF table by an appropriate amount will fix your problem (l/r bank lean codes).

Otherwise this code indicated a dead o2 or a leak before/around the O2 sensor in the exhaust stream, and is not something you should attempt to program around (and something you can not program around, other than going open loop)

Jerry,

Are the shift point / TCC tables you're working with stock? If they're still stock you can simply scale everything by OldGear/NewGear (presumably a number less than 1.0), lowering all the values accordingly. Same goes for WOT values. You can then make further adjustments as needed for the converter. If this is for an F-body, have you already scaled for your gears using the gear scaling feature? (It should do the above for you in one fell swoop.) Or maybe I'm misunderstanding the adjustments you're trying to make...

Don't mess with your shift points until you solve why you are running so lean. That could be effecting your shift points. Your shift points are so low that it raises concerns about your tranny. Hopefully they will go up once your lean situation is resolved. Otherwise, a shift kit or tranny rebuild are in your future. <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />

well i just monitored l term fuel b1 and b2 at idle (bad weather) and this is what i got...
the entire 10 minutes it was at 25 on both!! did i do somethin wrong? also at idle which i dont know if it helps i got ign timing of 18, tps was .4%, and b1s1 was .85 and falling to like .1 as it got warm and b1s2 was at .895 and falling to .1 fuel trim cell was at 20.

o yea i did just do the gr and air mods by blocking off the plates if that makes a difference.

Are your ltrims that high driving around too?

Make sure there is no air leak in your bellows and that they are fully connected to the TB. Are your TB screws tight to the manifold?

Just saw you messed with your EGR. Double check that everything is sealed up tight.

put stock programming back in and bumped the high octane spark to 130 % (was suggested so i tried it) still got 25% on both l trims at IDLE and 24.2% with a little gas. NEED HELP <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />

I would try posting in external engine looking for help.

provide info on everything you have done,
SES codes,
when you first discovered you were lean,
and list all your mods

Borrow a stock MAF and see if that helps.

i got a couple more things to try, thx for your help!

also couldit possibly be BAD GAS?

BlackhawkSS

iTrader: (3)

OK <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

what i did was reload the stock file for my pcm and reset it and then multiplied the high octane spark table by 130% and this got my O2's .89 on both and my ltrims at 0 all at WOT (100% TPS). and no KR <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

BUT <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" />

also at WOT my timing advance was like 35 to 37 degrees <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />

any suggestions on that? now i just gotta work on my shift points again when the weather clears.

thx for the help for those who did.

I'm not saying that it doesn't work for you, but 63 mph is really low. If there were no converter slip or lag time that would be shifting at roughly 5000 rpm.

ToplessTexan

I hear ya. Believe me, I came down to 63 from above. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> Still trying to figure out how much slip I've got but am AutoTap limited. <img border="0" title="" alt="[Sad]" src="gr_sad.gif" /> Plus, testing attracts way too much unwanted attention...

might be time for a shift kit or a very modest bump in line pressure at WOT.

well im getting close <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

does it matter if ltrims go to like -11.7 was my max when cruising but remain at 0% WOT?

when running nitrous where do i want my b1s1 and b2s1's at?

no more timing issues <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

but have shift issues <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" />
