Hi, My last MAF went bad so I put my stock one back in and copied the factory chart back into the MAF section. (The Granatelli I took out was tuned over email) What's a good baseline starting point...

You can see in the log at 1:28 The TPS shows .4% with foot off the gas pedal.

Looking for some starting points for my 2000 Trans Am Manual 6 Speed. The Car is Bone Stock except for SLP Lid. What are some of the most basic "cookie cutter " changes I can make right off the bat...

I Just Installed brand new Denso O2 sensors from NAPA. Car seems pretty good. Log looks like they are oscillating. Please take a look and tell me what you see.
Thank You Guys for all the great...

Now i got P1134 and P1154 codes?!

attached are a few logs. One is right after the deletes were made and One was when the new codes popped up.

The logs i put up here originally are after i just cleaned my MAF with MAF spray ( descreened ) and i also had just cleaned out my throttle body and IAC which was gunky.

Here is my tune with...

Ok Folks, here are some details that you should know
- I do have Kooks Long Tubes, No Cats, No leaks at Manifolds- i have had them for about 2 years now without these nuisance codes
- My Header...

Thank You for the great info!

I realized recently that this all started soon after i also sealed my leaking collectors with High Temp Red RTV. It was not sensor safe. Could it be that cut and dry?...

Im trying to get help for the same thing on here! Only mine surges at idle. You should track your voltage on your logs since some issues can be voltage related. Good Luck!
i wish i could be of...

Please look at these runs from just now. Why are my O2 sensors not zig zagging uniformly like they used to? Is that the indication of the "insufficient" switching since the reading doesn't change...

Hey Guys,
I Replaced my dying battery and Alternator to fix some voltage issues but am still surging only after it throws the codes
P0133
P1133
P1153
After idling for a while it will...

Please Help

Currently:
- AC Delco Alternator just changed this morning ( attempt to fix Voltage drops after driving for a while):doh:
- repaired/ soldered Gen L terminal wire ( stopped that code...

So its probably a good idea to leave those tables alone (Max Knock Retard)
and just zero out the (Burst Knock "Enable Cyl Air, and vs RPM)
right?
Then you eliminate the calculated knock but keep...

Hi Guys
Can someone please help me read this scan.

At WOT- do the low numbers on the O2's mean I'm lean

I tried a VE and Timing table that look pretty aggressive.

Can someone please check...

also noticed that Tank has an aftermarket cam in an 06 5.3 Silverado.
Mine is a 5.7L LS1 in a 99 Trans Am with bolt ons but cam is stock

I copied and pasted these onto my tune (saved original)
Before I put this in the car can you see if i did it right.
Also here is what I also recently changed
- DFCO to 284
- Enabled STFT
- Min...

For Me and all the Dummies

1- What are some reliable Wide Band Kits and how much $$

2- Do Most guys use a Stand alone AF meter that stays in the car or do you upgrade to the HPT Pro and that...

The cam is stock. Just bolt ons. My mass air and TB are all stock.
I have the Granatelli Mass air but i got lean codes at the track so i took it off for now.
The Timing table is what i copied from...

I drove some more last night. I definitely notice that i am planted in my seat more.
I am going to throw this last tune up on a new thread and let some of the boys put in their two cents. I...

Well the car feels pretty good. pulls hard through the gears. Not sure how much better but it does drive good.
I smoothed out the VE table by highlighting the blocks that I added 10 to and the...

Here we go
I made the changes.

Started scan with a cold start and drove for a while. gave it some mid throttle pulls but nothing crazy. lots of regular driving.

Thanks!!

I made the changes. The car drove fine. I got the scan and then flashed my old tune back in.
Lets see what you think about it.

Its 35 outside but the heat soak makes the IAT read in the 70's.

I compared the stock file to the original hypertech one and the only changes were to the timing and to the PE fuel multiplier.
I also went to the repository and double checked my stock tune against...

i set the DFCO TEMP to 284. The previous number was -22.

Chart shows the O2's working together but I don't know what I'm looking for.

Also no KR

I haven't smoothed out the graph yet.
