Problem with my Head/Cam 98 LS1 camaro - files attached

[WeathermanShawn]

Josh, something seems amiss with your LTFT's. In some places adding +23% to your MAF did nothing..

Well try the following:

1. Make B0120 400 RPM instead of 4000.
2. Drop SAE.SPARKADV Pid.
3. Drop SAE.VSS Pid
3. Add GM.HO2S11 and GM.HOS21 Pids
4. Add GM.IBPW1 Pids.

You should still be at 24 channels or less.

Whenever you are adding that much Airflow to the MAF, normally you see a 1:1 increase in Trim change. +23% = a 23% drop in LTFT's. So, if you do not see that you always worry about 4 things.

1. NB O2 sensors are not switching properly.
2. You're injector flow is not supporting your Mods.
3. Big-time exhaust leak..usually this is the culprit.
4. MAF needs cleaning (are you de-screened..is this a stock MAF?)

Re-set your Trims again..if you really had done this you should have started out at (0) on your Trims. Looks like you were still at +25% when your log started...

Sorry for the hassle, but these changes are necessary..

[WeathermanShawn]

Josh, also reset your trims using the following:

With key on (ignition)..

Calibration >> Long term Fuel Cells>> Reset both banks. The Table should now read all zeros. So, when you start logging the LTFT's should not already have a value.

I'm thinking yours did not re-set..you seemed to get richer during the log as your LTFT's learned..

I made the change to B0120 and set it from 4000 to 400.

Droped SAE.SPARKADV Pid and SAE.VSS Pid

Already had GM.HO2S11 so I added GM.HOS21 and GM.IBPW1 Pids. I now have 19 PIDS Selected.

MAF is stock but descreened.
Also have stock injectors.]
Also make sure the fuel trims are cleared using both methods before I get logs tomorrow with the new PIDS.

I will clean the MAF in the morning and check everything for exhaust leaks. Also will put in my new bosch 02 sensor for my innovate wideband and get some logs from it to compare. Once the LC1 > Scanv2 serial comes In I can integrate that.

[WeathermanShawn]

To evaluate your CALC.VET Tune & Log, we need to see EXACTLY the Pids as indicated in the following screen-shot.

Total 23 channels. No substitutions please..

[blackflag]

I have 23 PIDS selected. My tuning laptop is small so I could not fit them all in one screen. So I attached them in two images.

Its nice out today, so I'm going to go clear the fuel trims and get another log. Everytime I reset the fuel trims it doesnt want to idle until it gets a little heat in the motor.

[blackflag]

I went back and double checked, and I still had the first set of PIDS selected. So I removed VSS, Cyl1 Timing as mentioned earlier.

Also selected
Heated 02 Sensor Voltage Bank 1- Sensor 1
Heated 02 Sensor Voltage Bank 1- Sensor 2
Injector Base Pulse Width Bank 1

However, the three of those have red X's on them. I'm going out to the car to see if I can validate them???

[joecar]

See at bottom of PIDs tab it says Selected Channels... you can go up to 24 (don't exceed 24, otherwise the frame rate slows down).

[blackflag]

Just attached Flashscan to the car and it validated all the PIDS we needed. I now have 24 selected.

Also uploaded new tune with B0120 400 RPM instead of 4000.

Going to clear the fuel trims and get some more logs.

[blackflag]

Reset fuel trims and they al are at 0%. Going to let the car warm up and go log now.

[blackflag]

Just got back making a new log w/ the updated PIDS and made sure fuel trims were reset.

How does this look now?
