Need help with understanding MAF adjustments.

[5.7ute]

I am not using the long term fuel trim pids in my black box as my nova that I am tuning does not have narrow bands. Could I take them out of my options ini and replace them with manvac?

Another question, can you log wideband through serial cable in pass through mode yet?

Yes & Yes. You need to do a manual validation of the serial pids when connected though.

ok I think I got it right in my options. I replaced the eops with cylair , Longterm 1 wiht dynair and also longterm 2 with manvac.

How do I go about manually validateing serial pids ? Just select pids and plug into car to validate?

Connect to car,
select pids,
save pid selection to file (for future reference),
File->Connect,
Info->Validate PIDs.

I will do that tomorrow Joe, Thanks. You guy's have been lots of help, I have learned a lot the last few days.

I will post results of how the nova runs tomorrow night if i can get the tune done in a few passes. Hope to be close enough to run the bracket race tomorrow night.

Races were cancelled after I made the 90 mile trip. The freeze busted the tracks water mains. I will try again later.

Went to the track yesterday. car was pulling timing again but I figured that out. Tq management in the transmission even though I dont have a 4l60 in it, (th350) was pulling timing. I also dont have a vss so the car did not know it was moving . I turned everything that I could find off that could pull timing and that fixxed it. with tq mng. I ran 12.06 @ 110 mph.

After fixxing the timing issue It went 11.24 @ 119.5mph with a 1.62 60 ft. Not spinning, the car is leaving like it has a 2 step. Intake air temp was at 115+ leaving the line and it was weak off the line. once I go wot it leaves soft and Then breaths a good gulp of air in and its like nitrous hits it. air fuel on that pass was around 12.0/1
next pass was a 11.12 @ 119.8 with a 1.59 60 ft leaned it out to 12.3/1
After that pass I pulled it back to about 12.6 but have not read the data logg on these yet. It reacted to nice with a 11.05 @ 120.2 and a 1.54 60 ft. (still have that 2step going on) and I was so wanting that 10 anything that I went back around without changeing anything. Car had a long break to cool off since a friend of mine smashed his oil pan ,the track crew spent an hour cleaning up.

After the cool down(not sure yet on iat yet) my car left with a 1.57 60 ft(still hesitateing) and ran 10.96 @ 120.69 mph.

I am moving my Iat sensor and my filter all the way out by the grill to get the hot header air away from going into the engine. That should fix that 2 step feeling and ram some air in at the same time.

Joe they are on my laptop and I need a new charger for it. I broke the wires to my charger last night.

I have to reroute my cold air intake to the grill. Its breathing some hot air in but i do believe there is something else going on with it. That bog off the line is on every pass and then it comes alive.

Here is a video a friend took though of the 11.05 pass
