i just installed sd headers, yella terra 1.84 full roller rockers, and a LQ4 maf with a 4" fenderwell intake on my 04 comp g. I still have the stock 3.8" pulley. I imported the lq4 maf table from zzp and went to scan. the cruise scan has no kr.

the question I have is with the WOT scan. im seeing kr and my wideband is at 13.5 the entire pull, im just wondering how I go about richening it up? any help would be awesome

I don't yet know how to attach tune files or scans. so I can email them to u f u want to see them, or if someone can tell me how to do that as well it would be appreciated.

sorry im new to the tuning scene, but I work as a mechanic daily so I know the just of what everything does. not my first modified car just my first tuning experience
 


I would find out if you really need that LQ4 maf, and if not put the stock one back on. are you using dhp or hp tuner?
 
Why did you upgrade maf sensors??

Are you going to outflow the stock maf sensor??

Most people on 3.25's to 3.4 can't outflow the maf anyway.

And you add to the MAF table to increase fuel. You add by %, so from where you need more fuel, figure from 7,000hz you could add 3% more to the table.
 
Scottydoggs do u have a link to Eddie table modifier.

Sgt marshal I'm using dhp

Fivefingerdeathpunch I upgraded because it fit nicely into my 4" intake. I didn't want the bottle neck and I will need it eventually so I would like to get used to it

Far enough, but in reality the throttle body is always going to be smaller than your intake size and you can never upgrade your throttle body.
 


I'm not going to say never seeing that u can get up to 100mm drive by wire throttle bodies. Just have to make an adapter plate. Not that I would but I don't say never
 
The stock pcm for a 3800 can't be tuned for the upgrade though, they don't provide enough data/tables to allow for a change. A GM V8 pcm is far more advanced and has 10x the tables to allow for adjustment of throttle blade size.

Sorry to bring this off topic more, but thats the truth of it.
 
This is the message I get when I try and import it into my dhp tune file.

That's odd. I get the same message, but only when I try to import the VE table. You can look at the .CSV file and see what rows are not in it. In my VE export from TM the first two rows are not there. That's why dhp won't import the file.
 
I click on the CSV file and no data shows up just a whole bunch of empty cells. I import my bin file to table modifier so it automatically imports my new tables into my bin file and saves them. I'm trying it that way right now
