To add logging data you will need to add "pids" to the tabble it is pretty easy once you get the hang of it,.

Open the scan program and click on “Displays”
Open “Table (Primary)”
This is the table you will add and remove PID from your scans....
Right click on a empty slot and “Insert”
Now there are a TON of pids to choose from but to add Maf freq. You will expand “PID List” Then “Engine” then expand “Air flow”, from that list you will want to double click on “Mass air flow {HZ}”
Now if you look at the bottom of the Pid list table you will see a column that tells you the Source: ECM Size: 2 Sensor: Mass air flow freq.
Now the size is referring to the number of bytes that Pid uses. Depending on you PCM you should have 24 or 48 byte max. keep in mind the more bytes you log the slower and less resolution you will have..

 

I am in Glen Burnie and yes I agree with the hands on practice. You won't learn it unless you do it. But I can not see spending the money on that product on to get soooo damn frustrated that I have someone else do it. I tell ya I have learned that over time some things are left best to the professionals.

 

Damn I love this forum. A great bunch of guys with a lot of helpful info. Thanks gang for all the input and it's off to the races. I'll work on the Maf tables today and try to post a file.

 

Sorry it took me so long guys. Besides being cold, the weather is finally clearing. Here are the log you asked for including maf.

Let me know your opinions.

 

It looks like you have some knock, i don't know if that's false or not. But it isn't tuned that great right now, possilbe since you have added some things, thermo might have something to do with it. Your fuel trims are way off, not running good at all. Get to the basics and start from there. Get your VE and MAF done, start in the tuning 101 thread on here and there are beginning threads on HPT forum. Your fuel trims if you have to tune with them should be between -3 and +3 or about that. I would get a Wide Band O2 since you are turbo'd, invest the money so you know exactly what your A/F is, with that turbo i wouldn't take the chance of tuning with NB02's.

 

Thanks gmforlife for looking, truck is running rough. I have a feeling that my plugs aren't in the best shape due to the fuel levels. Im sending the log to Allen today to get him to retune. I changed the fan seetings the other night to accomadate the 160* thermo.

 

Cough, Cough.......piston. You might want to do a compression test.

 

haha hope not.

 

You got to be kidding me, that would suck. The truck only has 18K on it.

 

So what is the latest? Did you get it retuned yet? Do you have any logs with all the MAF data that are longer logs?
