Just had a closer look and compared it to mine . It is only when you back off that you see a delay , not when you apply the throttle . I see a delay with mine as well when I back off although not as pronounced .

Don't worry about it - not a problem ....

 

check out my log below and you will see that on the gas is instant - backing off the afr takes some time to respond

 

I think it's the OEM throttle not closing quickly...you can see the PW lagging with the AFR

Problem is picking a latency that works both ways

 

Hmm maybe I should just split the difference and hope it averages ok? If I'm 1800-2000ms and the average is more like 600ms just set my latency as 1300ms and see how it goes?

I have everything imported into Baseline and setup. Now I just need to go take some logs and see what happens when I put them into Baseline

 

what parameter on the AP are you talking about adjusting here ?

 

Its a Baseline Paramater, so it knows what to expect when looking at the reported AFR vs commanded. I just ran it with an expected of 1800ms

Went and did a 15 minute log with lots of various pulls through different gears and a good bit of cruising.


Here was the first MAf output of Baseline and you can see Racetuner and the changes I applied to my maf scale. Oddly it thinks my upper scale wasnt too far off. I had pulled 5% or so off it since my dyno run.

 

On the Flash tuners - we only can read one injector, so we only set up one BIG *** one - it doesn't really matter since we can adjust when they stage anyway. I just need it there to tell you when you are encroaching 100% on your total fueling.

Your fuel table needs to be the same yes - now I have done this a few different waya. In my case I have a 1-3 and a 3-6 gear map, so I used my 1-3 and just log in those gears. On others with 3 fuel maps - I set them the same in the AP (saving the old ones), as in Baseline so I can log in all gears - once the MAF is sorted out then you can go back and set the base maps back to the way they were if you (like me) have the higher ones a wee bit richer.

 

Nice man..... the top end sometimes takes a few runs since your commanded is say 11.3 and your reported is 11.1-11.2, but the AFR is pegged rich there - so it won't show you the potential 5%, it just pulls 1 percent at time... heh - but looking at everything up to mid 4v range - that is pretty damn good.

 

When you are done and you want to get tricky and do some nats *** scaling let me know.

I have only done it to Jcab's car; but we got his MAF all but perfect.

 

Yep, I thought of the seperate maps thing and set them all the same. The only real difference for me was more fuel up top in gears 5-6, and I certainly wont be hitting those spots on the street anyway . So I'll change them back once I get my Maf straightened out.

I've actually run into a problem. After I made the first changes to my tune, I did the "get ready for new tune" steps. Changed my tune in the AP, and updated the Maf scale in baseline to match. I went out and got a new log(30 minutes) imported it with a new name, massaged it, then "Scaled the Maf". But the new tune name doesnt come up int he "View my tune information". Just the old one.

-Edit- Wierd, jsut restarted my laptop and now the new tunes are there :P

 

I get that bug sometimes too - close the main window and reopen it from the button on the left hand window (the one with all the engine info) and it will be there.

Also, you don't have to change the Baseline MAF scale everytime unless you change the voltage range - if you are just changing g/sec then you can leave it in there.

 

Looks like you are doing better than me in most spots... hehe.

I am going to do another round today.

 

Ahh ok, that will save some effot

This tool really does rock Kane. It sure beats trying to look at all that log data and guess what needs changed for each and every load(especially with my delay!).
Admittedly I tried using it 5 months ago and couldnt get my head around it. Now that I've been playing with my tune for 7 months I have a better grasp of what its doing(and what I need done) so I can mostly understand it.

 

Glad to hear good feedback man!

I have almost 1000 downloads and I can never get anyone to tell me how it went; LOL.

When you get most of the MAF inside 3% or so - then do the Tune Button, and see where your deviations are - then use that for the Fuel VE% map. After all that your next dyno should be a bit more motivating.... hehehehe

 

Yea, looking forward to the next dyno. I know I've got more than 300hp in it. Car is a beast in low gears. Feels much faster than my Vette did in stock form and that car had a torque advantage.

I think it really was because the car was thinking I was exceeding 200% load and retarding my timing. Since I've worked on the Maf the logs havent shown more than 180%, but I'm still only running 8psi. I am regularly hitting 4.5v with a 3.5" maf tube, thats got to count for something

 

Yupper - counts for fast.... HEH

I think I hit 4.49 (per my pic) volts last time out; and it was for sure scary in third.

 

I've run into an issue. I went out and did a good 30 minute log. I imported, massaged, then "scale the maf". I have to close it then reopen for it to show in the view tune window tab. But when I hit view map its blank? o.0

 

You mean the 2nd MAF scale?

 

Its just totaly blank. And it processes really fast like its not really even really looking at the log. I've cleared it out and tried to rerun it a couple of times, always the same result.

 

When you imported - did you verify the drop downs were matching up? When I rename some of my columns I get issues like that.

I have to go back and make sure all my drop downs are properly matched when I import.

Also did you massage the log file each time you imported?

 

Hmm..I've checked all that. Is it normal for the drop downs to use "#" instead of "." ?

Maybe I over massaged the log file and its too limp to be used?


yea somethign is up, when I hit "Scale maf" it just rolls right through it like it isnt processing anything.

 

Re- import again, and then go through each drop down box and select the option manually. And massage.

Let me know if that works - if not then I'll have you zip and email to me so I can fix it and send it back to you.

 

Still no worky

 

Your log file needs to be perfect for the import to work properly. Any issues I have had with imports were all errors in how I told Baseline my log file was...

 

I must have borked something in the baseline settings somehwere. I jsut tried it with a log that worked last night and it does the same thing.

I'm think going to go ahead and setup Baseline on my main Gaming computer(far far faster than my laptop) and start over shouldnt take me long now that I've been through the whole process once.
