One more question. The maf tables have limits , can I adjust that too? Like the first table only goes to 23.00 I think. What if for example I want 24.5?

Thanks!

DanielRicany

They can be adjusted. Just so you know the last cell in the table should be the same number as the first cell in the next table.

Billygoatkid

Ok , I understand the transition has to be smooth from one maf table to the next, where can I adjust limits to each maf table? Seems limit for maf table is 24. Should I adjust my injector pulse width so less adjustment is needed?
Thx for all the input!

You are correct, there is a limit for each table and it cannot be changed unless you chang the actual code for the tune. You will have to tune around this issue or see if someone can give you a modified code that does not have this issue.

Billygoatkid

Ok thx
I found a xdl file that someone gave me last year that expanded the 4+3 Nash transmission, and included was to adjust scalar. Yay! Back to data logging I go!!
What's the first number in maf #1 so high?

Billygoatkid

Ok I think that the maf tables are adjusted pretty fine. I'm ready to adjust for wot. What's the best way to do this?

DanielRicany

First of all, I'll need to know what numbers you entered in the first MAF table so I can tell you what to put at the first cell.

Secondly, do you have an AFR gauge? You will need one to do WOT tuning.

Billygoatkid

Yes I have a gauge

9.12
3.53
4.90
6.47
8.73
11.27
14.61
19.51
25.00

That's the table

DanielRicany

Can you post the numbers in the stock MAF 1 table as well? Thanks

Billygoatkid

The original numbers are:

8.38
3.24
4.5
6.22
8.38
10.9
13.96
17.75
22.34

What do you do with the numbers?

DanielRicany

I would recommend setting 0.00 volts at 8.96 gms/sec.

Also, what you need to do is find out if your AFR is the same all throughout the power band. Do a pull in third gear from around idle RPM all the way to redline and see if the AFR is pretty much the same all the way through.

Billygoatkid

I'm also interested in the reason for this. Thanks for the input, but why is this number larger in the original maf table

DanielRicany

What number?

Billygoatkid

The number on the first line of maf table #1. Why is this number larger than the seconc third and forth numbers?
Is this idle?
The number you suggest to change, its importance?

DanielRicany

Not sure. Could just be for cranking when there is hardly any airflow. The number I came up with was an average of the percentage changes for each cell.

DanielRicany

Also, did you manage to find out if your AFR is even throughout all RPMs?

Billygoatkid

Hey, thanks for the reply. I only have one bung welded into the header collector on one side, so I'm going to have to rig something up as I use that for O2. I've run one on my sportbike by means of a wire directly into the pipe . I'll see in next couple days if I can do that.

I'm looking at tables in tunepro for wot change and don't see exactly the ones you specified .

Billygoatkid

Which ones? Thx

DanielRicany

Power Enrichment Vs. Temp and Power Enrichment Vs. RPM

Billygoatkid

Thank you !
Those tables look pretty basic ? I'm positive it's lean wot, but will confirm with afr gauge.
Any suggestions on increasing the tables?
