My A/F target ratio is set to 15.86, and the actual A/F ratio is 15.86 at idle. How do I change this?

I looked into the online manual; and found the table I need to adjust; TARGET AIR/FUEL RATIO vs RPM and MAP. I can't find this table, on the C-COM software. BTW I am set to SPEED DENSITY.

So how do I find this table, are how do I reset the A/F ratio to idle the car richer.

142 views but no one knows anything about the FAST XFI 2.0.

Surely someone must know how to tune a FAST fuel control unit.

Did you try contacting FAST, or you could try here http://www.gearhead-efi.com/Fuel-Injection/forum.php

STH

Yes;I finally got through to the FAST help desk after two days of calling, the table names on the FAST software do not match the names in the FAST instructions; very helpful

Thanks for the gearhead web site, will give it a look.

I have briefly seen the fast tables I believe it was based off the gen 7 dfi which I have. can you post photos of the table options you have? are you tning with a wideband? (assuming yes). On the Gen 7 dfi there is a table showing map vs VE, this is the fueling table. If I can see what youre looking at Id be happy to try and help if I can

It is under view closed loop parameters, and then target A/F table.

STH

This is the table I find in the Closed Loop Parameters. The table you displayed is what shows in the help file but I only see the Target Lamda Table.

bjankuski

Multiply all the numbers you see by 14.7 that will be your afr. When I will get home I will look up the location of the lamba to afr display change.

bjankuski

Underneath the file tab there is a command for lambda mode, click that and it will show afr instead of lambda.

Is the fast EFI as simple to install as they say? Is it a good system?Thanks,Steve

I bought mine from Dan White Racing, with his adapter that allowed me to plug into the stock harness.





Again a little dusty, showing the FAST XFI with the Dan White adaptor, and the Holly HSR.
