MAF Flow Chart

You need to tell us what you are trying to do

Grady

You are good to go

You will simply tell the pcm you got 30lb inj's
and
Use a generic 30 point ProM 30lb transfer curve found in the Cal Edit maf files

Life is good this time

I thought it might be good to offer just a little more info about your original Q

Even if by accident you ended up with inj's & maf caled to their same size, you did good

YES, you could just use those 30's and the ProM maf caled for 30's. You can do this because of a cheat method the maf companies have devised.

I've posted lots of info about this before so I won't go into it all again.The main thing to remember is with 24's, the cheat method may or may not work reasonable well. 30's have less of a chance of working well with the cheat method because the larger the inj size, the more ineffective the cheat method becomes.

Since you got all options available to you, you don't need to cheat or lie to the pcm anyway.

Just use your Tweecer to tell the the pcm the truth about inj size and air flow of your combo.

btw, if you wanna know more about that cheat method and why a good deal of peeps are confused about inj's, mafs, why some are caled, why some are not, etc, there is a small article on my site that can help.

I'm sure I could get a copy of someone else's Pro-M80R flowchart. Is there any advantage to doing so? Would that be a better starting point than generic 30 data?

Click to expand...

Your first choice would be the original flow sheet for your exact meter. You would then use that flow sheet and one of several methods to generate a 30 point curve.

Your second choice would be a generic 30 point curve like we talked about above.

You would not wanna use say my 30 point curve as it is specific to my combo.

What is gonna happen in your case in a nutshell is:

1 Your gonna go for the second choice generic 30 point curve.

2 Tweec in your inj values for 30's. After you get things as close as you can with the inj values.

3 Tweec your lower part of the maf curve for Closed Loop. Most likely just a point or two as this is kinda like fine tuning.

4 Tweec your higher part of the maf curve for Open Loop or WOT. This is gonna be using fuel tables and Wide Band.

I bet you can hardly wait

Its gonna be great
