I picked up a 6395 PCM at the local salvage yard from a '94 4.3. I found the $0D .xdf off TunerPro's website. As well as a .bin from who knows what. I may just try to pull the stock tune to start with. I'm going to transfer the current spark/fuel tables I have from the tuning I have done so far in my 8746. I have found the 'main spark tables' but have yet to find anything that would hint towards a fuel table. I just downloaded TunerPro v5.

Should I keep looking for another .xdf that would have the fuel tables displayed or are they hidden under some sort of description? I know there is a lot about AFRs but nothing to change the actual values.

 

Are you referring to the VE tables? If you select Parameter Category in the parameter tree you will find VE tables listed. Here is the titles of the VE tables and a list of some of the other fuel related tables:

Open Throttle VE vs. MAP vs. RPM
Idle VE vs. MAP vs. RPM

AE vs. MAP Difference
AE vs. TPS Difference
Open Loop AFR vs. Temperature vs. Vacuum
Choke AFR vs. Temperature
PE AFR vs. RPM
Crank to Run AFR vs. Temperature
Crank BPW vs. Temperature

As far as I know, this is the most complete $0D xdf available anywhere.

 

That covers my question completely. Either I forgot that VE was for fuel or I just missed it completely. Thank you. Hopefully I can get this up and going for summer.

EDIT:
What I should have asked about is disabling EGR. This may require some hacking or else looking for a different .xdf

Close thread... SEARCH worked great.

 

I didn't notice until tonight that you made this .xdf. Thank you so much for doing it.

 

Your welcome, enjoy!

Did you get the answer you needed for the EGR?

 

I noticed that once I got some good sleep I was able to realize there is sooo much that can be manipulated with this mask. Yes I found all the enable parameters for the EGR.

However there is one last thing. What unit of measure is the VE table in? Before I was able to set BPW (which I have not yet figured out but assume it is computed using Cylinder Volume and Injector Flow Rates). From there I used BLMs to compute what needed to be added in the VE table.

This new(er) PCM must use time? As in it computes that it needs to be on a certain duration and then I add milli or micro seconds in the VE tables?
