Has anyone come across things that help mileage wise. I'm seeing fuel shut off on decel and stuff like that so was wondering if any tweaks of those or other items were beneficial mileagewise.

Is it labeled as something different? I've looked through all the WOT and spark labels that came up with search but nothing that fit what I was looking for. Any suggestions?

Thanks!!

Tried the info given to me in the thread

Forgot to make adjustments each time I open a new XDF/bin.

This combination is what should work for a '94 Cobra with a J4J1 processor. However, the values are nowhere near what they should be, both hi and lo slopes are 112, the HEGO delay is all 0's, just to name a few. The program works great for my GUFB XDF along with my A9L bin.
Any suggestions??

That fixed it thanks, I printed that sheet out and put it in my folder so I'lll have it in case this comes up again.

Yes, mine is a 56K, but even the stock A9 bin does the same thing?!?

I noticed the XDF for GUFB is newer then what I had loaded so I downloaded and used it only to find all the values in most items like MAF are all the same from top top to bottom, in my bin and even the stock A9L bin. When I reinstalled the old XDF everything was back to normal. Is there something I ...

I found the CDAN XDF, but still not sure what to use for a BIN. Any suggestions??

Does anyone have one or know where one can be had?

I increased the ehaust pulse delay, higher then I ever have and it seemed to help it some. I'm going to drive it for a few days and see how it acts.
I used the spreadsheet from EEC tuning for the numbers.

I can watch the wideband and see it go leaner when it has been idling for a couple minutes.
I looked at some old datalogs and saw that at high speed cruise, where the RPMs were about 2800-3000 RPMs the load was in the high 30's low 40's.

Yes, I was sort of getting the hang of reading datalogs but EA helped me a bunch. So is there a way to make any adjustments to counteract what is happening?

You're thinking it gets to the WOT fuel multiplier with that extra load?

I encountered this when I had the EEC tuner in my car and was able to alleviate this by changing the exhaust pulse delay. Now that I have the moates chip and tuner pro I tried changing the delay and it didn't seem to affect it. I've leaned the MAF curve by 4% with no change either. At cruise the wid...

I took the idle start up adder to 0 already and am going to lower some of these others to see what that does. Thanks!!

Thanks, I had found all of those, but didn't know of buzz RPM. The most any of those boost RPM is something like 48 RPM.
If the TB airflow was off would that cause this issue? I have a 75MM and have TB airflow to .95.

When I first crank the car, especially when cold it runs up to about 1800 RPM for a second and then the idle settles down to normal. Is there a function/scaler I can tinker with that will tame this down a little??
I'm sure my neighbors would appreciate it at 5AM every morning.

Ok, thanks!!

Does anyone know what does this do?? Is there any point in manipulating the numbers??
I've got two XDF's an older version and a newer one. The newer one has all the values as the same whereas the older one has different values.
Any reason for this?

What would need to be changed to make this work? I understand EGR type would need to changed to 0 from 2. How would I go about getting it to add more EGR flow?
This is for a mileage experiment I'm trying. I am going to do a back to back comaprison to see what effect EGR has on mileage.
Thanks!!

Edit the xdf header (cntl + F2) and change the bin size to 'E000', put a base offset of '2000' in and check the 'subtract' tick box. I tried this method and it didn't work for me. I lost all of the functions/scalars. I'll have to download an editor and see if I can make that work. Edit> I'm officia...

If you are using the A9L xdf definition off here you need to ensure that the bin file is 64k. The first 8k needs to be padded out with null data so that the actual bin data starts at 0x2000. The xdf is set up this way so that the checksum calculation works correctly. I'm in the same boat, how do yo...
