No catalytic converter. True duals with thrush mufflers.

Sounds good guys...It appears to me that with my BLM being around 124 I have some run to lean out my VE a little. I think I will go in and LOWER my VE table by 1pt just in my cruising range and...

Well I am topped out on timing at 40 degrees in hiway mode with no knocks at cruise. Temps are still where they have always been...less than 190. I appear to be at an average of 14 mpg per the hack....

When I apply the patch the numbers go back to the original settings. It's like the numbers are locked and if you try to change them it throws some crazy numbers.

Yes...and when I commit it kicks the hiway patch out and it reads indeterminate data.

Im sure what is "safe" varies based on heads, compression, efficiency, etc... I was just going to do a...

AFR settings in Hi-way show:
16.10
16.10
16.10
15.90
15.60
15.50
15.40
15.40
15.40

I have all EGR functions turned off through a patch in the bin and the EGR has been removed from my engine. Should the BPW (base pulse width? ) change like that or is that an issue

I do see when the Hiway Lean kicked in toward the end of the log...the ECM went into open loop, the BLM locked and the timing went from 36 to 39 degrees..which is in line with the 3 degrees that is...

I am not sure why you would be seeing that much timing. I am around 36 at cruise....at least I think

I am posting my log and bin from today. Wanted to see if you guys have any further suggestions on increasing the MPG through the tune. I seem to be averaging around 14mpg (if the hack in my bin...

Alright...I am starting another post in the EFI section with the bin and log of the bin you sent.

I appreciate the help. I will be doing some traveling to day and will post up some data tomorrow

Thank you for looking at it. So I may need to get it to kick into PE each time before it will resume HLC?
I will run it this weekend and see how it reacts.

ASDU3 bin

here is the Bin....I appreciate you looking at it. I noticed the BLM is freezing so the hi-way mode is engaging. I just need to do some more adjusting to achieve better MPG. 12 mpg SUCKS!!!!

Cleared the codes and burned a new chip...I still do not see any indications that the Hi-Way Lean is enabling. I need some help and/or directions.

I attached the bin and log for you to review

OK...please review the attached log. I cleared the codes and ran another lap and I did not see any indications that the HiWay Lean was enabling.

sounds good... thanks

That may be the kicker....I haven't been disconnecting the battery each time I burn a new chip. I will grab a couple a chips, hit the bypass, datalog, wash, burn, datalog, wash, burn, datalog, add...

I am using all the latest XDF, ADX files, and TunerPro

TunerPro = version 5 build 5.00.8383.00
XDF File = $42-1227747-V5.9.7.xdf
ADX file = $42-1227747-V5.2.adx

I thought they were set up...

thank you...I will check on that.

Any ideas on why I would be getting an error 51 (prom error) ? I have burned 3 new chips and it is on all of them. Truck runs fine, and I can't see where it is causing any tuning issues but...

I will move the MPH up and burn a new chip. Not sure why that code popped up...must have a bad chip. Live and Learn and always fall forward...:rockon:

Sorry guys...I thought it was in the zip file I uploaded. I appreciate you guys looking at this for me.
