My O2 sensor is placed at end of the header before it bolts to the exhaust pipe about 3-4 inches based off my memory. I was thinking of taking it on the route and recording a winaldi log and...

Yep it is weird at first I thought it was elevation but I live in wisconsin I get the good mileage when I am heading south. I live at 1,473 feet the usual route I take leads me to wausau wi 1,195...

HI guys I have a mileage question for you. I have a 1980 scout with 304v8, 89 gmc truck TBI, custom chip, vss, self heated O2 sensor, tuned by myself, with lean cruise initiated thanks to Mark works...

THanks that was very helpful! Great work! I will have to save up for a droid type device to use with the program. Not sure how to exactly decipher if a device has droid capability? I am guessing some...

HI guys can someone tell me is it possible to put winaldi or tunerpro onto a Ipad or chromebook or some other slim device. I was thinking it would be nice to make a spot on my dash for it and run...

Good idea, however it also doesn't work on the same roads going the same direction. so i don't think it is the kpa....

Please keep ideas coming, I must be close?????

Hello Mark here to report both good and bad news. I have been able to get the bin to work with my AFR settings for lean cruise. I raised the open loop Max AFR to from 15 to 16.6. Also installed the...

I was using this XDF from you: $42-1227747-V5.9.5.xdf

-Should I try the new one you listed?


-I am using TunerPro to make changes to the bin and they are being saved.


-I guess I am...

Hello Mark, you got it right it works just fine then I change AFR and it stops working. I only raised to 16.10 in the 50 map column I was going to do more but it quit working once I made the change....

Another idea , I don't know if any of this helps you? However, I used the difference tool in tunerpro between your patched settings that works and the one that doesn't work with my air fuel changes...

Hello Mark I don't have a data log but that could be arranged. I usually data log in Winaldi. Would that work for you? I have never done it with tunerpro not sure how. Hopefully I could make a...

Hello Mark, I went through all the steps again and made sure everything was set correctly for engaging highway mode. It still wont work and the only difference I can find is it says "Indeterminate:...

Thanks eagle mark it seemed whenever I had "Indeterminate: data does not match." and tried the chip it did not engage lean cruise mode. Maybe I missed something else. But it worked when I left it...

-On a hunch I tried (Save bin as) instead of (save bin) and it still won't let me keep my new AFR settings that I would like to try. I am officially lost on this one can anybody tell me what I might...

Hello the good news is I got the Highway lean cruise mode to work today and can see it come on with my wideband LM-1. Bad news is I can't adjust the AFR chart for highway mode and save it and burn...

Hello Mark, good news I believe! I got the patch to work by using the patches under the parameter tree. When I first compared the my old bin to new it was 55bytes different. A few questions for now!...

Hello Mark, if I have time tonight I will try again on the bin and let you know if it works. In the mean time I have a general question for you when tuning for best mileage at cruise/

-is it best...

Hello Mark I downloaded Tuner Pro and was able to add my bin and then your xdf. file. It all looks good and then when I hit (patch bin) all I can get is a Patch failed box. Not sure what I am doing...

Thanks for the reply Mark! I am fairly computer illiterate but I don't see how the new patch fixes my issue of my computers giving me this message (Can't open output file: 60227) everytime I try to...

Hello eagleMark I'd like to thank you for posting up how to initiate the lean cruise mode on the 7747 ecu. I have had TBI on my 304 v8 scout motor for 3 years now and want to try this for more...
