wideband error offset - i need your results EVERYONE

Post by decipha » Mon Jun 27, 2016 4:24 pm

well the time has finally come, for years everyone has been wanting full time wideband control, amongst many other hacks, well, decipha is finally going to answer all of your prayers, a couple years back i wrote the full time wideband control code for gufb, i soon realized that without free ram it was a futile attempt. Well this morning i had a brilliant idea which solved that problem. So now that I have a means as soon as time permits im going to put it into action.

What I need from everyone is their accurate wideband transfer as entered in BE or the like.

All transfers would be great the more the merrier but if you have a known transfer and had to correct it that would be best.

Im trying to figure out how i want to apply my correction factor to the inputted transfer function for accurate wideband readings.

Would this only work for gufb, or could it be ported to other strategies as well?

the major code chunk can remain the same but it will have to be revised for each strategy, the kamrf table lookup has to be modified and in the case of cbaza since it has no free rom you have to delete some unused routines for the code

im actually working on it on cbaza for now since im daily driving "The Legend", bout to hit it with a 250 dry shot so im working on the n2o code for cbaza now as well

This is very cool news! I'm not sure what you are looking for in error offset. Can you explain more?
Project #1 '88 Mustang GT-40P heads, Explorer intake, Crane Compucam 2030, BBK Long tube Headers.
Project #2 '50 Willys Jeep CJ-3A '86 Mustang SVO swap. Convert to Speed Density?
Project #3 '87 Mustang GT Explorer 5.0 engine and EEC-V computer (other stuff TBD).
Project #4 '80 Porsche 924 Turbo, to EEC or not to EEC that is the question?

I was looking for your actual stoich voltage vs the proposed voltage by the wideband manufacturer

since no one replied i went through all my notes and came up with a correction average not exceeding 10%

How would you determine your *actual* stoich voltage? Compare it to the narrowband switch point?
