Isn't that what this screen is for? What would you want to change it to, and why?

 

The only reason you would limit the min/max trim is reduce the fluctuation. This applies more to when you chagne injectors/map sensor, etc. The stock settings with the stock wideband should be just fine.

But what I was suggesting is to narrow the min/max trims that way your a/f ratio is more steady when trying to tune the car. That way you are relying more on the O2 sensor readings and not the short term %.

 

That makes sense. Thanks.

 

i have the same problem i did not change any min/max trim settings cause my car is running the stock injectors map sensor etc i find it extremely hard to tune in part thottle my wot af ratio is ok is there a certain way you datalog for part thottle or i just drive around in the city? i try to do it like the flashpro help says but it didnt help me at all my car is burning more gas for city driving please help

 

Don't change that table at all. Changing it too much results in the car wanting to run in closed loop at WOT. Just so you know.

 

THIS makes part throttle tuning on the street easy.

 

thanks! it looks time consuming since my laptop battery is dead and i cannot live tune but i will give it a try

 

the 2nd fuel map on the first post has a few large gaps. mainly between columns 7 and 8.

i like to aim for stoich from columns 1-6. start richening it out as it gets to column 7-8. try interpolating between breakpoints.

 

Gosh ... it's been so long since I created this thread, I didn't even realize it was mine! I've gone SO FAR beyond this.
