Got another noob question for ya's.. im about to try my first crack at real time tuning tomorrow and was just wondering,what is the correct way to SUBTRACT fuel or spark?..i know how to add fuel/spark as there are = + x next to the box at the top of both tables..but no ( - ) minus symbol for subtracting fuel/spark..how is this done correctly?
For timing just do -1 and click the add button. That will just subtract from wherever you highlight.
Fuel is the same way basically. If you want to remove 2% from a given area you highlight it and enter .98 and multiply by that. Just like adding 2% would be 1.02%.

If you don't post your tune and logs when you have questions you aren't helping yourself.
awesome,thank you for the quick response,much appreciatedOriginally Posted by 5FDP
Ideally the drag and drop of fueling would be done once the table(s) are pretty dialed in, otherwise if you were to just kept adding or removing from random points throughout the MAF curve or VE you could get a roller coaster looking MAF and a hills and valley looking VE table.
Try to do large sections or specific sections at the time to minimize future problems. Like work on part throttle and medium throttle together while doing either the MAF or VE using an AFR/lambda error or if you have to with fuel trims. Several longer logs should easily do a larger section of the tune if the data is right. Past that would be medium to full throttle tuning to finish off the VE/MAF.
Once done then it's faster if you know you need just 1-2% added/removed here or there as it's such a quick fix.
