Based on your normal driving patterns. For the same TPS, different gears will produce different loads. So seems like you'd change TPS settings if you want to always go into open-loop at a certain TPS (it's not gear-dependent this way).

I think you should not change the load Open Loop tables at all.
change only the TPS Open Loop tables.
because like the other person mentioned, gear dependency is not a factor.
cruising your around 25-40 TPS. So just decrease this just above so that way when your race your instantly there and ready to go!
I make my open loop low load all 30 from 4250-5750 RPM
70 from 3500-4000 RPM
i make my open loop high load all 30 from 4250-5750 RPM
50 from 3500-4000 RPM

The reason why i set 30 in low/high load from 4250-5750 is to combate lift off knock, the open-closed loop fighting problem.

I am confused...You said not to change load open loop tables and change the tps tables. But then you say that you changed your open loop load tables and set them a certain way Could you please clarify?

I belive the Y axis address is wrong on that table, change it to 6124 and see what I mean.

sorry for the confusion, I left my load dependent tables stock. I only adjusted my throttle tables.

I am curious that if these can be verified by a log or WB? I think that your idea makes sense but am wondering since there are differing opinions on this....

Could you post the maps so we can have a visual? Could you tell us why you used these numbers?

can you please elaborate why you feel that changing the tps tables are the better option for making the car stay in open loop than changing the load tables?

So with this, no changes need to be made to the fuel tables? If so, which cells exactly?
