Alpha-N and closed-loop

[hyro]

I think you can. Haven't tried that though. But I think the extra resolution will just increase tuning hassle and time.

i just tried it and it is possible.

time will increase, but the estra resolution will give you more precision, me thinks.

in MAPxRPM, the idle was in column 3-4 and when we release the gas, reads in columns 1-2.

now with TPSxRPM, how can we reproduce this behavior?

You cannot. Both idle and release throttle load reading will be 0%. You should not care about this though. It is normal.

ok. thanks.

it will be interesting to modify the maximum MAP for closed loop to maximum TPS for close loop.

what do you think?

[CivicVTi]

This is done automatically. If you have:

Min MAP:0kpa
Max MAP: 100kpa
Max MAP closed loop: 50kpa

THen your max TPS closed loop will be 50%.

ah, ok. it is calculated like this.

tps closed loop = (Max_Map - Min_Map) * (max_closed_loop/100).

civicvti, which values did you use on TPS columns?

you say that we need more resolution in lower tps openings and less resolution in higher openings.

would you post these values to take a reference ?

thanks in advance.

It's really up to you. I think I used:

1%, 3%, 5%, 7%, 10%, 12%, 15%, 20%, 30%, 40%, 50%, 75%, 100%

With boost values of course (13 total columns)

ok, thanks. just to take a reference from a succesful tuning.
