Boost control

[maRS2]

I don't know if it's my car or the or every motronic managed RS2/S2 but i hate how boost is controled at Midrange.


What I hate is that when I'm on part throtle seams sometime very low and theire is a big transition to full throtle I means part to full throtle transition isnot smooth at all . it's like on/off.
So when fast driving in mountain road with lot of trafic on narrow road it's very hard to modulated acceleration to pass car's it like full power or midpower , black or white no grey.
I don't know how the boost is control by the motronic but it seams that the boost is related to throtle position and not to what turbo is able at X rpm and that their is a big step in between the different boost map for part throtle and full throtle.

I have stiffer spring in WG an MRC remap it help a bit.

Now I'm thinking to go to the electronic boost controler route like apexi , blitz or gredy
I know i will loose the oem boost security
But i will be able to control spool up,boostcurve and max boost in every gear and to have a very smooth transition from part to full throtle as the management will only be of what the maximum boost can be delivered by turbo at xrpm and the boost limit i set up for this x rpm
it's what i remenber from my ex subaru with apexi boost controler very smooth

apex avcr does boost control that you can program at differnt revs, conditons etc IIRC

Wab the king: I know i had one on my ex subaru and it's why i'm thinking to go this route but would like to know if somebody have experince with some electronic boost controler on 2.2 I5 turbo

If you search there is one long thread in particular that springs to mind, that gives a lot of details

tekkno uses a greddy boost controller on his s2
