Got back late yesterday afternoon, and after a quick SS, headed off to the car shop. Got there at 10pm.. crazy ramadan hours.. open from 8pm till 3am.. wtf.. anyways...

Pressurized the brake system... it works!!!!!

Also did some logging for new tune.. but yeah the brake system works!!!! That was a huge unknown....

Just thought id say it again, Brake system works... obviously not sure as intended yet , but brake pedal holds pressure and exerts (a lot) force on the rotor... not sure if its enough.. street test will define if were cracking a beer over that or not.

but yeah man.. that was good to see...

traction is gone... but thats to be expected as the bmw e46/m3/z4m version of traction works by applying brake pressure to the rotor thats has a percentage of slipage. and pulls power from the engine.. as now there is only a direct connection with the ABS pump, and nothing else, its expected that that traction system ceases to function... which is what we wanted, but we wanted to keep the ABS... need the ABS... not sure if thats working yet, but hopefull.. i mean it should... ... i hope....

The dash lights up with the combo signal for ABS/DSC, which is to be expected for no traction control.. will code that light out later..

Edit: note on traction:... Some of yoyu might be reading this and thinking WTF, you /WANT/ traction control.. yes.. agreed if your in the wet, and not the stock traction, but setting
TDR
aktiv

would be whats required for that, however , as this is just a track car, at this stage, ill be good without traction. (dry track only)
but yeah, had a good night talking shit and running the car chasing any oil leaks.. which there werent. (oil and filter change completed too last night) frikking crap how much castrol is... an extra 2L required due to the larger capacity oil cooler.
