This is my attempt to turbocharge NA car (and not to grenade it)
022906032DR (c167) file equipped with DQ250 F-series
Pulsar G30-900
- mono lambda patch
- load limit not presented in this file (thanks bosch for tons of random changes in similar files)
- n75 connected to pin #116 (pw3, pp3 = 12499)
- implemented prj`s boostcontrol
- IAT sensor relocated to manifold
- all ram variables of boostcontrol redefined to 387* instead of 384* this eliminate misfires, even if IDA shows empty space here, probably some ram-mirroring was there, ive faced this before so just swap it with 387xxx*
- RLVMXN/RLVSMXN maxed out to eliminate IOP limit and gives adequate misol_w, now its misol > miist, no torque intervention and car runs smoothly, ps_w, msdk_w, pvdks_w finally sorted out
- changed turbo routine instead of feeding pwm it manages new ldtvm_w to be able to log wgdc and move pwm operations to its raster
- somehow i got inverse pwm so a bit of calculation was added:
mov r5, ldtvm_w
mov r4, #30A3h ;100% WGDC
cmp r5, r4
jmpr cc_ule, loc_ldrNext
mov r5, r4
loc_ldrNext:
sub r4, r5
...
- DPUPVDK map calculates pvdkds_w based on ml_w in stock its subtracted map values from pu_w and i replaced it with addition due to map is not signed, this gives positive pvdkds_w and msdk_w now looking nice but i still thinking to replace it with native map sensor- map sensor fitted pre-tb, pin #85 (brake boost pressure sensor in stock), DSBGRAD/DSBOFS as the sensor settings but i change routine to 1.8t because it didnt handle overflow, call from DPUPVDK result with rets so its basically replaces DPUPVDK calculation, i have not implemented sensor failure path due to time management
car runs smoother after that
- patch for b_mdee (enable redsol) when shifting, so it gets selective fuel cut at shifts but unfortunately without noticeable sound
so far so good, DSG works completely fine, input torque, clutch pressures looks adecuate
Now questions:
- probably i want to emulate KFVPDKDS / KFPLGU stuff but im not sure how to make it simple way
- going speed-density?
- intake/exhaust cam settings? i have no idea how to do it, probably ive got a dyno but some hints would be nice to hear
