Adam the ground on the relay to sensor ground, or could go to chasis?

Im finishing an s50b32 install of a link g4x i have 2 questions 1-can i use the knock shielded cable for the intake cam sensor it have a ground and a positive and its shielded , and im not going to be configuring the knock control for now. 2-Does the car start without vanos wired in , that seems to be one of the confusing part and dont want to delay the process anymore , hence im thinking on installing vanos delete. regards

so everything could go to ground and sensor ground pins on my link

does this ground go to the link ecu sensor ground or need to go to chassis or block ground PGND fuel inj output stages PIN 6 PGND remaining output stages PIN 34 PGND Ignition output stages 55 Also whats ANA GROUND and ground point connect regards Copy of M50-vanos-vs-s50b32.xls

normally open relay right?

Hi I'm mapping out the wire diagram on my car i got pin 56 switch to 12v and pin 27 to main relay and pin 26 battery voltage whats is pin 54 flyback / power should i connect all of them to the 14v on loom A on the plug and play version for bmw i see 56 ignition switch / main relay 56 is the same on both ecus and pin 54 +14v from main relay / ecu power on s50b32 FLYBACK/POWER 27 MAIN relay control / not used on plug n play version Copy of M50-vanos-vs-s50b32.xls

Hi , could i install a pnp link g4 ecu for s52 /s59 us model into an euro s50b32 double vanos if i change the pinout i saw on my link software content that link have instructions for an s50b32 so i supposed it could be made to work regards

Hi can i install this bmw pnp link ecu on a obd 1 s50b32 z3 M euro specs

hi i have issues with my link reading a fixed map voltage doesnt matter which sensor i plugged in ,the voltage is fixed on the signal pin around 2v so the car have 0 vaccum or boost reading , the ground is good ,5v at pin 3 and good signal on pin 2 cable to the ecu have continuity the ecu , the fixed volts for signal is the same on ecu and connector at sensor

hi is this a possibility? so i can control all my fueling in closed loop using my wideband?

a) Set Ignition delay to 0. b) Using a good quality timing light, increase RPM and observe ignition retard. where i observe ignition retard? on idle im at 10 btdc but if i accelerate to 5000rpm i lose the mark on the damper on subaru the mark goes over to 30 btdc c) Increase Ignition Delay and repeat step b) and c) until the retard is eliminated. d) A typical value is between 20 to 80 microseconds.

hi i have 2 question why when i use my launch control it keep itself engage althou its already running and why my speed dont go over 180km/h + pase 1 is where i had the lc active and it didnt disengage pase 3 i with lc disabled but speed sensor didnt go over 18x km/h car is trapping 210+ disregard the knock signals the map is a little rough and the knock is not enabled yet vp map 450 trigger 0 deegrees 505.pclr vp map 450 trigger 0 deegrees 505 - no lc after 11.2.pclr pass 3 cip.llg pase 1 cip.llg

i think my trigger is indeed funny im 10 deegrees over on my tune and still making power dyno log 443.llg idle 2.llg Trigger Scope Log 2019-03-15 10;48;56 am idle.llg vp map 450.pclr

2 fuel pumps inside a tank with their filters

5500rpm no load right just accelerating while parked what do you mean fuel pickups like the fuel pump filters?

I dont see any limits/fuel cuts/etc kicking in. Your logs dont show the lambda values or fuel pressure though so its hard to get the full picture. Without this I can really only guess Lambda values around .95 / 1.05 once it hit full boost at around 5400rpm Do you have a screenshot of the lambda graph from the dyno from either of these pulls? specifically I want to know if gradually crept up once you were on full boost, if it suddenly just jumped at some point, etc. it didnt crept gradually its like .78 then .95 /1.05 Is your fuel regulator boost reference working correctly? yes its working right its new i dont have a fuel pressure gauge inside the car but we kinda watch it on the dyno max calculated fuel flow in those logs is around 2050cc/sec - so around 120LPM which even after losses in the lines etc, you should be able to hit with any decent aftermarket pump (assuming your lines are big enough and the pump has big enough wiring to supply current) how can i calculate the max fuel flow , im using twin pumps a 340lph + 465lph to a an 8 line to big rails and ID1000 injectors the wire is gauge 8 positive and ground could this be the issue? that could not supply enough volts for 76 psi fuel pressure? Were you feeling misfires as it got above 5k on the 3rd gear pull? your RPM jumps around a little bit which could be misfire or it could be trigger issues. If all else fails, grab a trigger scope at 5400-ish rpm. could you explain a little better the trigger scope part?

im tuning the car the fueling is ok up to 5500 after that it goes super lean 15 afr lean like im out of fuel pump fuel pump base pressure 4 bar i want to know if there is a correction or something on the map that could be cutting my fueling i tried the charge temp approximate table under boost at 100 and 0 does the same thing iat correction on and off does the same thing, the car have 2 new fuel pump and id1000 with a gt35 turbo at 16 psi so i should have plenty fueling im leaving my map and logs to see if somebody can steer me on the right direction or give me some pointers i suspect that i may have some correction or limiter pulling fuel after 5400 but i dont know if this plausible after innundacion no lc.pclr dyno pull 3rd gear.llg dyno pull malo 2 2nd gear.llg

resolved thanks

i have an issue the tps of my v6 sti the tps is not working when the engine is running if i turn the engine off and just switch to the on position without starting the tps calibrate perfectly and starts but whenever i switch to run it will stop reading attached logs and file Log 2019-02-1 10;11;04 am no tps.llg Log 2019-02-1 10;11;41 am yes tps off ignition.llg Fixed1 frank scaling 2 scaling 2 all sensor.pclr

base timing 10 btdc when cranking now that i add more fuel and idles base timing is 8 btdc so i guess i should have some offset adjustment to do what offset number would you expect to see

we are close now sputters loggin sputters.llg

hi this is the map and log disable correction - test.pclr loggin dont start.llg

i have a link g4 with 210 lb injectors on an sti ver 6 the car have the COP conversion if i test injectors and coils through link everything is connected fine i calibrate the trigger but it will start for 1 second and sputters if i test the injectors before starting it starts for 3 seconds and dies can you help me set my starting map i zero out all corrections to try to simplify it but nothing

i resolve it for now i did a wiring from the battery to a relay that is being energized by the factory fuel pump relay + better ground and more juice for the walbro 450

it is necessary to disable hold ecu power when changing from isc stepper to isc solenoid?
