I finished my harness few days ago,waiting to get some time to try if i got spark,then i`m going to wire everything else to Genboard and try to start the engine. My pic galery: MemberPages/MilanaPerisic/Pics Current engine configuration: * m20b25 head * m20b25 engine block shortened for 2,4mm * m20b27 eta crank * m20 rods 130mm * m20b25 pistons (8.8:1 pistons from 325i Cat.) * Schrick cam 288 * M30 AFM (i`m glad i`m getting rid of this think...) * M50B20 injectors (same cc like stock 715 injectors just got 4 little holes and you get nicer fuel fog) * Motronic 173 Dyno results with 205/50 R15 159,6HP and 230Nm Planned configuration for turbo: * b20 head with b25 valves,welded water channel,3 angle valve job * b25 engine block,normal height * 524TD crank,rods * equal lenght tubular split pulse turbo manifold * Schwitzer S3,got few turbo so i`m going to try witch one gives best results (Schwitzer,Holset,KKK) * Huge FM intercooler * 55lb injectors * walbro 392gsl * schrick 288 * wasted spark * 50mm wastegate * wbo2,EGT,knock * ... ---- '''Sensors''' * Throwing out MAF ? I`ll be using onboard 400kp map sensor * What TPS will you use ? I`m using M50 TPS fiited to M20 intake * What MAT (airtemp) sensor will you use ? There are a few MAT sensors in ** [http://shop.vems.hu/catalog/index.php?cPath=1_12 webshop] I`m going to use one from FIAT Punto 1.1,its like "Temparature Sensor" from webshop just its fitted in nice plastic housing. * WideBand O2 * EGT sensor ---- '''Ignition''' * 3x2 wasted spark module ? A: For the NA engine,that i`m curently working on,i`m going to use stock coil,with turbo,yes,i was planning to use 3x2 wasted spark module from Opel Omega B,Vectra B,Calibra V6 (same bosch number as one from the webshop] * Stock 60-2 wheel with stock VR sensor ---- '''Fuel Injecton''' * MSD/Halley 55lb lowZ injectors from [http://www.racetronix.com racetronix] * Walbro 392GSL inline fuel pump ---- Problems: I finished the harness so i started to calibrate and set up the "things".I have problem calibrating WBO2,i cant get O2 readings...? This is voltages that webshop sent me in my email,should i try to get this voltages? The details of your Genboard: Board_version=v3.3 Serial_nr= 1036 pump-= 4.15V wbo2_pump_pw_zero=0x68 pump+= 4.31V this is my config: > wbo2_abs_limit=E4 > wbo2_limit_maxt=A0 > wbo2_fallback=B0 > wbo2_retry_t=06 > wbo2_edgetime_corr=BA > wbo2_edgetime_min=50 > wbo2_ri_target=00 > wbo2_nernstdc_target=7D > wbo2_pump_pw_zero=68 > wbo2_calibration=A8 - i tried this one with larger value,no results > wbo2_heater_pid_kp=46 > wbo2_heater_pid_ki=10 > wbo2_heater_pid_kd=1A > wbo2_heater_pid_ilimit=80 > wbo2_pump_pid_kp=15 > wbo2_pump_pid_ki=4E > wbo2_pump_pid_kd=00 > wbo2_pump_pid_ilimit=84 > wbo2_ri_confidence_scale=80 Heater is working,the sensor is little hot when i touch it after some time.While sensor was outside,not in exhaust,while i was assemblimg the unit i saw some readings,but now when everything is ready and i got all harness done and sensor in the place where stock sensor was,no readings. How is possible that i had AFR reading at page2 after some time (mlp02),heater was on,so instead of geting O2 i get AFR readings,Engine off, Like this: ... AFR:20,98 O2:??.? AFR:9.09 (or ??.? this is target afr or?) Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ...
