http://i131.photobucket.com/albums/p304/soopa325i/3.jpg Installing VEMS on M20B27 BMW engine.This is my first VEMS project,and first standalone project ever,so i would need all the help i can get! :) Tnx My goals are to get NA engine running on VEMS and doing a few dyno runs,paint car, then go turbo. 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? 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 # changed to 66resolved problem 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 PROBLEM SOLVED! wbo2_calibration was way too high (started out with A8) and all i was doing is going higher never tryed out to lower it (?!) then i tryed A1 and i get O2 something like 24.7 and i get 20.9 on 66 (hex) so i`m continueing my work... ---- Work progress: I got spark,need to set Injector settings and start the engine for the first time. Curently using stock coil and 60-2 wheel with stock VR trigger sensor,i`ll update it later to some 200sx COP's since i got them in my garage and i heard that they'll do the job correctly. ---- Update: While trying to solve the problem,found that Injector on cyl2 isnt working so i rewire it to another FET now it works,engine cranking and want to start,from 7xx rpm goes to 0 and then again to 7xx again to 0...TriggerErrors red button is glowing after few seconds.Engine is haveing spark,using stock coil,stock 60-2 wheel,stock VR....if more info needed please ask! Plase help! Here are logs and config files http://www.vems.hu/files/MembersPage/MilanaPerisic/config.txt http://www.vems.hu/files/MembersPage/MilanaPerisic/tables.txt Cranking engine log: http://www.vems.hu/files/MembersPage/MilanaPerisic/mt_datalog_m20.zip TriggerLog from Terminal: http://www.vems.hu/files/MembersPage/MilanaPerisic/trigger_bmw_m20_log.zip Update: I found R30 soldered on board,i removed it and then i lost RPM signals,spark...so engine is dead now on cranking...Any1 have a clue?
