'''Acceleration enrichments''' subpage of MembersPage/DamirMuha When is activete it lasts for 10seconds (throttle is stady). This is my log * http://www.vems.hu/files/DamirMuha/datalog2007111515172.xls ** 263.32 sec : +1.9msec accelpw seen (12.5 => 14.4msec). '''You have a weird 49 => 64.3 kPa MAP spike!!!''' How is the MAP hose routed ? Maybe the MAP hose connects to a bad nipple (ment to maintain some vacuum for some actuator even at full throttle) ? **** It was routed thru 10cm 4mm hose. I haved strange readings(-+4kPa onda stady state). Than i add more 4m hose and now fluctuation are less. On full trotle map is 99-101kPa. ** 284.152 sec another MAP spike ** 288.97 sec '''lambda leans out, engine looses power. Iac starts a huge 60..20kPa fluctuation''', RPM fluctuation is also huge. You seem to be using very aggressive window for idle-ignadv (+-4 degrees ? Log has 12..20 deg ignadv as RPM changes) ** What values are good for idle-igadv? What's wrong ? Engine needs tuning ;-) VE tuning and some iac tuning as well. Currently it does not make sense to start transient tuning (accel enrichment), before it works well in static state. **Engine works very well when accel is off(lambda is good, full economy is good(better than standrad ecu), car goes much faster). This is my idle when accel is off. http://www.vems.hu/files/DamirMuha/idle.xls I have problem with my iac(it is broke, when is cold is 38% DC enough for 1200rpm, but when is hot 47% DC is't enough for 1000rpm). I will fix my iac later. * firmware 1.0.73 * http://www.vems.hu/files/DamirMuha/megasquirt200711151517.msq * http://www.vems.hu/files/DamirMuha/20071119mcd-saved.txt * http://www.vems.hu/files/DamirMuha/20071119mct-saved.txt * megatune VemsMT1.0.73Final I think that you have too long AE time, i think it´s seconds, not mS as it reads in megatune. I have those Acc amount values between 0.3-2.1 Not sure on that. I´m messing with c20let engine. By the way, i´ve noticed that when IAT is near 0c, IAC DC% is usually around 51-52 and when IAT is like near +20c that DC is then 54-56 depending on alternatorload and things.
