john civic rally Posted January 16 Report Share Posted January 16 hi, i have a civic ek with a b16a2 mapped on a g4+ plugin ecu. it has b16b cams and 410cc rdx injextors. i am having trouble starting the car for the first time when cold. it takes around 30sec cranking to start and usualy the smaller battery dies a couple of times and needs help. I am wondering if somebody can help me figure out or improve the cold start settings. once it has been started and i shut it down immediatly and i start it again after 30sec it starts in a couple of seconds. i added the tune civic rally full power 190whp + launch 8000 _ TPS MAPPING+TIMING final.pclr Quote Link to comment Share on other sites More sharing options...
Adamw Posted January 16 Report Share Posted January 16 Can you provide a PC log of a bad cold start? My initial thoughts would be towards things like trigger arming thresholds or ign dwell not suitable when battery voltage is lower and cranking is slow.

remski2 Posted February 28 Report Share Posted February 28 Hi. None of your logs show 30sec of cranking.. and also your logs dont provide much data either. Add all of the parameters to logging and relog... Quote Link to comment Share on other sites More sharing options...
