l0ch0w Posted May 8, 2012 Report Share Posted May 8, 2012 I'm in the process of building a custom base map for a 3sgte engine with 2150cc injectors, individual coil pack ignition, and a gen 4 caldina crank trigger with a custom hall sensor setup for the home position sensor. My big question is this... I know around idle that my pulse width is supposed to be hovering between .5ms and .6ms on these big boy injectors, how exactly does this master fuel trim thing work? Here is my understanding of it... If I set my master fuel trim to 5ms, that means that at 100kpa load, 100 in the field equals the the 5ms I input as the master fuel trim? Meaning that for a .5ms pulse at 40kPa at idle with the master fuel at 5ms id have to input 10 in the field? Quote Link to comment Share on other sites More sharing options...
l0ch0w Posted May 8, 2012 Author Report Share Posted May 8, 2012 let me rephrase, does anyone have a base map for 2150cc injectors in a 2.0L? Quote Link to comment Share on other sites More sharing options...
lemmy01 Posted May 10, 2012 Report Share Posted May 10, 2012 :wow 2150ccm would be good for 1300HP or did you use E85? Sorry for OT, i think it's not easy to find a basemap for that setup. Quote Link to comment Share on other sites More sharing options...
l0ch0w Posted May 14, 2012 Author Report Share Posted May 14, 2012 Yes, its for e85 I know that its not going to be easy to find a base map... I do have access to base maps from other EMS's but I dont know how to convert them into the vipec maps... My big question is in regards to the master fuel trim and how to adjust it to give me the injector times that I need. Quote Link to comment Share on other sites More sharing options...
Simon Posted May 15, 2012 Report Share Posted May 15, 2012 05. to 0.6 mS seems a very low pw for idle. MAP: 35 kPa RPM: 1004 Fuel table number: 57.7 Inj deadtime: 1.019 No fuel trims Master fuel = 4ms (Note this is the minimum) Inj Actual pulsewidth = 1.825 ms Inj Effective pulsewidth = 0.806 ms Quote Link to comment Share on other sites More sharing options...
bsh Posted May 15, 2012 Report Share Posted May 15, 2012 I have an 2.1 engine with ID2000 (same as yours?) injectors running E85 that you get the fuel table from. Send me your email on my pm. Remember it is only for startup. Quote Link to comment Share on other sites More sharing options...
l0ch0w Posted May 17, 2012 Author Report Share Posted May 17, 2012 PM's must be down or something... I cant seem to access them anywhere?
