johnny_9 Posted December 4, 2012 Report Share Posted December 4, 2012 Calibrating the Triggers (Setting Base Timing) on a B16a This what I get from the default file for Gen 6 Honda - are these good starting values? Offset = -85 degree BTDC (seems a bit extreme?) Delay = 0 microseconds Quote Link to comment Share on other sites More sharing options...
Simon Posted December 5, 2012 Report Share Posted December 5, 2012 As the trigger mode is generic and covers a huge range of applications the offset is often very far away from 0. You will just need to adjust on the car to make the timing correct. Quote Link to comment Share on other sites More sharing options...
Stevieturbo Posted December 25, 2012 Report Share Posted December 25, 2012 I did a B16A a year or two ago and it came out around 175deg. I fitted a coilpack to mine afdter frying the amp inside the Honda dizzy, although still used the dizzy for the trigger. Quote Link to comment Share on other sites More sharing options...
Stevieturbo Posted January 6, 2013 Report Share Posted January 6, 2013 Trigger offset is you telling the ecu when TDC occurs relative to the crank trigger wheels markings. It has nothing to do with the cam position as such. Quote Link to comment Share on other sites More sharing options...
johnny_9 Posted January 9, 2013 Author Report Share Posted January 9, 2013 Technically after setting timing at idle rpms, and we rev to say 3,000 rpm, and there is a "drift" - what actually is the causing the drift, and shouldn't it get worse at say 6000 rpm?

Simon Posted January 9, 2013 Report Share Posted January 9, 2013 This is what the ignition delay number is for. This corrects for the retard in timing as the RPM increases. If you are using the Honda igniter make sure you have set the dwell edge correctly as it is opposite to most applications. Quote Link to comment Share on other sites More sharing options...
johnny_9 Posted January 11, 2013 Author Report Share Posted January 11, 2013 Ok thanks. The "retard as RPM increase" - how much is that normally? 2 degress? Just want to understand more. Is that steady higher rom fixed at say 5000 rpm or As you blip the throttle 3000 - 5000 rpm - retard happens as the engine as throttle is blipped - and is this more to timing belt flex or a delay in the electronics in the ECU Quote Link to comment Share on other sites More sharing options...
