Karl_tate Posted July 14, 2018 Report Share Posted July 14, 2018 im at the stage of trying to start but I'm getting no rpm signal. im running ffe hall sensor aem coil wired direct fire EDITED... karl peril.pclr Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 15, 2018 Report Share Posted July 15, 2018 Do you get a spark if you use the ignition test function? Trigger 2 sync mode should be set to none but I dont think that would stop it sparking. Are you getting RPM displayed in the software when cranking?

Karl_tate Posted July 15, 2018 Author Report Share Posted July 15, 2018 No spark with the test mode. Not getting any rpm. So it must be the settings for the ffe hall sensor?? Also have I got the ignition setup correct for direct spark Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 16, 2018 Report Share Posted July 16, 2018 This indicates you have two seperate problems. Test mode will work regardless of trigger signal. If you get no spark in test mode then coils must have either no power or a wiring problem. What specific AEM coils are you using? Your trigger settings look ok (except for T2 sync mode mentioned earlier) so it seems you may have a wiring issue with the trigger also.

Karl_tate Posted July 16, 2018 Author Report Share Posted July 16, 2018 The coils are getting power as I have tested for that. All the earth check out fine as does the signal wires. Aem smart coils. Should I have it set to falling or rising. I've turned trig2 mode off now. Quote Link to comment Share on other sites More sharing options...

Brad Burnett Posted July 16, 2018 Report Share Posted July 16, 2018 Now I cant say for sure on the rotary trigger modes, but with a standard piston engine, if the trigger 2 is config'd to something other than none, there will be no spark. Ran into this problem on one of my own cars, was running 60-2 crank with multipoint and wastespark. Up graded ecu and trig 2 got mistakenly set to cam pulse and had me chasing my tail for a few hours. Quote Link to comment Share on other sites More sharing options...
Karl_tate Posted July 17, 2018 Author Report Share Posted July 17, 2018 Thanks for your input. I have turned trig2 vvt to off. I get trig1 signal ok when cranking but no rpm Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 17, 2018 Report Share Posted July 17, 2018 Do a trigger scope now and attach that. https://1drv.ms/v/s!AiYbYlZQuRHPmieMTkwQDCXEb2LY Quote Link to comment Share on other sites More sharing options...

TechDave Posted July 23, 2018 Report Share Posted July 23, 2018 Trig1 isn't showing any signal, it's just sitting at 10V. Was the engine cranking while you pressed capture? Quote Link to comment Share on other sites More sharing options...

Was the engine cranking while you pressed capture? I pressed capture then cranked?? When I'm cranking I get trig1 signal goes from no to yes though?? Is the sensor too close?? When I received it, there was barely a gap. I would go as to say, touching. I have taken 1mm off. Maybe not enough?? Is it maybe because I have wired it with 12v?? Surely that should read 12 in stead of the 10v the scope says?? And the ecu is looking for a different voltage?? Quote Link to comment Share on other sites More sharing options...

Karl_tate Posted July 24, 2018 Author Report Share Posted July 24, 2018 sorry. redone it scope.llg Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 24, 2018 Report Share Posted July 24, 2018 Ok so you dont have a trigger 2 sensor by the looks. Set trigger 2 sync mode to none then tell us if RPM is displayed correctly.. Your trigger 1 looks ok. Quote Link to comment Share on other sites More sharing options...
Karl_tate Posted July 24, 2018 Author Report Share Posted July 24, 2018 Trigger 2 is set to non. So the sensor is ok then?? Quote Link to comment Share on other sites More sharing options...

Adamw Posted July 24, 2018 Report Share Posted July 24, 2018 I dont see much wrong, I would expect to see RPM. Your statistics suggest the ECU has seen a valid cranking RPM at some stage. Can you do a log of it cranking: https://www.youtube.com/watch?v=_P1LRANeO4A Quote Link to comment Share on other sites More sharing options...
Karl_tate Posted July 24, 2018 Author Report Share Posted July 24, 2018 What a complete dumb ass. Previously. I wasn't cranking it long enough for it to register an rpm Signal. On that scope log retry I kept it turning over longer to log. Which it did, and will of also given that rpm result , but I wasn't looking for that at the time. Bangs head against wall several times..... Thanks for all the help people. So what timing settings etc do I need for the direct fire setup.
