anndrew0 Posted October 10, 2021 Report Share Posted October 10, 2021 Nearly ready for the first start, running yarris cop via dizzy cam sensor for now. I have the cam sensors and spark but when I test the injectors i get nothing. They are raceworks 1000cc injectors high impedance dead times in the photo. The neutral for the injectors are grounded on the back of the head. Could this be causing them to not trigger? Thanks in advance Andrew soarer base.pclx Quote Link to comment Share on other sites More sharing options...

anndrew0 Posted October 10, 2021 Author Report Share Posted October 10, 2021 ahh that would be my problem, apologies i don't know much about ECUs. ill re wire and try again. Thanks for the quick response Quote Link to comment Share on other sites More sharing options...
anndrew0 Posted October 10, 2021 Author Report Share Posted October 10, 2021 Got the injector test to work. had a look on my trigger scope and im only getting 0.2v. This is just noise isnt it? would you know if the ge distributer wiring to the ecu should be NE Trig 1 - B27 G1 Trig 2 - B25 G- Ground trig 1 is 12 tooth 1 sync for crank trig 2 is cam pulse x1 sorry im sure this gets asked all the time cheers Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 10, 2021 Report Share Posted October 10, 2021 Yep wiring sounds ok. On the trigger scope, did you click capture while the engine is cranking - not before. Quote Link to comment Share on other sites More sharing options...

anndrew0 Posted April 24, 2022 Author Report Share Posted April 24, 2022 hey mate got a chance to have a look at the car again. how's this trigger scope look.

Adamw Posted April 24, 2022 Report Share Posted April 24, 2022 Trigger voltage is fairly low, drop the arming thresholds to match example below. Quote Link to comment Share on other sites More sharing options...
