While self tuning the car for knock detection i noticed some inconsistency&#8217;s at varied boost levels. Id sometimes hear pinging, sometimes not. Every inspection of the cylinders and spark plugs turned up nothing of significance to be found. Was it knock or was it engine noise? its hard to be sure. The yellow top 555cc injectors I have been using were advertised as genuine JECs, but they did come from ebay and were under $100 shipped for all 6, Highly suspicious. I also did have a incident in 2019 with cylinder 2 detonating with one of the yellow tops that I later determined was a flow variation between all the injectors.<\/span><br \/><br \/><span style=\"font-size: 14pt;\">Another part of the equation is the fuel I&#8217;m using. I pumped out 3\/4 of the fuel in the car in May because the fuel was from October 2025. I put in new 91octane fuel from a gas station I never got to. Maybe that fuel was bad? maybe the mixture of old fuel and new fuel was enough to lower the octane? nether the less I was hearing pinging at timing and boost ranges I wasn&#8217;t last year and Id feel more comfortable knowing the injectors were quality and measured professionally.<\/span><\/p><p><span style=\"font-size: 14pt;\">I decided on Deatschweks 550cc Nissan Injectors. At 43.5PSI of fuel pressure they are effectively 637cc injectors. They feature a special atomizing metal pintle cap that requires more fuel rail modification, otherwise they are drop in for fuel rails already modified for Nissan injectors. A very beneficial thing about these injectors is accurate pulse width and deadtime settings witch im documenting here that may be helpful for anyone using these same injectors. I already did the conversions for these settings into Megasquirt 3 using 1.6 version deadtime settings.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-43df5ae e-flex e-con-boxed e-con e-parent\" data-id=\"43df5ae\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-856d0af elementor-widget elementor-widget-text-editor\" data-id=\"856d0af\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><span style=\"font-size: 14pt;\">For comparison sake, these yellow tops are similar to what I purchased off eBay. I actually purchased 2 sets of 6 and they all function and measured exactly. The durability of these injectors remains to be known. They worked, but side feed injectors, <\/span><span style=\"font-size: 14pt;\">specifically Nissan side feed do a have a reputation of failure and inconsistency&#8217;s.

I used a 10mm drill bit for this process on the Mill\/Drill and afterwards I put the 10mm drill into a hand drill and ran it thru the bore by hand ( holding straight as possible) this imprecision of doing it by hand was enough to make the injector slide in and out perfectly.<\/span><\/p><p><span style=\"font-size: 14pt;\">Depth Chamfering Pintle Bore:<\/span><br \/><span style=\"font-size: 14pt;\">A 11.5mm -12mm chamfer needs to be bored a the top of the pintle bore approx. 2-3mm into the bore.
