Choose CT200 if you need 6 standard injectors. Choose CT400 \/ CT450 \/ CT500 for GDI \/ EFI \/ FSI and long injector work. CT500 is the featured professional option with 15 functions and 12V \/ 70V \/ 120V support.<\/div><\/details>\n          <details class=\"autool-ct-faq-item\"><summary class=\"autool-ct-faq-q\">Does CT500 support GDI injectors?<\/summary><div class=\"autool-ct-faq-a\">Yes, CT500 is positioned by AUTOOL for GDI \/ EFI \/ FSI and standard gasoline injectors. It uses 12V \/ 70V \/ 120V drive modes. Always select the correct voltage and confirm adapter fitment for the injector type.<\/div><\/details>\n          <details class=\"autool-ct-faq-item\"><summary class=\"autool-ct-faq-q\">Can CT Series test diesel injectors?<\/summary><div class=\"autool-ct-faq-a\">No. Diesel injectors are cleaning-only in the ultrasonic tank. Electrical testing and flow testing of common-rail diesel injectors require a dedicated diesel injector test bench.<\/div><\/details>\n          <details class=\"autool-ct-faq-item\"><summary class=\"autool-ct-faq-q\">Can CT150 test GDI injectors?<\/summary><div class=\"autool-ct-faq-a\">No. CT150 is for standard gasoline injectors. Buyers needing GDI should compare CT400, CT450, CT500, FN606 or FN608.<\/div><\/details>\n          <details class=\"autool-ct-faq-item\"><summary class=\"autool-ct-faq-q\">Does the machine include test fluid or cleaning fluid?<\/summary><div class=\"autool-ct-faq-a\">Do not assume fluids are included. Use the package list for the active SKU. In general, buyers should source proper professional test fluid and ultrasonic cleaning fluid locally unless the selected package explicitly includes them.<\/div><\/details>\n        <\/div>\n        <div>\n          <details class=\"autool-ct-faq-item\"><summary class=\"autool-ct-faq-q\">What fluid should be used for testing?<\/summary><div class=\"autool-ct-faq-a\">Use professional injector test fluid in the graduated cylinders. Do not use gasoline, corrosive solvent, diesel, paint thinner or ultrasonic cleaning fluid as test fluid.<\/div><\/details>\n          <details class=\"autool-ct-faq-item\"><summary class=\"autool-ct-faq-q\">What fluid goes in the ultrasonic tank?<\/summary><div class=\"autool-ct-faq-a\">Use professional injector ultrasonic cleaning fluid. Do not run the ultrasonic function without fluid in the tank. Do not use the ultrasonic cleaning fluid in the measuring-cylinder test circuit.<\/div><\/details>\n          <details class=\"autool-ct-faq-item\"><summary class=\"autool-ct-faq-q\">Can I test one injector at a time?<\/summary><div class=\"autool-ct-faq-a\">Yes, but unused positions should be plugged according to the machine setup. This keeps pressure and fluid behavior consistent.<\/div><\/details>\n          <details class=\"autool-ct-faq-item\"><summary class=\"autool-ct-faq-q\">Is this a guaranteed fix for misfires or poor fuel economy?<\/summary><div class=\"autool-ct-faq-a\">No. Misfires and poor fuel economy can come from ignition, compression, sensors, air leaks, fuel pressure and other causes. CT Series helps test injector behavior and supports a better diagnosis; it does not guarantee that cleaning will fix every symptom.<\/div><\/details>\n          <details class=\"autool-ct-faq-item\"><summary class=\"autool-ct-faq-q\">How should a shop present results to customers?<\/summary><div class=\"autool-ct-faq-a\">Photograph the baseline spray pattern and graduated-cylinder volume, run cleaning, then repeat the same test.
