What is a trim code on an injector?

What is a trim code on an injector?

In short, trim codes or trim files are codes that go into an Electronic Control Module (ECM) that determine how long a fuel injector injects fuel into a cylinder for. Not all engines require trim codes. Be sure to check manufacturer’s instructions.

What do the numbers on fuel injectors mean?

Fuel Injectors are sized by their flow rate. Flow rate is a measurement of how much fuel can be delivered over time. For example, a naturally aspirated, 300 hp engine (BSFC 0.5), with 8 injectors will need 23.4 lbs./hr. of fuel per injector at an 80% (0.8) duty cycle. (300 X 0.5) รท (8 X 0.8) = 23.4 lbs./hr.

Do you have to program injectors?

The resulting engine performance will be poor including high fuel consumption, lumpy running, and poor high NOx emissions. It is advisable to perform coding after testing an injector to know that all its measurements are within tolerances and that the resulting code will contain that established information.

How much horsepower can 1000cc injectors handle?

The 1000cc Injectors can support 650+whp.

What’s the trim code for a cat injector?

Double-click on each trim code one by one & enter the new trim number. When you replace an injector with NO trim code visible, you can use 1100 which is the Cat default trim code. Anything is better than running 5232 or 6999 in all 6 holes (04-15-2014, 06:02 PM)Scrapper Wrote: I have one for trim codes, not files. The old 4 digit codes.

Why do fuel injectors have different trim codes?

They are all made the same way, after all. But due to slight differences in machine tolerances, friction between parts, and magnetic forces, some injectors have different rates of output. By using trim codes to adjust the injection duration for each individual injector, the net output of the injector for each cycle is the same in an engine.

Do you need a trim file for an injector?

There’s your problem. You need the all full injector number to get the correct trim file for the injector.

Is there a 4 digit number on the injector?

There is a 4 digit number on each injector. Can i use that number to replaced the 6999? Yes…use the 4-digit number from each injector. Go to the “Service” tab in ET, select “calibrations” and then “injector trim”. Double-click on each trim code one by one & enter the new trim number.
