Injector scaling/latency problems.

Installed dwerks 1000's and a dwerks 340 and am now trying to dial them all in. Ive read the threads with latency values but the problem I am having now is: My ap software shows the scale in "ms(Injector pulse width)" when everyone elses seems to be in "Duty Cycle." The problem I am having is I cannot change the injector latency values to anything higher than 3.825 where it is calling for some as high as 6.xx+


Anyone on here know how to change the scale to duty cycle or have any feedback on how to get my latencies into a managable value?

Good morning! The reason you cannot go above 3.825ms is because the factory ECU is maxed at 3.825 (0xFF) There should be no need to go above this during normal operation at 14v. Once you've adjusted your latency for the operating voltages, you can then adjust your Fuel Injector Scaling to various values to dial in the injectors. I would imagine values between 880-920 should be good starting points unless your flow sheet is higher than 1000cc. Adjust as needed.

If for some reason you need MORE latency, you can always adjust the "Fuel Injector Base Latency" up to 3.825ms as well, which will be applied at all voltages on top of the normal latency values.

Thank You,
