What would be the RDX injector dead times i'd need to enter into FlashPro under Fuel?

Would I need voltage and time? or just the times?


I have already install the injectors and it seem to be kinda ok running on the factory settings.


see attachment....

Not sure. i used the dead times from the Injector-Rehab website on my 650cc injectors. Complete difference from factory settings. and I'm not sure if those are saturated or non-saturated. I asked RC engineering for stats and they only test at 13.5 volts. So I switched back to the factory settings since I'm tuning it at these settings. I'm sure if you send them in they can be tested. Maybe search Club RSX?

We've found that the injector dead times listed on various websites are far too low.

Here's how to tune the dead times. Start with a completely stock engine and a stock eqivilent calibration. Check the shart term fuel trim at various steady state load levels, and check your short term fuel trim is close to 0. If not, you have not got everything stock. Now swap in the injectors. What you need to do is to increase the injector dead time so that you still get a short term fuel trim of 0. You'll need to concentrate on injector durations of less than 2 ms, where the dead time makes the most difference. Ignore idle, as the AF will go all over the place from small changes in engine temperature. Only change the dead times for the 12V and 16V values - when running the battery voltage should be 14V. When you make changes, increase or decrease the 12V and 16V values by the same amount.

As a guide, typically you'll need to increase the 12V and 16V values by 100-300 (0.1 to 0.3 ms). Use 0.05 ms increments at first.

Is there a similar method for doing this if you're already in a modified or boosted setup? Perhaps from 1 of the base calibrations?

You need a completely stock engine in good running order to calculate the injector dead times.
