Hi all!
I have stock injectors on my SC RX8. The max boost is 8 psi. The max torque is at ~3500 RPM. The boost rises above 0 at 2000RPM on WOT.
1. I going to set up staging % to 70%, staging RPM at 2000, staging boost at 5Hg . Am I on the right way?
2. I try to explain. Fuel map shows 1ms pulse width for primaries. The real pulse width is 1.7 ms (+70%). Pulse width of secondaries is 0. Later RPM rises above 2000 RPM and a vacuum become below 5Hg (staging online). Primaries and secondaries run with 1 ms. Am I right?
Sorry for my English.
Thank you.

From the Microtech site....this is what I understand about the staging setup in Microtech ECU...

this is not the IDLE/AUX setup that the IntX uses....INTx is set at 0% staging...and doesn't use it

If your below the Mapstage value..and above the RPMstage Value...You get primary injectors firing with %stage adjustment value

If your above both Mapstage and RPMstage ...you get Primaries and Secondaries firing at there set values

The %stage value has no effect after secondary injectors are turned on

The larger the difference between Pri and Sec injector sizes...the larger %stage value required to get smooth transition

Thank you! It's clear for me now.
