I just installed these RC 1300cc injs.

But should I be concern of injector failure for not using the secondary often to flush them out?

Do they kick in at boost or rpm?

 

i believe the primaries come on then the secondaries are slowly brough on, then the primaries faded out a bit and the secondaries brought totally in

i think this happens right around 3800

 

negative, it happens at different rpms for different boost levels. wade has a website and with his help, i did an excel chart thingy which tells exactly when it comes on for a stock power FC map (which should be some what close to what the stock ecu)

they pretty much come on line when the primaries get to about 70% duty cycle

its called injector staging, here is wades page http://www.wvinter.net/~flanham/wlanham/ and here is the maps http://www.wvinter.net/~flanham/wlan...mapcharts.html

 

so what is the best way to run inkector cleaner to clean any of the contaminents that might be in the injectors without blowing up the engine?
