[FYX193]

I have your 3 Bar Progressive Controller and W/I kit with a Solenoid and using 2 nozzles (M3 & M5) hooked up to my SRT-4.

I have an AGP 3147 turbo kit with approx. 375+/- whp on 93 pump gas @ 19psi of boost.

I am curious if I should continue to use the Progressive Controller to trigger the W/I system or if I should trigger the system based on boost and RPM using my Zeitronix ZT-2 wideband datalogger along with the optional ZAVT-1 warning/trigger box to activate a relay to trigger the W/I system under specific conditions. Example: I can set the ZT-2 to activate the trigger box at 4000RPM and 15psi of boost.

I have full boost by 3200RPMs, and I don't see any Knock Retard until about 4500RPM till redline where I approach 6 counts of KR. I am curious if I would be using the W/I system unneccessarily in the lower RPMs if I am triggering the W/I system at ~3000RPM using the Progressive Controller in my particular application. I could see the use with the stock turbo since it runs much hotter due to excessive back pressures from the smaller manifold/turbine. But on my AGP 3147 I don't have excessive pressures/heat unless at the Higher RPMs & boost levels.

I can trigger the W/I system using both methods, I'm just curious which is the most useful for my application.

You lose all the progressive controll of the unit, It simply becomes a on off kit like a boost activated system. You want to start injecting sooner to start adding the cooling and octane to prevent knock and not try to stop it after it is already happening.
