ECU is a G4+ Thunder. I'd like a way of reading the hall effect output of the flow sensor so that it can be compared to the commanded PWM output to the water methanol solenoid. This controls the flow of water methanol through the system so there should be a relationship between these parameters. If the range of values from the hall effect sensor falls within an acceptable range (ie system flow is appropriate for commanded solenoid PWM value) then all is good, but if not, it will trigger a failsafe condition and switch back to standard fuel and ignition maps. Fot reference, the water methanol system I'm referring to is an Aquamist HFS3.

Great, thankyou Adam, will try and find a separate location for the tuning knock sensors, otherwise will give stacking a go!

Wondering if it is possible to split the signal of the knock sensor (Bosch wideband donut type) so that it can be run to the ECU (Link Thunder) and a KnockBlock simultaneously? Don't know if there is an issue with the input impedances of both devices being in parallel and lowering the amplitude of the knock sensor signal? Engine is a Toyota 3VZ-FE V6 with knock sensors located under the lower intake manifold. Reason for wanting to split the signal is because I'm not sure if there is a good location to bolt the sensors for the KnockBlock itself for tuning purposes.

Wonder if this feature (max and min tables) was ever added to the G4+ software, or there was an alternative solution found? Also have a hall effect flow sensor for water methanol injection that would be good to set up as a safety. Otherwise is the best solution still an external controller?
