Sorry I've missed this thread until now Hadi.
Can you provide the following info;
1) When you did the flow test WITH the Max Extreme in control, did you do so with the settings you mention above, that is to say, were you pulsing the system?
Yes2) If so can you connect it all back up and set ALL the power settings to 100% and retest the flow.
I finally had the time to do so. Reconnected the Max and set all the power settings to 100%
Conducted a flow test and same thing. Passenger side is flowing more. 3) When you mention relays, can you tell me how you have them wired in to the system, please?
I followed this diagram
http://www.noswizard.com/pdf/MaxWiring1.9_8A.pdf
Instead of using one relay for both sets of pulsoids, I used 2.
Each relay's 30 terminal is connected to the battery's positive with 12 ga wires (fused)
Each relay's 85 terminal is connected to the battery's negative 12 ga wires used
Arming switch wired to both 86 terminals getting its power from an unused 20 amp ignition source in the fuse box.
Each set of pulsoids + is connectd to Its own relay's 87 terminal
4) The frequency you selected should NOT affect the flow, especially from one pair of Pulsoids compared to another.
5) I VERY much doubt the Max is the cause of the problem.
6) Can you tell me how you have the Pulsoids connected to the Max?
Using the above diagram both nitrous pulsoids from each bank connected to 11 and both fuel pulsoids connected to 107) Can you tell me how you have the grounds connected to the Max?
directly to the battery negative
1,2,5 and 7 are unused and they're also going to the battery's -
The rest are tucked away Can you tell me what version of the Max you have, this info is shown on the screen when first switched on?
Street ver 7.20Hopefully I'll be able to work out what is causing the issue from the answers you give.
With regards to how to proceed in the absence of a solution, as long as you aren't running overly lean on the bank that is getting least fuel, there is little to no risk of continuing to use the system as it is, at least until we find the cause.
