please allow me to chime in, Aquamist has a Flow sensor assembly I think that could solve the issue according to the way it's works not hindering the flow.

Seems to me a pressure sensor on the rail would be the best solution. Flow sensor will still read with a leak at the rail, external or injector. Pressure sensor could detect a leak, no flow, stuck open injector, leaky injectors, etc. Both pressure and flow would be great but the jb4 only has so many ins and outs for this stuff. The other added benefit of a pressure sensor is there are already lots of ethanol compatible factory rail pressure sensors out there. just need to adapt one for our use.

as it is known , the JB4 Controller crashes with FSB , when you remove FSB , this time the pump does not work , so does the nozzle in the charge pipe , which causes the IAT’s high output. How do we get out of this ? Can we spray Methanol from charge pipe with CPI under the control of bms controller ? Is bms controller capable of triggering the meth pump ? As last thing , What should be meth safety and meth trigger settings in the PMI system?

The bms controller has a trigger wire that you need to use to trigger a relay that supplies power to the pump. So yes the pi controller will trigger the pump. If u want to still run a cp nozzle just tee Into the meth line going to the fuel rail. Recommend something pretty small. Or you can grab fuel-it cpi injector and use it instead of a nozzle and splice it into the injector harness so all 7 fire at one. Last option is to have your tuner scale your tune so the iat reads cooler than actual iat temp. Rest assured your iats are actually cooler but the cooling is happening after the tmap. Or just buy a better intercooler

we are in the same boat sir, patiently waiting on them questions to be awnsered. really want to make this system work

I've used their stand along flow sensor in the past... It was just OK. But probably the best of the ones out there. Wire it up with the flow signal going in to the JB4 15/16 and let's evaluate it.

The FSB is a pressure sensor and while that works well in a normal setup, with PI meth there are many failure points. Lines could pressurize but injectors not open, for example, so not ideal here IMHO. On the plus side with pressure info we could setup the JB4 to scale meth flow on meth pressure. So when pressured dropped it could automatically scale IPW on the injectors up.

Terry.... should the wmi pump pressure be turned down if running PI using injectors? Since the pump set over 200psi and injectors are set for 50-60psi?

Also would a AEM wmi guage would help making sure we have meth flow since JB4 Lets us know injectors are getting a signal

Awaiting instruction on how to get this working. I am on holiday for a few weeks and ready to be the Guinea pig if it does not involve running high boost without knowing if the pump is on or not

Duty bias is set per map in the single turbo firmware...

What is the WMPI setup, fuel, etc, here? Bank to bank trims look good which is normally a good sign.

Main thing to look for is bank to bank fuel trims which seems OK. Other than that log seems OK to me.

They both usually last at least 2 years or more.

Quick question on my setup my injectors arent opening. I'm 100% sure meth pump is xoming on. On my logs Fuel EN amd meth both get a signal but injectors arent injecting. Is it possible even tho I'm getting a signal that the controller might be bad?

Have you checked the harness that connects to the connectors?

I did, not sure if I did it correctly and if results were with in specs. If the harness is connected to the injectors and I unplug from the controller from it I get continuity on that plug. Disconnecting the harness pin by pin fallowing each wire has continuity and about .04 ohms.
