Flow gauge for port injection?

whyzee125 · 07-07-2021, 06:25 PM

Hey guys,

I used to have a snow performance methanol kit on my e46 back in the day. It came with a flow meter to show when and how much meth was progressively flowing and it was really nice to know it was always working from seeing that.

On my e90, i have a PI kit and run full e85. Is it possible to do the same sort of thing with port injection?

I was thinking it would be pretty sweet to have it wired to a P3 or Awron gauge so you could always ensure the PI is spraying. Let me know if you have any ideas on how to make this work! Thanks!

NoGuru Here's a thread I made a while back about this. Nobody replied haha but I'd love to figure something out if you're still down for it too!

Okay, I am down to figure out something. I can't spend a lot of time right now as I am at work but I was thinking of a gage that can read a signal. I am pretty sure the AIC uses PWM or just an on/off type signal. Once we figure that out we can do how much is flowing or just if the unit is on or off.
My car will go into storage in about two months but I am sure we can figure it out before then or we will need to rely on you for all the testing.

I'm excited about this lol, appreciate you wanting to collaborate. No rush, I know how life gets haha. I don't mind doing the testing on mine too as time permits! I'll do a little research on how the Snow performance meth setup works, I bet it wouldn't be too difficult to copy and apply that to the PI.

I'm about to have a conservative 93 map made for track/road trips too so especially if I'll be turning the PI on and off, it will be very nice to see that it's working when I think it is.

Anyone got any ideas on how to do this? Happy to be a guinea pig if you want to make one too, I really want to do this!

I forgot all about this. I have 3 kids under 5 so I don't know if I will ever get to it but I should be getting the car out in a month or so.

Heck yeah! If I or someone else can come up with anythinng, I'll definitely post it here as I remember you were interested in this too.

I have zero electrical knowledge but am fairly determined to get this done so I think I'll find a way!

the snow performance flowmeter+display will work on a PI kit. just install the flowmeter between your PI manifold and fuel-in line (might need to change fittings). if you have the parts, msg me part#s and i can draw you diagram how to wire it up.

iam going to be running 650cc PI kit with motiv controller to spray meth, i was also going to install a flowmeter for confirmation, but with just a simple LED light in cabin to trip when flow active or below desired cc/min and another LED to trip via Motiv controller when it signals for meth from PI

This is fantastic news, thank you for the reply! Please do PM me that diagram if you don't mind. I don't have the pats but I'll definitely order them. I use a Split Second controller if that matters! I also have an LED wired up to show when my secondary fuel pump kicks on but it would be super great to be able to see when the PI is spraying.

I want to get the P3 gauge, and that has an LED light input that can be used for whatever--figured I'd use that for my fuel pump spraying and then maybe the snow performance gauge for the PI. I wish the Awron gauge could be used for the PI but it seems that's actually less adaptable than the P3 even though it has an incremental light function.

PS2N54 · 02-22-2023, 12:04 PM

the P3 and Awron guages use digital input via cars OBD (with exception for analog vacuum input on some) so you cant just plug a sensor direct to it, you'd need to get a custom tuned motiv controller to do 2way communication with the car and use it's external sensor input, and even then i dont know if P3 even has interface for it, since its hard coded.

the snow performance flow guage + flowmeter would probably be the most straight forward option, and only wiring would just be from flowmeter to guage (should already be provided in the kit) and you can tap voltage from your splitsecond controller for the sensor, and in the cabin you can use a "tap a fuse" kit to get power to the gauge.

I have two n54 with PI and monitor the funtion of it on the jb4 app and probably Terry would be able to assit you with gauge instalation if you have jb4 contoller.

Thanks for the reply feuer! I'm flash only but would consider adding a jb4 just for that functionality if it works pretty well.

For me works ok, on the app shows under fuel additive, amd on the logs as meth trace. If you have scalling info on the gausge you want to use I'm certyain that Terry can make it happen.

whyzee125 · 02-23-2023, 10:04 PM

Guys, I think the P3 might work?

Check out the top row, it's got some sort of function that shows whatever input ramping up, and it says it has 2 analog inputs that range from 0-.5V. That's a variable thing and not like an on/off switch, right?

If there's a way to integrate this that would be so slick. LMK what you think.
