Meth under part throttle/boost?
So the BMS fsb only allows meth to flow under full throttle correct? Anyway to start meth flowing any earlier using the fsb?

Who said anything about not making much power? I thinking more like an activation around 10-11 psi.... This would solve the problem I have, when I floor it I have a second or two of "no meth" . It takes time for the fsb to activate the pump but if it activates at a little lower boost setting it would eliminate that issue.

You've got it all wrong OP. The meth normally starts flowing when you hit around 8psi >. The FSB is a failsafe control box that measures current from the pump so it has nothing to do with the meth being activating. At WOT it only takes a split second for the meth to start flowing unless you have issues with your setup.
As enrita said post a log. |

My meth comes at partial throttle as I'm going to full throttle, that's what makes it a smooth acceleration. Meth used to be only at wot giving you the dropping the hammer feeling...... Now it's so much better

Or you could get the CMGS V2 controller and use it that way. That's how I have mine set up, it kicks in at around 3psi all the way to max.

Ideally you want a meth system that uses a pulse width modulated valve with the pump maintaining a constant pressure to provide a better dynamic range. If you're also able to fine tune the injection curve then you have a nice system |

Ive looked at numerous csv/logs and it shows meth activating only after full throttle was applied...but I have never logged while easing into the throttle. Last night I did slowly get to full throttle and I did see flow before my pedal hit the floor. Part of my problem is that I use a WW kit and it gets air in the line on really hot days. I have to power purge multiple times for good flow. Looking to start running 100% meth so hopefully when I get around to putting in my trunk tank it solve my air in the lines problem..

thats because everybody logs only on wots. i would stay away from WW kit especially if you want to run 100% . many cars caught fire...

Ive started with WW kits in every car I have owned that was under boost (5 total) and used only boost juice or winter blend fluid and knock on wood no fire... The funny thing is the only car I switched to a trunk tank was also the only fire Ive had with meth (100%)... Ive had a under hood tank melt because it broke loose from it's mount, this caused it to spill meth blend all over the engine/turbo. No fire but I was only running 45/55. Im not stupid enough (my wife would disagree) to run anything over that under the hood...
What additive setting do you guys use for 100% meth?

I may try and bump mine up to 50 (from 40) tomorrow. I run about the same e85 % as you do but a lower meth %.... You ahve any recent logs you can share with the above set up?

Never tried it but I love my JB4 and I wanted to stick with the same tuner for my meth control... It works fine thus far, I just with it had a boost/meth adjustment.
