Doesn't look like the B58 charge pipe?

Sounds like you have a fault if it won't prime, as it works for me, and all the others I know who fitted.

Use something like this for the fuel, makes it easier and get no spills,

thanks for the tip, that is a B48 charge pipe with single CM7 nozzle, how do you prime it, you just press the button in the BT APP and it squirts?

95% denatured alcohol is about 1.3 -1.4 USD / L here at the local pharmacy actually is good deal I think I will run it unless someone tells me not to, actually washer fluid is more costly at 1 USD for 50%, so it turns out to be 2 USD / l for meth in the washer fluid....

I just posted logs in support forum it looks to be working well timing for example is much improved peaks at 21 PSI and hold onto 19 . Very similar to B58, as that is all I have to go on as nobody else really posting anything for B48 on meth, however I assume they are pretty similar minus 2 cylinders, why didn't I get the 140i you ask, it cost 25k USD more here....

If you need tech support use the support forum, or email in if needed!

Must have meth map map7 selected before the prime button in the interface will work.

Yup that was it, I didn't start to tune yet so I was still on my original map, thanks.

I played with the boost safety function by max out signal scale it works really well immediate and obvious and gives you a gauge swipe when activates, very cool.

Where did everyone tap in the FSB 12+ power wire from? Looking to see which wire you guys used (B58 cars)

It goes in the fuse box per the WMI installation guide.

I connected it to the main power on the LHS. It's protected by the fuse at the end of the day. Works perfectly, and convenient as I have mounted the fsb next to the JB4

Anyone using the progressive WMI control yet?

I thinking of maybe dual 10’s or even 12’s for the higher volume at high rpm.

Maybe starting at 50% flow and ramping up to 100%

It looks like the meth nozzles are placed near the throttle valve and spray and wet down the intercooler in the manifold.
Is that correct?

The meth alone will help decrease charge intake air temps and that would really make the IC more efficient in cooling the charge intake air temps.
No way to measure unless you place a temp sensor after the IC in one of the runners.

regarding progressive, I tried it and it works well, I got some issues with going too rich at lower RPM off throttle causing shuddering and codes on defaults once I switched form CM7 to CM10 (I only have B48)

I tried to do 30 - 40 - 50 - 60 - 80 - 100 - 100 - 100 - 100

and it works well, no more shuddering but timing still same as before, also uses less meth

one question for the guys that know more about this if you set PWM too low like 30 for example is there a risk the pump may stall, or not turn at all?

Ok been having a read and got a few meth questions.

Do i need ***** before running meth or will it be ok for a while with the *** in place?
I clearly need ewg wires, but will i also need FF wires?
Does meth Only flow when in map 7?

I reckon it won’t be atomising very well at that PWN with a CM10

Will a mixture of e30 in the gas tank affect the boost with meth...? In other words would the boost be lower at the same additive with pump 91?

On Map 7 (the meth map), boost will only lower if there is a meth flow issue or if historical timing gets bad. You can read more about it here: http://www.n54tech.com/forums/showthread.php?t=22272.

Otherwise, it's fixed based on the additive you select. Adding ethanol to the tank (or running an E30 mix) should only help timing. You should not notice any ill effects, only benefits.

Now if you run a higher concentration of ethanol in the main tank, you better be running E98 in the meth tank since methanol or a 50/50 boost juice mix will strain your stock fuel system and you will run lean at too much boost.

I personally think dual CM7 is WAY too large that's why you're getting the rich fault code. Has anyone tried a single CM7?

Currently running 100% meth with e30 in the tank. I can't seem to boost more that 20 psi even if i go ADD 75. My timing is always great, peaks at 15* . Afr are well below 14:1.

You have the FF and EWG wires installed?
