Progressive Min and Max settings on Big Turbo

[bstock1990]

Hello just needed some inputs on min and max settings that you guys are running?
Im using the coolingmist CMGS kit with 250 psi pump m10 nozzle
on a 50 trim setup...

i have minimum once boost kicks in and maximum around 25-30ish....im running 24 psi on a 50trim. you can raise/lower the maximum to "tune" how rich or lean you want it to run w/ the meth.

which Vari-cool do you have? Vari-Cool II or Classic Vari-Cool?

you should never turn your max knob higher than your max boost. If you have the VC2 you look at the user document under 5.1 and set the MAX dutycycle instead. By default its 100%. If you need less flow, you can adjust it down. For example, if you set it 70%, when you hit your MAX boost the VC2 / CMGS will scale the entire range of flow over the entire min/max boost range.

you can also set the MAX dutycycle with the classic varicool using the software OR you can set the tune knob. The tune knob will lower the Max dutycycle by 7.5 % each time you lower the tune knob. 10=100%, 9=92.5%, 8=85%, etc.

Hope that helps.

Hey David its Chris from France just got the kit running last night put the M10 nozzle in and it seems to be running very rich 9.0 A/F

im not to sure how i should have my settings for the min and max
right now my min is at 15 and max 26 which is my highest boost

should i change the duty cycle on CMGS2?

also i noticed that flow bars start to light up before 15 psi is reach is that normal?and sometimes when im at partial throtle and im building boost and will let off the trhottle quickly they also flash as well?

I remember telling you when you ordered that M10 is too big. 250 psi pump + M10 =1200 CC/M. I recommend using a smaller nozzle.

the flow bars cannot light up until it starts flowing. Maybe its happening so fast that you cant get a clear picture. If your min was not reached, it would not be flowing, flow bars would not be lit.
