|  4Bar map
Hello I want to buy a progressive kit to injec alcohol when the map senses more boost, the problem is that I have a 4bar (40+psi) map and seems like I can only buy the 3bar Progressive Controller, so how can I cover all the boost range with alcohol ? Thanks. |

The controller is simply based on a voltage scale. The 3 bar and voltage controller are the same, 1.8V to 5v. If your sensor is in that range for the boost you want to activate it at then it will work for you. Some 4bars read the lower voltage in mv's like .046 .048 ect. The controller cannot read these. You would have to check your voltage at idle.

mmm thats the problem, I am using Megasquirt and as you may know Megasquirt uses an internal Map sensor, and Im not sure If I can get the 0-5volts signal to activate the WI kit :( Does somebody knows how can I get that signal upon the map readings?.... Or any external 4bar map with 0-5v output ?. Any Megasquirt users here? |

I believe the 2 options would be 1. solder the wire to the output pin on the megsquirt or just run a gm 3 bar map sensor for the devilsown controller. They are just alot cheaper than 3.5 or 5 bar aem map sensors everyone runs.

Yeah.. that will be prolly my best option .... Ok, I want the progressive kit for my application, is the same as the universal stage 2 kit that is in the online store?? I think it does not include the 3bar map sensor, so how much will be including shipping to 90650? |
