If you want a progressive feature on your car then get a controller that works off of a 0-5 volt signal and pull your signal off the MAF. Just trying to help here.

Really. GM mass air meters don't send a 0-5 volt signal back to the computer? Then how do they work? And why have I used this signal to work with our controllers countless times? Also, how is it I have had customers use the LS1 mass air on their 3800 engine by using a 3 to 5 pin adapter pigtail?

GM MAF sensors produces a frequency signal they do not output a zero to 5 volt signal, How do you not not no that. How do you think the AFC works on these? Looks like you need to do a bit more reading.

use a "coldwire" MAF system (produced by AC Delco) where the inductance of a tiny sensor changes with the air mass flow over that sensor. The sensor is part of an oscillator circuit whose oscillation frequency changes with sensor inductance; hence the frequency is related to the amount of air (cubic feet per minute) passing over the unit. This oscillating electrical signal is then fed to the car's ECU. These MAF units (such as the one pictured) have 3 pins, denoted +, - and F. F carries the square-wave frequency between - and F. They are powered by +5 VDC from the ECU's regulated power supply.

Your not only giving our customers wrong information your on our forum. How do you not know how a GM MAF sensor works vs a MAP sensor is beyond me.

We should ban you just on you giving people the wrong info.

I suggest people here stick to the guys that know Grand Prixs like the back of there hand. We did run the OK GP Club for years and had over 200 members back in the day.

The MAF doesn't give off a 12 volt signal back to the ECU.

Ask them not me.

Why do you think we commented on the nerve of you to get on here. Duh!

I know you guys banned me. Which if you ask me I think is the easy way out of not dealing with the questions or comments I made.

I never called anyone names as your doing here. Since your going to call me names I figured it only fair to respond. If you look back through my posts. My first post was "you are Devils Own" or something along those lines. I had no idea Chance started this site. As I mentioned someone posted a link on this forum which when someone clicked on it and was redirected to our site we received a notification through our web tracking software.

Reading through a post I recognized the screen name 468Rocket as Chance from Devils Own. Just curious why he would act like someone else. I guess he didn't want to answer that question. Just as you don't want to comment on the nozzle post I made and why we have the same nozzle as you guys. Why did you stick that company with thousands of dollars worth of nozzles you agreed to buying? He's going around calling me dirty. It business so get over it. I didn't stiff a company for thousands of dollars worth of nozzles.

By the way Rodney how about you learn how a GM MAF works before giving people advise. They output Frequency not voltage. Very scary you don't know that. You guys should stick with the Grand Prix experts that are the actual vendors on the site.

You must be confused. I've ran a lot of our controllers on GM MAF's I can't speak about your controller because I don't know anything about it MAF function. I was just explaining that to use a boost signal on a roots supercharger or twin screw is really no better then using a on off boost switch.

I wouldn't have any of my twin screw or roots style supercharger customers use a boost signal is they wanted to get a progressive feature. You a MAF signal instead .

Really, how did a controller that reads a 0-5v output translate the frequency output of a GM MAF sensor, It will only work if it has a MAF frequency table but you know that right since you have done a lot. The controller you use does not have a MAF feature there for the boost port must be used.

You obviously are confused with other vehicles, Ford does a 0-5V Honda plus pretty much all imports do as well but not GM. They never have and probably never will.

Man that is sad. I feel bad for those customers you told that it was a voltage output source.
