Provides standalone management of air/fuel mixture onvehicles with frequency based MAF systems. This Mini-AFC allows adjustments to MAF(Mass Air Flow ) frequency signal (in Hz) from 1 to 255% of original frequency in 1%increments. This allows the operator to lean out or richen the Air Fuel mixture simply bychanging the digital DIP switch settings on the device. The AFC adjustment is applied to the entire MAF operation range. The AFC checks switch settings on power up and applies them immediately. Changes to the switches will not result in a % change until the unit is powered down and then back up again.

This is a way to be able to fine tune your cars Air/Fuel ratio without owning an expensive tuning software. ALSO, its main use now-a-days is for cars that are maxing the stock MAF sensor chart which is 11,500 hz. But if that is the case, the PCM MAF chart must be modified to compensate for the amount removed in the AFC. This is an adjustable version of our Fixed Frequency Mini AFC.

Basic MAF chart modification:

  • Take 100 and divide it by the number that you enter in the MiniAFC, then multiply that result by itself two more times. The end result you will use to multiply the entire MAF chart by.
  • For example, set the MiniAFC to 90% and then multiply the entire PCM's MAF chart by 1.372 

3 to 3 wire is for 97-03 Grand Prix and 97-05 Monte Carlo/Impala/Regal/Bonneville 3800 cars.

3 to 5 wire is for the above cars that switched over to a LQ4 MAF sensor.

5 to 5 wire is for 04-06 Grand Prix only with stock MAF sensors.

maf adapter w/ ait plug

it hasen't been completely tuned yet, so it is just too soon to say.

Great for fine tuning

If you need to richen up your air fuel ratio just a bit when you do a 3.6 or maybe even a 3.5 pulley, this will add enough fuel to do the job providing you have all the other supporting mods. Just keep an eye on the LTFTs at power enrichment. A full tune is ideal but this device is at least a simple way to richen up th AF ratio to diminish KR

Simple, quick and effective

Recieved the controller sooner than expected, as is usual with Zzp. If you wear glasses you'll need them, the dip switches and the numerals printed on the board are tiny and I wish the leads were a longer to give you more of options where to put it. It works as advertised

Awsome If It Doesn't Fail On You

Another Exspensive Item But Worth It If Your Going Turbo With Your 3800. I Got Mine Set To 82% And Tunner Was Able To Tune It No Problem. Stock MAF Maxes Out Really Soon ~10 PSI On A Small Turbo Blow Through Set Up. The Switches Do Adjust Your MAF Reading Linearly. This Is Great With Being Able To Adjust It Because Over Time My AFR Has Changed Since I Got It Tuned And I Was Able To Dial My AFR At WOT Back To 11.5. I Need A ReTune But Having This Allows You To Make Slight Adjustments To Keep It Safe At WOT. Also 1% Change On This Corresponded To 0.2 AFR Change On My Car At WOT. When Car Was Tuned It Was At 82% A Year Ago. I'm Now At 89%.(I Raised My Boost.Higher Than What It Was Tuned For) But Will Set It Back To 82 And Get ReTuned. The Only Issue I Had Was Warranty Through Easy Performance. I Had A Failure With Mine And Long Story Short They Said There Was An Issue With My Vehicle Wiring Not Thier Product. I Had To Send It In 4 Time Before They Finally Figured Out What Was Wrong And Fix It. I Had To Buy Another And Prove To.Easy Performance That It Wasn't My Vehicle Wiring. now I Have One As A Spare. Overall Great Product.
