So im tired of my MAF freaking out and dealing with it. So I was wondering if there is any sr20det redtops out there running this piggy back map ecu...it just takes the hot wire maf signal to a piggyback box that is a 3 bar map that tells your ecu. You are able to tune fuel and timing. The map ecu2 has a lot more stuff it is able to do. the map ecu1 is 425.00 and the mapecu2 is 725 almost like a complete standalone but not. Anybody trying it.

The MAP-ECU2 replaces voltage and frequency based air flow meters with Manifold Absolute Pressure (MAP) based load sensing (Speed Density). Voltage types include the spring door flap and hot wire types used by numerous manufactures. Frequency based units are commonly known as Karman Vortex Frequency air flow meter as used by Mitsubishi™ or DSM vehicles and some other manufacturers.

This MAP-ECU2 combines the functionality of other manufacturers Air Flow Converters and Vane to Pressure Converters into the one unit, plus more. It is supplied with a blank table for professional engine tuners who have the experience to customise the configuration. Many base tables are available for popular vehicles. The MAP-ECU2 tables are programmed using a 2D Table Mode or the 3D Graph Mode. Both views allow real-time editing of the MAP-ECU2 Fuel, Timing, Auxiliary Injector and O2 Adjust configuration.

The MAP-ECU2 combines the functionality of the MAP-ECU with full Timing control, OEM Air/Fuel Ratio Adjust, Auxiliary Injector control and Electronic Boost Control (requires the purchase of the Powerhouse Racing MAP ECU2 Boost Solenoid Kit on this page).
It also has many on-board functions that usually require the purchase of secondary piggyback controllers such as:

• Launch Control (2-step Rev Limiter)
• Fuel Cut Defender (a.k.a. Boost Cut Controller)
• Speed Cut Defender
• Speed Adjust
• Nitrous Control
• RPM Switch
• Pressure Switch

The MAP-ECU2 has a built in serial port which is connected to an Industry Standard PC running Microsoft(™) Windows2000(™) or WindowsXP(™).

Configuration and monitoring is accomplished using MAP ECU's proprietary graphical user interface. The graphical user interface allows real-time configuration and monitoring of the MAP-ECU, even while running the vehicle on a Dyno, etc.

MSRP $849.00 Your Price $725.00

 

For $725, I'd be looking for a used PowerFC D-Jetro. Those map-to-maf converters aren't the right way to go. I know the calculation, and you need to know what you VE is at every point you want to tune to. Plus now you're tuning on top of tuning.

I'd just spend the day and a fraction of the money to take it to a shop that can just fix your maf sensor. Take to S&R and you can probably get Enthalpy to tune your ROM in person while you're there.

 

its just that im on a napa maf that blows and im tired of spending the nissan oem price for one. The one i was looking at was 425 and that just does fuel and timing.

Plus they have a forum in the TR Shops section. OEM used Z32 mafs go for $75 in the for sale section here. Spray them out with CRC MAF Sensor Cleaner, and you're good to go.
