Checking out some of the fuel alternatives. The MAP ECU offered from cork sport removes the MAF. The E-Manage I do not believe does. What is your opinion on using this and another unit to control ignition compared to using a stand-alone EMS costing near or more then double after tuning expenses.

From cork sport at $650.00
The MAP-ECU (Manifold Absolute Pressure Electronic Control Unit) is designed to provide two main functions:

* Removal of the stock air flow meter (hotwire, flap, and Karman-Vortex style) and conversion to speed-density (MAP) based tuning.
* Complete control over your OEM ECM fuel table by tuning the air flow signal traveling to the ECM, allowing you to install larger injectors, forced induction, or other major engine modifications.

The MAP-ECU will work on any late model fuel injected vehicle using most major types of air metering systems (hotwire, flap, and Karman-Vortex) found in use today. It can be installed on any 1-16 cylinder engine in less than an hour, and completely replaces the restrictive factory air meter. The benefits include:

* More horsepower and torque by removal of the restrictive factory air meter.
* The ability to use the stock ECM to control larger fuel injectors and/or performance upgrades
* Retains the daily driveability of the stock ECM usually sacrificed with a full aftermarket engine management upgrade.
* Built-in manifold pressure sensor capable of reading up to 30 PSI boost pressure.
* Real-time tuning using Windows® based MAP-CAL software supplied with the unit.
* High-resolution 374 point table (0-8000 RPM and -10 to 30 PSI) allows fine tuning for performance and driveability.
* Built-in display and logging of key engine parameters such as RPM, Throttle Position, Boost Pressure, and Airflow.
* On-board support for display and logging of popular aftermarket wideband Lambda sensors/controllers.
* On-board programmable NOS window activation switch can also be used to turn on other accessories at set RPM/PSI points.
* Simple piggy-back installation only requires 5 wires to operate with no major re-wiring of OEM components.

CorkSport is working on premade fuel maps for Mazda vehicles. If you would like to purchase a unit we can provide a base map if it is available.

The only thing about the MAP ECU is, for a few dollars more, you can have a standalone. The MAP ECU is just a piggyback on steroids, and is basically just a MAFT.

Thx Rat.

I came across a ignition manager a wile ago but do not remember what one it was, so price I am not able to give. I was thinking 650 + however much for the ignition might be worth it. Maybe not. I have to consider I have looked within 2 to 2.5hrs of my location and the only tuner is one for jet chips and the nearest 2hr away dyno charges 100$ a single run. Thinking with a base map some ? on here and a wide band AFR I may be able to do the fuel myself.

That very well may be true, but for 650, the MAP ecu is not going to allow you to do anything that the SAFC will not allow you to do EXCEPT (and this is a big point here), it allows you to ditch the AFM. With the ignition controller I would guess that it would guess price would get pushed to well over a grand, which puts you WELL into the range of Haltech/Microtech prices.

Tuning ISNT rocket science, its all about AFRs and timing. The fact is, there are countless maps available for the E6 series Haltech ECUs.

I am not trying to bash on the MAP ECU, I have a friend that swears by them, but in my opinion, its not a cost effective mod, when a full standalone can be had for a few dollars more.

Thx for the NFO. I have to agree myself if it comes within a few hundred $ from a stand alone that it would be best to save the few penny’s and get one.

I am sure I am thinking beyond the project GTU scope necessary realisty. I really like the idea of ditching that MAF. But I do not see that car ever going beyond a stage 3BNR or even 350BHP within 5yrs or longer unless she really gets into the car and puts money into it. Personally she rather spends money ells ware first that’s why I say that. So maybe just a SAFC and some ignition retard with injectors would be more then enough for the project. But I am not a EFI programmer to know.

Do not ,i repeat donot get the map ecu, i bought one for my rx7, now mind u mines supercharged with nos , my car spent three months in the shop because of that peace of **** ecu, there ******* tech support sucks , we had to creat out own base line map, dont do it man, if i knew what i new now i take thoses mother ******* to court, the map ecu is not condusive to rotary engines, save your money and get a stand alone....!!! **** map ecu and the horse they rode in on, if it seems im pissed i am. i spent lots of money on time labor , and got **** to show for it, soooooo if i can save one person from getting that peace of **** ecu , its all worth the raging ur reading here.sorry for the bad rap , but man you dont wanna get that for your car , beleave me. its not worth it. rx7fromcal
