The Haltech is now a PNP unit that comes with a base map and has a built in 3 bar map sensor or optional 4bar for just an extra $30. And I'm sure once you go with the Haltech you will never have to PAY for updates or revisions, Just simply download the updates/firmware. At the moment I'm torn between the pnp Haltech E8, AEM and Apex PowerFC.

Harness the power and flexibility of the Haltech E8 in a simple-to-install plug-and-play system for the Toyota MR2 and Celica All-trac! The plug-and-play interface box comes prewired for your application for 1990-1998 USDM and JDM models (please specify your application in the order comments section, we'll preconfigure the internal jumpers for your wiring setup).
The Haltech E8 is packed with more features than any ECU in its class by more than just a quarter mile. The all new E8 performance ECU is for those who are on a budget and need full sequential control for their engine.
The Haltech E8 ECU is an ECU capable of controlling sequential injection on 2 and 4 cylinder with semi sequential 6 and 8 cylinder applications. With 8 channels capable of controlling injection and ignition duties, the E8 can support most modern engines with multi-coil ignition systems, as well as conventional distributor ignition systems.In addition to controlling fuel and spark, the E8 can control various auxiliary engine functions.
* Stepper motor and BAC/IAC closed loop Idle Control
* Closed loop boost control
* Soft cut rev limiter
* Tuning via TPS with Manifold pressure correction - Ideal for those multi-throttle body
turbo cars such as, GTiR Pulsars and GTR Skylines.
* O2 sensor closed loop mixture control
* 32x32 mapping structure
* On board data logging (up to 200 samples per second)
* User definable mapping points
* Numerous correction maps to ensure smooth drivability under varying operating conditions
* Windows Software
* The ability to calibrate just about any sensor for OEM applications and of course all the usual outputs you would expect to find in a Haltech engine management system.

Typical Applications:
* Control of fuel injection on modified engines
* Conversion from carburetion to fuel injection
* Race and rally applications of all description
* Design and development purposes
* Educational use by universities and technical colleges
* Original equipment in cars and motorcycles
The E8 includes:
ECU Programmable Computer, Programming Cable, Programming CD, Instruction Manual (on CD).
The MR2 PNP application adds:
* 3SGTE plug and play wiring harness
* Built-in 3-bar MAP sensor and included MAT sensor to convert to speed-density and get rid of the factory AFM. (4-bar sensor optional) -$30.
* 3SGTE base map*
