The e-Manage is miles ahead of the AFC, full 16x16 fuel and spark, it'll do many of the things a standalone will do, you won't do better for 600 bucks, but don't expect it to do all that an AEM can. The AFC is very limited.
Hmmm. . .the basic adjustments are only +/- 20% which won't do us much good with upgraded injectors without a VPC (you need at least 25% to go from 330-440 and an additional 35% if you go from 440 with a lexus afm to 550's.) Does anyone know how adjustable it is with the advanced features?
In the description on the Greddy website (which is completely worthless for the most part), it says something about using it to bypass the factory airflow meter. . .if this is the case, wouldn't this unit do the same thing as a VPC + an AFC at a fraction of the cost?
The greddy website description says:
With the use of our "Optional Injector Harness" and the software, the unit has the ability to control an additional 16x16 Injector duty cycle Map and the Controls for adding up to 2 Addional Sub-injectors. If the "Optional Ignition Harrness" and the software is used the unit has the ability to control a 16x16 Ignition Timing Map. All of the above Maps can also be Map-traced in Real-time as well. If the factory range of Map or Airflow meter is surpassed, you can incorperate our "Optional GReddy Pressure Sensor and Pressue Harness" to set larger scales of ajustment.
What does the "optional pressure sensor" do?
What's a 16x16 map?
1. The computer running the software must have the following requirements:
-Intel Pentium 166MHz processor or faster
-At least 32MB RAM (64MB recommended)
-A hard drive with at least 50MB of free space
-A SVGA monitor (800x600) and a 16bit (high color) display
-A 3.5inch 1.44MB floppy disk drive
-A CD-ROM drive
-Serial port with RS-232c D-sub 9 pin connector (male) or the use of a serial to USB adapter
2. The unit is capable of controlling injectors up to 150% larger than factory. An you will have full control over all 100% of those injectors duty cycle.
3. The pressure sensor is merely an additional signal source for the e-Manage. It does not convert that signal to speed density and it will not allow you to remove your factory airflow meter.
Actually, the pressure sensor allows you to map fuel control v.s. manifold pressure instead of throttle position. On a turbo car, throttle position isn't necessarily an indication of airflow, its always better to map fuel to manifold pressure than a throttle opening.
