Which of these are the bang for the buck?!

e-Manage Utimate
The GReddy e-manage Ultimate is as close to a stand-alone management system as you can get while maintaining the best features of a "piggy-back" engine management; an economical price, the usage of existing sensors, the ability to easily alter factory settings and not having to tune from scratch. But unlike the original e-manage, the Ultimate is more refined, requiring specific application usage (which we are constantly adding application updates that you can download FREE via greddy.com, Tech WebPages.) The benefit of this is, the included PC-based USB "Ultimate Support Tool" allows for even finer tuning capabilities, improved flexibility in fuel & ignition control and adds impressive data-logging qualities to make tuning quicker and easier. The increased number of input and output ports of the Ultimate, along with new built-in adapters add many new options to the unit. In addition to standard e-manage airflow-based adjustments, the Ultimate version includes new and upgraded features. The Parameter Set-up, tab menu format of the Ultimate has improved direct Map control for adding and subtracting Fuel and Ignition. The ability to switch between 2 preset tuning Maps (i.e. Street or Race program) via externally mounted toggle switches. There are Maps for Individual cylinder adjustment for both Fuel and Ignition. There are also options to convert injection and ignition systems (i.e. group or sequential injection and group or individual fire ignition.) An Airflow Output Map option even allows for airflow meter elimination. And when used with a wideband A/F Meter, the Air Fuel Target Map can self-tune an Injector base tuning Map, to speed up initial tuning. There are also built-in Boost, Rev and Speed Limiter-Cut features. To create super smooth operation, there are various fine tuning Correction Maps to adjust for Throttle Acceleration, Vehicle Speed, Water Temp, Intake Temp, Auto Trans Shift, Anti Engine Stall, and Idle. To further aid in tuning, e-manage Ultimate’s improved integrated Monitoring, Map Tracing and Datalogging features far exceed any other piggyback controller on the market. Even when not connected to the software, 8 channels of datalogging (at 20msec intervals) can be recorded and stored to be reviewed later. With the Support Tool connected, over 30 channels can be covered. Other new features include: Improved RPM recognition, Warning Settings, Password Protection for individual tuning Maps, NVCS (Nissan), VTEC (Honda), O2 Feed-back, Clean Fouled Plugs, and numerous others in future updates. Ideal for optimizing and fine-tuning for performance products like Exhaust, Air Intake, Intercoolers, Boost Controllers, and Turbochargers, the e-manage Ultimate fills the gaps between conventional piggyback and expensive stand-alone engine managements. All installation and tuning should only be made by a trained technician with proper air/fuel monitoring tools. (Some or all functions may not be compatible with some applications.)

e-Manage
GReddy’s e-Manage is a cost effective programmable engine management system that allows you to properly tune your factory engine control without having to change the entire factory ECU system to an expensive "stand-alone" unit or the inconvenience of sending it out for a full ECU reprogram. The e-Manage system is a true universal "piggy-back" type unit that taps into most Japanese factory ECU wiring, by utilizing the vehicle’s existing sensors (or optional upgraded sensors if factory sensors are maxed out). The major benefit is the factory ECU settings become your "Base-MAP" for tuning. There is no need for extensive tuning for normal driving conditions, but does allow the tuner to fine tune, adjust for injector changes, and add new MAP(s) for situations the factory ECU is not capable of (like on-boost conditions). And as technological breakthroughs are achieved, we offer FREE updates via our greddy.com website’s Tech page. Basic functions will allow the tuner to slightly alter factory injector duty-cycle (± 20% at 5 preset RPM points) by intercepting and altering airflow or MAP sensor signals. An option for Honda VTEC cars will allow you to even adjust the VTEC shift point. Additional features are built into the system but are only accessible through the use of the e0-1, PRofec e-01 programmer or our PC-Windows based "e-Manage Support Tool" communication software (sold separately). There is a 16x16 airflow adjustment map, a maximum 50% larger main injector correction adjustment, upgrade air flow meter adjustment, boost limiter cut, anti-engine stall, VTEC-fuel adjustment, real-time map trace, real-time display, real-time communication and basic Data-logging. 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 additional sub-injectors. If the "Optional Ignition Harness" and the software are 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 incorporate a larger airflow meter or our "Optional GReddy Pressure Sensor and Pressure Harness" to set larger scales of adjustment. All installation and tuning should only be made by a trained technician with proper air/fuel monitoring tools. (Some or all functions may not be compatible with some applications.)

CAMCON Ti CC-111, 111A, 111B
● CAMCON-Ti controls Toyota VVT-i timings and the Air to Fuel ratio.

● For any motor sports enthusiasts who never satisfy with "stock" regardless the new technology, the Power Enterprise developed CAMCON that can further advance or retard the camshaft angle with respect to the stock setting.

● It can give more crisp power response at mid-to-high rpm and also adjusted for more torque at low rpm, and in the end it achieves better gas/mileage for a given out put power.

● Over 10% mpg UP !! The effects of variable valve control improve fuel economy consequently reduced emissions.

● Actual programming to your specific vehicle with performance parts added improve more power.

Functions and Features
● Adjustment of Toyota variable valve timing within -20° ～+20° Setting is done in 1.0° increments every 500rpm from 2000rpm to 9000rpm.

● Precise adjustments of air/fuel every 500rpm between 1000rpm and 9000rpm, from +20% -10% in 1.0% increments.

● During operation, the real time display will show the Cam timing values, A/F modulation percentage or the current water temperature.

● Simply power off the Camcon Ti to return to factory default ECU calibration settings.
