Wiring harness and the Holley Commander 950
|
The tuning power of the Holley Commander 950 has just jumped to the next level. The PRO software is available now. This is our most popular engine management system with over 260 units currently installed on Northstar engines ('93-'99). This unit now has been modified to control the 3800 Series II and III Supercharged engine! The new software program offers the following new features;
This new software is a must for all street driven cars. The older Commander software can operate in closed loop, but the air/fuel ratio is standardized at 14.7 (narrow band O2 sensor). The new PRO softwart allows the user to program a richer A/F for the performance engine modifacitations. We will offer the wide band O2 kit that will plug into your exhisting harness. Your ecu box will have to be sent back to CHRF for reprogramming to accept the new software. We have started to manufacture our own controller and wiring harness for the guys that want a plug-in and play system. The unit consists of the Holley Commander 950 that has been modified to address the Northstar crank trigger timing sensors. It uses and plugs into all of the existing sensors on the engine including the stock coil pack. Timing and fuel delivery are easily changed with the supplied software and your laptop computer. It does come with one of our programs installed, but fine tuning to your application is required. Don't worry, it's easy and should only take 1 hour to install!
The Electromotive HPV-1 system controls the ignition only. These units are used with the carburated engines. You can preset the initial advance for idle quality (approximately 10 degrees for the stock Northstar), add from 6 to 25 degrees to the initial advance up to 3000 rpm, a decrease or increase of up to 10 degrees on a line from 3000 rpm to 8000 rpm, and there is also a soft rev limiter built in. The Electromotive systems requires you to install an ignition timing wheel. Two styles are available; crank shaft mount and camshaft mount. I gang the camshaft wheel behind the water pump wheel on the left side intake cam on most of my engines.
Electromotive Tec 3 This is a great system, but the wiring harness does not come with sensor plug-ins! It takes a lot of your time to make up these ends.
