Hi,
I'd like to share some exciting news with y'all. In about 8 weeks, a new product is going to be launched that will hopefully make tuning big HP cars with RETURNLESS fuel systems a less daunting task.
The product is called the Afterburner-eFPC or "electronic Fuel Pressure Controller". It is basically a serial-tunable, electronic fuel pressure regulator (fuel management unit) for RETURNLESS fuel systems.
The Afterburner-eFPC allows the user to create maps of fuel pressure versus engine speed and throttle position. The adjustments can be made in 1% increments, in 400rpm intervals from idle to redline (200-10,200rpm).
There are two maps in the "Stage1" device, one for part-throttle cruise situations and the other for WOT conditions.
The "Stage2" device has the capability to store two separate tunes (i.e. 4 tables).
The "Stage3" device has the same capabilities as the Stage2 product but also has a nitrous solenoid driver controlled by an internal "window" switch, WOT switch, and fuel pressure sensing switch. Therefore, this kit can be used to provide super safe fuel enrichment for dry nitrous kits without additional peripherals.
The "Stage4" device, which will be released next spring, will have an auxiliary input for monitoring boost level and the user will be able to create maps of FP vs. RPM/WOT or FP vs. BOOST. The "Stage3" kit will make use of a 2 or 3-bar GM-style MAP sensor. This is similar in functionality to a classical FMU but much more accurate and flexible AND designed specifically for the RETURNLESS-style fuel system.
This product is currently under beta test. Stage1 and Stage2 product releases should be sometime in November. Stage3 and Stage4 devices will be released in Spring of 2003. Hopefully, this device will help tuners tame the RETURNLESS fuel system.
Just so you can get an idea of the results possible with this device, check out this dynograph where I tuned my '03 Cobra with 2.93" pulley. The blue line is stock tune and the red line is after tuning with the Afterburner-eFPC: http://www.svtperformance.com/forums/showthread.php?s=&threadid=16763
