Fast EFI system with 4 stage nitrous control, wideband O2, and individual cylinder spark and fuel control. Not XFI - it is the original Fast ECU. Wideband O2 senso is included. No harness included with system, but still available through FAST. Original part number 30-213211. I purchased this unit from a former FAST employee but I have to put my project on hold because of finances. I was told unlike other fast ecu's of this type it will work with any NTKL1H1 or L2H2 wideband sensor. Replacement sensors do not need to be purchased through Fast. I paid 975.00 2 months ago and i would just like to get what i paid back out of it. E-mail me with any questions.
