Just ordered an EFIE - BrightGreen FeverBuster
Just ordered the 'FeverBuster-A' from BrightGreen Inc.
Electronic Fuel Injection Enhancer (EFIE) https://www.brightgreen.us/feverbus.htm Wondering who else here has or is running a similar device? How did it work leaning out the car? Any substantial increase in fuel economy? Any negatives? I am traveling into unknown territory! :) Any tips? I will post my results in this thread. Another popular one I found was Eagle Research's. Available as plans or preassembled. https://www.eagle-research.com/store/...8f67f8671dc540 |
I've used the Eagle Research EFIE...have one in my truck to test when I get some other things done to it....like the odometer fixed. :D
All I can say is that you have to let the ECU adjust to the change...it's not an on/off kind of deal. Make gradual changes. Be sure you connect it right. You should gain some mpg from using one alone, but they are mainly meant to be used along with other mods like fuel heat or acetone. But each car will act differently. If you have a scangauge...it will be easier to tweak. |

Just got back from a business trip and the EFIE was waiting for me at home. Hopefully, I will install it Sun/Mon. I was also looking at heating the fuel...one step at a time. ;) |

Air/Fuel Ratio (AFR) Gauge Online ... https://www.gassavers.org/showthread.php?t=4741 I know the EFIE works because I can see the AFR go lean, and I can feel the engine lose power. However, it looks like you won't notice a difference on your scangauge : Civic HX and Scanguage? https://www.gassavers.org/showthread.php?t=4940 Which has a URL link to here : Re: New SG Firmware Thread. https://www.cleanmpg.com/forums/showp...65&postcount=8 Quote:

The Eagle Research's is 60.00... https://www.eagle-research.com/store/...d7b6495dee66b2 The similar FeverBuster-B is 93.00 I purchased the FeverBuster-A for 155.00 https://www.brightgreen.us/orders.htm After talking with the owners of BrightGreen (small family company), I was sold by their assurance of a higher quality product and opted for the 'A' Model with the on/off switch already built in.

Does anyone have any time/mileage gaslog, which reflects a before/after value for any mileage improvements from using one of these devices?

EDIT : *IF* it did work as originally expected, I could predict and test for fuel savings based on the new AF ratio. I need to get my butt in gear and publish my installation. CarloSW2 |

No. You DON'T want to try adjusting it while driving. Don't ask how I know. The ER EFIE has been redesigned...new board. I'd put the board in a small plastic box. I think the FeverBuster is more for '96 and later cars. Not sure I'd pay extra for a switch though...since they work by slowly being adjusted to the ECU....once tweaked...you'd want to leave them alone? I think the FeverBuster tweaking instructions make more sense though....start low and work up? Where as ER says to start around 300 mvs. I have limited experience with one car (ER EFIE) and ended up adjusting it to around 200 mvs or so....anything above this caused poor running starting out cold. The FeverBuster idea of using a vac gauge to adjust it is something I'll have to try. |
