APEXi 401-A018 AFC Neo Fuel Management System

I used this on my IS300 I turbocharged (5 psi with 330cc supra injectors and walbro 255). So far it's working very well, I have to dial in my idle as it's not perfect but my AFR's are good all across the revs. Overall I'm impressed. My ECU is in the engine bay and the wires are really easy to access so I opted to wire it in myself. The install is super easy, so I wouldn't necessarily recommend a plug and play harness if you're mechanically/electronically inclined. It might be awkward for those with ECU's in cramped locations. I have an AEM wideband gauge hooked up, and as you adjust the fuel map on the Neo, the gauge responds instantly.Long term update: I used this reliably for about 1000 miles then upgraded to a standalone ecu. The difference is night and day. Yes this worked for me at low boost, but I can't attest to its longevity or its limitations at higher boost.

Awesome product!!! Works well with tuning my Mines ECU for my 97 Toyota supra. The Mines ECU is notorious for leaning out the car too much. The AFC helps to add fuel in order to even things out. The graphical display is a tuners dream as one can easily set the timing as well as how much fuel enters the engine at various RPM ranges. Keep in mind though that you should get a professional to install since instructions are in Japanese.

I chose to get this to tune my 1998 GS300 JDM 2JZGTE VVTi single turbo with 4 speed automatic. Does every thing it is suppose to do! Dyno tune with it and made over 420+ ft lbs tq. and getting @ 18-20mpgDelivered earlier than expected. @7-9 wire to wire up. Very easy!

All of the instructions are in Japanese now I need a translator what doesn't make any sense is the product reads in English and all the instructions are in Japanese

Did what I expected it to do, gave me a cool Oled gauge.
