Can you explain to us abut the s-afc your experience whit this elcetrical tool ,Y read that made to you something like 5 hp in your power band ,it pretty impressive .How it works ?How can you monitired the flow ?its esy to install ?how much it cost in EEUU? .Thanks

It is fairly easy to install and its a cool little gadget...First what it does it reads my MAF sensor and the AFC tricks the ECU by sending false info, basically what I set it to be... If I input +5% at 3,000RPM at full throttle then at 3,000 RPM my MAF would read like 15% but the AFC would send to the ECU 20%, therefore the ECU compensates for the increased airflow by changing the amount of fuel to mix...anyways...the AFC reads real-time REV,AirFlow,Throttle position and correction...it also has some other kewl little things but its all for looks...anyways hope this helps and isn't so confusing...

So the Apex'i only works are WOT (wide open throttle)?

[ty423]

No....You could though.....ok the AFC has a SETTINGS function...You change the airflow correction percentage for both high throttle and low throttle....and there is another setting to set how much high throttle is and low throttle is.....Mine I didn't mess with and I think my high throttle is like 70% and my low throttle is 20% something like that...so when the AFC reads 70% throttle open then it uses the high throttle settings...and something like that....its kinda weird and am still trying to figure out....If I am wrong about this please correct me cuz this is what it seems like...

Ok then that's not to bad then. I though the AFC would apply the percentage across the entire throttle range.

I'm pretty interested in this because if JWT doesn't get the ECU out before next spring I'll get the Apex'i AFC and go-a-dyno-tuning. It will give me something to tweek while I wait for the JWT ECU.
