Well i have had my Apexi S-AFC II sitting in my bedroom for over 6 months as i have not had the time to install it as i have been busy with other things with the Z. eg replacing the transmission i blew :x now i'm unsure whether to install it as i dont know if my new trans mission will blow up on me again (was running 12psi) so i have wound it back to 10 as i dont want this event to occur again :`( anyhoo my question is if i install the AFC will this fix up my "bad" fuel maps that i saw from the dyno.. when i am just driving the car normally as i am getting very poor fuel consumption 16-17L/100k's. So if its tuned properly will it make this better??
Have you checked your O2 Sensors? Also did y ou consider getting your transmission built in a way so it can handle high HP? I think one of my friends got his done and was running 13psi + nos and he never had problems with it after he got it rebuilt. Not sure what they did though.. maybe speak to WYKKED about what you can do to toughen it up?
Yes it will... you can virtually make the air/fuel graph the way you want it to look, removing lean and rich spots and basically make it a nice straight curve in the desired ratio for max power. You can also tune the narrow throttle mixture for max economy. You just need someone to tune it that knows what they are doing - its really not that hard once you have a dyno. I tuned mine in around half an hour and I've done a few hondas too except its a bit more involved selecting the ideal VTEC engamement point. The best method is to set the APexi NE points to the same as the dyno increment for ease of tuning. For example NE points would be: 0-500 500-1000 1000-1500 1500-2000 2000-2500 2500-3000 3000-3500 etc up to 7500(7500+) You then set the dyno dynamics bottom scale to read 500 RPM increments as above. Then its as simple as doing a baseline ramp run and adjust the +/- Fuel correction for the RPM ranges untill you get the desired a/f ratio per increment. It really should'nt take more than around 10 runs to get it right. Once the curve is flat or linear depending on tuners preference you can move the whole a/f map up or down to see which A/F ratio's your engine prefers(ie some engines will make more power at slightly leaner mixtures than others and vice versa. APC tune these all the time and are quite good at it, but Colin Brodie also has a brand new dyno and I'm sure he'd give you a good deal. Hope this helps. Catcha
