I was doing some thinking today, When I was stationed in Japan I had a Nissan Silvia with an SR20 turbo engine and I used an Apexi Super AFC for tuning (http://www.apexi-usa.com/product_electronics_detail.asp?id=202&pageNum=1)
Anyone who has used one of these before will be able to tell you how great a tool these are. They measure and display air flow readings, rpm, vehicle speed, injector duty cycle, and a multitude of others. They also allow for changing the injector sizes and readjusting the flow as neccesary. The super AFC is not completely universal, however there is a possibility that the sensor on our engine may be compatible. I was wondering if anyone knew the exact type of air measurement this car uses? I am not sure if it is speed density or manifold absolute pressure. Depending on which I could find out if it is compatable or not. Another issue is the AFC needs a throttle input, on my 06 Reno I have an electronic throttle so, I am not sure if I would have to find a way to electronically reconfigure an output voltage in order for it to read correctly. On my Silvia it was 0v closed and +5v fully open, I will have to check this. Anyone know where I can get an ECU pin diagram and does anyone know what type of aiflow sensor we use? I am sure that this would make a fairly decent horsepower gain with a good tune on the peoples cars with intake and exhaust mods. Of course we would need to use a wideband 02 sensor to make a good tune with. Anyway just a thought I had that I would like to try out. Toss me some input :grin:
