Project AP1.5 S2000: Introduction, Installation of AEM Infinity & Dyno Tuning!


We gathered the three signal, two ground and one SIGNAL wire to prepare our terminals for the ECU harness side. Remember, since they are “pull to seat” connectors, slide the wires through the rubber (wire side) housing before crimping on the terminals. Then, push the terminals into the allocated pin locations (according to the pinout diagram). Once you have all of the terminals inserted, push the orange plastic (harness side) connector housing on and plug into the plug and play harness!


Now it's time to test the sensors! If you don't have gauges yet for each new sensor, you can test the sensor operation in InfinityTuner. If you get readings that make sense, you are good to go!


Now for the moment we have all been waiting for- dyno tuning! AEM engineer, Beau Brown, stopped by to tune the S2000. This is the moment that the owner/driver has been patiently waiting for after four years of ownership of this S2000 and ten constant years of ownership of S2000s.


We mentioned earlier in the article that the Infinity has almost endless capabilities. Although we don't want to list out every single function that is available (you can read them all here), we do want to highlight certain functions that are key to road racers. 

Take the example of having a racecar that typically uses E85 for competition. Let's say that racecar is in a Time Attack event with a tough battle for first place. It keeps going back and forth between first and second place with the competition, forcing the need for a lot more fuel than anticipated- a likely event in general, and could potentially happen to this project car if we take that route. Many tracks (especially in Southern California) don't have E85 pumps. Rather than frantically asking the entire paddock for extra fuel, plan ahead and have a flex fuel or multi-fuel tune (with sensor) so that pump gas can be added in a pinch.

Take another example of an SCCA racecar that is detuned to stay legal in its class, but now the driver wants to use it to run a Time Attack event where it can make as much power as the owner can afford. With four separate ignition maps and four lambda target maps available, you can get creative. 

Something else we will likely test in the future with this car is tuning for multiple boost control strategies. Believe it or not, having full boost at all times throughout the track isn't always ideal. Different levels of boost can be tuned according to things such as gear selection, wheel speed, or even switch based. Take it one step further, and a four-stage nitrous control will available in the near future for the Infinity. Mental note taken!
