I just ordered the Infinity so I'm looking forward to the gains. The tuning shop I'm taking it to says they've worked with AEM ECUs before and they say it's a massive PITA. Hopefully this one will change their minds.

I wouldn't take it this re if they say the AEM ECUs are difficult.

Good advice. Plus they don't have a dyno either so any optimization will be difficult.

If they say its a pita then they have no idea what they are doing. If you buy infinity make damn sure you goto an AEM factory trained infinity tuner

Wadzii/others,

Do you think that it is possible to effectively run a "street" NA f20c, using the PNP harness, and only the factory sensors, or does it require the additional sensors to work?

If you'd to share this information offline, please email me: matthew[d0t]leach[attttatatat]gmail.com - I need some data for an SCCA rules discussion.

Thanks,

Matt
It is totally possible.. One of the great things with the AEM stuff is that it can be run as simple as you want and you still have the option to add as many sensors, etc when you get to it.

Since the infinity does base its calculations on fuel pressure its important to have a fuel pressure gauge and a steady fuel pressure if you are not going to add a sensor. The new 300+ lph fuel pumps overload the stock regulator at low duty cycle and will make tuning a little more difficult if you dont have the fuel pressure sensor.
So are you saying that an aftermarket fuel pressure regulator and sensor is needed for Infinity?

Really? None of the AEM v1/v2/Infinity ecu's are a "PITA" or even all that complex. The V1 is kind of clunky due to the desktop software, but the V2 & Infinity are amazing and a blast to work with.

A fuel pressure sensor and regulator are not required as a static fuel pressure can be used instead on the Infinity.

However, the Infinity will not be able to make injector pulse width changes based on fuel pressure fluctuations/loss if you don't use a fuel pressure sensor.

Thanks for the explanation, even if I don't understand what any of that means. I got it in the mail the other day and I'm so tempted to install it myself but I don't want to futz it up or run a base tune right before I hit the Dragon.

Simple answer: You can just punch in your known fuel pressure to the Infinity software and not worry about adding a sensor. You have the option of adding a sensor if you want ultimate safety/control.

Finally getting it installed. Found a reputable tuner who's AEM trained. I did a baseline tune and it put down a respectable 214 at the wheels on a Dyno Dynamics. I'm still N/A w/ a Berk HFC and Super Sprint exhaust. Hoping to see some good gains with it. I'll pick it up in about 3 weeks and let y'all know the results.
