Got an emanage recently and was just wondering if there were any tunes previous users have made for use with bolt-ons? So far I have a short ram intake, warpspeed y pipe, and a full custom 2.5 inch exhaust. I have basically no experience with tuning software but any help would be greatly appreciated while I take the time to learn how to use it.

 

You're going to need a wideband A/F meter (additional O2 sensor) and connect it to the EMU for datalogging purposes and tuning.

Or, after you install the EMU, let a professional shop tune it for you. You remove the cat and install a test pipe, then the shop can get decent A/F trim readings from the tailpipe and tune accordingly on the dyno.

When I tuned my Maxima, I installed a wideband A/F meter and additional O2 sensor in my headers, then proceeded to let a professional tuner tune it on the dyno and the street. Tuning is way over my skill set.

 

Definitely get a wideband that will work with the EMU.

Have you got the software connected and up and running? Have you looked at DandyMax's setup instructions?

Compared to other tuning solutions I felt like the only tricky part (once it's up and running) about tuning with the EMU was raising the redline.

You should also get ECU talk or some other laptop based logging solution for the factory ECU. Logging the EMU won't give you that.

My opinion for order of operations while tuning is: start with at least new pre-cat O2 sensors and known good fuel pressure, then adjust fueling so all non-WOT long term fuel trims are as close to 100% as you can get. THEN move onto WOT logging and tuning with the EMU.

If any of that doesn't make sense, start searching and reading, take your time, make small adjustments, log, repeat.
