Installed a Greddy E-manage last weekend, all settings on zero, and no maps loaded.

Took the car for a few spins with a laptop hooked up, and recorded some data.

To view the attached file, d/l Greddy Support Tool and update it with the latest firmware (V1.49)from http://www.mohdparts.com/emanage/#E-manage%20Software%20&%20Firmware

Go to "Data Analysis" and load the file.

First part is cruising at 100k's, then a 1st, 2nd, 3rd hard acceleration run.

Everything seems normal until engine gets to 4,000RPM. At that point, the E-manage appears to output a different Airflow reading to the one it's receiving from the Meter.(the Yellow line)

Car runs fine. Can't tell if it's extra lean or rich without an A/F meter, but I would have thought the E-manage would make no adjustments until you start loading maps.

Any observations?

EDIT- Can't attach file : invalid? Here's a screenshot

I would think at zero state it would do nothing as well
My e-manage is sitting at zero state too

When will you be getting it tuned?
Also, is this the voltage from the o2 sensor?
If so I think as with most voltage output sensors it would run on 0.5v-5v or so?
I assume 5v would be the richest, so if the e-manage is producing a higher output voltage than it's getting it would mean that it's telling the ECU it's running rich and therefore ECU would lean it.
And vice versa

Where the black dotted line is on this one, you can see the "Total Airflow adjust" is on zero, and the Airflow in and out are the same values (expressed as a Frequency reading from the MAF Sensor in Hertz)

This is at almost 4KRPM. After this point, the airflow adjust goes into negative values, with a simultaneous change in the "in " Versus "out" readings, peaking at -20 like the first screenshot. It then does the same for the next gear.

There's no O2 sensor connected to the E-manage. I think you can only connect a Wideband O2 Sensor, via the MAP Sensor input, but I'm planning on getting an Innovate LM-1 Wideband Kit, which has a separate display for linear O2 readings, rather than the "Too rich, too lean , perfect" output that the standard O2 sensor gives.

Will get it tuned after the heads and extractors are in, but just wanted to see the feedback from a stock engine.:D
