SimonR Posted August 8, 2005 Share Posted August 8, 2005 I'm trying to get my head around how an Emanage works so that I can tune it myself (bigs mods on the way) and I've been reading here and on the Yahoo groups. I've got the support tool and have ordered the special USB cable. There are some bits I'm not quite clear on. Can anyone help? Controlling AFR seems fundamental so a wideband sensor looks like an essential. Can I get a feed from a sensor to the Emanage and, if so, can I log the AFR against the throttle setting and the RPM? If not, is it just a question of watching an AFR gauge in the cabin while making a mental note of the RPM and throttle position? Any suggestions for a gauge/sensor other than the AEM (which seems a bit pricey)? I've got the Emanage pressure sensor installed. Will this allow me to log boost pressure to the Emanage as well? To be more precise, will it allow me to log boost pressure along with AFR (assuming that I can log AFR, of course), RPM and throttle position? Apologies if these have been covered before. I did look but couldn't see. Quote Link to comment Share on other sites More sharing options...
JustGav Posted August 8, 2005 Share Posted August 8, 2005 Which emanage do you.. The ultimate has got two option inputs, whereas the gold/blue only has the one which is usually used for boost. Gav Quote Link to comment Share on other sites More sharing options...

JustGav Posted August 8, 2005 Share Posted August 8, 2005 You will be able to wire the boost sensor in, and use the AFR meter on the second Airflow input, you will require some additional software to log it, if memory serves me correctly.

SimonB Posted August 8, 2005 Share Posted August 8, 2005 You can log AFR, but it's not all that straighforward. What you do is wire your AFR into the 2nd airflow input on the Emanage that is normally used for Skylines etc that have two airflow meters. Normally the support tool won't let you log the 2nd input. You can either trick the support tool into allowing it to be logged, or use a third party bit of software to do the logging. Tricking the support tool involves hacking the map file which is a bit dodgy and then you have to convert the support tool logfiles into CSV that you can import into Excel. The easier thing to do is to use a utility called "emm" which you can find on the Yahoo group under files. That logs all Emanage inputs and parameters to a CSV file which you can then import into Excel. Then all you have to do is use Excel to convert the voltage from the AFR sensor into an AFR via a lookup table. Then you can draw graphs or whatever you want. You will also have to convert the throttle position voltage and boost sensor voltage into their correct values, which is just a simple formula.

SimonR Posted August 8, 2005 Author Share Posted August 8, 2005 I can see the connection marked "boost". Which is the "second Airflow input"? Thanks. Quote Link to comment Share on other sites More sharing options...
SimonR Posted August 8, 2005 Author Share Posted August 8, 2005 Ta gents. Any suggestions for anything other (cheaper) than the AEM? Quote Link to comment Share on other sites More sharing options...
SimonB Posted August 8, 2005 Share Posted August 8, 2005 I can see the connection marked "boost". Which is the "second Airflow input"? Thanks. It's one of the wires in the main loom. White is the airflow input #1 that you will have wired into the input from the MAP sensor. Yellow is the 2nd airflow input. I don't think you'll find anything cheaper than an AEM - that's the cheapest I've seen. You can get a version that doesn't come with a gauge which is cheaper though, but if you have an E01 or don't fancy using a lookup table to get from voltage to AFR you'll want the one with the gauge as it has a linear output.

SimonR Posted September 19, 2005 Author Share Posted September 19, 2005 The AEM goes in tomorrow. Before I do something nasty to the electrics, can I just ask you guys to confirm that I will be intercepting the Yellow (Airflow input 2) wire in the picture and connecting the white (5v) wire from the AEM onto it?

SimonR Posted September 19, 2005 Author Share Posted September 19, 2005 Yup, got that. Hours of fun going over log files. What about those wires then? Quote Link to comment Share on other sites More sharing options...
Ian C Posted September 20, 2005 Share Posted September 20, 2005 Yes Yellow on E-Manage connects to White on AEM gauge. -Ian Quote Link to comment Share on other sites More sharing options...
SimonR Posted October 15, 2006 Author Share Posted October 15, 2006 Dang, I forgot to sort this out before the controller and sensor were installed. To save me a lot of time pulling the dash apart, can anyone advise whether the white 5v output that I want to connect to the Emanage comes from the sensor or the controller? Ta.

Ian C Posted October 16, 2006 Share Posted October 16, 2006 Use the wire coming from the gauge/controller and not the O2 sensor itself. -Ian Quote Link to comment Share on other sites More sharing options...
