I just got my EMU installed in my 02 G20. I wanted to get familiar with it before the SR20DET swap. I'm glad I did! I am new to this unit and piggybacks, but not tuning. I've tuned with SCT, F.A.S.T., and a small amount with Hondata. I have a few questions I hope someone could help me with or maybe point out something I have missed. I hope this doesn't overwhelm. Any and all help will be greatly appreciated. Thanks in advance.
1. When datalogging I have no engine speed reading. I re-checked all my wiring connections today and I had spliced into a cam reference wire instead of a cam position signal. I corrected the connection and thought for sure I would have a signal. None. I do have the crank signal correct. I did not hook up the brown wire pin 23 to the control unit because the foot note in the instructions states "if the crank and cam angle sensors are connected to the ecu, e-manage will recognize the rpm without connecting the rpm signal".
I used a Modis scan tool and scoped out both cam and crank signals going into the EMU, they are perfect in every way.
This has left me stumped as to why I do not see RPM why on the datalog screen. Any thoughts, suggestions. I thought maybe I had a jumper installed correctly. Rechecked them all and I think I got them right?
2. I am also unsure which box I need to check so that I can have an intake air temp sensor and a knock sensor. I have a spliced signal from the IAT going to c38 blue/yel of the EMU. I have the a spliced signal from the vehicles knock sensor going to C32 blue/yel wire of the EMU. When opening CH settings I check the box for intake air temp sensor, then from the drop menu under knock signal, choose in. temp/knock and the check is removed from the IAT box. If I choose w.temp/knock in the drop down menu the box is still highlighted for the IAT, but when I open the datalogger and choose my input data set-up only intake temp sensor is an option, the knock sensor 1 appears but is faded and the box can not be highlighted to turn it on. I have to be missing something simple here?
3. I am also experiencing some software issues. When opening a fuel, spark, or IAT table I can not scroll to the bottom of the table. For example on the injector adjustment table I can scroll all the way to the right and back left to see 500-8,000RPM, but I can not scroll to the bottom of the table to see 5V on the MAF side. The numbers stop at 4V and I can see half of 4.2V. I'm assuming the table continues on 4.4, 4.6, 4.8, 5.0? How do I get to these other cells?
I bought this unit used and was assured it worked perfectly. It had no CD and I downloaded the software from this site.
