E-Manage Tuning Information Guide

[Maeda]

Ok suckers. To help enrich and enlighten the 240sx community on zilvia i'm posting this guide to e-manage tuning so nobody repeats my 450$ dyno session. Other's PLEASE ammend or add to this guide as my experience is not everyones and I'd appreciate another point of view.

E-manage is a piggy back engine management system so it needs to run on the stock ecu. It controls mafs, larger injectors, addtional injectors, injector duty cycle, and ignition timing.

To get all the nice features you need the laptop harness and software, or the profec e-01 boost controller, or the e-01 programmer.
These tools will unlock the 16x16 maps. E-manage can also moniter greddy warning gauges, as well as RECORD up to 3 hours of data (including tps, maf voltage, rpm, boost, and yes you can rig a wideband to it too!).

Stock is a 16x16 map so i'm told
S-AFC2 is a 12x12(?)

How to tune the maps is laid out by the e-manage and e-o1 instructions on mohdparts.com.

The large PROBLEM with the emanage is that is has trouble tuning on certain systems INCLUDING the 240sx. ECU's use the O2 sensor to sense the air fuel ratio and adds or subtracts fuel accordingly, until WOT when the ecu ignores the O2 signal and just runs a preprogrammed map.

The e-manage CANNOT tune the portion of the map that is being adjusted by the ECU + O2 sensor. They fight and the ECU always wins. I waste about 2 hours on a dyno attempting to tune this section.
