If i connect this EMS to a laptop, does the software have a monitoring setting to where i can drive the car and it will show me some engine stats? Kinda like the VAFC has?

Also can different tuning settings be saved and loaded when needed? For example, have a setting of the car tunned at 12 psi for street and another for 25psi for drag. Can this be even done? Is there anything outthere like this?

The reason i ask is because ive never seen nor know much about the AEM EMS other than its a great ecu. I will like to use this for my setup but will like to get some idea of what it can do other than tunning.

#1 yes, they call it data-loging, and #2 yes, but it will just recognise the pressure increse from the map sensor and then automaticly revert to the fuel table you alwredy programed when tuning. no need to reload. hondata, and uberdata will do all this too. you should check out there sites.

 

So if the computer is program to recognize 10 to 25 psi of boost, as long as i dont exceed 25 psi, it will just adjust the fuel/timming ect, to what it was programmed at that specific boost and RPM, correct?

 

Also is there anywhere online where i can get a lesson on tunning any of these EMSs? I know the basics but would love to learn the debts of these systems? How did those who know here learn?

yes thats correct

 

Wow AEM has a demo software version of their EMS, downloading it rightnow...this might be of some help. Anyone else seen this?

 

Its not a demo actually its the full version. The software is free, the hardware is expensive.

When online the AEMpro software will show engine parameters in real time via the serial connetion to the EMS unit.

 

while we are on the subject of aem ems questions..

if you have the ems and you get large injectors, do you still need to wire in a resistor box (like with hondata), or can it work with any kind of injector?

thanks

 

Yes you still need a resistor box, or you will kill the injector drivers...

 

not true the AEM can run on any type of injectors.. you just have to set it up

 

If you run saturated injectors you don't need a resistor box but if you run peak and hold you with need the box... The biggest I have seen is 550cc for saturated injectors!

 

aempower.com has god info talk to the supra guy they do crazy stuff with ems. als you also do have digital dash on ems which you can change around to have like rpm's coolant temp a/f ration knock. with ems the is no need for gauges. you can also set your check engine light as a shift/warning light

Do you even own an AEM EMS?

At what point did I say you can't run P/H injectors? You can run any injector with the EMS, but the question was will he still have to use the resistor pack, and the answer is Yes Much like the way I have My P/H injectors wired up to my EMS.

Please read more carefully before replying next time...

 

To clarify the original question a bit....

While the car is on you can see everything change in real time with the software on your laptop. You can datalog any of the parameters at 250 times per second and this allows you to see relationships between the parameters. For instance I regularly datalog these parameters together.

Engine Speed (RPM)
Map Sensor (PSI)
O2 sensor (wideband)
Throttle position
Fuel cell value
Acceleration fuel addition
Total fuel injected

With these and some others I can make a run and view all of these together to make determinations of where to make changes to my fuel map or acceleration tables. This is a very powerful system and it all comes at no additional cost, unlike many other systems.

There are even some math calculations that can be done with the datalogs to calculate things like torque and horsepower. In addition, the current version of the AEM software (version 1.03) has no problematic bugs with Honda's and in the 6 months that I have been using it, I have no complaints at all. It is an awesome system that I can tune myself and at this point my car runs like stock and kicks *** !!!

the ems can run a boost/fuel table from vac to xx psi but it wont change your ignition tables so you would want to run a more conservative ign table on the street and load a more aggresive table for the track since youll be running c16 or equivalint fuel that you can run more timing .,

And your speaking this from experience?

If you run high impendance injectors you will need a resistor box. I think I should know, I have one.

yep still need a resistor box for p/h inj
