It seams that the information available to us on how to setup AEM EMS is somewhat limited. What I want to get documented here, is how to setup the basic.

1. Rev limiter to replicate the stock ECU (6k cold, 9k Hot)
2. vtec change over to replicate the stock ECU
3. AC Setup
4. Evap setup
5. Closed loop tuning w/Wideband
6. Any other basic things that need to be setup, prior to tuning.

I know there is a number of EMS installation out there, and I am sure the setup is basicly the same for a number of setting, but there is no central thread with them. I wanted this thread to serve that role. AEM forum seams to be short on info in these areas as well, and fairly inactive by AEM support personal. Atleast in our sub forum

Thanks

 

I was actually going to start this on my site in a few weeks so this should give me a good place to start.

 

This will be a great thread, especially if we can figure out how to control the EVAP!!

 

Can not be done from what I've seen. The only way to set up the 2step rev limiter is off of a switch or vehicle speed. If there was a way to set the 2step input to user#1 then you could do it, but it's not an opinion in the software.

I'd need to know what you mean by "replicate" the stock ECU. Here are the options you can change in the VTEC operation.


Again, what are you wanting it to do?

Evap controls are...
LS3, Bypass solenoid valve
LS4, Purge control solenoid
LS5, Control canister vent

The problem is that the factory ECU uses a votage levels from the sloenoids to turn on or off the evap system. The EMS does not read voltage off these lines. It's either 5V or ground.

It's right in the EMS manual, once you set the Pro and INT gains it's a simple matter of filling in the table with the appropriate AFR levels you want.

The calibrations for the ECT and the AIT should be set. They are not accruate from AEM. Here are snap shots of numbers that are more accurate.



That's all for now, can't give away everything or I'll be out of a job

 

you could set up the two step on a switched input, you could use a thermoswitch if you could find one at the range your looking for. but if you going to be tuning your own ems, I think your smart enough to take it easy on your car until it gets up to temp.

 

Scorpion got all of the basics covered right there. At least for the most part

That AEM forum is kinda slow. With everyone that posts and the AEM tech's.
