AEM Standalone

[RobDET]

I just signed up for their board becasue of all the rumors flying about. This is straight from the horses mouth. An AEM engineer.

I can't wait!

I've read that a while back ago when it was posted. Also they now have a Nissan section on their boards, although it is too late because I have a haltech e6x next to me. The only thing my haltech doesn't have is 32bit Win32 software (unless E11), knock control, and plug-and-play. I wouldn't mind having an AEM though as I've seen how simple they are to work with. Guess I can just get a J&S safeguard and call it a day.

Kinda off topic, but do you have a decent haltech map I can take a look at? I've been trying to collect as many standalone maps for the SR20 as possible and have yet to see any half-decent haltech ones.

I'm still deciding on my standalone and have come down to one of the following:-Power FC D-Jetro-AEM (just taking a standard honda box and doing the wiring for the SR myself)-Microtech LT8s-Haltech e6k

Of these I've had direct experience with the haltech (on DSM's) and the AEM (on supras and 3000gt/stealths), but I'm still undecided...each one has its pros and cons.

Woo hoo!! :ylsuper

I can't wait until I find myself a nice and rich Newport / Corona del Mar female to buy me car toys.

No not yet. I do not have mine installed yet. I did however work on the ignition map a little bit so far on my computer based on tips from Scott (former Secret Services crew with 5XXwhp stock bottom SR). Fuel should be easy to mess with after it is installed. Just run it overly rich and take fuel away until it has the correct AFR throughout the map.

True. I'll be using scott's tips as well for creating a timing map regardless of what standalone I use.

I'm thinking of the microtech purely for cost issues. I can get the LT8s and the laptop software/cable shipped straight from the company in Australia for about $900US, which is the same as most US dealers (phase2, tougefactory, etc.) sell just the LT8s for

You can't use the Honda AEM ECU becasue the coil packs and the cam angle sensor are significantly different. This is something they discuss on AEM's board. They had to make modifications to the "daughter" board to get the nissans to run at all. All AEM computers are the same but there is a translator between the sensors and the main computer. They call it a daughter board on the AEM message board.

It's a hardware difference for the Nissans is what i'm getting at. So the honda box won't work at all.

I'm aware of that, but it works to some extent. There is a member on here (username is compression) that is running a Mitsubishi (evo 8) AEM on his SR20 powered datsun 510. I've got his full write-up on how he got it working.

Yah... sorry if i came off all harsh and stuff... that wasn't my intent.

Anyway about the EVO guy. He posts over on the AEM board as well. I think He and AEM worked closley together to get the hardware straight before he had his car running. From what it sounded like he had to have them fiddle with the EMS before he could begin setting up the maps.

I'll have to talk to him some more then. I've got the list of what sensors (both stock and aftermarket) he's using, as well as a quick rundown of how he set it up, I wasn't aware of any hardware tweaking he did with AEM though.

I could be wrong... It's happened before It may also be a different guy out in the AEM forums.

[msaskin]

I'll talk to compression and see what he has to say

I did work closely with AEM for the installation of their EVO 8 ems on my S13 SR20DET, very closely. In fact, I used to work there, so I had access to all the resources I needed for the install and setup. Although I did leave there before the car was ready to start.I did this before they had any plans on doing a nissan application for plug and play, otherwise I would have waited.THere was no hardware tweaking necessary, just made a custom wiring harness.To get the engine started for the first time was challenge for a few reasons:1. I had the cams installed wrong (duh!)2. I was very new to the software ( I did not work in that dept)3. A few other misc problems that were unrelated to the ems.

But after getting the I/O's configured correctly in the software, fixing the physical problems (unrelated to the EMS) and adjusting the crank fuel, and sync'ing the ignition timing, it started up pretty good. Currently it has very well functioning maps. I am going to get it fine tuned on a dyno soon and see where we can squeeze out some more power.I highly recommend using a MAP sensor, they are soooo much easier to work with and there is really no good reason not to use one instead of a MAF.Any EMS will work as long as it has four coil outputs (which I think they all do) and you buy my cam sensor disc that installs in the SR20 cam sensor and gives a signal any EMS can read. And of course, you wire it up correctly with all the proper sensors.

[RobDET]

Yah it was the cam angle sensor that required the major change to the EMS right? I wish they would announce a release date for us Nissan guys

Scotts tips for making ignition tables? Where can I find this info.

Here's the link to the FA thread where scott basically details creating a timing map
