I'm currently in the market for a standalone, my mods are as follows, ams gt35rl turbo kit, ams 680cc injectors, ams fuel rail, hks 272 intake and exhaust cams, walbro 255lph fuel pump, arp head studs, and arp rod bolts. That is about all as far as the motor goes. I have all of the supporting mods for the rest of the drivetrain.

I'm currently running the utec, and i've run into a few limitations that have made me look into standalones, my tuning experience is substantial with the utec, but I have very little tuning knowledge with other units.

I'm debating between the autronic and the AEM ems, I don't like that the autronic doesn't have a knock sensor, and that it is not interfaceable with other wide band units.

I'm wondering if any of you have had experience with both units, and if so what is your preferance, and why,
please only respond if you have used both units,
thanks,
Rob

I have played with a few autronics and do not like them I have found that it is hard to beat the AEM EMS easy of use and the amount of function it has. The EMS is the only stand-alone I would use on the evo.

Or to look at it a different way, how many guys that are running low 11's,10's, or even 9's are using the autronic. I personally can not think of any, but sure can think of many that are running the EMS.

 

I don't have any experience with the evo ems, and very little with the aem. What I have seen are a lot of frustrated tuners (honda guys) at the track trying to make changes that work with the aem. I'm in need of something fairly user freindly, and was told the autronic was more easily tuned because it doesn't have as many functions to worry about. I however feel that it is limited in comparison to the aem, and i'm not excited about no knock retard functions...............

I suppose I need to spend some more time researching and studying the interfaces of each unit.

 

You have a GT35R?? Then not having knock control would be the deal breaker for me I love my AEM. I've messed with a power FC on my 240sx for a while, and it was very limited, at least with the little crappy commander keypad. The EMS is vastly superior IMHO. Lots of great features, you just have to have a pretty good idea what you're doing to get your car to run well.

 

I'm not quite sold on the whole audible knock idea, I want to be able to drive my car anywhere, and if for some reason the air gets a little less dense, and afrs start to change, I don't need to worry. I have a lot of experience with 2strokes, so i'm not unfamiliar with listening for detonation, however when you ride a two stroke, that is all you hear, I do want to listen to my radio once in a while in my car What worries me are the complaints I've heard about the extent of work needed to chang fuel/timing maps with the aem. I'm not a person who just went out and bought a whole bunch of stuff for my car. I know how an engine works I know how timing and fuel affect an engine, I know how timing advance changes load etc. I just don't want to end up with something that i'm not happy with, that is the situation i'm in right now and I don't want to be there again..............

 

motec !!!! only MOTEC !!!

 

I have the Motec PLM, does that count?

 

please be open minded . Any aftermarket EMS is only as good as a tuner can tune it. Here is an example of a fast Autronic equipped EVO:

Autronic is very easy to tune, but the fact that it doesn't use teh factory knock sensor really is a drawback for those daily drivers with pump gas. I guess you just have to tune it more conservatively for everyday use and leave more safty margin in gas you have a tank of bad gas.

Autronic has altitue compensation and close loop boost control... if that is what you are worry about.

I don't have experience with AEM, but seems like AEM is a very powerful unit which let you control just about everything. And the fact that AEM is less expensive than Autronic, you should seriously consider. Don't forget that AEM is based in USA, which you "should" be able to get better support. Anyone can comment about AEM's support when it comes to tuning (not warranty service)?

 

I ran 11.3 @ 127 at the shootout on an Autronic. 25 psi.

 

Micah, I'm guessing you work with Eric and Martin, they both run the aem am I not correct? So what advantages/dissadvantages do you see between the two???

 

No Autronic experiance here, but I can address the issue you raised above....

Swapping from one map to another complete map requires a laptop and some time to shut off the car, and load the new map. What I am doing is setting up the Nitrous control function as adjustment maps to the timing curve and fuel curve instead of using an entirely different map, just using the map adjustment functions without actually injecting any N20 is a snap. After all, the only things I change when I put in race gas are boost level, fuel trims, and ignition advance! This way, with the flip of one swith I am set up for my race gas

If they were having trouble with adjusting the maps while trying to tune the car at the track (not just switching between maps) then I have no idea what there problem was, the maps are VERY easy to tweak as needed.

Later,

Keith

 

Thanks Keith, that is what I needed to hear, the more I research the more I lean toward the AEM.

 

Rob make sure to get the Engine Managment that works best with the Prodrive battery tie down and vortex Generator. Let me know if you want the AMS cause we can get it for you.

Ben

 

Sweet, thanks Ben, I think the AEM probably has voltage inputs for both the prodrive battery tie down, and the vortex generator....lol...... it does for everything else. I'll keep you posted

 

You can load maps while the car is running on autronic. I don't believe you can do that with AEM.

The downfall to Autronic is the fact it has no knock contol. Either one can make good power obviously, but if you want more control over the car I would go with AEM. This is why I'm switching. I'm eventually putting spray on there and I want the knock control on the car just for the safety factor.
