well, i like the usb on the series 2 and it runs a little faster if i'm not mistaken and also an extra quick on the fly tune switch capability.

we'll see though...i won't need to buy one until late this year when i get back from iraq and finish my rebuild.

So far I realllly ******* like this EMS. Just got one a few days ago. I've been able to tune out some drivability problems that I've been having with my PFC and bridgeport.

I'm looking forward to boost correction tuning. I'm going to do a hybrid style where only the boost is corrected. Once I get my vacuum map all dialed in do I just make everything from 0psi on up the same inj pulse throughout the rest of the load, correct?

Sorta, you can start out that route but my maps never were 100% 2D in the boost areas.
Here is a view of a med port map on a T72r. You can see the boost area is not 100% 2D but it's what the car wanted.

gotcha, thanks.

I guess I was just trying to say "don't get tied to the idea that the fuel map needs to look a certain way. Start out with a 2D look but dont be afraid to adjust the positive pressure rows differently. "

Anyhow, I really like the wild setups avail with the AEM :-)

This is not a preferred method of tuning. You are wasting resolution. If you want to use the boost fuel correction table your fueling map should be TPS as load. you can have it set as map as load and have boost correction but it is not a very efficient way of tuning. If you can see in hwnd's photo it shows TPS as load.

What are the the 2D boost areas?

GSR, I have a few throttle based maps that I may be able to help you with. They are for stock turbos but the car didn't have a stock injector setup. I can make some adjustments so it might work for you.

well instead of doing tps I'll just do it the old way that I'm used to.

I just found out my flipping lc-1 isn't working now. I don't know what went wrong but since I've connected the EMS my analog out wire is putting out 0 volts. My innovate A/F gauge works just fine. What the hell happened?

hwnd

iTrader: (4)

Uhm, try taking a multi-meter and measuring the voltage from the wide-output, assuming its outputting a voltage, and adjust the o2 gain in AEM to display the voltage from the multi-meter.

thats about how I do mine anyhow. if your amplifier isn't outputting a voltage then ... :-)

Aeka GSR

iTrader: (4)

Yeah I've already checked the LC-1 output with a multimeter beforehand, completely dead. However I've been told that I can reassign outputs on the LC-1, too bad I can't get the stupid thing to connect to my laptop.

henery cant support my build at aem
because its not a fd ?
i have a 89 jdm 13b with 3rd gen jdm coils
i have fuel map / breaker point issues car and tuner dont do well
it is like the key is off 4k - 5k rpm otherwise i can work it out
dyno is ok but at track i sucked
http://www.youtube.com/user/chrimpat.../0/PZWAGfm49cg
this is the last pull then track would not run 4-5k
air fuel was going crazy at that point

anyone have the rest of that pdf on the first page?

the rest? We have to provide input to make the rest.

We're busy with non-car stuff... we'll get to it with photos and junk at some point.

i'd honestly look at the AEM2 software package as the help-system inside is pretty good!

Or you can just ask questions... there are some of us who are always glad to help.

well im waiting on the series 2 unit but if it doesn't come out in time i might have to use the series 1 instead. There was just a lot of good info in that pdf that I'm reading up on. didn't know you guys wrote it, did a great job.

thanks,

anyone hear any info about the series 2 PNP release?

iTrader: (17)

I called AEM last spring, around April, and they said it was coming out this summer (2010). Summer has obviously passed so either it got delayed or they just aren't doing it.

While they didn't sell a lot of Series1 boxes for the FD, it's not like it would take much for them to release a series2..they have the PnP clips and hardware for it.

Really, the biggest reason I speculate as to why we will never get a Series2 box is because AEM and their vendors are probably still sitting on quite a few Series1 EMS' and releasing a Series2 will make them have to drastically cut prices on the Series1 or just junk them...again just a hypothesis. And they probably speculate (correctly) they would sell very few.

I was thinking the same thing. Its not looking good right now. If anyone heard or hears anything keep us posted.

All of the options for the RX7 are in the series 2 software. that means a series 2 EMS can run an FD. The only thing that is not available is the PnP EMS. If you really want to you can buy another Series 2 EMS and make a jumper harness for the Stock FD wiring. If anyone decides to do this you will have to pick the series 2 EMS ECU you start with correctly.

Yeah, and thats what I'm still trying to hold out for, the PnP. I want that vehicle specific PnP tech support, instead of trying to figure out everything for myself. I could have a shop do it but than I'm looking at a higher price tag. But I will say I'm growing more and more impatient for this series 2 ems.

This is not 100% correct, although for the most part you can make another EMS run a 13B, it would largely depend on the faughterboard and on the S2 ECU's, some internal settings.

Honestly the S2 ECU will not mean much for the RX7as it has for other applications, as there are no real issues with it running it currently that could really be improved on, other than the boost control for the seq twins, and the ability to use a USB port instead of an adaptor.

Not sure I would bother waiting. Currently Summit has the FD 30-1800 box for $1299, and I can match it or maybe even do a little better on it. Thats an outstanding price for a very powerful ECU. I have basemaps proven to work for many setups including stock, single turbo, etc. as well.
Oh, and I have one in stock and they are also in stock at my vendor as well
Cheers,

You would get support from the person/shop who built your adapter harness. then for the EMS support you will have AEM support the specific EMS you have. You might have a better chance of waiting for the Series 2 universal to come out. then you can get support for whatever engine/car you put it in.

That's why you will have to deal with someone at AEM to help select the Series 2 ecu you start with.

You can repin the inj 9 or 10 output and define it as a third PWM output and be able to have finer control over the precontrol solenoid. Plus you can use the EMS2 editor with the series one ecus. there s no support for this. I have seen it work so I know id does but I also know there are a few issues that make it far from perfect.

Couple of things-

Aem does not generally give too much support to the end users of the universal ECU's, as this is why they only allow specific shops/tuners/installers to buy and install them. Or at leastit used to be that way, and yes, I am one of those.

Yes you would need to work with someone at AEM to help select a unit, although honestly youor your tuner could do this if you know enough about how ECU's work and the signals they need to work.

Personally, I do not like the AEMTuner software and prefer Pro. Because Tuner is designed around the novice user, it is clunky and heavy and slow. I understand that AEM may or may not release a "light" or pro version of tuner for those who do not need all the extra "crap" running in the background.

Also, yes you can repin the ECU and gain an additional measure of control for the seq turbos, it just is not as perfect as it could be. Something I am working on is using the VVC tables to provide finer control over the PWN output and therefore getting closer to the factory operation.

I tuned a 93 eagle talon on aem ems series 2 and hated it. It is a waste of time to learn a new software if you know the old one. and there isnt any hp gains from it, I probably could have gotten more power out of it on the old system, and it took me a lot longer to do it.

I have been tunning cars here in Idaho on aem ems series 1 since 06 and I am really fond of it, imo its the best system available for anything. Just put it on my fd and it seems very responsive, much better than that waste of time apexi and the datalogit junk.

Dont think that just cause its newer its better. Dont waste time, if you dont have aem ems get it.
