I use a 3d table for ignition retard on the anti lag, using RPM vs. MAP. I retard timing until the boost level I want to leave at and then taper the retard away and hover around 5deg BTDC or so. It does a really good job of holding boost steady on the line.

Just wondering if you have that capability. Most systems don't have the option to retard relative to MAP and you end up with something that builds more and more boost the longer you're on the anti lag.

 

LOL!

Hmmm, interesting thread. I got the link emailed to me today and just read the last 11 pages. It's interesting because I not only work for AEM but I am working on the GEN2 EMS as well. There is a ton of misinformation in this thread and I was going to quote a bunch of posts and reply to each but thought better of it. I'll just post it here and you guys can do with it what you want.

1. The V2 EMS firmware is 100% new from the ground up. Nothing has been carried over from the standard EMS. Not a single line.

2. The Hardware for the Gen2 EMS is totally new as well. The Evo8 and Evo9 plug & play units have peak and hold drivers now as well (contrary to what an earlier post in this thread said). They will also have upgraded knock control, a larger internal logging memory, USB comms (6-10x faster), much faster processing capability and a bunch of other things.

3. None of the Mitsubishi V2 units have been released yet. There are many betas in the field undergoing final testing but no production units have been made yet.

4. The cam sensor is an electronic device and is a critical input to the ECU. Mounting a 1,500 degree huge chunk of metal literally inches from it is playing with fire (no pun intended ).

5. When the EMS loses the cam input it loses "sync" when that happens the fuel and ignition events are stopped and the AEM requires a complete cycle (720 degrees) of proper cam/crank signals before it will fire the injector and coils again. Same at startup.

6. AEM is committed to making the best direct plug in ECU we can and bringing it to market at the most competitive price possible. We started making boxes for DSM's in 2002 and the V2 EMS rolls up everything we have learned during the last 7 years into a totally new unit with a new code base and totally new hardware.

EDIT: I just noticed that in 3 years on this board I have only made 4 posts. That's pretty lame.

 

Nice to see you over here.
Time to increase that post count then!

I've asked this before but since you're here now. In regards to the AEM hard starting on the EVO platform, well actually the long time to start sync. Is AEM going to resolve this issue on the GEN2?

 

Seriously. Everyone seems to have it figured out but you guys lol.

 

Motec and their 3d tables. The flexabilty it gives to the end user is unmatched by many other systems. Sometimes you can get the same results with a lot less.
I've tuned and set up cars running only on a 'fuel' only ecu using a distributor and a single MSD ignition. When innovation is required for more control simply wiring in a couple of resistors and diodes on the clutch switch delays how quickly the advance/rpm returns. It's the poor man answer to expensive control. Can't argue with the consistent launch boost/rpm it produces resulting in very consistent 60ft's and timeslips.
I've seen many systems do what you describe with their 'antilag' setup where the launch boost is not controllable. Not going to mention any names.
Most systems are designed around just a simple retard program. Most have a combination of different programs that give the end user better control. Some have all the above but yet the results still sucks.
So far from my experience with Haltech ecu's with launch control the rpm never over shoots when antilag is being used. The boost is simply set with the amount of retard used and with the way the soft touch limiter is setup. Then there are other methods 3d/dual ign & fuel map, rotational idle etc. activated with launch/antilag control that can be combined to get the same results.

 

Actually there's nothing to figure out. And as for those 'you guys' you mentioned, if you got nothing positive to add then don't reply to me please.

 

seriously.. Whos everyone??? The AEM starts like Crap compared to Haltech..

 

The HKS FCON PRO uses a 3d scramble table, retarding vs boost level is one of the functions it can be used for................

Motec is a great system, maybe the best. I like the newer systems, people don't want to pay.....

Motec's software is the greatest on many aspects. It's up to the end user to decide if they want to pay for those advantages the motec offers.
Pro EFI also got many aspects to it that rival many other top of the line systems out there. Then again only time will show those advantages when the unit is more established.
In the end you get what you pay for. Well at least sometimes!

 

It appears after 3 years on the Board only now is AEM showing interest in fixing certain nagging issues.. They have 95% of the Standalone market probably for evos in the US but i have a sneaky suspicion that is going to change over the next couple years.. I personally found my cars to run MUCH better on Haltech vs. AEM from a driving perspective...

I can imagine a lot of things happening and all of them end with you uttering very colorful metaphors!!

 

It seems that perhaps AEM will no longer use a GEMS based main unit with a patch and they are making their own unit from the ground up - a great development - this is great news

I love AEM and I love the fact that after so many years of working with it on a near daily basis and also being trained in CA that its very easy for me to tune now - hopefully the new boxes will fix some of the minor bugs

FYI - the AEM in my Subaru STI is flawless - really great unit

From what I have seen, Pro EFI will be THE new ems.
