I compare AEM and Haltech E11V2. AEM has more features: two O2 sensors support, knock, standart harness and sensors support for FD. Both have OMP support. But AEM has some troubles with FC crank sensor and more bugs.
Please help me to do right choice.
Eunos Cosmo 13B-RE Single Turbo.
Thank you!

 

That choice will boil down to basically what system you can get the most out of, so a couple of questions you have to ask your self:

1. What's my budget?
2. What's the car going to be raced on?
3. Will i use a stock harness or a new harness? (i recommend the haltech in this particular point)
4. Will i benefit from one system's features, or the other's?
5. Will i have support (both system's manufacturers provide support, but its good practice to pick a system that you can take to a well known/knowledgable person.

If you answer those, you will probably decide easier between either, but in general all EMS will work the same.

 

Thank you!
Budget on EMS is $2000-2600. Prices of Haltech and AEM are simular. I will make new harness cose stock harness in cosmo is different FD harness. But ECU connectors is the same.
Haltech has more open sources than AEM. Haltech support 3-rotors. AEM has more bugs in software and more difficult to run well. Haltech has less possibilities in fine tuning and use sensors.
Car build for drag race show in Russia, but not pure dragster. It is for show to a greater or lesser extent.
Haltech has more support in Russia today, but AEM is more perspective for dealership in Russia.

 

???
Do you know something the rest of us don't?
Or are you just talking about the fact that Haltech AUS releases firmware and program upgrades freely from their website?


I thought you only mentioned 13B-RE?
If you just want to control a 2 rotor, look at the E8; the E11 is overkill for a two-rotor.

So does AEM ...

As for features, the AEM does outdo the Haltech, the E8 can run both a 2 and 3 rotor engine (3 rotor in wasted spark), but the E11 would be best for the 3 rotor. The AEM hasnt been proven on the 3 rotor. Price wise, the E8 is a little lower than the AEM, and the E11 is basically the same.

If this is a Drag/Show car, and you will only run it a few times out of the year, i would just get the E8 (for 2 rotors) or the E11 for 3.

And take advantage of the haltech flying lead harness which will be better since you dont have one now.

 

I want to buy 20b next year and tune it as well.
I choose haltech e11.

 

E8 does not support OMP.

 

I told about a haltech have more sources "how to do it".

 

Yes it does, or do you know something we dont? the E8 is an E11 with less outputs and inputs.

 

also the e11 maps at 32x32 correct? vs e8 is 16x16..
E11= a change every 250 rpm allows a diffrent rate of fuel from 1kto 8k
E8= a change every 500 rpm allows a diffrent rate of fuel from 1kto 8k
correct, or did i miss something in my research... also the e11 has more inputs for sensors?
that is the reason i am going to be choosing the e11, unles i am otherwise purswaded...

 

As Claudio RX-7 has already mentioned, it does.

WTF would you want to run OMP on a serious engine???

Ah, a language translation problem...

Yes, Haltech is a lot more popular with the Mazda 13B rotary engines.
This is why you will find more information on them.

I dunno where you're getting your information on the E8, but it's wrong.

The E8 is basically an E11 with less outputs and inputs, yes.

ok my bad, i see i was origonaly comparing the E6X to the E11, i read that the E* also maps at 32x32, but it that true about what mapping structure means?
E11/E8= a change every 250 rpm allows a diffrent rate of fuel from 1kto 8k
E6X= a change every 500 rpm allows a diffrent rate of fuel from 1kto 8k
correct?
this would lead me to beleave that the e11 and e8 Both have 4 times the mapping 'depth' as the E6K..

 

Dude, the E11/E8 program allows you to configure what ever load points you want and what ever RPM points, maximum RPM for it is 16000 RPMs. The resolution is 32x32, but you can put what ever you want in between.

RETed, you would want to use an OMP in a serious engine to have proper control of the oil injection and make sure your engine is on the safe side. Personally i feel that putting in oil in the mixture, although good in many ways, it puts more crud on the fuel than what id want. But that is my own personall opinion, im sure everyone here might bash me for it.

 

I bought E11 deal package and some solenoids and sensors for it yesterday, and wait it for shipping over Russia.
Thank you, guys!
