As with any of the aftermarket engine management systems, the warranty is at the manufacturers discretion, if you hook the wires up wrong, and burn something up, it can be repaired, but no warranty, the warranty against manufacturers defects is 1 year.

The units are made in the USA and serviced here as well.

If you have the demo software, it is the same for any range of map sensing. the vertical axis is just labled differently.

Jason.

 

That's what I'm interested in seeing!

You will not be able to see the labeling until you have the final software (available with the unit).

hi jason the system sounds good, looks confusing to me a novice could get in trouble real quick, if its so good how come the AEM sonsored car has two Gold boxes.

So basically what you're saying is that I have to buy the unit and hope it's what I'm looking for!

The "Y" axis is scalable by the user, the ONLY difference between what you have and the actual software is the numbers on the "Y" axis are scaled according to which map sensor you are using, the demo software does not. So if you have to see that it says o to 500 kpa, then yes, buy one.

Jason.

 

The key for me is will it really be available by end of January or early February. I heard the Supra version was to be available in January and it will not make this deadline. I can't have major delays.

I apologize if you have already answered. If you have, just say so and I will re-read from the beginning...

1. The AEM can manage a 3 rotor. Do you guys have any 20B related fuel/ignition/etc. maps?

2. If I purchase for my current set up (13B), then upgrade to a 20B am I going to be able to purchase the racing harness separately?

3. If a significant mod to a set up is made (upgrade to single turbo, or MP instead of cat), will suitable maps be provided by AEM? Can this process be done via email? Will AEM have a website to host different maps for different set ups?

Anyone else that knows, please feel free to answer.

TIA

 

20b Base maps are the same as 13b, it just has an additional same size chamber.

No, you can use the same harness, and use the proper pins that already exist in the 13b harness.

No, we off base maps, intended for you to get the car up and running faster, but by no means are they intended to go out and race on. Every engine requires different fueling, even engines that are nearly identical.

As far as hosting different maps, we will not do this, mainly because it would imply that we trust what has been given to us as a good map.

Jason.

 

For the guys that didnt feel like reading the last handfull of pages (I know its long). I thought I'd throw this post in as a condensed version of what I've learned through asking Jason a bunch of questions on the prior pages regaurding tuning issues I had. Maybe it will help someone.

The AEM comes with a very basic map to get the car running.

You will have to use a wide band while tuning the AEM either on the street or dyno just like every other computer in the world.

You have to do the first initial tune manually. After that for mods updates and such the AEM can tune itself when you promp it to by building a new map. The AEM has to be hooked up to a laptop and you need to be running a wideband(like stated before) for this feature.

The AEM will data log for 45min, if you hook it up to a laptop it will data log as long as you have remaining harddrive in your laptop. If you want to data log using the AEM's harddrive for 45 minutes and you dont have a laptop you can buy a long computer cable and hook it up to a regular computer at the house to download the file.

The computer has a TON of features and can do everything under the sun.

If you want this computer to eliminate your tuning troubles you'll need to buy a wideband. My understanding is they start at around $650 and only last for about 50 hours (which is a pretty long time if you only use it while tuning)

I hope this will help someone, if any of it is wrong I'm sure Jason will correct me.

Later,
STEPHEN

 

SPOautos,

The 50 hours is with leaded gas. I think that the average wideband lifespan will be significantly longer (don't know if it will be enough to leave it installed - depends on what kind of gas you are running). Still trying to figure out how I am going to apply a wide band. The tail pipe version is great, but I don't have a MP, I am running a cat and therefore injecting air into the system before it makes it to the tailpipe, that will screw the O2 readings. I have been thinking about going right before my cat and installing another boss for a second O2 sensor. Small PITA. I might just jump to a MP and orifice it to keep my boost creep under control, then use a tail pipe sensor. Are you buying a wideband? What's your plan?

So, I guess that I have been misinformed. I had the understanding that they were going to provide a safe map for the mods that you had. Sounds like they are providing a base map for no mods (or a few basic mods, similar to the PFC). From that, you will have to increase fuel and adjust timing (etc.) accordingly. Makes more sense that way. I was having a hard time understanding how they could have a map for every combination.

Black680hp7,

Thanks for answering my dumbass questions, I have one more. I get what you are saying about using the 13b harness, but lets say that I might not want to use it. Please confirm that the racing harness is not available separately.

 

mmaragos, your probably right. After reading your post I did a search in regaurds to wideband lifespan on the "Lightining in a world of thunder" web site and found this......

the sensor lasts about 500+ hours on pump gas and about 50 for straight leaded/C16


I imagine it probably varies from brand to brand but anyway this is prob a good general life span. I have a friend that wants to get one and we might split it. The only prob is his Wold that he has doesnt accept wide band and neither does my Power FC so we'll have to get one that datalogs and they cost over $1K. Of course between the 2 of us we'll almost spend that in one session at the dyno to tune both our cars. If I get a AEM I wont need the datalogging portion which means I can get a cheaper unit like the $650 wideband. The only prob is Brian cant use it so I'd be buying it by myself which would be more $$$$!!!!!

I'm like you I dont really know what I'm going to do. I do know however, that if i get one I'll install it in the dp and just screw in a bolt when I'm not running the wideband.

Later,
STEPHEN

 

The racing harness is available seperately, but it will not plug in to the plug n play ecu for the 7. So you will need the universal ecu.

Jason.

 

It has been to my experience that wideband o2's and UEGO sensors last much longer than they claim. I have had one for about 8 years, and have probably half of its use with leaded race gas. I have found that once it starts to respond slowly, I just put it on a car close to the exhuast ports, and run unleaded gas, and burn it clean again. I have compared this thoroughly abused sensor to a brand new one, and they track perfectly. Just food for thought.

Jason.

 

Black680hp7, if I get the plug and play unit will I be able to conrol my Aquamist Water Injection or do I need the race version?????

Also as most of us have heard shipping seems to have been delayed till mid-February for the RX-7 plug and play unit. Is this correct???

Thanx for your help.

Ken

 

Black680hpRX7, I plan on buying one of these units as soon as they are avalible, my question s this; I run a 6 injector set-up on my FD (6X850) and i don't want to change the injector arrangement. will I be able to use the plug and play system or will i need to use the race system.

I'm interested to see that the plug and play ecu and the race ecu are diffrent units, what other diffrences do they have besides harness incompatability?

will the race system have controol over all the same functions that the plug and play does? (OMP)?

which system do you run in your car?

and this might have been brought up before, but i didn't see it; will the plug and play system be compatable with an aftermarket air temp sensor?

 

I just read all of these posts, and all I can say is thanks Jason.

Some people seem to look a gift horse in the mouth.

How many of us had even half of this information when we "blindly" went out and bought our PFCs? Not to mention the great support we get now.

If this turns out to be what Jason says, then APEX'i can take their PFC and shove it, along with their proprietary XCEL software. Bastards
And here I am thinking about spending an additional $300 to get the functionality of this ECU. Choices, oh choices.

 

A good spray from some propane gas seems to work good too!
What the sensor can't tolerate is a high % of moisture. Thermal shock would destroy a brand new sensor in a heartbeat! I would normally let the car I'm tuning get up to operating temperature before installing the sensor.
Also I've found the NGK sensors to last the longest.

The plug n play will still work with your 6 injectors, you will just need to do some minor wiring.

No differences between the plug n play and race, just plugs

I run the race system, because I purchased my car with an engine fire, so I had to replace all of the harness.

It is completely compatable with aftermarket sensors.

Jason.

 

my car has no harness in it currently (i was planning on going haltech) but the plug and play AEM just seems easier to deal with.

and one question i'm supprised hasn't come up.. Jason, can we see some pics of your car, specifically underhood pics. i want to see how clean my car will look with a race system installed and the stock wiring out of the way.

 

Here are some pics of my seven

Jason,
looking at the picture of your car makes me want to ask more questions.
Is that 1/4 mile gear I see?
What kind of 1/4 mile times are you running?
