Does GM MAP allow for MAF deletion?

[dsm-onster]

Okay, let's set money aside, ease of use and being able to set it up and tune ***MYSELF*** is my biggest concern as well as not blowing up my brand new motor or taking a year to figure the thing out.

I am not about to question your intelligence/skill. Afterall you did purchase a DSM. Good choice . It has been reported over and over again that AEM EMS is difficult for the novice to get up and running in short order. DSMLink: literally plug in and your car runs like it was from the factory... PLUS exceedingly superior customer service. You can talk to the designers online any day of the week. Great forum support.

I mean why would I need warm up fuel trims?

Mitsu did alot of research on warm up times for their 4g63... I trust their engineering. Why reinvent the wheel.

And would having control of the iac motor be for something such as getting rid of a stock throttle body which would maybe eliminate the iac?

Sure, if you're going to fork the dough over, you sure as he!! better get intricate control.

What's a COP setup? Not sure why I'd even wanna be controlling my timing at other than WOT Figured that's where the knock would start coming on anyway.

As I said before. The engineers at Mitsu did their research for closed loop operation for us. Why do that work when its already done and programmed in the stock ecu.

The more modified your car is, the harder the stock ecu has a time making it work like stock. AEM I spose is just a question of how crazy are you going to get with your car. It is your car, your investment... maximize your potential w/ AEM or have it run very well with dsm link and save some money.

Okay how easy are the instructions to get you started? I downloaded the demo but it really didn't seem to do much or to tell me anything. And since the forums are down, I really don't need to have any sorta problems with the thing if I decide to get this being that I don't know of anyone around here that could help. As I'm starting to wanna lean more towards it.

Well I guess the new versions of DSMLink that I have not seen have more stuff on them now. Thats pretty awesome. Sorry for my earlier post.

Most likely the best thing to do is talk to Dan S. from Garage_Defeat or John with Torque/Horse Power Freaks. Im sure if you talked to them they could answer all your questions and have reasons why to go with the AEM over DSMLink.

I mean if Dan can make EVO's run [email protected] in the 1/4 mile stock turbo, and a 11.9 with full interior, A/C, Stock bottom end and stock transmission and again on a stock turbo then he must have some reasons why the AEM EMS is good.

Also John got extra 40 or so horse power out of a stock viper, so again I would think he would know why this is a good system.

In the Supra video done by Horse Power Freaks they stress the "daily drivability" that the AEM gives you. They had 800 horse power in that supra and it drove like it was stock. Or so he said the video showed.

Call em up and ask the pros.

good luck,

Here is a shop that is in florida. Not sure how close they are to you but they seem to have some fast cars that are using Microtech and AEM.

http://www.centralfloridaturbo.com/index.php

Maybe these guys can answer more of your questions that I personally know I can't. Sorry I know everything there is to know about each system to help you much on your choice. But Im trying to find you some sorces that can. Or atleast point you in the right direction.

Here is a pretty sweet video of a DSM that they did also.

let us know how it goes,

Thanks for the link. I've been searching around as much as I can and I found the AEM on slowboy's site going for $1500. Think I'll go ahead and get this instead of the dsmlink that I've planned on for so long now. Couple of questions though (and rumors I've heard).

Met a guy over the weekend who's getting the EMS system and he told me that I could just download the maps from someone else who has them to make setting it up much easier. Is this true? Not sure how easy that'd be for me being that I'll have 950cc injectors and a T-67 on a 2.3 stroker. Don't know of many people with the kinda setup I'm going with to make this possible.

How often would I have to tune with this system after I get it about where I want it? I mean will I need to keep the laptop in my car very often? Guess I'm not able to use a palm when not using the laptop in my car can I? That's one feature I'd enjoy with the use of dsmlink.

And I was asking before...

Also, exactly what sensors would I need to buy. I know the 3.5 or 5 bar sensor (not sure which would be better) and 2g knock sensor. Would I need the GM Air Intake Temperature Sensor, 125 psi Fuel/Oil Pressure Sensor, and EGT Sensor (RTD Type) Kit? Does it log fuel or oil pressure? Does the EGT sensor go to my egt gauge AND the aem unit? What exactly would I need with this? Thanks!

If you find someone that has a similar setup then you could very well upload their map. But after doing so you will still need tunning as no 2 cars are exactly the same. And since youre in Florida Im sure you will have different environment variables then the other guy does. But It might be a good place to start. But just remember that their tune might not be that great and could send you in the wrong direction to making your car run its best.

Since you are in Florida I would talk to www.CentraFloridaTurbo.com and see what they recomend. But I have a few other links so you can get an idea of what you need and some install tips. So when you do talk to CFT you atleast have some sort of idea of what they are talking about and whats going on.

Here is a list of parts that is very useful in the AEM EMS.

http://www.roadraceengineering.com/ems.htm

Here the install tips that RRE has on there site. It also explains what certain features will do for you.

http://www.roadraceengineering.com/instructions/1gems.htm

Here is what I have and am going to have installed soon.

AEM EMS
AEM Wide Band
AEM Wide Band Display Guage
AEM 3.5 Map Sensor
GM AIT sensor
GM boost solinoid
2G knock sensor (OEM)

On the sensors I talked to Dan from garage_defeat and this is what he recomended along with many others.

In your case you are a 94 like me so you need to get the 2G knock sensor. RRE explains why you need this.

On the GM AIT sensor, you will need this if only converting from MAF to Map(speed density). The reason being is that our cars have the AIT inside the stock MAF.

On fuel pressure just get a fuel pressure regulator and a fuel pressure gauge that goes inside the engine bay. You will save money by going with this gauge and you can set the initial fuel pressure manually with the FPR and then who ever tunes the car can mess with the injector duity with the AEM EMS.

Oil pressure Im not sure about. Ill check into and see what we need to do. Im thinking the EMS can monitor it using the factory sensor. But unless you are going to keep your laptop open with all the gauges up on the screen then I would say you might want an aftermarket gauge to monitor the pressure while racing.

On the EGT gauge. I would say dont waste the money. Just get a wide band of some sort. This will aid you in your tuning also. And if you get the AEM UEGO then you can get the read out that is a guage that will you will be able to monitor while driving your car. Just another safety feature while also it will be used along with the AEM to maximize your tune.

If you notice I have the GM boost solinoid listed for my setup. You wont need this in your setup. The reason being is this is used to control boost during certain RPM ranges. This acts like a traction control device which you wont need since you are AWD. LUCKY!!

One the Map Sensor. If you go with it just ask yourself how boost you will be running. the AEM 3.5 bar map sensor is good for 35psi and the AEM 5 bar map sensor is good for 60psi. GM does make a map sensor that is good to 32psi but from everyone that I have talked to says they end up ditching it for the AEM and end up spending more money in the long run. I would just choose between the AEM units. If you are never going to see over 30psi then get the 3.5bar sensor. If you are going to run more then 30ish psi then go with the 5bar.

Also you might want to call up buschur racing. I think they sell an AEM kit for like 2200ish with all the sensors you need and that includes tunning. And if you buy from them then they will teach you stuff about the EMS while they are tuning your car so that way when you go back to Florida you can datalog your runs, send em back to Buschur for reviewing, and then they will tell you what you need to do to maximize your tune. But if you have CFT close to home then they would be able to help you more then anyone I would think since they know the system and what to do to make the AEM EMS cooperate with Florida's environment.

I hope this helps ya. Also if you find out any new info that we have not gone over in this thread, post it up. You can never learn to much about this stuff. Plus I would like to see what we need to do about the Oil pressure gauge.

keep us updated bro,
Josh

Oh and another thing I forgot.

On the fuel pressure regulator. Go with the aromotive unit and not the B&M unit. The reason for this is its the lines not the fuel rail that will limit your ability to make power.

back to studying,
Josh

 

[v8s_are_slow]

I have a fullthrottle fpr I was gonna use. Any reason I shouldn't use this one???

Also, I'm kinda doubting that I'll find someone with a similar setup as me unless I can find one on here and that person just e-mail me there maps or something. I may go to CFT but they're about 6 hours away from me.

Are you saying I can just trash (sell in otherwords) my EGT gauge? Wouldn't need it I'm guessing? I mean I know I'll have a wideband but wouldn't I still wanna use my EGT?

As far as the AEM UEGO, I'm seeing that SBR sells a single and a dual channel. What's the difference? I posted another thread but I'll delete it if I can get an answer here.

Not doing business with Buschur anymore (after what happened with my crank), so I'll more than likely go with CFT or something or see what I can do on my own being that I wanna know how to tune it.

We need a separate forum under the tuning section for AEM EMS specifically. I mean the forum is down and I'll end up making this thread last forever. Too many questions I may have being that I'll need to know how to set it up for starting (and breaking in my new motor), tuning, doing the different maps (pump or race gas) and switiching between the 2. And would be easier when searching for others comments on their tuning, etc.

 

[SlowImport]

I have never seen the fullthrottle fpr. From what everyone is saying if you want big power then you need the full to back it up. And aeromotive's fpr uses bigger lines with there fpr. And from what everyone is finding out its not the fuel rails they have been maxing out but the fuel lines. But since I have not seent he fullthrottle one I cant say if its good or not.

On the EGT gauge If you want it you can keep it. But if you have the AEM Wideband gauge, you can monitor the A/F ratios in the same way. If you are running lean then I would highly recommend that you not rip it. But if you are running with a good tune and and your A/F ratios are in a safe area around 11.2 give or take then if you are running this rich then it will keep the temps down. When you lean out is when the EGT's start to climb.

As far as the CDI goes. I have yet to find anyone that knows the difference. So if you find out then post it up so we can all know.

As for the AEM forum. It is up now. So maybe some of your answers can be within there somewhere.

Oh and I have yet to find any answers to your Oil pressure question.

later bro,
Josh

CFT also selling Microtech... It also a good EMS with minimal cost and used back all original mitsu sensor except for an AIT sensor to be add up if u want to.. if not it still can be tune and produce a good #s..
