Yes I beleive the AEM EMS is the system that most of 3000gt VR4/ StealthTT owners that are serious about modifying their cars should eventually go to. But the WHOLE setup to run AEM with speed density and a wide band o2 gauge will cost about $2000.00 You can have your ECU repaired for about $230.00 or buy a REBUILT ECU for about the same. You will need a lap top if you go AEM so you can factor that in as well. And it will take hours of tuning also. The manual is 230+ pages long. If you repair your ECU or get a rebuilt eventually when you are ready for an AEM the stock ECU could be sold. But IMO the AEM is a performace up grade and not a quick fix for a bad ECU. If you look on www.stealth316.com it has the name and addresses of the placed that can fix your ecu. "I think" Avepro is the best one if I remember the name correctly.

i applogize for the misunderstanding..

i fully plan on tuning the car.. thats the entire point of me wanting to get the AEM since my stock ECU is shot..

its just that i'm not going to install the AEM and immediately start tuning the car.. my only concern right now is just getting it back running and "drivable" (and by "drivable", i just want to be able to drive it back home from the shop.. lol..)..

as far as tuning, i'm still in a learning stage.. but tuning was the primary reason why i bought the car in the first place..

again, i appologize for the misunderstanding.. i'm not going to buy an AEM and do nothin else to my car.. that doesnt make much sense.. i just wanted to kno if it would get my car up and running again so i can prepare for future tuning...

you would not want to drive it far on a base map. a few miles from a shop, maybe. but I wouldn't. you may be able to dig up a map from someone else that started out with the EMS and no mods, but that may be a tough find.

get AAA and tow the car home. buy the EMS, the sensors you will need to really tune it, and do it right. if you plan on future mods like turbos/exhaust/injectors/etc, then I think you get the most bang for your buck with the EMS.

so I guess I'm not clear what your questions really are. If you want an AEM setup, figure $2k + laptop + hours of time tuning.

or figure $2k + shop install time ($$) + shop tuning time on a dyno ($$) = driveable car.

cool.. thats a good way of looking at it.. thanks for the advise..

honestly speaking, if i could get the AEM to run at a level consistant with a stock ECU, i'd be satisfied a the time being.. like i said, the car is a project in the works, so reading thru the 230+ page manual and potentially spending hours and hours tuning over the weekend(s) is something that i wouldnt mind doing..

thank you guys very much for the clear input and whenever i decide to get an AEM atleast i now know what i'd be getting into..

well, to kind of change the subject, what brandname wide band O2 gauges would you reccommend?..

and this question may have been asked earlier in this thread, but what is meant by "speed density"?.. what all goes into setting that up..

Speed density eliminates the MAS and all of its limitations. You need new intake pipes about $200 air intake temp [AIT] sensor and a manifold air pressore sensor [MAP] around 200-300 for both together. My car has a AEM [brand] gauge type wide band o2 sensor about $450.00. It is a gauge and a sensor and can talk directly to the AEM computer. Other wide bands O2 can also be used some have gauges some don't.

the AEM brand gauge sounds like the way to go..

here's another question.. i'm following you on all the sensors (i'm also taking the time to read the AEM FAQ someone posted earlier) but what's the significance of getting new intake pipes?..

Speed density is basically what the name suggests... The engine management is converted from Mass Air 'flow' to an Air 'density' measurement. Instead of a MAS or MAF sensor to gauge the air 'flow' coming through some filter/sensor... it is replaced with a sensor that will read the Air 'Pressure'.

Also, since the MAS also houses the intake air temp sensor... you need to rewire the stock IAT with an aftermarket.

just trying to beef up FastOldGuy's answer.

you don't need new intake pipes...

you don't need to get new intake pipes to run speed density. it would be silly to not upgrade the pipes. but it's not required.

you can run the map setup, with the stock mas sensor installed, but disconneted, and the stock filter or k&n or whatever still on there.

with stock turbos you probably aren't seeing too much of a restriction with the mas sensor in place. but it's one of those things that wouldn't make much sense to keep around if you don't need it. it's only going to hinder performance, maybe not right away, but probably once you start some upgrades to the car.

You are eliminating the stock mas and intake pipes the Rubber thing that holds the MAS and the rubber pipes that run from turbos up to the MAS. Most people replace them with intake pipes and filters. This is what they look like from www.Dejontool.com There are others that make them also. This is just one example.

i love those pipes man.. i was going to be in the market for new intake pipes once i got done with the exterior customizations..

i think i'm sold..
