There are allot of talk on turbo cars or supercharged but what about NA?

Which piggyback or ems would you use? and why?

I would like to be able to add a turbo in the future though.

my car is OBD2.

What gains would you expect to see from a stock ecu setup with good set manifolds, exhaust system and induction kit.

That's my setup, not sure on the bhp obviously it's running on a stock map on the orig ecu, if i was to get an aftermarket setup what gains would you expect to see as then i would get the best out of the parts i already have.

I also have a snow performance water/meth kit sitting at home to go on also.
 
Are you planning a crazy N/A build? Something like 12-13:1 compression, ITB's, big displacement etc.etc. ?

If not, I don't know what you might hope to gain with an EMS and water/meth kit.

Keep in mind the AEM FIC will only retard timing, not advance it so for N/A it may be limited.
 
Thanks for the comments.

Actually Angus, i am looking at your turbo kit. Was thinking about going ahead very soon but i might wait until later in the year for when i take it back off the road for winter or when the pound gets stronger as it will be cheaper.

But in the meantime i'm looking for a little more power and i appreciate it wont be much but my main gain is a perfectly setup car. As we know ECU is generic from the factory, exact same maps and every engine is slightly different. I now have a few basic mods which i think the car will benefit for a good tune with those mods on to get the most out of them

There is a good Chip maker in the UK which claims to give 10-12bhp. They are a good company and been around for a long time so there is probably some truth in their chip. However same as the oem ecu it is a generic chip all cars are slightly different and that chip would of been done on a stock nsx so with my mods it would be slightly different. with a decent engine management and an good tune i'm hoping 15bhp maybe little more.

Basically i just want the car to be running as sweet as it can be and putting out as much power as it can be on the setup i have.

I Will be going turbo in the future which will require some form of engine management so i'm going to do the engine management now so i can benefit from a good tune so the car is running perfectly and when i go turbo i can fit it and take straight to the tuners for the map to be adjusted for the turbo.

The reason behind water meth is because bascially i have a kit already, it bought it for a 300zx never fitted it, so might as well fit it to the NSX ok it's not as efficient as NOS but it is safer than NOS and be good for the car. I also have a HKS twin spark amplifier i might fit and once again i have it for a previous car still brand new so might as well. That wont give me any power i doubt at all but a better spark surely is a good thing.

Is there a good Stand alone option for OBD2 cars? as one tuner i spoke to said i can have a AEM EMS but i thought they were only for earlier OBD1 cars.

going back to your questions it's not going to be a crazy N/A build, just few basic mods. Downforce induction, big bore throttle, Cantrell manifolds, STMPO messiah, so just wanting little more before going turbo and something that will work well with a turbo so i can just remap it when i've had a turbo fitted.

If the AEM FIC only retards it, isn't there a better engine management option? i know there are loads about like Greddy make one and isn't there a good stand alone option? Apexi maybe? HKS?
 
I make a Stand alone system for OBD2 DBW cars. It consists of a modified AEM EMS and a custom Plug and play harness. The stock computer will stay in place to run the drive by wire and the AEM EMS will take care of the tuning of the engine. You will have full tune ability over the engine for turbo/supercharging, all motor Ect. If you are interested feel free to give me a call at the shop. I also have a modified map that I supply with the system for a 3.2l nsx with headers and exhaust

Mine is a 3.0.

As it works in conjuction with the oem ecu does the traction control still work and other things like that?

Would you say this is a better option than the AEM FIC piggy back option?

What are the prices?

How is it modified from the orig AEM? and is it based on the latest generation of AEM EMS or the 1st generation.

thanks.

Unfortunately you will lose the factory traction control but there is traction control in the aem EMS

yes this is a better option than the fic because you have direct control over the engine v.s. having to modify signals from the the stock computer which can sometimes give undesired results.

What are the prices?
For the Modified AEM EMS and plug and play harness with boost option+modified start up calibration this unit is $2395

I use the latest AEM EMS for the 91-94nsx. I have to make internal mods to the AEM to accommodate for the stock computer to work in conjunction.
