You need a management system that is compatible. ECMLink v3 is one (I think only the full version), and AEM EMS allows it too. I'm unsure if ECU Flash allows it as that I'd another great choice to go with since you have the 98/99 black plastic flashable Ecu.

You'll need a MAP sensor and it really helps having an IAT sensor. The link posted above will let you know more about what is done to run off of those sensors.

You can use ceddy mods/ecuflash for SD.

Mods/Wisemen, please correct me if I'm wrong, but how speed density (from what I read) is that it uses sensors on intake manifold to figure out how much air it is drawing in rather then using a MAF. Using speed density allows you to eliminate the MAF, however you need a way to tune this. ECMlink, ECUflash/Ceddymods, AEM EMS, etc. are all ways to tune but you have to find what works for you. From what I read, there's a CRAPLOAD of support with ECMlink+SD more than anything. I know VERY litle about ECMlink, but I can let you know about ECUflash

You said that you have an 98 GSX. That means you should have a flashable ECU. To confirm this, take off the kick panel and check out the ECU. If it has a black box, then congrats, you got it. Also check underneath the dash where obd2 plug is at, there should be a little white connector behind the obd2 plug. If there is, then in order to run ECUflash, all you need is the following: Tactrix 2.0 cable ($50-150), reflash connector, ECUflash (free), Ceddymods (free), and Evoscan as a data logger ($20-50). Here's a nice beginner's write up for tuning with such software: http://www.dsmtuners.com/forums/articles-tuning-ecu/407715-how-get-basic-tune-ecuflash.html

I second the ecmlink suggestion. I went from gm maf/maft box and chip to full V3 with SD and have not looked back. There is a big learning curve but compared to "other" systems out there, this one is by far the easiest. If you can play a video game, this is not much more complicated. The great SD feature apart from power it produces is its forgiveness to leaks etc. Ive been stuck without tools and with things popping off etc, and have managed to able to drive back home. It certainly makes the engine bay look alot tighter too.
Complete pkg, ease of use, unequalled support on their forums, probably same if not more help here on our forums, and cost effective.

Yes! the car has 98 black Ecu and i Would like doing speed density on it if it will allow it and as far as the white wire do you know if anyone has a picture of this? can i use the cable from dsmlink to connect this?

Thanks for the help
