Ok please help me out here. I am wanting to clear things up.
From what I understand from researching and also being told here on
dsmtalk.
From the factory, My 95 OBDII GSX (2Ga gsx)

I have heard that,
Cruising around its 14.7 a/f
WOT its 9.5 a/f

That its setup 30/70
from 1-30% throttle its 14.7 a/f and 31%-100%
its open loop 9.5 a/f

Im just wondering how its tuned and setup from the factory.

I plan on getting DSMlink to start learning to tune with a wideband
on my stock setup and was just wondering how how the car is stock.

Thanks

No ones thrown a wideband on a stock eclipse?

Why not?
If im going to be tuning with dsm link. I just want to know
where the ecu is to begin with. Its just something I have been wondering.
No big deal or anything. Just Curiouse I guess.

Why bother trying to replicate the stock ecu tuning? They are very rich from the factory and more power can be made by leaning them out and adding timing. If it was me i'd get a bit leaner ratio and tune the timing until i knocks, and then back it off a bit.

Im not going to replicate the stock ecu,
Im just wondering what it is before
I start tuning. Just one of those things...
I know they are rich and need leaning out but It was just something I was wondering...

It has nothing to do with how im going to tune.
It is simply a question I was asking myself and wanted an answer to.
I was just asking myself, How did they decide to tune it from the factory...

They tuned it from the factory to be safe.. They tuned it so that if people dumped in 85octane it wouldn't grenade itself. They tuned it rich from the factory to safe their asses.

forget it. I understand why they tune and that they tune pig rich.
I wanted details because thats the kind of person I am.
I ask questions and want DETAILS about stuff.

Forgive myself for asking such a question.
Mods may delete thread.

Wow, lay off the guy already. He asked a simple, valid question.

Ive been working on DSMs for years and I dont know what exact AFR they are tuned from the factory, but have only heard/read anywhere in the 10:1 are and as rich as 9.5:1 in spots.

LOL..seriously... I think that you guys should carefully read each thread before implying anything. Your best bet is to hit DSMchips.com and ask Jeff for deeper inputs, as many variables can come into play. There is nothing wrong with this thread, as a DSMer and tuner... I don't believe your question is out of line or inappropriate.

Well thank you.
I'll check out the link and see what I can find out.
Edit: Says it's under construction. I'll continue to check it daily.

Thanks again!

The site always says that when you go directly to it, go to google and search for dsmchips, then click the page and it will load up just fine.
