ISO9141-2, and real time readings? Not so much. The ISO standard will only kick out about 5 individual readings per second, not 5 complete sets of parameters per second, 5 individual sensor readings per second.

99% of the questions that are "STRANGE" have a dirt simple answer...usually answered by a dirt simple search.

NISSAN GOOGLE

Is it just me, or does the majority overlook the obvious?

Somebody ate a whole bag of dumbass for breakfast.

Why do people continue to run a vehicle when a warning light comes on or starts flashing? Isn't that a clue that something is wrong and you probably should NOT drive it?
Is this whole car driving thing really freekin' brain surgery?

Here's something new for the crowd/clowns...
"A little bit of Google goes a long way!"

Ever notice the one post wonders for info on turbo'ing a GA16 are never heard from again after they figure out the cost???

And if you can read this, you don't need glasses! :)

And yes, I am diggin' it...

so what would be better, the Nissan 14 pin connector or the OBD II. I just want to see a couple of live feeds for diag purposes and some slight tunning.

Couldn't tell ya.
One thing I do know, "slight tuning" very "slight" tuning, is about all you'll get out of an otherwise stock GA16DE.
This ain't your grandpa's SBC350.

Do tell your grand plans to tune the engine...

Based on my experience with my 97 Sentra (A/T) and 98 200SX-SE (M/T), both with the GA16DE, your right foot is about the only thing that'll help you out with any real effect.
Past that, maybe you might get away with bumping up the base timing a couple of degrees, at just short of the point of pissing off the ECU depending on what gas you normally run. Some guys swear that they'll add 10degrees and run premium and get an extra 3MPG. How is that saving money? It ain't. A few degrees might help for now, but any gains will get negated as soon as you put that first tank of bad gas in it or the temp warms up and the engine starts running on the ragged edge of pinging again.
Put a cold air kit on it, and keep the ECU from going into closed loop for longer than it needs, and waste more gas. Or go ahead and try, and be disappointed at all the money wasted.
Put a fart can muffler on it, and not get any better gas mileage, and piss off your neighbors from all the extra noise.
Cut the cat and spend the extra money trying to compensate.
Put in aftermarket quad tip iridium dual firing monkey-wrenchin' left-handed counter- clockwise firing fat-free low calorie spark plugs...and replace them 5 times as often, and not gain any fuel mileage.

I've gotten a consistent ~35MPG in my 98 200SX (high 50's tooling around Yellowstone Nat'l Park), low 30's in my 97 Sentra (mid-20's with the wife driving). I've got a very light right foot, keep the weight down in the car, keep it well tuned up, and so on.

Major point is that these engines run great in their stock form. Any savings in fuel and $$$ will surely be negated by having to buy that new engine and/or car after a person messes with it to the point of no return and ends up burning something up or breaking something.

hmm. I get a pretty consistent 37-39 mpg in mine, but I work with/around 300hp cars all day, and driving home in my econobox gets old. I like saving money on gas, but if a can get a bit more power, and a bit more fun out of it, then it might be worth the increased cost of premium. I typically don't mess with my econobox daily driver other than to maintain it, but i'm getting a taste in my mouth for some performance tuning. I mention this because i've gotten whifs in a few other threads that you, jdg, have messed with ignition advance. I would like to try it on mine with premium gas to see if i can get any performance gains, but this picture you paint ain't pretty.
Please go more in depth about your experience with adjusting spark advance. I would love to know others' experience with adjusting this on the ga16de before i spend a saturday afternoon playing around with this to no avail (which, granted, i will probably end up doing anyway because i can't just take someone's word for it)

Entirely too many variables to compare your 37-39 MPG with my ~35-ish. Highway, temperatures, stop lights, hills/valleys, speed limits, altitude, fuel quality, driving habits, the list goes on and on.
Yes, I've messed with the advance a bit, in both of them. I tried an extra ~10 degrees for a season (18BTDC total?). Worked ok in the winter, as soon as it got warm out, pings left and right, and putting in premium negates any fuel savings. Backed it off for an extra 5 degrees, ~13BTDC. Better performance, but still pinged, and on hot days would even run on occasionally.
Did it run any better with the extra timing? Well, maybe it did, maybe it didn't.
I place exactly zero stock in the "butt-dyno" that every 16 y/o loves to quote.
Maybe it was a bit quicker coming off the lines at lower rev's...maybe not.
Maybe it lost that same amount at the higher rev's because it was firing just that much earlier...early enough to build maximum dynamic pressure before TDC, but not early enough to make it ping...and thereby lose power.
Are there products out there to make the GA16DE faster/better/stronger/quicker? I'm sure there are. Can't think of brand names off the top of my head, but I know there's a company out there that'll sell you a reprogrammed ECM, probably mapped for your mod's as well.
And again, OBD for datalogging, yep, it'll do it, at ~5 sensor readings per second. Not nearly enough for any really good data interpretation.
Nissan Consult might do it faster, might not. Don't know, never used it.

what i was getting at, is that i'm getting good enough gas mileage that I'm willing to sacrifice a few to get some more ballz outta my 1.6. Being winter, I think i'm going to go for it with some premium gas to definitely negate the gas savings.

gotta wait till i can fill with premium, though. i still got 3/4 tank of 87.
