let's see new ignition table.

Here is what I currently have in mine (car still not back up running).. not dyno tuned or anything, but basing it off of info I've found on here, probably a bit on the safe side.



edit: was on my phone earlier and posted the wrong table.... that's the one im still in progress making for my new low CR built motor.

Also forgot you were 1.6 guy. Here is DIY base map for a 1.6L motor with GT2560r...... probably a good starting point for you.

I wouldn't run that on my car.

On the safe side if you have a built motor

Oh yeah, I still have stock rods and pistons too.

Ok vote:

Track day on the 31st or artech 3" cat? Followed eventually by a 3" exhaust. For some reason if I want to blame something, it's not the muffler or 2.5" piping, it's the ancient 2.5" cat.

the cat is the biggest bottleneck.

with 155whp I wouldn't even want to track it lol
get the cat

Hey, it's really fun on the track.

Metal core or ceramic core? This car still needs to pass the sniffer test every other year.

metal core 200 cell.

I run 2 1/2" from the turbo back...with no cat. Is 3" really necessary for a turbo that small?
I'll upload my spark table from when I dyno'd at 225whp at like 12psi when I get home.
I'm curious to see your guy's thoughts about it.

Braineack

iTrader: (62)

yes, always.

Does no cat, a 99 vs. '93 motor, 2psi, and possibly a more aggressive spark map really make 70hp?

apples vs oranges

Big difference though

my 2.25" exhaust vs. a little porting of the head and a 3" cat/exahaust:

Great Scott!!!! That's a big difference!!!

whats funny is your "old" curve looks almost exactly like curly's

thirdgen

iTrader: (26)

I can't believe you picked up 45ft/lbs more torque...that's insane!

Scott, looks like the old curve was a good bit richer as well -- how much do you think you gained just by leaning out the tune?

Braineack

iTrader: (62)

IIRC both were tuned at 12:1, so take that with a grain of salt.

But yeah, other than fuel tuning, nothing else changed. Spark exact spark map, boost level (although it had a bit of creep), turbo, manifold, dp, etc etc etc.

.5-1 AFR won't bump it up any more than 5-7whp. 10 in some bigger setups. at least from what I've seen.

Bust the guts out of the cat you have and go to the track day. Then, before your next sniffer test you can buy a new cat and swap it in. That way everyone wins... except the planet.
