Re: differential ratio - I'm running a 3.46 LSD. If you're ever going to be across the border in MI, we can meet up so you can see if 3.46 is right for you.

There are a thousand things that can make your gas mileage bad. You could have a bad sensor on the motor or your FPR gauge could be off and you could still be running high fuel pressure or whatever.

The last thing you want to do is trick your ECU. Just make sure it's getting the correct info it needs and you'll be fine.

And if you're getting soot on your bumper, get a cat.

No O2 sensor simulators.

Do you have cats?

no...i might have to get one though for emissions testing.

[SpecM]

No O2 sensor simulators.

+1... you want the DME to know what's going on in your engine

[matt]

lol thats why i asked, might look better if the needles are red.

Matt, i switched the o2 once already im positive its working, what do you think if i played with the fuel pressure lowering it a couple psi at a time till i dont have a black tailpipe? this thing is burning premium fuel like no tomorrow.also...can a o2 simulator do anything for me?fool the ecu?

And first will be utterly useless.

3.25 will be probably your best bet...I on the other hand will be shortening it up to a 3.46. 8)

D did i mention im at 1500rpm...at 60, in 4th, looks like im at around 2500rpm on the highway, should be pretty good on there.

You mean with the 2.93, not the 4.10. With the 4.10 you'll be doing around 4500 on the highway.

[QUOTE=BigD;1138623]Try it on the highway first... it'll get old fast. Even on the track, having to hunt through the gears or hitting the r3vlimiter just past an apex will get old just as fast as a 5k rpm roar in your ears on the highway.

I kind of like the carbon cluster & chrome rings - but those white faces have GOT to go. Way too rice, like Altezza's and coffee-can exhausts. Yuck!

heres a couple things i did, carbon cluster and chrom rings, i was going to paint the needles red, you guys think nail polish or paint marker? i was going to ditch the white faces, yay or nay?

Matt(racersmarket) technical question for you, a friend of mine keeps babbling that your chip might be the reason im lean, or his theory is that the computer "thinks" its running lean as my gauge shows and dumping fuel to compensate. the only thing that could tell the ECU that its running lean would be the o2 no??? im starting to think that its because of my o2 positioning inside the header, should i relocate it to see, or do you know for a fact that someone has run the o2 inthe header with no problem.

Your car is not running lean... your wideband can't be trusted, you know that. You need a stock, working O2 sensor somewhere in the exhaust. Your wideband may have a narrowband output... that won't work.

You can put the O2 sensor almost anywhere you want. Yeah, it's better to see all 6 cylinders, but it's not critical.

im going to search for the 3.25, now that i no what it came in. i think i might start a diff collection! i dunno D i kinda liked driving at 60km in 4th gear and still having balls galore, but ill see what i can find first, i think i might show at importfest with my pink paint!

Try it on the highway first... it'll get old fast. Even on the track, having to hunt through the gears or hitting the r3vlimiter just past an apex will get old just as fast as a 5k rpm roar in your ears on the highway.

Here's my cluster view :)

[OoPEZoO]

I think the white faces look fine, but I would definitely do something with those needles. I tried a red marker and nail polish on mine, but both turned out funny looking. You could see streaks with the marker, and the polish turned out extremely shiny and looked out of place. I went back and repainted them using a flat red model paint. Now they look good. They fit right in and you can't even tell they are painted.

[windsor318is]

good old fleabay!

[e30s52]

where did you get the carbon face for your gauge cluster?
