Anyone willing to help me street tune?

shadyonedeath · 08-11-2009, 01:37 AM

Im still holding off on the 00vi swap because i don't want to drive around to school this fall untuned and rich... I dont have the money for a whole wideband kid, but i got a 60$ bosche o2 wideband sensor that works with Lc-1 units.

Anyone wanna help me out for a couple hours by letting me use their wideband reader?

Thanks, basically just need a RPM reader.

First of all, what are you using to tune? No one is going to let you "use" their wide band...your best bet is to take it on a dyno and have them use a tail pipe sniffer and have THEM tune it for you...

Second of all, your car will be perfectly fine without a tune after your 2kVI...ur ECU should be more than capable of making adjustments...Of course if you want to get it PERFECT you would want a tune, but its not necessary...

Plenty of people run an 00vi untuned. You will definitely benefit from a tune, but it's not necessary.

^ +1 again...

If you really want to get into tuning, you really want to invest in a NICE wideband, the AEM UEGO A/F guage is cheap and is really good for the price. I have been running it on my max for the past 2 years + with absolutely no problems. It runs about 3-400 bucks if i remember correctly, there are alot of other options out there as well..but this is overall the bigest bang for your buck...

But like i said this is all useless equipment if you dont have anything to "tune" with...

LC-1 wideband, i said it in the first post.

I read your post...

You still haven't answered my question, what will you be tuning with? You cannot tune with a wideband alone, you need something like a SAFC or EU..etc...

You also mentioned you just need an RPM reader? Y?

the wide band will allow you to read your A/F ratio so that you can datalog and make tuning adjustments with whatever unit you are using...(maybe one of the examples i stated above?).

If you plan on tuning, its a must that you invest into buying your own equipment...

Whoops. Its a VAFC 2

Also, the LC-1 doesn't show RPM's, it only shows the A/F ratio. Thats kinda how they get you; make you buy another component to read the rpms. (lm-1 i believe?)

Yea i know its a must, im just broke cuz of school right now. I really wanted to get the 00vi in (everything is prepped, painted, cleaned, etc.) and just tune it to avoid running rich and wasting gas.

Thanks

It'll run rich in open loop (WOT) so if you're afraid of wasting fuel then just cruise till you're able to tune the car. Closed loop takes feedback signals off of the O2 sensors and MAF to keep your AFR as close as possible to 14.7.

Yes it'll run slightly rich but it's nothing to worry about. Maxima/VQ fuel maps tend to be rich-ish from the get-go, and I haven't tuned my car yet and I haven't noticed a massive decrease in fuel mileage. For the record I have headers/exhaust and my car's AFR is 11.9 at WOT, dipping to 10.9 at redline. That's rich by any N/A standards and I haven't had any driveability problems.

Cliffs: You have nothing to worry about.

seriously? man..i was so intimidated by the "A/F rich" warnings, this things been sitting in my room looking all pretty. I guess ill start on her soon. Im still debating getting the obx headers and just doing everything while the USIM is off, all at once.

Thanks

VAFC 2 doesnt record RPM??

I can pretty much guarantee without a tune you will not notice a difference AT ALL in gas mileage...IF you start gunning it and doing WOT runs all the time, then yea...as with any intake or exhaust mod to be honest...but still very minimal...

Just do it and get it over with...

you wont regret it!

Vafc2 does record RPM but not to the lap top, which is where the LC-1 will record its a/f map. Unless i ghetto rig a camera facing the Vafc-2 while doing some WOT runs and match it to the computer, i won't know when exactly my rpm and a/f is at.
