So now that headers are in and i have to wait for new raidiator fan, i been looking at widebands. I plan on getting vafc2 just want to know whats the best wideband to go with it. I dont know much about tunning so i plan on having someone else do it any hell is great!

 

Get the Innovate LC-2 fully digital and very accurate wideband,I'm using one in my boosted 240sx for 2 yrs now

 

Get a rear mount turbo! Fuvk it!!!!

 

I like innovates gauges alot! Just need to know how important is it to datalog and rpm stuff. I understand the concept of a wideband but is it needed if im not tunning myself? Cuz to me its seems like it just a gauge


I always think about turboing the maxima but idk

 

Subscribing.
I have modded mine and have a vafc2. Haven't installed it yet. Still need to get a wide band o2.
Plus I am really wanting to do the 4inch intake and nwp throttle body.

 

If you're having it tuned you may not need the wideband.

If you're taking it to a dyno shop they'll have a wideband that reads from the tail pipe. If you're just having an air/fuel tune on an NA car there's no need to monitor it after that.

If you're going to have someone street tune it you may need the wideband since they probably won't have a lot of equipment.

Either way, on an NA car it's just another gauge. I have one but the gauge is tucked away by the ECU along with the VAFC2. There's no need to look at either of them once the tune is complete.

 

Very helpful! So basically this talk of datalogging rpm and a/f is just for peope who tune themselves. Which i dont know enough to do so all i need is a vafc2 to tune it at a dyno?

Same here im in talk with cgr avlut the 4" i will be buying vafc2 very soon then gtr injectors and then hopefully tune it! As for the TB im not sure yet seems high to me i have to check dynoa of people with similar mods and a 75mm TB

 

Exactly. Once it's tuned there's not much to do. Gauges are important on a turbo car for several reasons. On a simple NA car there's not much going on to worry about.

Depending on when you're planning the 4" intake, you may want to wait and have it all tuned at the same time. You can run the headers untuned and it'll run a little rich at high RPM. No problem.

You'll really want to tune immediately after the 4" intake/injectors no matter what. It might make sense to put the cost of the extra tune into bumping the 4" intake ahead of schedule and only paying for one tune.

 

cams

 

I am going to attempt a street tune. Never done it myself either though my girlfriend tuned her last car herself (she built a custom turboed 93 ford Taurus SHO. 500whp)

So I have help if I need it.

 

Just to clarify you will need a wideband to attempt a street tune. On a na car it's pretty basic you can't really mess up to bad. I sure there's been cases but you would need to do something very foolish. I've made some dumb mistakes on my turbo max and got a way with it with much slimmer margins for error.

 

Welli plan on getting vafc2 first then ordering the 4", the injectors and maybe the TB body as money goes then installing all those at the same time and getting it tuned

Why cams?

 

Good plan. You should be able to install the TB anytime without having to retune. The adapter plate from Aaron is a bit pricey but it's a very nicely done piece.

I'm pretty sure Donkey was joking about the cams.

 

Wish I could afford cams.

 

Strange GTR injectors, a 4” intake, and a WB weren’t mentioned as a combo, along with a test pipe and 3” exhaust. I am still sort of on the fence re: the 09TB just mostly because of the price.

Also, as a side note, headers were my first mod actually, so many many things came after headers for me.


IMO Cams $:result ratio is not as enticing as an HR swap.

 

So gtr injectors plug right in? Do I really need that large of an injector
? They are 560cc

 

Please read the 4" intake thread. 560cc gets the AFR very close, so the car is easily tuned with an afc and no timing is pulled.

 

Im in touch with cgr for 4", where do you guys get your injectors? And what test pipe is recommended? BTW i agree with the price on both cams and TB. I doktn know the cost of an HR swap but i have seen them and they are nice af

 

So is the tuning basically an update/reprogram to the ECM?
I'd say if you don't get that it could damage a circuit + driver but exactly which one?

 

He better ****ing be making them correctly, now.

 

CGR will get yo injectors and the intake. Those injectors go for about 180$.

 

No it tricks the ecu in order to make adjustments

Oh nice i checked admind tunning and they were $200+

Lol i sure hope so
