Thread: vvl swap help

Money is sorta limited right now yes but hopefully it picks up soon
I'll look at the nistune. Is it like a basic chipped ecu? Cause i wouldnt know how to tune myself

Dude take it from me, another b14 with a ve, nistune. No jwt or crap, spend the right money, get the right product, nistune all the way. And dont cheap out on the window switch, i did, and just bought a new msd switch which works SOOO much better.

I wish i would of noticed this thread and stuff when you started, i would of chimed in some througout, but i just noticed it today.

Okay yeah i was gonna get two msd boxes with the pills.
Is the Nistune chipped? Cause idk how to tune

Need some help, its driving me nuts
Okay so my idle is at about 800rpms
There isnt a air or vacuum leak anywhere
The car increases speed like crap and lacks alot of power (without vvl)
When i put the car in nutral (coming to a stop) the idle drops to about 550-600rpms and sometimes in parking lots reversing and pulling forward slowly the car will die.


The TPS voltage is right and the ignition timing is correct.
My idle screw was tightened all the way just to get it to idle right and the other idle screw is closed too. So i opened the idle screw on the IACV and the car idles higher and has alot of power and doesnt lag on acceleration.
And then last night without touching anything the idle wne t down again and started to act up and then finally picked back up after i pulled over.

im out of ideas please help!

Mine dies in the morning at the stop sign by my house. Every time.
The nistune runs off a cable to it laptop. So u can live tune it. No chips. Program cost extra unless u find a place with a dealer license so they can constantly tune as many as they want. Unfilled menu goes for our cars its the best u can get. I paid 425 for my exult and program. But worth it.

Idk how to mess around with all that stuff lol. Was looking for a basic

The Nistunes can be loaded with the proper BIN so you can drive it just like a Basic, but you can realtime tune it whenever you want. So don't let that hold you back. If you have your Nistune board installed through an authorized dealer then they can load the appropriate BIN for you so it's plug and play. Then later on you can either buy the software or take it to a dealer for fine tuning once you get additional mods.

btw, make sure you're adjusting the idle with the car in timing mode.

Like ser96vspec said, you can get a tune loaded on it and call it good. Its just better to have, because if you upgrade with n1's, or do anything else like bigger exhaust, you can adjust to get a lil more power.

Did you go through the process I posted a while back? Timing mode? If so was the car completely warmed up when you did your adjustments?

Also, do you have any DTC's? (engine code issues/ CEL) You may have an IACV issue. Have you tried to remove the IACV and clean it out? There are only a couple of screws and a thin gasket (<--handle with care) to remove to check the condition of the unit.

Have you load tested the battery or the alternetor? You may have an issue there. This would affect idle if you are not in gear and under load. Turn on a bunch of accessories, defroster, high beams, heater fan etc. does your idle become erratic and unstable?

When your car is warmed up completely and idling, is the fast-idle adjust screw far away from the throttle stopper or is it close to it?

Check these areas. It is hard to know what your issue is for sure, without being there. My best tool for fixing all of my car issues has been an insane amount of research and reading.
