Tuning after FMIC install

[vr41mpg]

Hey my car has a base tune with V3 ECMLink that was done by a reputable shop over a year ago. I just bought a used ETS FMIC kit and a 63MM NT Throttle Body. Is it safe to install this stuff and drive the car without tuning it? What if I lower the boost? I just want the car to be safe for a daily driver.

Will it be easy to compensate for these parts myself with ECMLink? I was a bit overwhelmed by the whole tuning thing but maybe since it already has a base tune, I would only have to compensate for the extra air from the FMIC and TB, right? From my basic understanding of this whole thing is that I would just have to add some fuel? Would I have to adjust timing? Would be simple enough to not have to pay someone?

I understand that I am able to up the boost from 16 to 22 psi after installing this FMIC, however I dont care about doing that right now. I just want to have the car drive safely daily.

Thanks guys

If you have a wideband you should be fine just keeping an eye on it.. usually the FMICdoesn't make a huge difference in AFR"s but being that i dont' know what your past cooler was and what sort of restriction it was causing you at your boost levels it's really hard to say.. You COULD end up moving a good bit more air and going lean or you could just end up with slightly denser air still causing you to be a little lean.. Either way i wouldn't beat the car hard wihtout a wideband 02 sensor to tell you where the AFR's are sitting

do you dd your gvr4? i just picked mine up a couple weeks ago, waiting on a few parts and some free time and ima be on the road.

yeah im sure you will have to adjust a few parameters after installing a bigger tb and ic. the motors getting more air, which can cause it to run lean, causing knock, possible boom. other crap like the tps, etc have to get set yaddi yaddi yadda. im sure link makes it easy to tune, maybe some one more knowledgeable on link can chime in.

If you're still using the stock MAF sensor, all your couplers are tight (no boost leaks), and you haven't turned the boost up, your tune really shouldn't change.

i daily drive my car. i currently have the stock GVR4 intercooler which is very restrictive and I was told got heat-soaked badly when they tuned it, and had a slight leak during the boost-leak test. so I definitely think I will see huge gains from this because i have alot of other supporting mods already.



what if i were to just install the rebuilt 63mm NT TB? Can I get away with no tune? On the throttlebodys.com website it says I will have to adjust the idle with my aftermarket ecu. That sounds very simple, is it?

scratch what i said, knoch is right. adding a bigger tb and ic will open's up bottlenecks, this is good. Air moves through the maf first, so your current tune will hold up assuming like knoch mentioned the maf belongs to the tune and boost isnt turned up.

if possible get a before and after log as i would like to know what the drive characteristics ov those mods are.

install both items, run a boost leak test. then adjusting the tps, throttle cable and possibly the biss should be a cinch with v3, and there is plenty of coverage on both ecmtuning and dsmtuners forums.
