Is a good thing to have in your tool box .fom the transmission to body electrical to the engine ,navigation lighting .if it have a on and off bottom you can control it any sensor any valve or injector, window ,speedometer and the best one speed restriction on or off.

Ive been looking at this for a while but was unsure which online vendor (whether on ebay or other) ships the unit with the 2.27 disc. Can you lend a hand?

Let me start by saying I've been researching this heavily on the forums over the past couple weeks. Aside from stage 1 cams, this is the last set of modifications I want to do to my car, as you can see in my sig I have the rest of the main bolt-ons already.

What I've noticed is that we have a lack of dyno charts and overall lack of experience on this because of how new the 3.7 manifold is to our 3G community. While a few people have done up some great PnP stuff over the past few years like Andy, Anil, and Sonnick, I feel like we're just now picking up momentum and visibility to the 4G manifold option and only a select couple people have done it.

That being said, I had a long talk with the service manager at King Motorsports this morning. They are very local to me (about 5 miles away). They were a bit dismissive when I first started talking to them, citing that the j-series doesn't get much out of PnP without headwork unless you can port the whole Intake manifold. That's the reason their website only offers a bored TB solution and TB/IM port matching for j-series, but nothing more. Once the guy realized I'm not a complete idiot, though, he changed his tune as we started talking specs and considerations when doing intake work.

So because I need to have my car running as my daily driver, here's what I'm going to do:

Today I'm going to order the 3.7 manifold and ZDX TB. Once they arrive, I will install and take it over to King for a dyno chart with no modifications to the mani/tb. I should have a good point of reference for how much power they will gain because I was dyno'd just 2 months ago and still have all the same mods. Makes me glad I did that because otherwise we would have no idea how much power was from those vs. all my other mods, lol.

In the meantime I'm gonna try to source a spare set of stock runners, so if anyone stumbles upon a set for my type-s on the cheap, let me know.

After dyno and I have a spare set of runners, I'll re-install my stock parts and I will be working with King to get the spare stock runners, the 3.7 mani and zdx TB on their bench to figure out how it can be best optimized.

Obviously I want my car to be faster, but my other goal in this is to clear up some of the bullshit on the forums. I see a lot of people who are incredulous of the potential gains of improving the overall intake and flow of air combined with good exhaust mods, short of headwork. I want to see for myself what the j-series can do with comparison dynos and the final word from a reputed shop like King Motorsports.

Brock or rubenders,

Ive heard that at some point when the SPX MVCI came out (after v2.019.011), the software started calling home and if it wasnt a legit copy it would lock down. Is this true?

the only problem with that is keep an eye on the knocking.....if the ECU "think" its cold air coming in and advances the timing too much and if actually hot air is jumping in your cylinder, you will get some serious detonation....

I have my sensor relocated as well....and yes ~8-10 in the city and 3-4 on the highway

I have had the 3.7 mod with a 4" intake since almost 8 months now...if i remember right, i swapped it in spring 2012....did the IAT relocation around that time too....am using torque pro to log the timing advance/etc....havent installed the MS3 ECU yet...that will log the knock monitor

it takes the ECU a longggg time to adjust...my AFR didnt go below 13.5 even on WOT for almost a month after the mod....now it dips down to 13.1-13.3 @ WOT and 15.xx while cruising...

well in torque you have a logging option....go in there and select all the parameters you want to log....it throws out a CSV/XLS file which you can open in Excel.

You can transfer the file from your device to your computer....zip it up and add it as an attachment to your post on Acurazine

Confirmed that HDS 2.027 does not call home (via packet sniffer). Don't know about the MVCI though as I have an HIM clone.
