The Injen intake is the only one I have not personally tuned. I have done both AEMs, CIA's CAI and SRI, a few different airbox mods, drop in K&N filter only, Dejon's SRI, K&N's SRI, Hahn's CAI and a few custom CAIs and SRIs. I do not know if I forgot any LOL.

 

the Home depot intake :P

 

I have done a few "custom" intakes. I have not seen any of these in person so I do not know what they were made with probably that spectre stuff they sell at the auto parts store.

 

your car wont blow up dont worry mna, just dont do your own research, people will do anything these days to make a fast buck, DTA, Dont Trust Anybody, thtas my motto and i will ALWAYS follow it idc who you are

 

could you do a speed density tune on these cars? thats what a lot of local LSx guys have done with good results, plenty of rediculously high horsepower hondas using the same method... to me it would make more sense considering we have a wideband for it to target with... then we wouldnt have to worry about all this silly crap, i know thats how the SRT4's are and my buddy just runs open turbo on his... effin' thing goes 8.3@87mph on 18" street tires with the line yanked off the wastegate, a bigger intercooler and an open 3" downpipe...

 

so today i put the stok air box back. No more wooosh from the bov, and i did not loose any boost but hopefully my sensors are back to normal. I did disconnect the battery so everything shoulda reset, got on it a lil bit today on the highway could not really fell a hp difference. Ill find out sat when i go to the track time difference if any

 

It would be difficult to SD tune an LNF because the VVT means lots of VE tables needed to tune it for different cam angles. There are 4 main spark tables in the ECM along with a optimum spark table because of the VVT (there are other spark tables as well.) A SD tune could be done but it would not be easy on this car.

 

as youre about to shift youre always gonna lose boost, its how they run

 

theres not to many lsj's that run strait VE tunes. either all MAF. or blended in lower rpms.

to me its just as easy to get the maf strait and leave VE off. i guess it depends on your methods.

 

so in a sence my car is working, running better with the stock air box cause the ecu is not working as hard to cange sensors?

 

Alright people. You need to listen to what people are actually saying from both sides of story.

This is not as simple as a YES or No question.

***This applies to almost any car on the road***

If your running the stock tune with limited mods and add an intake to your car it will most likely not blow up. This is how most aftermarket companies test their products. They know that stock tunes are very conservative and how their product will change the way the car operates. They make sure their setup is safe.

If your running the stock tune with extensive mods and add an intake to your car you are increasing the changes of it running into problems. Every modification changes a little bit about how the car operates.

If your running a custom tune with extensive mods and add an intake to your car you are in high danger of running into problems. Custom tunes are designed to maximize the performance of the mods on the car at the time. They could be made "general" enough to make them safe on different intake but if that is the case then you DO NOT HAVE A CUSTOM TUNE!

Any time the maf moves from its original location or moves to a smaller/bigger tube it is going to have a direct effect on how the tune operates.

Please be careful people.

 

So you're saying a custom tune and intake is bad with a lot of mods? I thought custom tunes were supposed to help that?

Now I'm more confused.

 

No.

I am saying if you had a lot of mods and then got custom tuned with a stock intake. THEN if you add an intake without getting retuned you can get yourself into trouble.

So my post had the starting setup in Bold and what could happen if you added an intake to that setup without tuning.

Does that make more sense?

 

Ah gotcha.

 

HPT is supposed to be releasing a SD OS upgrade for the LNF.

 

I hope they get all the tables necessary. There are going to be a ton more than a normal LSX ECM has.

 

So basically i just listened to the people who said i would be faster with the stock intake on....well i just took off my fujita and didnt notice a damn thing other than i cant hear my s/c whine.....now i gotta ef around putting the stupid fujita back in...

 

... you know this is in the LNF section. This topic hasnt been brought up in forever. You actually had to hunt for this.

 

I dont think the lsj is AS picky as the lnf is....

 

i didnt really pay attention, i saw this thread a few weeks ago and the guy that said it would be faster with the stock air box kinda stuck in my head. figured i'd give it a whirl.

 

I dont think it holds for LSJ cars. The LNF is a very very picky car when it comes to the MAF and the factory airbox seems to be the best situation for most looking to make decent hp numbers. I dont believe its true but Im willing to learn the hard way :p

 

ya the DI engine with this newer ECU that tries to read the future makes it very tricky. Speaking of which I ordered a used hpt last tuesday should be here soon

 

ya after reading all of the problems that has gone on. i'm not getting a tune until i have all my bolt ons installed and then install the tune then datalog like a motha fu**A

 

Fail for bringing topic to life

 

so how bad does it eff stuff up to use the stock airbox with the AEM elbow monstrosity? isnt that the real restriction?
