If ZZP is only 4 hours from you just go there.

 

Ya if you're willing to drive there and get dyno tuned thatll be great tune for your car. I would just watch maf trims on an intake thats custom and noone else has ever used

 

I don't know what maf trims are :x

 

I would assume trifecta tuned for this. It doesnt sound like he has an intercepter so he might want to add that and a dual or triple pod to the list for his zzp trip.

 

The LNF operates in a closed loop system for most driving (it monitors the combustion and adjusts fueling to keep the correct combustion ratio). The trims he's refering to are the long term fuel trims (LTFT) which is how much extra fuel from the tune the ecu is adding to try to keep the correction combustion ratio. Its extremely complicated yet simple, basically you want your LTFT to be + or - 3 anything away from that additional adjustments to your tune should be made.

I would try to get in touch with Trifecta if you still have the cable and get your stock tune file so when you go to zzp or who ever you can flash the stock tune back so they can tune your car.

 

OK the maf sensor tells the ECU how much air is coming into the engine so that it can calculate the proper amount of fuel to inject. So it is very important to get that set up right which ZZP will do for you

 

Yeah I have the red trifecta cable that plugs into a USB port. May I ask what a interceptor and dual/triple pod is? How much is a dyno tune from zzp? And the additional cost of these other things you mentioned? Thanks for all the help. I truly appreciate it.

 

What year is your car?

 

Wow first custom pipe setup ive seen a dd cobalt as picky as that maf is I wonder how its liking that custom intake

Op you should definitely take your car to zzp and get it dyno tuned it will cost you a few hundred to see a night and day difference they will also be able to diagnose common issues guide you along the way and show you some of their nice shiny parts

 

Just what I was saying a good shop like ZZP will know how to get that running well

 

So are you guys saying that I ran into a car with a really nice setup? lol. It's a 2008

 

It's a unique setup for sure. Hopefully the maf trims work out and you dont have to change anything. So you just have a boost gauge on the a pillar to your left? The other guy was telling you to buy gauges but you dont really have to so you can tune an LNF

 

Awesome. Well I hope that it all works out with it having custom pipes/intake and all. Unfortunately, I'll probably have to wait a few months before I can get it tuned.... I would have plenty of cash but the god damn bank would only let me take out a 3 year loan on the car because it was older than 2009...This thing is in better condition than most 2009+ vehicles I've seen >.>...It's so sexy!

 

Never said it was a requirement, but having interceptors on an lnf gives you a lot of information about the engines current operation and that all important knock, without having to be connected to hptuners

 

I just really want to make sure that I have a quality setup. I have learned that when it comes to price, I'd rather pay more for better quality. Do it right the first time, you know? If zzp is the way to go, then that's what I'm going to do. This is my pride car right now and will be for a long time!

 

That's why I asked what year he had a RPD shows most of the stuff you need to know

 

I always forget about the RPD I guess not having one makes it easy to forget

 

RPD is nice and all, but it is limited in what it shows compared to an interceptor.

 

Other than EGTs i think the rpd does it all

 

Ignition advance, oil temp (calcd), maf lb/min, knock, shift light?

 

Quality looks good main thing is that it doesnt leak bov are known for leaking and there are a lot of welds in that setup zzp can def take care of a boost leak test

I really dont want to blow your mind with too much info but you might want to research getting rid of that bov setup there's a lot of different opinions on this subject and there has been many threads on here about it so take a look but basically the car was not designed for it. I wholeheartedly disagree with this statement that it was a preventative maintenance measure. the stock by pass valve system works just fine and is a lot less complicated than a bov setup. Bov adds no performance to the car it only makes noise and requires a tune for the car to run right and adds another couple places that can leak. People have and currently run bov setups without too much trouble but most dont because on the stock turbo its just not necessary.

 

Yes, no, no, yes, yes

 

His BOV is a recirculating setup see where it comes back into the intake behind the maf. It's basically a different way of doing the same thing the stock does

 

Good to know it has most of the important stuff.

Agreed, the recirculating bov is no different than the stock bpv(sometimes better as long as the previous owner didn't buy a cheap one). If you got to zzp they'll know how to adjust it if needed and can test for a boost leak.

 

It is a recirculation setup but its stil gotta be about 10x more likely to have a boost leak than just running a bpv
