LSA Fuel System

[joeko23]

I'm trying to gather as much info on LSA swaps as I can, and I'm a little confused about the LSA fuel system mainly the pwm, the stock ZL1 and CTSV both use this system, why are people buying the vaporworxs setup? Why aren't people just using stock system? Am I missing something? Does the stock system need to be reprogrammed?

Just seems like people are having problems with the Vapowrorx system and I think ricks and tanks also makes a pwm system for the lsa.



People add pulleys and new injectors and these engines make 100 extra hp all on the stock system, but the aftermarket systems you need to upgrade to 2 ctsv pumps if your running anything other than a stock setup on an LSA.

I have a vaporworks pwm system for sale if your decide to go that route.

I have a Vaporworxs PWM and it works flawlessly.....first I have heard of people having "problems" with the system. Also using the Rick's Vaporworxs tank on my LSA....

It's my understanding that it is problematic to run the stock system, as it needs to interface with the body control module, or something to that effect. I researched it and it turned out to be a PITA, so I called Carl....best thing I could have done in that situation..

The stock ZL1 is a single pump style. If you check out the camaro5 forum and the zl1 sub forum everyone is upgrading the fuel system with a BAP or something at the 650 mark. The CTS-V is a duel pump which uses a Dw300 style pump (2 of them) and can support roughly 750hp (crank). I have not heard of any vaporworx issues and I've been checking out every LSA build i can find. The vaporworks controller basically ties into the stock subharness and adds fuel. Way easier to use than modifying a stock system.

The stock LSA injectors are good for about 10% overdrive pulley with headers depending on the tune. Most upgrade to the FIC, ID, other aftermarket injectors.

My LSA swap will use the CTS-V module, Vaporworks pwm with corner pickups, and the ricks tank.

X2 on talking with Carl he knows this stuff inside and out and is super nice.

Good point Nick...I am using the ZL1 fuel module at Carl's recommendation......works great....

I use the Vaporworks Pressurworx setup and it has worked flawlessly for 2 years now. Please let us know where and what issues you have heard about vaporworx or consider editing your post.

Kidding. But we haven't had any vaporworx issues either. I mean it's a pretty simple setup. Usually it's user error, or another component not functioning properly.

Regarding using a factory fuel pump controller, my assumption would be that it's integrated into the BCM and that's why nobody is doing it on the aftermarket/retrofit side.

I apologize if I threw vaporworx under the bus, but that wasn't my intent, I just wanted to know why people are not using the stock set up and it seems like no one really has a concrete answer, its just assumptions.

As far as finding problems with Vaporworx, I just saw several posts not sure where, but the person was having issues at WOT. Again, it could be completely unrelated to the Vaporworx system but this person was concerned that Vaporworx system could be the culprit.

Just want a reliable fuel delivery system, the stock system is very reliable (I have a ZL1), so why mess with a good thing?

I will definitively reach out to Carl to get some concrete answers.

Thanks Tom.

I just went through your thread on Lat-G and you gave me LSA envy......I need to get mine in!

You need to adjust the fuel demand based on boost. Vaproworks does it be tapping into the manifold from their website:
The pressureworx system uses the engine Manifold Absolute Pressure (MAP) sensor signal to adjust the pressure output of the fuel pump accordingly.

The factory system isn't designed to be a stand alone system. Its designed around a whole car. The reason its not done is its complicated, expensive, and likely very time consuming. Anything can be done but you'll likely won't find much info on using the factory system.

Good luck and keep us posted on what you do.

i have a lsa 68 camaro and use tanks inc with upgraded 400 pump made 600whp no problems 8an feed to holley filter and return regulator with 6an return line, just make sure you run vac to the reglator so the pressure will go up

Sorry to be a bit late to the party.....

A Google search of "vaporworx problems" netted this http://www.lateral-g.net/forums/showthread.php4?t=42171 and the same/copy of thread here https://www.pro-touring.com/threads/...re-at-high-rpm

Starting at the first post, the owner did not have a VaporWorx PWM, just a Gen5 pump in a Rick's tank but a poor power supply system. After swapping to a VaporWorx PWM controller, all was good.

After the above, I could not find any others in the next seven search pages. Please let me know of any others so I can address them properly.

I'll be glad to help with a pump, controller, etc. system to best suit your build as well.

I know this is a old thread but informative for me. I will be having my builder call you. we are just now at the fuel system part and I am going to suggest you guys or at least talk with you. thank you
