Dsx Aux Fuel Pump kit VS AGP dual kit

[eLeSthree]

Im about to upgrade my fuel setup to run E85, and increase the boost. I have a zl1 pump, a self modified FPCM (holds 58psi at all times), DW90# injectors, and a BAP. Data logging shows my demanded and actual FP is always good, so at my current power this setup seems to be perfect. However the switch to E85 will require more flow.

Im torn between the less expensive DSX Aux pump kit, and the dual agp kit.
Which would you buy? They’ll both get the job done...

Couple questions, does the DSX convert the system to return style?

Is there a major tuning change needed once you ditch the fpcm and go return style?

And lastly, I have E85 all over the place here and i dont daily drive
My camaro. I wasnt even gonna bother with the flex fuel sensor and just have two tunes. One for 93 and one for E85. Bad idea?

It could but you would have to run a return line but there is no reason to try to convert it to a return if it does what you need it to do being returnless. It doesn't make sense to make it return style, to me anyway.

You can remove the FPCM and then tune out any codes. There are some other things you need to do in the tune but I am not too savvy on that part.

There is no reason to switch back and forth between tunes. The sensor adjusts on the fly once the E85 part of the tune is done. The sensor does the same thing switching the tunes back and forth would do.

Answers in red.

The DSX will be an easier install. With the AGP, you need to drop the gas tank or cut an access hole under the rear seat. I had a Squash setup and the first time I dropped the tank. When I changed over to E85 pumps, I cut the access hole. Much much faster. There was no extra dirt or noise afterwards. There are a few threads on here about the access hole.

If you are planning on going for a lot more HP in the future, do the AGP system, if you will be content staying within the confines of the DSX system do it because it is cheaper and easier to install. I must warn you - most of us are never content and want more once you get used to the power.

Blake pretty much hit the nail on the head. I was in your same boat earlier this year and thought about the DSX kit. It is claimed to be good to 1000 rwhp on e85, but I think that may be a bit generous. If it can reach 1000 rwhp on e85 I think you may need a BAP.

The AGP setup is a sure end to your fuel woes. A double pump system should cover your setup and then some unless you go absolutely big.

I ended up going with the triple pump setup and ID1700X injectors, because I never wanted to look back at my fuel system again unless its maintenance. I did the hatch instead of dropping the tank. Accessing the pumps are simple matter of minutes now.

I already cut the access hole when I did the ZL1 pump. Just ordered the access panel trap door for it actually.

I was thinking about skipping the flex fuel sensor and just always running e85. Its just a toy car, and I have E85 on every corner around here.

I heard running the agp feed hose is a bitch.

I read that too, but it wasn't hard for me at all. If you insist on not running a flex fuel sensor, I guess it would be fine. But why not? Not that expensive nor much more work for the tuner.

Yea, all it takes is one bad tank of gas... ok, scratch that. Bad idea.

Running the feed hose takes two people maybe 3 minutes. Now doing it by yourself would drive you crazy. Or you could just run it up along the outside of the frame if you want. It's your car.

I have two people and three minutes, but I don't have $1700. LOL!

Looking like the best option out there though. You'll get my money soon enough...

Flex sensor all the way, and you are looking at 700 dollars difference between the 2, so I would say save up if you have to and go with the agp system, then you have a complete system rather than using crutches to make it handle your needs

I would be interested in buying your zl1 pump if you replace it

I have a question about your flex fuel sensor option. I dont see it listed on the website by itself, so its hard to find more details online. When you add the sensor to the dual/triple fuel pump system, does it come with a plug and play harness like the dsx kit? I know i still need to run one wire to the main pcm harness with their kit.

How does yours work? is it just a sensor without a wiring harness?

Comes with everything you need, ECU pin, FF connector, wire, etc. It's an already wired pigtail for the flex sensor and then you have have to pin the ECU connector, run the wires and connect them to the pigtail.
