Is anybody running this regulator and using the boost referencing feature?

I'm thinking about incorporating this into the fuel system and am just wondering if it works like its supposed to(1:1 rising rate). I've heard some don't work right.

Here's a picture of it.



Thanks

Johnnie

 

I got one not like that but its raises 2to1 with boost. I couldnt tell you what the part number is cause I got it used.I bought it form Reckless. ITs a nice unit and the adjust FP is good to have <img src="gr_stretch.gif" border="0">

 

I have the boost referenced regulator and it works great. No probs at all.

 

is it manifold referenced or just boost referenced? I have one made by Holley that is vacuum/boost referenced and would like one that Only responds to boost

 

Hey thanks for the replies.

Here is what I'm thinking. Hang this regulator off the end of the stock fuel rail. Then hook it to the return line that is on the FMU and take the FMU off. Run a boost line to it and put my fp guage sender in the 1/8"npt port. I'm also going to get rid of the pulse damper on the crossover and put in a piece of braided line with the appropriate fittings.(in place of the whole crossover)

This should give me adjustability and unrestricted fuel flow. <img src="gr_grin.gif" border="0">

Maybe even paint the fuel rails silver while I'm at it. <img src="gr_stretch.gif" border="0">

cablebandit - I think it is just boost referenced but I'm not sure.

Here's a question. Can anybody explain the difference between and boost referenced FP regulator and a FMU?

Both's funtion in life seems to be to raise FP under boost.

I think this would be usefull to understand.

Thanks.

I'm thinking about trying it.

Hey Heath

I think the FMU is used when the injectors are too small for the application. It raises the fuel pressure at a much higher ratio than 1:1 in order to keep up with fuel demand. The one in the ATI kit is probably around 7:1. <img src="gr_eek2.gif" border="0">

The boost referenced FP reg.just keeps the fuel pressure from dropping as boost comes in. When boost comes in you basically loose the the poundage rating of your injectors because they are working against the boost pressure. When you have big enough injectors the computer can handle the fuel enrichment but it doesn't know that the fp is dropping and doesn't compensate for the drop. This is where the regulator comes in.

Does that make any sense? I just started typing before I thought so things came out all over the place. <img src="gr_eek2.gif" border="0">

Take it easy.

Makes sense.
The ATI FMU is adjustable though right? Can you turn it low enough to get closer to the 1:1 ????

Hey Mike

I'm thinking it would be even better with your current setup.(high boost) Do your O2's start to lean out up top?(not necessarily go lean, just start to drop)

I'm just thinking it would be easier to get a steady A/F ratio across the board with it.

I think I'm going to get it. <img src="gr_stretch.gif" border="0">

"Soapy" Hahaha. LOL <img src="gr_images/icons/wink.gif" border="0"> <img src="gr_grin.gif" border="0">

Hmmm....It is adjustable but, I don't know how much you can turn it down.

Sounds like Jason(Jay@GWP) needs to answer this one.

Yeah, it does.
It's really rich (below 10:1) until it comes above 10:1 at 5500 and ends up at ~ 11.8:1 at 6500 RPMs. But I think I can have Superchips fix that.

Here's the dyno:

Also, I think it may not run quite that rich actually driving. But the O2s are high.

Also, it's gets noticeably higher now on the passenger-side now that my fuel requirements have increased... that dang restrictor between the fuel rails, I guess.

 

The regulator shown, I believe part #13109, does function MUCH better than the small aeromotive one (LT1 style) as our kit was released with. We have run ALOT of tests using multiple regulators plumbed in pretty much every location in the fuel system including making a custom plug to replace the noise suppressor with. The absolute best response we had was with the Weldon regulator but this Aeromotive piece was steady right behind it compared to a few others. We actually have custom fittings, somewhere, for these aeromotive regulators to use the quick connect GM fittings on the stock return line. Our car works very well on the boost reference at a glance but my eyes pretty much stay on the road. It is hooked up as a boost only reference but can be hooked up to vacuum/boost (manifold) if needed.
Hope this helps!

Hi Tom

The #13109 is the one I'm looking at. Thanks for your evaluation.

I've got a question though. Where do you hook it up to a boost only reference? Do you hook it up to a regular vacuum/boost line and put a one way check valve inline so it only reads boost?

I'm going to hook it up to the end of the driver side fuel rail. I already have a return line up there that was hooked up to the FMU that came with the ATI kit. Do you see any problem with putting it in that location?

Thanks for your input Tom! And thanks for all your help with my fuel/tuning issues on my Turbotech kit. Tom has been the greatest help a customer could ask for...and I'm not even a customer of Incons. We need more people like Tom in the business! <img src="graemlins/gr_hail.gif" border="0" alt="[hail]" />

Tom is this an item you sell??? or do you have part numbers we can reference and a distributor to buy from? That would be extremely helpfull.

Thanks in advance!

I love those fittings. Push and click. Man thats nice. I would love to know where they sell them at. <img src="graemlins/fluffy.gif" border="0" alt="[Fluffy]" />

 

I talked to Tom about the push-click fittings a while back, I think they are fabricating them at Incon. I am not sure if they are exactly the same but Allan Aircraft, sells adapter fittings that convert AN to whatever they are called. Not sure pricing but fittings from the company are usually $30 bucks a pop. They dont have a webpage. There phone number is 818-765-4992.

They are high quality 304/316 SS fittings, but a a little to expensive for automotive use.

 

Ok, Those Of You Using The Aeromotive 13109 Fuel Regulator With An Ls1, What Pump Are You Using? Im Really Confused And Need Some Clearifying. Im Going To Use The 13109 Reg. Because It Has The Return Fuel Line On It Which Is Nice. But What Pump Do I Use With It. The Aeromotive 1000 Only Has 45 Psi. The Original Pump Had Like 60 Psi. Is That Okay? Thanks A Ton.
