My Port Injection - Mazda 6 Forums : Mazda 6 Forum / Mazda Atenza Forum

cageyvet · 02-17-2013, 03:59 PM

My port injection setup has been done for a while but in between making another header and changing some things ie, exhaust, intercooler piping I finally got around to doing a little tuning this weekend and all I can say is its good to have plenty of fuel.

Here' my setup

Double Pumper DW65c intank pumps
4x FIC 1100cc/min High Impedence Injectors
1x AEM Universal Adjustable Fuel Pressure Regulator
1x Custom Fuel Rail
1x Stock Manifold Pnp/ Modified for PI
Replaced all the fuel lines with bio-fuel compatbile fuel line
1x Fuel pump hardwire kit/relay (for second fuel pump)
1x Split Second Additional Injector Controller (will be upgrading to Pro-Efi eventually)

Right now I'm running the car on 50/50 e85/gas since my fuel pump internals did not like 100% e85. I still have my meth kit hooked up on the car since I didn't feel like buying a larger intercooler but its only running a D03 nozzle to cool the intake charge. The hta82 is a nasty turbo when its not starving for fuel. I took it out for a spin Saturday morning after some Friday tuning and it annhilated my tranny mount (street unit) which in turn took out my axle, lol. Its all good, I ordered a replacment mount/axle and I'm going to make another mount next weekend. Car puts a big a$$ grin on my face now.

Nice! Did you replace the ECU with a standalone? How are you tuning? Post up logs and VD graphs if possible....

Unfortunately, I'm still running the stock ECU/cobb AP, in conjuction with the split second injector controller. I will be switching over to Pro-efi when it has control over the High Pressure side of our fuel system which will be very soon. I don't have any logs saved from last Friday b/c I was logging with my laptop instead of the AP but I'll post some next weekend after I get the new axle/mounts in. I was hitting 4.30 maf volts on a 3.5" maf housing on only 18lbs. Afr's were in the 11's, low 12's up top and I was able to run as much VVT as I wanted

. There's a ALOT of headroom in the PI system b/c right now I have my max duty cycle % set @ 25% @ 5.0 maf volts, but with the increased based fuel pressure I run and the 4cylinder 4 stroke,settings I have on the split second I get more fuel than than the 2/4 cylinder 2 stroke setup the 5th port guys use.

so what kind of dual pump setup you have returnless?

cageyvet · 02-19-2013, 11:55 PM

I never said it was returnless, its just not in plainsight except if you noticed the return line coming off the bottom port of the fpr.

It's hard to see the picture need more close up pics.
Also what kind of dual pump setup you have and how you got the other put to turn on and what size fuel hose.

1. Im running two of the deatschwerks DW65c fuel pumps. I would have preferred to have just run a bosch044 inline or two aeromotive stealth 340 lph intank pumps but I was already running a single DW65c and my buddy sold me his DW65c super cheap, so that's what I used.
2. I replaced all the fuel line with gates barricade fuel line 3/8" rated at 225psi/bio fuel
3. Used a hardwire kit to kick on one pump and a relay for the other.

The only thing I really don't like with this setup is that the my fuel pump internals can't handle the 100% e85 and unless there's a coating thats available that can prevent them from sticking. I'd rather run the port injection off a fuel cell without touching/tapping into the stock fuel system. However, with just the initial results on 50/50 e85 I'd venture to say ill be able to find MBT with just 50/50 e85 but its a pain in the ass going to the gas station and filling up at two separate pumps.

Here's a pic of the rail, its tucked away from plain sight.

how are you mounting the pumps in the tank?

The pumps didn't need anything special for mounting purposes in the tank since the stock basket holds them in place pretty snug.
