The fuel supply system works just like the one on our stock car.

Basically, all you need is this:

Fuel rail to distribute fuel to all the injectors (not sure if its included)
Fuel supply line (from fuel pump to fuel rail)
Fuel return line (from the FPR to return to the tank)

Depending on where you choose to put your FPR, you may need a line from the fuel rail to the FPR.

It's not overly complicated. The hard part is figuring out how you want to do it since it could be done in many ways.


All I did was actually use the stock banjo fitting for the fuel supply line. I cut the return line and used a barb fitting on the FPR. Then I bought some more barb fittings and hooked it up from the fuel rail to the FPR.

 

for those running ITB's, are you all running test pipes? is it pertinent to do so or will high flow cats really restrict ITB setups?

 

ITB with standalone EMS will eliminate emission components.... so theres no point of running cats anymore


but yeah, it is recommended... if you open up intake, you should free up the exhasut too, to get the peak out of the setup.

 

Yeah, I understand the removal of emission components, but wanted to keep the high flow cat for a few reasons. My catback isn't entirely all too free-flowing either, but imo, all balanced to each other where they're not bottle-necking each other.

I do love the response of my setup now, but hearing the excellent response of ITB's has always had this nagging at me.

Current setup for reference:
j's intake
berk header
berk high flow cat
amuse dual r1
aem ems tuned by church

thanks for the insight!

 

The cat still catalyzes exhaust gases even without the other emission systems.

 

The Berk high flow cat flows nearly 90% as well as a test pipe and more than twice as well as the stock cat. You won't lose but 1 or 2 hp max by running it versus a TP.

 

But how do you know how well the Berk cat actually works as a catalyst?

Even though you have a high flow "cat", it doesn't mean that you're being just as friendly to the environment as the stock cat.

 

I just re-found one of the video's of my 1st ITB dyno by 2nrwerks done at Race Related in St. Pete. and finally uploaded it to youtube
Enjoy

Would TPS tuning instead of MAP tuning work if you take VTEC into account by having the EMS assume a certain percentage of higher fuel above the VTEC point?

Anyone tuned by TPS here?

 

mines13 used alpha-n and switched to map .... another thing to take into account is weather change in the bay area, alpha-n is not good for a big weather change.
