Fuel system component list am i missing anything ? - Honda Prelude Forum

Prelude Racer · 02-17-2003, 01:06 AM

alright everyone i got some cash and going to finish up getting mods to support my jrsc... i already have a safeguard with dual monitor so thats going to take care of pinging.

also getting es motor mount inserts to keep the engine from rocking back and hitting my abs lines.

but now i need to take care of my fuel needs... i am running lean here is my list

550cc (peak and hold)
resistor box
AEM fuel rail ( so i can plug my electric FPG sender into it)
steel braided fuel line (TPC write up)
AEM high flow fuel filter... (might as well get this one)

is that it am i missing anything... at this point i am just going to order under the hood stuff... not inludeing a ecu such as hondata or efi... right now i just want to get this stuff installed . cuz i have to install engine mounts and since the jrsc is coming off i might as well do anything else that needs to get done and not have to take out the sc again later.. where is a good place to get all this stuff as well. thanks everyone

umm if you don't get a ecu now, how do you plan to control the injectors? Running them off the stock ecu will only flood the engine with fuel. I highly doubt you will be able to even idle with 550's. I also don't think 550's are needed in a JRSC setup, not even with a 9psi pulley.

as ntprelude said, you won't be able to run the car with 550s and no computer.

my advice? ditch everything on that list except for the 550s and resistor box. there are lots of ways to plumb a FP sender, and besides, fuel pressure won't be that important once you get rid of the rising rate FMU. get the hondata/aem/whatever and the 550s, don't get any of the rest of that stuff, remove the jackson racing FMU, fuel pump, and EMS. get it tuned and you are set.

several have run this setup, and it's a good one. just keep in mind that you can't mix parts designed for one setup (i.e. big injectors + standalone) with another (small injectors + fmu)... fmu + big injectors and no standalone = car will barely run.

remove teh jr fuel pump ? and put in the stock one ? where is a place that can tune my car if i get a efi pms... i know there is none in reno but what about the bay area ?

hey thanks for your advice... but i think i will still get the fuel rail... ... because it seems the easiest way to hook up the sender. I am worried about tapping it somewhere into the fuel line and getting some leak somewhere. as for the steel braided fuel line might as well do it since i am going to be messing with my fuel system. and the fuel filter.... i need to replace it anyway so i was thinking of just getting the AEM one... u address another questions i had... so lets say i removed the JR EMS and FMU and got

550cc injectors
resister box
fuel rail
Steel braided line
FPG instaled
fuel filter
EFI pms

all installed in my car and am ready to turn the car on fo the first time... what should i do.... not turn it on and just take it somewhere to get it tuned first ? or try to turn on the car ... this is what gets me confused after everythin is installed can i turn on my car to test everything ?

schwett · 02-17-2003, 02:09 AM

if you got the pms, you could always get a copy of sharkcohen's 550cc jrsc tune and use it as a starting point. even without that, you could simply set the PMS to -45% fuel and it would just start up and run pretty well out of boost. you wouldn't want to boost until you input some values in the boost table and boost timing tables, but off boost the car would drive almost like stock if you had the right correction factor in there. if you knew your fuel pressure, it would be a piece of cake to get it right.

if you just put the 550s in... and didn't make any changes to your ecu or whatever fuel control device you had, and you started it, it might run very briefly and then die from being too rich. if you did that enough, you would foul the o2 sensors and the cat. i seriously doubt it would be driveable even for a short distance with 550s. we're talking close to TWICE as much fuel as necessary!

whatever standalone you get, it will usually have some provision for a "base tune" which you get from the manufacturer or your reseller or a friend, so the car starts and can be driven to the tuner, or tuned yourself if you have a wideband and the time/knowledge.

cooe cooe thanks schwett .... well shark would you mind hooking me up with ur settings ? and where do i get this EFI PMS i dont mind buying it new... and is there different models of the pms or just one ? i wanna make sure i get the same one shark has .. any other accessories i should get when i order my pms ? thanks alot everyone

Prelude Racer · 02-17-2003, 02:23 AM

so remove the JR ems and the fmu ... but remove teh fuel pump too ? and what do i put in its place

sharkcohen · 02-17-2003, 04:33 PM

Setting up the PMS is easy, if you end up getting one I can coach you through everything you will need to do. You should consider getting an OBDII datalogger along with it, I find mine to be vital for the part throttle, off boost tuning.

Replace it with the stock fuel pump.

DirtyLude · 02-18-2003, 08:20 AM

Like Schwett said, just get the 550's and the resistor box. Make everything else stock. Then put in your engine management. You don't need an adjustable fpr, or anything else other than the injectors. The more you put in, the more that can go wrong.

There's an error in my TPC write up as far as the AEM rail goes. Apparently a -6AN or -8AN fitting is needed to connect right to the rail, not an NPT fitting. I would make sure before you buy parts.

Prelude Racer · 02-18-2003, 02:44 PM

okay so this is my plan ....

order
550cc Peak and Hold Injectors
Resister Box
AEM Fuel Rail (so i could plug my fuel pressure gauge into it)
keep stock fuel line
replace fuel filter with stock fuel filter (cuz the one i have is old)
EMS PMS with OBDII data logger

remove

JR EMS
JR FPR
JR fuel pump ( put stock back in)

install all the stuff then get in contact with shark haha cooe shark ?

is this okay i want to make sure this is all okay before i order anything

sharkcohen · 02-18-2003, 02:51 PM

Yah dude, PM me when you need help, I'm on the board every day.

For an additional cost, you could get the EFI 2 ohm injector driver instead of using a resistor box. It plugs in along with the PMS and eliminates the need for the resistor box. The advantage is that it is plug and play. The disadvantage is that it is expensive. When I bought my used unit, it was part of the package.

Prelude Racer · 02-18-2003, 06:36 PM

okay cooe shark appreciate it.

one more question when i go to order my EFI PMS is there only one kind ? I want to make sure i get the right one. I know there is different ones... like one for mitsu and another for honda but as long as i get the honda one will it be the same as yours shark ?

also how do i tune it.... with a laptop ? or should i get the PMS terminal... i already have a laptop so i could use this right ? i would just need to get the interacq data collecton software

where do i get the obdII data logger ? thanks

sharkcohen · 02-18-2003, 06:48 PM

If you are buying your PMS brand new, from what I have heard the latest version is better than mine. Give EFI a call and ask Doug about it. It has a higher resolution of tuning available right on the handheld unit. Save yourself some money and skip the software. With my outdated version of the PMS I am only using the handheld unit and am getting great results. I wish I had the latest version

When you order it, make sure you are getting the Honda unit with an OBDII harness.

The OBDII datalogger setup I use is from www.pocketlogger.com It runs on Palm OS.
