My R is running too rich i can smell it when its idling, now its supercharged, what do i need to make it run better? fuel pressure regulator.

 

if every thing is stock. It will be rich to make up for the extra Air your putting to it at high RPM so it dose not starve.

i would go with some sort of AFC

fpr is not the answer and don't get an afc, i had one it was a waste of money imo. get some proper ecu tuning done with a wideband.

what other work was done when the charger was installed? were larger injectors installed as well? i find it strange that you are running rich since having started adding more air into your combustion chamber. usually that results in a lean condition.

 

FPR + ECU Tuning..

 

The JRSC comes with a bigger pump, FMU (adjustable) and possibly a "fuel enrichment circuit" (similar to the ones sold on ebay).

There's not much you can do with the off-the-shelf setup, but if you ditch most of the JR stuff, go to some bigger injectors and get a good tuner to do some work, you'll be much better off.

 

yeah, doesn't make much sense to buy a kit that uses second rate options for fuel management.... that is why i went turbo and put it together myself.

 

I just slapped on the charger, I didnt do anything else. Now if I were to tune I would need a computer, or can I just chip it. I regret getting rid of my AEM stand alone system.

 

Dyno tune and street tune It will idle like stock.

Thats what I had done to my car. If you got the cash do it.

How much was the dyno/street tune? Now to tune it what do I need. I am going to need a computer or can someone that knows what they are doing just use my stock ecu?

 

Well my car is turbocharged.
I went to NHR (Neetronics). I'm using a chipped P28 ECU. It was on the dyno for 5 hrs and street tuned for 30 mins.
My gas mileage didn't decrease that much and the car is very reliable.
They charged me $160/hour for the dyno, and the street tune was free.

So if you got the cash, do it. Never cheap out on tuning.

Truth!

 

imo you should street tune first to get a good base map and figure out all the bugs before you spend that much on the dyno. it will also bring the dyno time you need down dramatically. i'd say 3-4 hours on the street and 2 hours on the dyno max.

 

Hey, I do not know alot about tuning. I left that to the pro tuner's........and to me, Paul @ Neetronics is a trusted and well known tuner. And I think he knows what he's doing.

Sidenote: I had a Chrome basemap(ran like crap) on my car, Paul just ripped it out and put a new chip in and started from scratch.

My car runs great, I have no complaints.

Paul knows what he is doing, but he always tunes conservatively. So he's a great guy to go to, to ensure you have a reliable whip. Just remember, the numbers you put down on his dyno (a Mustang dyno) will be much lower than those on a DynoJet dyno, the typical standard.

Do don't be freaked out by only having in my case, 137hp at the wheels on my ITR NA, when I had it. It acutally put down on a dynoJet 177

 

Are you serious about the dyno? Nice!
I put down 180whp on his dyno. I wonder what the DynoJet dyno would spit out...haha

DAN

 

^^^ what kind of setup and psi are you running when he tuned it ?

 

I have a boosted gsr...she's running great. fire me a Pm, we'll talk...

don't apex and don't use a rising rate fpr.. OLD SCHOOL
