ARC2 Help! - 3000GT/Stealth International Message Center

VR4Joe · 08-06-2009, 07:13 PM

I know you guys are the best at the arc2, esp Matt.

I need alittle help, i just hooked my arc2 up to my car and can only get it to idle, everytime i give it gas, and then let go of it, it stalls out

My mods are...
15g
550's
Hot wire denso Pump
FPR at 35 with vac line
HKS SMIC

I just need a good base, i tried the numbers on stealth316 and i can't idle correctly.

Right now i have

Low +6 clicks
Mid -7
High -2
Accel +2

Where do i go from here? I idle at about 14-15afr and at about 600rpms which seems pretty low.

Any time i get into gear, give it gas i move alittle, once i let go of the gas, i lean out and stall.

Well to start with do you have a ARC-2 GP R5? (look on the back of the unit)

VR4Joe · 08-06-2009, 08:27 PM

Yes i do. I was just driving in my driveway, going forward and backwards, if i go any higher than 2k rpms the car stalls. The car is running really rich and if i try to lean it it stalls as well. I can't even adjust the mid, she stalls if i lean or richen.

Did you get it from us? if not was it a NEW unit or somthing you baught used.

Your best bet will to be FIRST make sure EVERYTHING is wired in and hooked up correctly.

Then call me from a cel phone wile inside the car.

VR4Joe · 08-06-2009, 10:13 PM

I also have an SAFC hooked up as well, i wired both of them just like the stealth316 diagram showed.

It seems like 1600-17000rpms while driving the car just boggs and stalls. I haven't even been able to get out of 1st gear

VR4Joe · 08-06-2009, 10:14 PM

When is the best time to call you up, i know you're a pretty busy guy.

I would remove the AFC no need for that to be there.

VR4Joe · 08-07-2009, 06:55 PM

I tried calling you today, but i don't believe you work on fridays. I uninstalled the AFC and it's still doing the same thing, i got it to idle fine, but when i put into 1st and start to drive slowly, it's fine. Once i reach about 1600 rpms she goes crazy, bogs, and then stalls out. During this my AEM Wideband is also going crazy reading really really rich and then leans out untill the unit gives me the three dashes.

I then did a vac test and found no leaks, she holds air like a champ. What could be the problem??

Again my current settings are

Low+7 clicks
Mid -7
High -2
Accel +2

What MAS are you running? 83mm? 92mm?

If you are running the black 92mm your high is WAY off for 550's it's going to be more like +8ish

VR4Joe · 08-08-2009, 01:06 AM

I have the Ford 83mm MAS

It's got a 4" diameter because i just got a filter for it.

Can you see if i have the correct pin numbers for all the connections. Grey Haze gave me these numbers for the hybrid ECU just to make sure i installed this correctly

AirTemp Pin#72
Baro Pin #95
IPS Pin #87
Air Flow Pin #90

For the ARC2 ground, do i hook it up to the ECU ground Pin 26 or the sensor ground PIn 92???
