PTP-FTM v1.0 Tunning "HELP" thread. - Page 45 - SRT Forums

Okay just called Aaron and he basically told me how to use my Multimeter...I'll be testing my connection tommorrow and see what I get...Hopefully I get thei fixed and ready for dynoe soon....

Car symtoms:
Hickups at idle, makes A/F's dip into 12 at idle when it does this

Connection Message Box when connected to FTM:
srt-4 type and Map 2

Actions Completed:
Replaced Upstream o2 Sensor, this HIGH fixed LTFT
Placed WB in correct Bung
Resetted Computer
Tested Wires on FTM

John Volts suggestion for the following wires

Red Wire = 12v
My Reading = 12.39v

Grey Wire = .79
My Reading = .73

Yellow Wire = 2.2X
My Reading = 4.10

White Wire = 2.2X
My Reading = 2.17

Purple Wire = 5.0
My Reading = 5.0

I didnt check ground, didnt know how to....

Bump for an answer today please!!

Problem is the yellow wire, you are adding a ton of fuel and causing the map to read way to high and its adding a ton of fuel. At idle your car thinks its running in boost. The yellow wire needs to read at the same or lower then the white wire. What are your FTM settings again?

What GB did you get your FTM on? I have sent you another FTM correct? If so then it has to be your settings. Call me tomorrow with car and laptop in hand so we can go over this together. I want your muilti meter there as well so we can measure the voltage on that yellow wire when we make adjustments to the FTM fuel maps.

My global was zerod out and my clamp was at 4.85! So that's why I was like why's me yellow wire reading so hi! Ill call you tommorrow!

I didn't get my FTM thru a GB. Think it was an extra one you had or something!

04SRTMAN · 11-10-2006, 10:09 PM

hey I had a quick quuestion. What kind of a difference did your FTM make? Thanx.

BlatallicSRT · 11-10-2006, 10:29 PM

It let me tune my fuel out! Tuning equals power!
But at the moment it idles rough as hell so I'm trying to get that fixed!

If you pull fuel does the voltage change on that wire? Try this before you call me. It very well could be that you are set up on the wrong map signal for the input to the FTM (2.25 bar vs the 3 bar set up) that would explain the difference in voltage. I dont know why you keep having these issues, dam it.

ptperformance · 11-11-2006, 01:12 AM

Also I want you to turn autotune off and then tell me what the voltage on that wire is. I have an idea but I need to see if it might be the cause.

John Volts suggestion for the following wires

Just Harness without the FTM plugged in
Red Wire = 12v
My Reading = 12.39v

Grey Wire = .79
My Reading = .73

Yellow Wire = 2.2X
My Reading = 4.10

White Wire = 2.2X
My Reading = 2.17

Purple Wire = 5.0
My Reading = 5.0

Plugged to the FTM and it being Zero'd out and 5.0 clamp (autotune off on all these tests)

Red wire = 12.28

Grey = .73

Yellow = 2.18

White = 2.18

Purple = 5.0

Plugged to FTM and taking 6% away with a 4.85 clamp (Autotune off)

Red = 12.26

Grey = .73

Yellow = 2.05

White = 2.18

Purple = 5.0

Adding 6% fuel with a 4.85 clamp (autotune off)Red = 12.25

Grey = .73

Yellow = 2.32

White = 2.18

Purple = 5.0

I didnt check ground, didnt know how to...

Diller anything on this after we talked?

BlatallicSRT · 11-18-2006, 09:09 AM

Car is running good.....upgraded the WGA spring you sent me and wow, car holds a lot more boost to redline.....Got to get my new boost gauge installed and I'll be able to start pulling fuel out.....with it in the 10's the car pulls strong, I can only imagine when it gets tuned and the W/I turned on...

Awesome, glad you finally go it working right, Diller.

nightmare_rebuilt · 11-18-2006, 06:33 PM

so i did a fe runs tonight with a budy's scan gauge, intake temps at normal driving were 64f, cant recall at wot.

LTFT: 13-17
Timing add: 29 at redline
retard:6 @ redline (2* as soon as i go wot)
afr: 11.8-12.2

after i played with the w/i : start @ 4psi, full @ 8psi

timing add: 32 @ redline
retard: 4 @ redline

-should i richen it up a little to get rid of that knock?

my mods are pretty much all bolt ons, except ported manifolds, still stock internals, and w/i (50/50), stg 2 inj, spike 23psi hold 15 to redline.

any advice?

cold nigths rigth now here in FL

Try an 80/20 mix on the WI and go from there. Sounds like your car is running like a beast.
