Help get Silver running again!!

Teach, isn't yours running to rich right now? Bullet yours might be running a touch to rich when idling? Definitely need a wideband in there.

well ive got no money for that. and prob wont for a while. how do i lean it up a bit? remove the 180*?

What I have found can cause the truck to stumble after reloading the tune is the truck pulls too much fuel and leans it out momentarily. For instance, when I reload my tune after tweaking shift points the truck will pull a lot of fuel, the A/F will jump up to around 16.0 and it will stumble. Now in my case it never stalls and it relearns the cam within a few days. It is tough to tell if this is going on with nick without a wideband to see what is going on with his A/F.

I didn't realize there was no AF gauge in this truck. Guess that wasn't too smart any tuning attempt now will be about as useful as Helen Keller trying to give you help to hook up a trailer.

im not trying to get any custom tuning right now...

Uncalled for. We were all giving suggestions. I'm hoping you were joking but it didn't come across like you were

I read your org response to that anwser and not this one... No one is trying to tell you that this or that is deff the issue but trying to help you trouble shoot everything. If the truck is having running issues the PSC1 and wideband will allow the fuel to be tweaked and you will be done. Everyone on here knows even though both your truck and Teach's are the same the computers might act differently causeing one truck to be fine on stock pcm or SC tune and the other to have issues. All in short were tring to keep you and the motor in one peice... rant over bud, not trying to sound like a grown up because im not, got 3 years on you thats it lol.

 

[Silverbullet08]

i know and understand completely. i guess that comment just pissed me off for some reason. ill see what i can do on getting a wideband...

Alright I've done quite a bit of tuning with the PSC-1, and it's basically only really decent at adding fuel at WOT. The PSC-1 works by manipulating MAP voltage, which also can have adverse effects on your trans, adding fuel isn't a problem, removing fuel can bring trans carnage. If you're able to just remove fuel at idle you'll be fine, any higher and you're asking for trouble. The PSC-1 is a poor replacement for a custom tune. Honestly I would either get a SCT or Diablo and have Hemifever/Sean tune it for you. I know money is tight but later when you can afford it, you'll be much happier with a custom tune. Another thing is you need a laptop to use the PSC-1, not sure if you have one.

ok yea i was reading about the psc 1 lastnight. just judging from that i would rather save money and get a custom tune. only thing is i really dont want to lose my shiftpoints... i know jason is gonna be doing the stack so i might wait and see how that works out for him.

idk if the computer is just taking longer to learn bc we did both cam and headers or what. like i said the past two days sometimes i can come to a stop and it wont die others it will. and yea i do have a laptop to use the psc for

If you can wait till the end of the year I will be able to tell you how the stack works out. Really, you should be able to drive the truck without issue on just the SC tune for as long as you want. I am at five months on that tune with this cam and no issues.

Just jokes man. Just gotta go by feel. Thats how I tuned my mustang until I waited for my Innovate O2 to arrive. Turns out you can get it pretty close without much for monitoring. On a side note my car is blown and has a cam and new heads and it too would fall on its face sometimes when I would come to a stop so I would have to play with the throttle to get it going and stay at an idle at lights. what we did (different on a ford EEC IV system) is calibrate the TPS. The car was not recognizing that the throttle was dropping all the way to idle and the fueling was off. What we also did was add some fuel at idle and now it is much better. This could be some food for thought to give the TPS a reset (using the slow full to the floor depress thingy) and if you can with your psc 1 or what not try playing with adding or subtracting some fuel at idle if you can. Sorry if I came off ultra douche but now looking back at it I could have worded it better.

There have been numerous people stack the SCT/SC without issue. I dont think i'd try doing DSP/SC though. I know you know this, but for $375 you can get custom tuning and the SCT programmer from Hemifever. If you go custom, thats the route i would go.

Me neither on a dsp/sc stack. I would stick with sct/sc.

 

[Silverbullet08]

right. if i have to go the custom tune route i would go with hemifever on sct. started it the first time today an hour ago and drove to class. first 3 stops it would hold and not stall then it stopped and holding and would stall at lights after that...

ill try recalibrating the tps bc i did take of the tb to clean it...

 

[Silverbullet08]

after i reset the tps

 

[Hemiguy0302]

What the ****. I have no sound on my garage computer but lets say if you try to hold it at 1000 then let it down slowly can you make it idle cause this looks like what my car was doing. Maybe try another calibration and make sure that a floormat cannot impede full pedal travel as well. Anyone else got something here?

 

[Silverbullet08]

if i hold it sometimes it will stay but it still with stutter like that. sometimes it finds the idle sometimes it doesnt. i really wish it would stay idling around 8-900 when i first start it.

 

[Hemiguy0302]

does having the AC on bring up the idle or stabilize it?

 

[Silverbullet08]

nope not really ive tried...
