AF vs SilverBullet Showdown

[truckin151]

Hmmm.... Pull the t-stat i guess, I've always heard that with the lts and sc it leans you out. With my Lt's and DSP it leaned me out a lot.

how does a thermostat have anything to do with fuel mixture? i have my sc p&p tb and powerwire it seems to me that my truck runs better that way....im just asking cause i dont understand....

 

[truckin151]

It makes the truck run cooler and because of that increases the amount of fuel than normal. When doing LT headers it really needs it as most tuners will make the combo run really lean and adding the 180* T-stat helps that. For whatever reason though his is running pig rich (well richer if its dumping that much fuel in there), wonder what the A/F is at WOT though. Teach's truck is running rich too but I beleive his WOT is basically perfect.

aaron u remember where the stock one is? couldnt find it. doesnt matter now im back at my house. i had to catch my only ride to it. problem is i have class all day tomorrow and wont get out till 7...

 

[Silverbullet08]

i really think its just dumping way to much fuel at idle causing it to "flood" and stall out

Mine runs LTFT's around a -20 at idle and part throttle.

Mine right now runs LTFT's at -7 at idle and 0 at part throttle with the stock cam. Guess thart cam adds a bunch of fuel.but not nearly as much as what bullets is doing.

Stock Tstat was trashed. It was busted anyway. Get Sam to help you hook up that psc and work on fuel trims with that

 

[Silverbullet08]

alrighty...

 

[Off_Road_Teacher]

Were your trims a positive or negative 27-32?

 

[ramhunter9]

AF is there a partial refund coming nicks way ?? lol

 

[Silverbullet08]

positive...

 

[glass3222]

positive...

I don't think you are getting fuel.....+ are lean and - are rich I believe.

 

[Off_Road_Teacher]

positive...

So the question is why? Those trims are the exact opposite of mine despite our similar setup. That thing should be pulling fuel not adding it.

idk. ive been talking with sam. he wants me to finish the exhaust up. which i agree. just need to find a way to get it to a shop. he said he will look at it though

 

[truckin151]

Possitive means he's running lean, negative is rich

 

[truckin151]

So you are not getting fuel

 

[Silverbullet08]

so how do i fix that?

 

[truckin151]

Good question. The 180* stat should have added fuel, but teach's setup is doing the exact opposite with the same setup. Its just odd.

 

[truckin151]

A powerwire would add more fuel too.but still its just odd
