Stupid Fuel Question

[JTS VENOM PERFORMANCE]

First off our trucks come rich from the factoryas a detune, so as to save the vital componets ie, tranny's and clutch.

Second the flash takes away this, adds timing to lean out the fuel condition, thus more power, more efficiency.

Octane rating is how fast or slow the fuel burns, plus with the timing from the factory lower octane ratings will cause detonation, although on 05's this can be resolved with the knock sensor.

When you get the computer flashed, it adds timing and proccess the fuel delivery different from stock, to give the engine better performance. Therefore the advance timingto where if 87 , or in that area octane is used detonation will occurr.

With a flash it is best before you order your flash to tell them what octane rating you have in your area, with that you should not have to worry about detonation.

hope this helps

Thanks Smoke..that helped me alittle. Looks like a flash might be in order. If you gain 80hp it would seem that this is a good mod. I have a Magnaflow and might put on some headers. Not sure what ones to get though. Bassanis, Belangers?...
About the only other thing I might do is a powdercoated intake..would like to go polished but thas alotta bucks for something that just looks pretty...lol

Flash + 87 octane= BOOM!!! ?

Thanks Tony..

Hey Smoke,
Thanks so much for the info, man that was a lot of words! LOL

It helps me out a little, but still kinda cloudy.

The exhaust I get. If the sound is what you want, buy it.
The computer not so clear. I'm trying to get a handle on what are the
advantages of all the different upgrades. I am going to stay with nothing
more than CAI so any direction would help me out.
Thanks again,
MN

Well a PCM will benefit you. The timing will be adjusted to lean you out so you will see some HP and TRQ gains. You will see more power gains in the lower RPM bands. In other words at 5000 RPM's you wont see much power gains. But at 2000 RPMS you will. Your fan will come on sooner to help keep the truck cooler. Cooler truck equals better performance. So if you only plan on doing the basic intake and exhaust then the PCM flash will suit you well.

This question could take a while to answer....

First let's start with the octane rating of 91 vs 93...this number is mostly determined by the area you live in and its emission requirements.

Rich vs. Lean...

the brass tax is you have a fuel MIXTURE than is being injected into your motor....that is a mixture of Air and Fuel thus the A/F ratio... the lower the number the richer the mix (more fuel less air) therefore 11.2 is RICHER than 12.0

Now here is where the Silverbacks and Fstjacks need to take over..when you are rich....you are leaving power on the table (unburned fuel) = black tailpipes....at this point you can add timing and take advantage of this extra fuel in doing so you burn more fuel...generating more power and leaning out your A/F ratio....go to far and you get detonation and we call you Blake..

like I said there are another 100 pages of info here but this a over simplified start that even I could understand...

I'm just shocked you didn't include the wing to no wing ratio.

I ran 87 to 89 octane for the first 9K miles and ended up with a clogged cat. It's always 93 for me now NO MATTER WHAT.

The PCM flash, Boomer, Mopar:dontknow:
DC from what I've read is for a more upgraded truck than what
I am doing to mine.
Any recommendations would be helpful.

Man I miss a carb and distibuter. :stupid:

LOVE my truck, just need alot of info to upgrade.:withstupid:

Flash stick to Boomer or DC. They are good for stock trucks to heavily modded so no worries.

Dont miss that carb......would rather hook my laptop up and spend 30 mins on the dyno...than swapping out jets, and dicking with a timing light

Both DC and Boomer will adjust the flash for your mods. So when you order your flash you just tell them your exact mods and they will adjust your flash as needed. I got my flash from B&G so I comment one way or the other as to who is better between DC and Boomer. Probably about the same. Just give both a call and see who has the PCM in stock and can deliever first.

Thanks for all your help.

If you have other questions or need some more help understand about flashes then post up. We all had to learn sometime. 18 months ago flashes were just coming out, kind of like nowwhat and his closet.

That makes two of us Mike.

BTW, Believe it or don't, my gas mileage went UP after installing my Stage II from Boomer. And it ain't because of the way I drive it!!! :burnout:

Maybe this has something to do with the way the flash leans out the mixture, making the fuel burn more effectively? :dontknow:

As I recall most people got better gas mileage from the flash. Better gas mileage and a faster truck. What's not to like?

 

[MikeNice]

I guess I'm limited to a "Stage I" cause I have to shift the truck myself?

Would this be almost the same a "Stage II"?

You can get a stage 2. Stage 1 was for less then 93 octane and was not as aggressive on the tune. I have had both stage 1 and 2. The stages are not assigned by 6 speed or automatic. The stage 2 is just more aggressive but towing is not recommend and you need 93 octane. Since you have a RC and probably don't tow anyway, go with the stage 2. If you don't have access to 93 octane fuel then tell them when you order the flash so they can dial back the timing some. Read this http://www.dcperformance.com/chips.htm

After reading some I don't know if you can even get a stage 1 anymore. When they first came out there was stage 1 and 2. Now I think they are all the same and they just adjust the flash for your mods and octane of fuel.

Read this one also. http://www.bgchrysler.com/Service/High_Performance_B_G_Flash/high_performance_b_g_flash.html

B & G said that they got 80HP. There is that much in the the "little black box"?

Is the B & G the same as DC?

PM sent.

From what I can remember BG came up with the flash (stage 1). Then DC took the flash and made it better (stage 2). Then they teamed up. That is why BG's web page shows the stage 2 flash and its gains through DC performance. Now the 80 HP is not max HP. So lets say you dyno with a max RWHP of 450 and 480 TRQ. Then you get a PCM flash. Now you dyno at 460 RWHP and 500 TRQ. Not a lot of gain there until you look at the whole dyno run. Those max numbers you had on the dynos was around 5000 RPM's or so. Now if you look at the lower RPM on the dyno sheet, lets say 3500 RPM and compare the 2 dyno runs you will see that at 3500 RPM's you are putting out 80 more RWHP and 100 more TRQ. So max HP didn't go up much but your power down low sure as hell did. I could sometimes chirp 3rd gear in my truck. For a QC that is a good deal. But remember you have a RC so your gains will not be as much.

Disclaimer- The above power numbers and RPM's were only used as examples. Actual gains, RPM's, Max power numbers and any thing else I may have messed up are not my fault.
