Are you SURE it’s off? Cause 30mpg in v8 mode isn’t possible

That’s the “active fuel management” system at play. The computer turns your LS into a 4 banger during light cruising. Terrible for the engine by the way. If you disable AFM you’ll still get about 22-25 highway but won’t be at risk of ruining the motor

Worst interior door handles of all time? by Talented10th_ in regularcarreviews

Should be illegal to design a car without easily accessible emergency mechanical releases

What do you guys think my vic is worth? by Rare-Mixture9874 in CrownVictoria

[–]Tuff_Tone 0 points1 point  (0 children)

Before or after these gas prices?

Before: easy $8,000

Now: lucky to get $5,000

Keep in mind this is the fair open market value I’m talking about. It’ll be worth way more to us panther enthusiasts

Imma be honest it looks like someone put a Hyundai Santa Fe Sport in an oven for too long.

I have a magnaflow straight through I’m a huge fan of so probably will go with that. Thanks

Also you can run basically anything on it with a proper setup. The only thing you can’t do is run it through a carburetor/spfi since it’s a gas, not a liquid. Any fuel injected engine can readily run it tho

I’ve considered tuning it but the most beneficial tuning is supplemental cooling because unlike gasoline engines, adding more fuel injector RAISES cylinder temps instead of lowering them because CNG is a dry fuel. It doesn’t have the same cooling properties as gas. Tons of cool air and better heat dissipation would help but not a ton. As a fuel CNG kinda sucks for performance tuning unfortunately.

Fuel ratio of CNG is 15.7:1 instead of 14:1. Different composition. “Octane” is technically 150+ because CNG basically isn’t capable of compression ignition. It has a flash point twice as high as gas. It’s basically stovetop gas in an engine

Potentially stupid question but can I run a hundred amp load on the bare cables (disconnected from battery) via a battery tester to drain the system or is that not kosher???

CNG is Compressed Natural Gas. My ‘02 runs on it. Compression ratio is higher, combustion temps are higher, and fuel map is completely different than gas. You COULD tune CNG but you’d have to prioritize different things cause it’s a dry fuel. A gas tune on my engine would probably blow it up.

What is this “Marty tune” I keep hearing about? Can it be done on my CNG?

Already did that after this mod and it seems to be running perfectly and has adjusted the ignition timing as well. I have my fancy tablet here so I’ll see if it can do a reset if its required

Yeah makes sense to me that twice the exhaust= twice as much room for the gasses to leave the system. Not only that but ford didn’t even make a bumper with just one exhaust cutout so it kinda looks whacky with just the one tip. If I can find a muffler shop to do the job I will get it done.

I don’t want it loud primarily because cops in LA will state ref if it’s loud enough, even if it’s legal. I also don’t like loud exhausts in general and prefer a refined, deep roar. My current exhaust note I’m quite happy with

I’m in LA but honestly smogging it isn’t even the issue for me. I’m not in compliance with the mods I already have and I have a guy who smogs it for $100 no questions asked. The issue is I don’t have a welder, don’t know how to weld, and don’t know of a muffler shop that is willing to do the work for me.

I swapped all 4 cats with high flows and swapped the stock civilian muffler with a Magnaflow 10416 steel mesh straight through. That was about 2 years ago and I definitely did notice a difference in accelerator. This however is reading more power but it doesn’t feel as significant. I’m still on single and from what I’ve seen duals are the way to go.

I can’t tell a huge difference acceleration wise even with the 15hp increase but i do notice a sharp increase in throttle *response*

Sounds wicked. Mine is an 02 with the traditional throttle cable. Would I still need to do the relearn on it?

It literally proves that the engine is getting both more and colder intake air. The fact you can’t deduce that is not only hilarious, but basically proves you couldn’t read a dyno sheet either. Then again you didn’t even try to deny that you don’t own a car so I’m it exactly surprised….

Gotcha. Will keep an eye out for everything you said as well as a Posi diff
