Caterpillar XXXXX.fls flash file writing

[leighsus]

I'm unfamiliar with alternating/rewriting existing .fls files...
If anybody is already doing this could you point me in the correct direction... I have figured out how to read .fls in IDA PRO some what rewrite .fls files but its more like cutting and pasting to make a file. I'm trying to accomplish 1000hp ecm flash file..

Hi there, I am a noob here, but I want to be an active contributor, I don't know how to do what You requested but have the big question for You, Why would You go to 1000 HP?
Remember that the engine and components are designed to withstand certain specs and when You go beyond them something bad it's bound to happen.
I would like to know what kind of engine are You going to blow away with that kind of power if You are able to achieve.
Are You a Cat Tech?

[leighsus]

If I was a Cat tech I would not be asking for help...
The company I work for has a few engines on the
road. one is a 6nz 750hp to the ground pete that
makes stupid mpg by controlling the fuel. temp, flow,
transfer pump, fuel heater, fuel cooler, evans waterless
coolant, fuel mode, trim codes adj to flow exactly the same,
extrune tips, custom built injs, too much to list

1000hp is just a number... It's the driver behind
the wheel that controls the out come of the engine.
Some ppl buy pp for the power, they use it for the
power and it just doesn't last. I do everything to
save fuel (MONEY)

I know two guys who have done it but they won't help. If anyone has advice please PM me. I am very interested as I am working hand over fist to figure it out.

I think the guys that are modifying the fuel tables and timing with the Cat flash files are using a Cat flash file editor program. I've never seen it before or heard of whats its called.

Hello again leighsus, and Happy Holidays for everyone.
I beg to differ on Your CAT Tech comment, cat techs are not the maximum authority on cat mechanics, they have all the information available and a ton of tech support, but more often than You may think cat techs have to ask tech support for help.
I know You are all about saving money, and I understand and respect that, but first, the most horse power You want out of your engine, the more fuel You will consume, regardless of any fancy upgrades or custom components you may install in such engine.
Second, if you really want to get more HP out or your engine on a safe way, visit your local dealer and request them to get the file for you, they have to get it from factory anyway, since the file has to be written specifically for the individual engine, it may cost you some money but in the long run you will save on parts and repairs compared to going the "hacker" way, the file will be written so the HP can stay within the CAT engine specs.
Now, if you really want to save fuel, keep your engine stock, service your rig properly and drive at least 5 miles slower than usual, that will save a lot of money with time.
It's working for me, it has for the last 3 years.
Also, I will recommend you that use Cat filters and oils, they may be more expensive, but you get more life out out them and your engine will stay cleaner, aftermarket filters and oils are good, but not as good as cat's.
Any way, that's only my humble opinion, I don't mean to upset you or offend you by it.
Happy NEW YEAR!!

I`ve also heard about the progam, master cat et or flash file editor but I can`t find any info about it.

jrdztech. Your obviously not a fan of After Market Parts.
Well It's my buisness and how I make an income. So, I can't stop. No offense taken, But watch me closely I change stock drivers in to aftermarket drivers every day.

[jrdztech]

Hello Leighsus, It's not that I am not a fan of aftermarket products, I know there is a lot of them out there and some are very good, in some cases better than the original part.
Till today I believe in brand names because it has worked for me, but I am willing to be educated on that matter if You want to teach me.
Have a great day.

I think editing the Cat ECM files is possible with sofware like WinOLS. I am going that direction but its brand new to me.

No offense bud but I'm willing to bet if I got my hands on your ECM you'll take that "CAT" programming and throw it away. First of all you CAN (I do it all the time) take that CAT and increase horsepower AND IMPROVE fuel economy at the same time. You can take a MBN 475 CAT and put out over 600hp's while increasing fuel mileage over 1mpg!
Second, going to the local CAT house and requesting a file for your truck isn't going to put you any better than the truck was to begin with from the factory, as a matter of fact an updated file will more than likely be worse on your engine regarding efficiency. Take an old truck and have it updated with a low-nox file and you'll get my point on that. ALL engines in the same family rating have the SAME program written as far as flash files. Two of the same engine that share the identical Test Spec number and Arrangement will share an identical Flash File. They control the minor fluctuations in horsepower,torque,and emissions using the FLS and FTS settings in the ECM, not the FLASH FILE. Lets see, your pretty close on the CAT filters though, even though CAT has only one plant that makes their own filters it's still managed by Donaldson Co. It pretty much starts off as a Donaldson filter but there are some minor changes made internally to tighten up the specs just a hair. Hope I was of some help...

I hate to say it but, I have nothing but problems with cat fuel filters not flowing after 2 or 3000 miles. Low sulfer fuel stinks!! I now use baldwin or fleetgaurd. Really would like to figure out how to edit a file though. Somebody must know something!!!!!!!!!!!

PM me for file editing if interested....

Well I understand your filter problems as I hear it all the time, BUT, a filter that quits flowing after 2 or 3000 miles is ovbiously doing what it's supposed to do right?? FILTERING the contaminants.

I would agree! I dont believe you can beat the quality of the cat filters. Been using them for 20 year only had a problem with one oil filter that busted inside and cat paid for the engine. As going to the cat house for flash files I agree with Chris.
