I’ve heard some engine perimeters in the computer can be modified using the SDD.

can anyone confirm or deny this is true? If true, what can be changed?

 

With a genuine Mongoose, very hard to find, as well as expensive, that i have
Then you need to FIND the V130, IDS/ SDD software to run it.
Which i am having issues acquiring.
After which we are supposed to be able, to do most anything, that the dealer can.

 

You can't just modify things. You could reprogram modules if appropriate.

Be sure to read about the power supply required!

 

modules that control timing and fuel? 👀

or injector and maf scaling?

 

You can do al sorts of things to your car, to customize it.
Programing modules, new, & used ones too.
If they can be reprogramed, this is just another thing you can do.

 

no. You cannot modify the timing or injector timing or maf scaling with SDD. You can change some features and add some optional equipment but you cant change the engine control parameters using SDD

 

pre panpag ecus = do not touch

 

So, then what do we use for tuning?

 

New spark plugs, coils, with air filter, is a good start on a tune up.

 

message alexjag. He does that stuff

 

I really hope you’re not being serious. 🤣

 

As a friggen heart attack, these cars are PLENTY fast from the factory.
Keeping any vehicle in good tune is not a big problem.
Starting to believe you are going to out think the engineers, your looking for problems.
Wearing things out, is WAY different than tearing things up.
Its your choice, good luck with your tune

 

Considering it’s a fact that the majority of cars with a computer come from the factory either running too rich or slightly too lean and that has been proven time and time again by anyone who’s used a wideband O2 sensor and datalogging.

The thinking that because an engineer designed something that it can’t be improved is extremely ignorant.

In subarus the weirdo purists cry “Leave it alone you can’t make it better than the engineers” but the factory tune is trash at best and rides dangerously close to the line of
detonation.

Same thing with the BMWs, purist cry “Leave it alone you can’t make it better than the engineers, yet the factory tune leaves a lot on the table in the realms of not only performance but fuel economy and overall efficiency.

Again... GM, Ford, Honda, Nissan, Toyota... all guilty of the same thing. It’s a globally known fact that oem mapping is trash on practically anything with a computer.

It’s a proven fact more power comes from more efficiency.

It’s a proven fact ANY car with a computer benefits from ecu tuning.

Please stop talking out of the side of your neck. I built my last car beyond double the HP it was stock and beat the **** out of it on the drag strip, no prep events, and street racing for six years and sold it still still running like a champ. Last I heard it’s still in Denver somewhere wreaking havoc.

Newsflash bubba. Those engineers only do what they’re told and design parts based on cost effective models made up by some nerd behind a desk.

In short. When you upgrade you get gains because whatever oem part you upgraded was RESTRICTING the engine. Upgrading and tuning is merely removing the bottlenecks and restrictions that nerf the engine to make the power and performance numbers that the nerds behind the desk calculated was most cost effective and under budget while staying competitive with others in the same market.

Your car is fast enough for you... cool. Mine isn’t fast enough for me... I can afford to fix anything that MIGHT break or go wrong, and I enjoy modifying my car and making it faster so worry about how you spend your money and drive your car and I’ll worry about mine ok?

Nobody asked about reliability or longevity. Nobody asked about the vehicle’s stock performance either.

Nobody cares that you bought an exciting car to do boring things with it. “PLENTY fast from the factory” 🤨🤣

Hate to break it to you bub but, 13.1 1/4 mile is hardly considered “Fast”. Literally... there are fwd 4cyl cars that do that stock. 13.1 is barely, sort of, kinda starting to touch the “Quick” bracket. Lol If you think a 13 second car is fast, you must live an extremely boring life.

I don’t need to be lectured on the dangers of modding bubba... I’ve been building street and race cars my whole life. If it’s buttoned up tight, the tuning is solid and afr and timing is safe, it’ll run for another 100k without issue and it'll do it making more power and getting better gas mileage.

You should have bought a fkn prius. 🤦🏽‍♂️

Now, excuse me, I have a new powerhouse 10% pulley to install.

 

Install what you will, never said you can't make them go faster.
You can, but having more money than brains is not where i am at.
Already had my fun with modifying motorcycles, before you were born.
These are not quarter mile E T cars for me.
But inexpensive used cars, whose resale drops like a stone, only way i can afford an $80,000 car.
Opinions are like *** holes, everyone has one, & they all smell.
When i was 37, was doing the same kind of things.
But found better places to spend my money, as i matured
Got better things to do than lecture youngsters like you!!!!!!!!!!!!!!!!!!!!!!.
As far as a Prius, you can shove it where the sun don't shine, BUBA
As i said before good luck to you

 

I’d imagine your bank account is higher than your IQ with the **** poor reading comprehension you have.

I’ve spent my whole life building and modifying cars. The narrative that doing so takes lifespan off of the car is asinine to say the least. The degradation modifying has on the engine is practically negligible as any mods that do actually shave life off like nitrous or boost, have such a small effect that you’ll never see it in the time you own the vehicle. The next three owners probably wouldn’t see the effects either.

Go read a fkn book and don’t worry about my money. I have enough streams of income and money in crypto and stocks to make sure I can enjoy whatever hobby my little heart desires.

If you have nothing intelligent or relevant to add to this thread, kindly fk off... K? Thx. Bye!

 

The AJ33S supercharged engine is aready finely tuned by the factory.
Not much to gain there.
If you have a lot of money to spend: https://www.jaguarforums.com/forum/x...500-hp-142684/

 

Thats what i thought paydase, but Joel Brown seems to disagree
More money than brains

 

Mr Brown you need to do some ACTUAL research on Jaguar and listen to some sound advice from members on this forum.

Look at the thread in here on Quest for 450 hp Ignore that is states 450 hp and just read thru it and you will see some of the issues involved.

Also if you have an SC car with more than 50k miles you are already detuned substantially because of soft carbon build up.

 

Watching with interest to see what you actually achieve & when.

 

until you get rid of the junk eaton that puts out nuclear reactor levels of heat you will accomplish nothing and you’ll still be stuck with a mid 13 second car
