DynoTune? Why?

[bucket]

whats the point if you cant adjust anything...:confused

With the right equipment
Ostrich 2.0 : The New Breed [OSTRICH_2] - $175.00 : Moates.Net
you can adjust anything set by the factory; in real time while you are driving or on the dyno..
How do you think guys do custom tunes on modified engines.

$175 , a old laptop and some free software gives you access to the stock computer (before '94 ) Later LT1 cars can be done using different but similar setup
You as a uneducated tuner at home can delete VATS , delete EGR ,change fan temps , change convertor lockup speed ,idle speed, anything.
You can change anything to do with the running of the engine but it is a steep learning curve best left to experts unless you have a lot of learning time.
I'm five years in and still using training wheels.

Cheaper alternative , but requires chip adapter for ECM and removing the chip from the car, downloading tune and replacing

thats all very nice stuff. but that just isnt what im asking..
in the mean time the dyno tunner guy filled me in..
they will optimize the air fuel mixture and wot etc shift points and lock up and stuff like that..
kind of like what you are saying except with a stock corvette. thanx for the response

Confused ; what were you asking?

In a 92 , they still have to reprogramme the removible memcal in the computer somehow because the flash memory didnt come out until 94

you need gear as stated above

Vetteoz answered you correctly, a dyno tuner will be using that type of gear and you are hoping the dyno guys of choice have experience with various makes models of ecm's. The only way to tune a computer controlled car is with that type of equipment and reprogramming the eprom in the ecm.
Having a totally stock motor dyno tuned might provide some hp (don't expect the moon) gains, but the biggest improvements would be if they tuned Closed Loop (for typical street driving) and not just WOT.

the guys working on my car are the guys the dealers take their new corvettes to for service..they do total restoration of any year corvette...they work on nothing but corvettes..i am going to have faith that they know what to do..they will dyno tune my 18 year old baby and restore the settings to factory specs..and make sure that it is being all it can be....:cool
they did a check up and advised me what i needed, in the way of maintenance and recommended various treatments..

I've got the type of equipment that requires removing the flash IC from the ECM, and using a programer to erase and write new tunes.

I'm a good 3-4 years in, and still have barely scratched the surface. I imagine that it is much easier on stock motors. I'm sure there are proven adjusments that all tuners make. I know all motors are different, but on all stock applications, the proven techniques will get close.

On a custom application, the gloves are off. What I thought my motor needed was exactly opposite of what I was giving it. What a viscious circle.

So what did they recommend for your 18 year old LT1

the engine guy said it had been babied and was in good shape, with 120,000 miles i wondered..but, it has excellent oil pressure and the oil is clean..
he is going to clean the throttle body, its gummed up a little...and set the mix, and whatever else there is, when i get it back ill detail the service , in case anyone in this area doesnt know about these guys..
so far, no negative feedback..
ps.
the service manager said that i will love the car when i get it back...whatever that means(his response to the dyno tune)

Hey, Bucket, not to hijack this thread, but if you search the Internet, Street Thunder Magazine, did a LT1 396 build and it made 550hp and i think close to 500 ft-lbs of torque with a torque curve as flat as a table top. Sweet!!! C6 Z06's eat your heart out.

Man what you guys don't know about the LS7 won't hurt you.

I won't even both asking if "Street Thunder's" engine's power rating was SAE Net or if the engine would pass emissions certification.

that would werk



til ya got to tha first curve.
then that 1.04G's thing kicks in...

that whole going around corners thing is a big deal..
.and it's got a G guage in the heads up
i want one:cool

that looks most rightous, good job

I doubt they are SAE net or would pass emissions certification but my point is that given the right build up of an older engine with proper gears 4.10's for instance and a driver that can get'er to hook, a C4 could surprise a C6 Z06.

For example, check this out...YouTube - jonecap3's Channel That IS Z06, territory, this however YouTube - jonecap3's Channel is Z06 killer territory, and I bet he has less money in his Vette than a C6 Z06, new or used.

I know all about the LS7, what an engine, heck the LS family for that matter, is the fill in the blank!!! It would be better in just about every respect to the built LT1. You just can't keep a good small block down. Not trying to be little the LS7, Lord, knows it is a cam swap away from BIG TIME HORSEPOWER, very huge potential. I am trying to get a little more respect for a very capble older powerplant however.

Two saying ring true here: There is NO REPLACEMENT FOR DISPLACEMENT, and How Much Money You Got=How Fast You Can Go

Its all about the Bang for Buck Ratio, if I can run with a C6 Z06 for 20K versus buying one for 50K or whatever, which one do you think I'm gona do???

For the record, I realize manufactures have to meet emissions requirements and the fact that they do this and make engines as capable as the LS7 is a testament to the engineering prowess of GM. However, I am not a manufacture and I don't live in a emission test area, therefore, I don't give a flying rats @$$ about emissions, by a flipp'in Prius if one is concerned about emissions.

Hope this makes sense...OK
