I was condsidering going to a speed density setup but i was just wondering what are some of the disadvantages with this set up?

F/I car it almost a necessity..Unless you are a max effort car I wouldn't bother....It is expensive/time consuming too.....

If you're stock, what's the point?

Or are you..."stock"?

They allow you to elliminate any restrictions in your intake setup, but on a near stock car that won't do much. They're pretty sensitive to weather and altitude changes.

Why expensive? Do tuners charge more for SD tunes?

SOMbitch

Yes. More time involved......

imo its a much more thorough tune, more spot on....but if your car is a day to day dd, or winter too the weather changes probably wouldnt be very good..

That's ****** weak. Tuners already charge $4-500 for a tune, I don't see how they can justify charging more just to tune in the VE table

well my car is "stock" but not stock put it this way it sounds like a damn vaccum is in the intake lid, and before i go spending $$$ on a fast intake, i was wondering if its worth going to speed density, i got really good "stock" heads and a great built "stock" bottom end but straightline told me the ls6 intake is holding the car back, the car is driven on the road but only in good conditions,

if your doing a normal MAF tune why wouldn't they tune the VE tables?

My 92' V6 Camaro was speed density. I've had four cars since then, all of which had or have a MAF (86 Olds Cutlass Ciera 2.8, 88 Pontiac 6000 2.8, 97 Olds 88 L36, and my LS1). I have to say, that 92 ran the best out of all of them. I swear the lack of an unreliable MAF sensor had alot to do with it...

You should, which is another reason I can't see anyone charging more for a speed density only tune, hell they wouldn't even have to mess with the MAF table so really it's not harder at all. However most tunes I've seen from "pro" tuners, they don't even mess with the VE table.

The MAF is very reliable and accurate as long as it's not pushed beyond its capability.

I drive my Open Loop Speed Density tuned car, from 4500 ft. to 10,000 ft. in 0 degree wheather to 105 degree wheather and have no fueling issues what so ever.

The IAT sensor deals with temp. and the MAP sensor deals with altitude.
These sensors remain intact in a OL/SD tune and deal with any changes for temp. and altitude.

If a vehicle does not run correctly when the altitude and/or temperature changes, then the tune has not been done completely/correctly.

that is what I have heard also that the temp/alt thing is highly over played...

I find that hard to believe that through those dramatic atmospheric changes that your fueling did not swing at all in open loop

The tuner I talked to around here gets $850 for a SD tune.....

Wow... that just seems ridiculous.

Jesus ****...my tune was $400 regardless...MAF or SD
