Better tell those NASCAR and Formula One guys they need to step up their game to Mass airflow sensors ROFL

Also one added bonus of using the stock ECM is the use of a Mass Air Flow sensor as part of it's programming, which 99% of aftermarket ECM's don't use.... What these aftermarket ECM's use is what they call "Speed Density" programming, which is basically the same type of EFI programming that the OEM's used back in the 80's, so you might want to ask yourself why are your wanting to run your car on 30 year old technology that is really no better than a carb........
I think the guys over at Mass-Flo say it the best...... They are the only aftermarket EFI company to offer their systems with MAF programming.....
Don't settle for empty promises, GET REAL RESULTS! The other companies make it sound as if it's a benefit to have the ability to "tune" their systems. It's NOT a benefit... IT'S A HASSLE! The reality is, programmable speed density EFI systems are not much more efficient than a 4 bbl carburetor. You're punching keys on a computer, rather than turning screws and changing jets and springs in a carburetor. The end result is an expensive system, that cost almost as much money to get tuned properly as the initial cost of the system. And where is the advantage? They require constant laptop fiddling to keep running properly. You could have gotten that with a carburetor! They are a little more efficient than a carburetor, but not enough to justify the cost.

I really enjoy reading the posts about the MS system and its abilities and I
think it is something I would enjoy, but the reality is I think I would be in
over my head. I don't have any immediate plans for an EFI swap but the
idea of swapping in a 4.8/5.3 with a single turbo that makes more power
and is more drivable than an old school sbc is very attractive.
So in a nutshell the HPT trades some power and ultimate tunability for
ease of installation? Fair statement?

If you go with HPTuner's I suggest joining the Tuning School, their manuals give you step by step instruction on how to tune your car with HPT.... Also it supports up to 3 bar speed density or 1 bar MAF and you can add Real Time Tuning......
The Tuning School is an industry leader in High Performance Tuning Knowledge. We teach a safe and effective system on how to properly tune and get the most out of your vehicle. We offer learning through a variety of proven methods - including learn at home book courses, online training, and hands-on classes.

HPT makes the OEM computer a LOT more usable with turbocharging and high output combinations today than just a few years ago, thus it's popularity. GM spent millions developing the drivability tuning that's already in the computer, it's wise to take advantage of it.
My opinion is there's more power to be had with a standalone like the MS or Holley HP / Dominator, but it take a little more work and is a little more "DIY" in nature than making adjustments to the OEM computer's calibration.
With HPT, if your turbo plumbing isn't leaking and the mechanical bugs are worked out (not as easy as it sounds), one $200-500 trip to a chassis dyno might be all you need to have it tuned properly, - however learning HPT yourself isn't too bad IMO. The standalone will be a little more configuration and wiring work, and will definitely be more intimidating at first startup than the OEM computer re-tuned, but is better in some applications than the OEM computer.

How much tuning really?
I see a lot of articles/videos of LS swaps that involve turbos. Many of these
use the HP tuners as the means of tuning the engine. Most of my EFI info
I get from this site which usually leans more toward the stand alone ecm
like the MS. That being said, how much "tuning" is really involved with the
LS turbo swaps? Just curious. Some of these builds are almost to good to
be true and would like to know just how much work is involved after the
hard parts are put together.Tags: None
