ok im about to the point im ready to turbo my car im going to use a msd dis 2 box to retard the timeing. as for the fuel im going to run a vortec fmu, afpr, and a wide band to tune the fuel
is there anythanf i need to do to the map senser seens our cars are not made for or set for boost
this is just a part time set up will be buying hpt and tuning it rite the end of feb next year
id say have some patience and do it all at once.
i would not boost at all without any form of tuning on it. not worth it.
what if i was to make a missing link setup for now
Wait alittle now(with a car that still runs) or wait longer later(with a car with a blown engine). Your choice.

"technically" it can be done with an FMU and AFPR. Though I know some ecotec PCM's don't allow for this unless tuned. If yours isnt the year that does this you should be ok. Since youre using "third party" fueling parts that don't need a computer to control them, the MAP sensor can stay stock. You will need to change it for when you get it tuned though I believe. Your stock PCM isn't going to control anything regarding fuel when you hit boost until tuned.
people used to boost cars before HPT. Though I would use larger injectors (you didn't list those for fuel)
However that said, I don't know if I would do it. My turbo setup has been on hold for like almost 3 years now because I am trying to acquire the best parts for it. Originally I was going to do it this way, but HPT came out for our cars like the week before I was going to build my setup. (since then I have made bigger plans, but the availability of it stopped me dead in my tracks)

No tune = Potential damage. Just wait for all the parts and then boost it.
Using a FMU and AFPR isnt really a tune for a computer controlled EFI car.
Those are old school methods for muscle cars, which where carburated, so being close was good enough.
well im going to run a Gm Supercharger Reflash for the time i figer with a wide band and the stuff i got i could get the car to run better this route
A msd is not the way to retard timing, use HP tuners for that, and if you use alky injection alot of times you can add timing

I can save you a fair amount of money based on what you propose here. First off, will this be on a stock or built engine?

From your pics it looks like you have a 95-99, you can get a 2000-02 computer and swap engine wiring harnesses, this will allow you to run the GM supercharger reflash which also allows you to run a 2-bar map, much more efficient than any other way of doing things. HP tuners is a breeze from that point forward. Theres always of course a stand alone also. Thats prob more work than you want to do.

from his profile he has a 2002 Ecotec. Only thing in the picture that looks 9599 is the bumper. Headlights suggest 00+.

i would go with a gm supercharger reflash or an additional injector controller. these 2 choices will be the cheapest. lose the idea of a rising rate fmu. purchase a 1:1 fuel pressure regulator instead. one psi raise in fuel pressure for every pound of boost.
my car is a 02 the motor and trans is out of a 04 sunfire has 41xxx on them now
i talked to a guy i knew at a dealeship here hes going to hook me up with the gm reflash thursday

Dude, I am running a boosted 04' Cavalier.
When you throw a GM reflash on a 2003.5+ PCM, it will LOCK IT. Check the stickies. I believe it's either 14 or 15 psi. HP tuners will not be able to do anything about it.
I HIGHLY suggest that you go to your dealer with an 03 VIN, ask them to flash it to the STOCK 2003 progam. Then, go out and buy HP tuners, and build and boost all you want.
Your main concern is the 14.7:1 AFR's with the 2004, and the 2003 stock file will fix that problem. Check my profile, best $75 I ever spent.
Woah, Ninja post!
^ ^ ^ ^ ^ ^
I just noticed, if you are running the stock 2002 PCM, and haven't swapped it out with the new motor and trans, then DISGREGARD my above post....haha
Wow, it's late for me!
Boost without a re-flash is like having sex without a form of contraceptive; expect the inevitable.

This.
"the clap" or "the knock" is kind of inevitable
