Getting started

Ok, so many of you may or may not know that i have installed a chevy 350 in a mazda miata with 2 eaton m90's strapped to it.

i have a 16196395 computer, moates g1 adapter, a N/A chip from mark, BURN2 unit, and an ALDL cable.

A little background about the engine:
Crate chevy 350/330hp
http://www.summitracing.com/parts/nal-19210008

blew it up, rebuilt it, converted it to TBI and added 2 blowers to it

No smog stuff, and no a/c ..... just the necessities to make it run [IACV, MAP, TPS, Coolant Temp, Oil Pressure]

t5 manual transmission

Right now it is on a 350 throttle body and 350 injectors..... believe its 61pph..... removed the OEM regulator and installed an aftermarket unit so i can adjust it.

2 bar map sensor

wideband o2

I now think that i am ready to begin tuning. The car runs and drives but i do NOT want to take it into boost until i know what im looking at and everything looks good.

I have tunerpro installed on my laptop and have no clue where to start at especially with boost in play. I have marks bin file loaded from the chip he burned for me.
I have watched some videos on youtube about tunerpro, but that still doesn't put me in the neighborhood of where i need to be at.... i learn fast so if you guys can explain things, ill post pictures and give you detailed information on how the car is running and what the wideband is saying.

Thank you so much for your help and this shall be a fun experience :D

PS: I do not have chips YET, but can i run a "tune" via the laptop without ostrich or chip swapping just to see how the car would react or would i need to burn chips every single time?

Each time you change a parameter, like a fuel table cell, you need to modify the .bin file. The modified .bin file can be uploaded to an Ostrich 2.0 or Burned to a chip, your choice.

For an application like yours, an Ostrich 2.0 is a good option because uploading to the Ostrich 2.0 is quicker than pulling a chip / then installing an undated chip every time you want to change a parameter.

Alrighty, i messed around with it for HOURS trying to connect to tunerpro..... messed with com ports and everything, wouldn't connect. Tester said it was reading perfectly fine. Tried a new .adx and .xdf file and connected great.

now, like stated before, where do i begin?
can i delete all the trans, a/c, egr stuff in the xdf file since my car doesn't have any of it?..... simply just to clean up the confusion that is overwhelming me lol

i can also do a "naturally aspirated" log so you guys can see where the car sits with marks file and then go from there hopefully leading to boost.
I will buy an ostrich if its really necessary. I think i'll be here for quite a while trying to get the basics down and learning whats good/bad for the engine, etc.
maybe tuning naturally aspirated at first will be better. I don't even see the boost tables in it.

Here is a screenshot so you can see the ADX and XDF files that im using now since it decided to connect

See if you can connect with the attached .xdf & .adx, which are updated versions of what your are currently using.

You won't see boost tables. You have to "Trick" the PCM into seeing boost with a 2 Bar MAP sensor.

You can disable EGR a couple different ways; Set EGR enable temperature to 151 C.

Set EGR enable speed to 255 MPH.

I set "Manual Trans" for the following TH350, TH400, NV4500, NV3500, T56, T5 ect.
