Wow, guys! You don't know what you are missing out on. check out tunercat.com it'* the software i use. you can change fuel maps (not recomended unless you know what you are doing) but you can aslo turn features on and of. (EGR, ABS, ect..) and you can also regulate your boost.

I just want to know what are all the parts required for the Bonnie.

cheers!
Eric

I do pretty well with my Jet stage 2 chip. And I regulate my boost at 12psi with my right foot

Good luck!

Good morning everyone!
Well i dough up more info on the eprom programming if anyone is interested.

Taken from Rockraw:
Most GM ECMs used until 1995 have an Erasable Programmable Read Only Memory (EPROM) that stores data about the particular engine it controls. Some EPROMs also contain information specific to the transmission and the car. The EPROM is often referred to as the "chip". The chip is sometimes located in a removable carrier called a MemCal or Calpack. To edit the chip, you will need a few things. You'll need a PC or laptop computer, since you are reading this I'll assume you already have one. You will need an EPROM programmer or device programmer that is compatible with the EPROM in your ECM. You will need an EPROM eraser, most stock GM EPROMs are erasable and reusable. You may also want to have a few 'spare' chips to work with. And lastly, you will need editing software that supports the ECM you are using. It takes some time to learn how to use these tools, and it takes some money to get started. Unless you can make use of it on several projects, you'd be better off just finding someone who can do it for you.

What you need:
Needham'* EMP-10 device programmer. It is fairly inexpensive and covers all of the EPROMs used in GM ECMs. Visit http://www.needhams.com/ for more information or to order one.
Datarase II EPROM eraser from Walling Co.. Erases four chips at a time. Most inexpensive eraser I could find. I bought mine from http://www.digikey.com/
GMEpro editing software from Terry Kelley. This software has coverage for lots of different vehicles. Excellent tech support. A shareware version of GME for the 85-88 V6 Fiero can be downloaded by clicking here. Contact Terry at [email protected] to purchase the fully functional editor and .epe files for other ECMs.

For the editing software, use GMEPRO or TunerCat

here are the immages of the memcal adaptor for the programmer. this help in downloading your eprom info. (fuel maps ect..)



Still digging up more info!
