Questions on software and Eproms

I know it's not a referral service but I have to ask, because I don't want to waste money getting the wrong software. E-mail me if you don't want to post publicly please.
Please keep in mind this is an 86 IROC and I just bolted a Miniram II to it, 52mm TB, put LS-1 26.5 injectors on it, set the AFPR for 48PSI and SLP headers and Y pipe, w/ a comp cams 270hr. I know I need to redo the ECM and delete the EGR and 9th injector and set the Injector size for the new ones that I put on.
Any help would be appreciated

Question 1
Opinion's please. Which Reprogramming software do you prefer (Tuner cat or something like it)?
Questions 2
Is there an EPROM that can be made so you don’t have to pull it out, (i.e. you can flash it in the ecm through the ALDL connector and a laptop) for the 1227165 ECM that can be made to flash? Is this a worthless question? If there is what kind of modifications need to be done to accommodate this if it can happen?

Tunercat for use with the PC, if mobile GMEPRo is nice since DOS based and can use a DOS machine.

I'd seriously think of going with a 90-92 MAP system.

Hot MAF'd cars and new tuners don't always work well together

Grumpy, thanks for replying. I was beginning to think that I was asking the wrong questions.
I was talking to an Engineer here in CR w/ a 87 GN and he showed me a "Eprom Data Table Chart" for his GN. Do you know where I can get one of these so I can look at My tables w/ hexworks and change the injector size, and turn off the EGR and ninth injector as a start?

I missed answering your 2nd guestion.
Anyway yes there is an ability for replacing your eprom with a SRAM, and doing on the fly tuning. But you have to change over to the same wiring as an 808. The 808 is the Australian version of the 165 sans a communication chip. ANyway, Kalmaker out of Australia makes what your looking for and it ran I think 600-800 dollars. Be advised thou they just closed shop once for several months and left their customers with 0 support.

I don't know of a public domained hac of the 6E code.

The 8D of the 90-92 ecms I think is floating around.

What would make a great community project would be fully commenting the 6E, or 8D code.
For one guy to do it takes like 9 months of intensive work
Then you could refine it to Source Code and do whatever you want.
