One of the issues we are faced with is we had planned on rewriting (and maybe simplifying) the custom OS's for the GenIII PCM's from 98 - 08.
There is a number of technical issues with the later PCM's, the first and major problem is there is no room left in the calibrations area of the PCM, so we would need to move any additional tables we add out to another section of the PCM's flash memory, this unfortunately means a full reflash anytime you wanted to make a change.
That means a much higher risk of a doorstop PCM and a reflash time of about 3mins, not 30 seconds per change.
I think I have come up with a system that can work, but we don't want to try to implement it in the Version 7 software as it will require a lot of changes to the core of the program, something we don't want to do when it is going to be phased out this year.

I am still using V1 with 7.5.5 and COS5. Will I have to upgrade to V2 or can I still use 8.0 software with V1? I am going to be layed off in a week or two and need to save my money.
Thanks.

Bill,

The current V7.5.x software works with V1 (which already does BBL from the V7.5.x software);

The current V8.x software is for doing BBL with V2 (currently beta testing)...

In the future the V8.x software will eventually include everything (scantool, tunetool, BBL, BBF) and will replace V7.x software for V2.

V7.x software will continue to support V1.

i.e. you can run the latest V7.5 software on your V1... you don't really need V2 unless you're flashing an ECM that is not supported by V1...
when the eventual all-inclusive V8 software comes along, you will be able to run that on your V1.
Correction: see post #265 below (V7 will always be available).


Too bad about your job, hope you can find work somewhere.

Cheers
Joe

Does that mean the 98 OS 19980200 will work with that? Is that a miss print. I hope not. Anyway, is that the case that V8 will replace 7.XXX and work with the V1. I do not have the V2. I really like the computer and am looking at the newest small windows based PC's with 9 and 10 inch screens (they are down to around $300.00) to build into my dash were the stereo is and be able to use EFILive and the iPod setup too with a pad and keyboard were the compartment in between the seats are. With V1 this winter along with the 98 to 02 PCM conversion. Nothing fancy though as it seems really straight forward but very time consuming.
Please let me know as winter grows near as does the snow (a little over 2 1/2 months).

Are you asking if the V8 software will work with a V1? It will completely replace the V7.5 Tuning and Scan programs. For your future carputer and iPod integration setup, honestly you will not need a V2 as your V1 can BBL a little and the rest can be done in passthru mode straight into the V8 scan program.

Ive heard the 98-02 PCM swap takes a weekend to do especially copying all the tables over in EFILive but is so worth it.
