I have heard there are many Free LT1 PCM editing and diag softwares available.

Does anyone know where to get them and where to learn about them?

 

www.tunercat.com under $100 and your set. Using something free will cost you $100 a pop "with core" if you scramble your pcm.

 

We'll I figured if I could get it on my laptop I would be able to use Diag software in real time.

Then be able to Mod the PCM based on that data.

it's only an eeprom it's not that difficult to work with.

Plus I already found pcmcomm.exe and pcmread.exe for free.

I'm going to make the connector this weekend.

 

I think the hard part is editing the bin code; anyway you have a 94 so it's a flash based pcm no eeprom sorry, that would be to easy.

Lots of people can edit a .bin for you tho if it's basic stuff.

But to answer your question 'that i failed to before' i've never seen a shareware/free editor for our cars.

As for realtime, again never seen it done; older cars might work with a romulator but if your after realtime tuning it's a f.a.s.t system or something similar.
