There has to be enough support for the test so I can pay for the shipping to get another mail order or Allen can just give me one of his sweet tunes free.
I'll try it if everyone wants to know but I want something for the education of everyone else LOL. Y'all can even watch me do it if you think I'll lie
Ok, try it. But I'm telling you, I use the TIS web stuff too, what happens is the TIS stuff can't begin to write it. It recognizes it, just like the obd2 scanner can, but when it tries to write, it just fails.
Anyone that has written over our tune when going to the dealer didn't have a locked pcm.
There is no myth about this to me, I know it can't be done, with the tools I use. If it could, I wouldn't require that customers send in a stock or unlocked pcm as a core return, when they don't, we have to charge $55 because the pcm is useless.
Here's what I'll do, I'm going to send you a stock , newly flashed PCM that has a stock 2002 Camaro OS, GM's latest.
Then, feel free to flash it with any 2001/2002 GMtruck/suv/fbody file you want.
I'll help, here's a 2002, 4.8L Silverado vin to use: 1GCEC14V02Z136510
If you're using the same tools as I am, which you said you are, TIS, you won't be able to flash it.
So, if it doesn't work, what are you giving me, besides knowledge I already know, lol!?
I think you're just trying to get a tune so you can have two of them, hahah!
