Vr v6 auto turbo

[OND150]

Hey guys, I have been trying to research until my eye balls hurt to avoid being that guy!.
My son and I are building a turbo Buick, while I am not new to this seen I’ve built both Buicks and turbo ls in my time, I am trying to wrap my brain around the computer setup what I would like to know is.
Nvram- do I plug memcal back into Nvram prior to tuning?.
Will the stock memcal be able to be read and erased/changed via Nvram?

Apologies if it’s been asked 10000 times and please just point me in the direction that has the info I’m chasing

Cheers

All the common info is here in the FAQ, also the green question mark at the top right of the forum menu bar is this page.

No you don't need to, the memcal only serves to pass through the netres which is used for limp mode and the knock filter.

So if you don't install it, you just loose the ability to run limp mode if the NVRAM become corrupt and you will have to disable the knock function in the tune which I recommend anyway since the factory knock filter is useless and only hinders tuning and creates confusion from it's false knock detection and lack of real knock detection. I would recommend knock headphones like the pros use, so you can actually listen to knock, some get fancy modules that can also log and graph completely independently from the ECU as well.


The entire tuning process in done in the NVRAM, the memcal does nothing other than what I already mentioned. Once you are happy with the tune, you will need to upgrade the chip on the memcal to a 256 or 512kbit EEPROM and burn your completed tune on to it, then move the memcal back to original. The NVRAM is not a permanent solution, it is vulnerable to data loss and corruption, so it's only a tool for real time tuning. And the original memcal with the chip replaced will become your final reliable "permanent" solution like factory, although it can also be reprogrammed as needed, just not real time/live.

I recommend the T48 chip programmer for not only doing your final memcal's EEPROM, but also as an emergency recovery for the NVRAM if or when it gets bricked from corruption.

Happy tuning!
