Does the Trinity have the option to install the trinity and keep my custom dyno tune?

1998 WS6
Custom cam
Z06 heads, ported, polished heads, bench flowed
removed all EGR


If I have already installed the trinity and accidently installed the original factory tune, can I retrieve my previous custom dyno tune?

If there is no option to keep my custom tune, then the Diablo Sport Trinity was a big mistake! A $600 dyno tune is worth more than the Trinity.

I think you emailed us, but yes, as long as the PCM is not locked, the trinity will read out your existing tune and save it as the backup, and let you modify it using the modify stock tune option as desired.

Thanks

How do I determine if my PCM is locked and how do I lock/unlock it

if the trinity can't read your pcm or install a tune to it, then you'll get an error, meaning it's locked..

if it's locked, you'd need to have your tuner unlock it..

Thanks. Everyone.

When I attempted to install my Trinity, the first option was to install the original manufacturer's factory tune for my specific model of car. Without performing this process, there were no obvious way to skip this step and proceed with the installation. Am I overlooking a means to install the Trinity without over writing my current dyno tune with the original factory tune?

No, it will read the current tune out before it lets you write anything....

Thanks
