Default lt1 24x convertion

iv'e just got my 24x opti-spark conversion kit from http://www.eficonnection.com and was wondering if anyone has worked with tunning the ls1 pcm to run in harmony with the original lt1 motor.

I'm going with Frost because he's close location wise to me plus once the car is up and running I'm going to take it to Frost for the final tuning.

Run in harmony with the LT1? That's what it's designed to do...it's pretty much set up for you from the get-go (minus some fine tuning).

The choice of grammar and sentence structure suggests trolling. Just sayin'.

As stated, plenty of folks have done this and had them tuned with HP Tuners. What specifically is the question?

One think i always wondered, is the LS1 pcm flash tuned like the lt1? Or can you make changes on the immediatly.
Im always worried about messing something up midflash and frying the thing.

Changes can be made on the go, IIRC.

The PCM is flash based just like the LT1 94-97 . You can get real time tuning with both EFI Live and HP tuners as add ons . You also do not have to reflash the whole program each time you make changes .
