I had MTI tune my PCM about two months ago or so. I was one of their early LS1 edit tunes. They did a great job on the PCM, but, I think I might want to further raise the shift points (It’s shifting at about 6200 now) to about 6400 for the B1 cam that’s going in. I think I might also want to drop the idle down a tad (50 or 100 rpm) after the cam install if the idle is strong enough.

Here’s the deal. I don’t really want to go through send the PCM to Texas again, and I’ve heard that a local tuner (Zap PCM) also has the unlimited user LS1 Edit programming now. I’m wondering if I can have Zap make these minor changes with their LS1 edit, or do I have to send the puter back to MTI? MTI already did all the in-depth stuff like the B1 specific tuning and all, the only thing I might want to change is shift point and idle rpm. I would e-mail Zap, but their website is down and I don’t know how else to contact them.

So what do you guys think? Can more than one LS1 edit shop mess with your PCM and not have to start over?

 

Of course. Any shop can touch that pcm. Why would ls1 edit care?

That seems simple! I guess I was just concerned that it might be difficult for more than one shop to mess with the same PCM without starting from scratch. I don’t totally understand what is involved in performing a custom tune (programming wise), hence my asking this question.

Thanks for the reply <img src="gr_stretch.gif" border="0">

Anyone else have an opinion or experience in this area?

 

ZAP is out of business, Brian is going it solo now.

Here's his contact info:

And he shouldn't have a problem reading out the program that MTI did for you, and then making adjustments.
