switching from one tune to another (91 oct to 93 oct?)

[DaveAN55]

Currently I'm running the 91 Oct tune which has been customized and fuel trims have been dialed in. I'm most likely going to try the Diablo tune next, which I am assuming is the 93 tune on my u7194 (v9r29). I run 93 all the time anyway.

1) when switching from one tune to another do you have to reset parameters as with installing a custom tune? Or can you just install the 93 without resetting anything?
2) will I lose all of my settings, ie, trims, fans, speed limits, etc? Should I write all of those down and apply them to the 93 tune when I install it?

I looked for this info on the forum but had a hard time finding it. Sorry if this has been talked about already. If so, can someone post a link?

Thanks a bunch!

1. Thats up to you, if you changed tire size or speed limiter, and want those changes to apply when you load the new tune, then do not reset them.
2. You only lose those settings if you restore the stock tune or if you reset parameters.

Thanks for the reply mikel. I would like to keep the settings the way they are but just move up to the 93 tune (Diablo tune) for the extra timing and spark (hp/torque).

So I don't have to send back my Diablo tune to you guys to have the speed limit fixed? I was under the impression that since you fixed the G8's speed limit issue in the 91 tune you would have to fix it for the Diablo/93 tune?

Did I get that incorrect?
