I just ordered a tune tonight......I cant wait!

 

What rwhp gains have been seen with one of Ion's tunes? Also, mind explaining how to install a new "tune?"

I'm not down on this OBD1 lingo

BTW--'94 LT1 M6

 

You just send Ion your entire PCM unit(takes about 2 minutes to remove it from your car)

He sends it back, programmed. You reinstall it.

Couldn't be easier.

If you want to install the tune yourself, you need a laptop and a data cable to connect to the OBD connector under the dash. You also need a program that allows you to upload the new tune, but I'm not sure what programs you need. (I'm pretty sure LT1 edit will do it.)

Oh so you can't use your car while the PCM is being worked? Dang. See I'm used to this Speed Density thing (like with my old 3rd gen) where you can get a chip burnt, and just replace yours.

Thanks Dan. Looks like it'll be a while before I can get mine tuned then...

 

You can buy an extra PCM from Ion with the new tune on it. It costs more, but you'll never have to worry about downtime.

Yeah, how much does one cost though? Geuss I'll hit his site...

 

Or if you have a laptop and cable you can order his email package and upload it yourself, thats what I do and it works out great
