Hey guys and gals. Just got back into tuning my 89 IROC and have a quick question.

Does the Spark Advance table in TunerPro show the TOTAL advance including the 6' distributor setting or just the amount added?

I just installed some PC 190 heads, RRockers and a few other goodies and need to make some changes. It's been so long since my last tune I feel almost like I'm starting over. In a way I am since my kids "lost" my old laptop so I am having to re-establih my starting bins and everything. Good thing I was able to re-read my current chips! Been going back over the all the stickies and other stuff on this and other sites. Any input will be appreciated.

BTW I just realize Grumpy isn't with us anymore. Love or hate him I gotta give him props. He never was shy to express his opinion and persepctive. Damn that man had a lot of experiance and knowlege. Wonder where all those notes went... At least he shared soooo much here.

 

what you see is what you get. The reference for the ecm is your base timing.

 

Thanks. I think I thought about it too much.
