I'd like to take a look at a tune for a 230/236 tune.

I have a 233/239 cam and am tring to see where that would fall compared to the tune I have for a 306.

The 306 tune seem a little off to me.
In the 306 tune the only changes made were to the spark tables.
I thought it was odd that there weren't any changes to the MAF tables.

 

I run a 260/260 solid roller with stock MAF tables

 

Good enough proof for me...

I'm looking over another tune I found for a 232/242 on a 114 and this tune shows 55 degrees in the main spark advance at a MAP of 40 between 1600-3600...that seems high to me.

Any opinions?

 

That does seem a littel high to me as well. I run inbetween 40-45 degrees of timing in any rpm range under 3000. I have heard some motors ( not limited to LT1's or LS1's) love alot of timing. IT all depends on the setup.

I run 53* advance between 1600-2400 below about 40kpa, its normal, stock cam there has 40*, so a big cam like that would like 54 if not more advance & it won't hurt it since the cam is not as efficient at low RPM's & at that MAP you always have lots of timing, add a big cam & you can get away with lots of timing almost anywhere down low, I don't think my graph goes below 22* advance anywhere, not even 800rpm 100kpa map, its fine, I tuned her but seeing where it would ping, with minimum timing of 30* & full map at 1000rpm I started hearing marbels which is pinging, so I went back to my good timing of min 22*, & kept on scanning with datamaster, whenever I would see the KR just blink a bit on the count, I would go to the graph & remove 2* to be super safe.
