tunning w/ evo 9 pistons

[92talontsibryce]

ok well i am currently rebuilding my 6 bolt and have decided to use evo 9 pistons. They were cheap, forged, and had a compression ratio of 8.8:1 . Well im almost ready to drop my motor in and some questions have poped in my head about tunning. Well the stock 1g rods have a compression ratio of 7.8:1 and my new pistons are 8.8:1. How do i tune for this and what all do i need? I have a safc and a logger but do i need something else? i cant afford link right now so thats out of the question. But could someone help me out here or point me in the right direction?

Thanks,
Bryce

Yes, you need something to tune timing with.
There's other cheaper options to get a full tuning solution, like DSMAP, MMCD(i think thats it), Ostrich, etc.

So would this mean my safc is useless and i need to upgrade to another source of tunning?

I didnt see it listed but a wideband will be nescessary aswell

So could i do something like dsmap w/ speed density?
