Comments on CR Calculator for Android

★★★★★ Great app only one problem It won't let put in a negative number for piston dome. Fix that and it is a five star!

★★★★★ Include more F series tech Please update with more sohc F series like the F18 and sohc F20 stroke, rods, pistons etc. and the option to use USDM and JDM spec K20 pistons in F series would be nice.

★★★★★ It made me blow my motor! No not really. I like it and use quite often. Works well, and makes for easy showing to customers what to put in their engines.

★★☆☆☆ Incorrect information It claims a stock ls is 9.6:1? Ha ha ha couldn't be more wrong. Maybe with a hotter piston and some decking/milling. It contradicts information given in one of his other apps. Fix it or take it off the market please

★★☆☆☆ Hmm First use, changed a gasget thickness on a b series... Software quit.

★★☆☆☆ Needs fix Cannot manually make a negative dome volume for the pistons. This throws the compression way off. Will rate higher once fixed. EVO.
