Get a timing light, a cheap one is sufficient. It makes a world of difference when you get the timing spot on the specification.I spent a couple of hours once getting the last half a degree correct....now car runs just like new, incredibly smooth. Plus now you will have a tool that you can easily test spark with.
It is near impossible to pass emissions with a KLZE engine. I didn't know AZ was very stringent yet on emissions tests.
The car will run fine and noticeably faster with a KLZE engine....no need to swap ECM.....vris shift points will be different, so near impossible to get those exact or alter them.
