This is a DSM tuning guide that me and kyle (kpt4321) put together.

DSM Tuning Guide 2.1 UPDATED!

On the first page is a fuel tuning, second page an airflow calculation sheet, and Tuning Tip sheet as well.

This guide is meant for the beginner and intermediate tuners, to help you get started. Please, give feedback or requests to [email protected] and ill consider any changes.

It is in excel format, I am working on a palm compatible spreadsheet as well. For now, this will do well for those tuning at home or in the car with a laptop. Please Enjoy!

Bump for a great tuning guide.

Right click and save as guys, so you don't have to keep pulling it from the server.

Very nice!!

I think I found a typo in one of the formula's for airflow calculation's. Shouldn't pr = (A4+B4+14.7)/14.7? In your's it's (A4+B4+14.7/14).

if you scroll to the bottom of that sheet, under PR it explains why it is at 14 instead of 14.7

basically we assuming .7psi of pressure loss through the air filter.

hopefully that answers your question.

Actually I was refering to the placement of the ()'s.

Good catch man, I can't believe I missed that. )

It'll be fixed in short order.

The file has been updated =). I am also currently working on a how-to if you are confused on how to use it.
