Hello Dsmtuners; I've been hiding in the woodwork for some time now and decided to finally participate in the community. Myself and a few friends have DSM's, and I've kind of been delegated to learn how to tune them. I'm fine with that, as I'm always on the site anyway and love learning about these cars, but I need some help to get started to prevent problems. I.E. blowing the car up..
Here's my question: My friend's car is logging 92% duty cycle on his 660cc injectors at 31.4 lb/min (16.8 psi) on his GReddy 18G. To me, that sounds a little bit high for that amount of airflow. The AFR is a solid 11.8/1 at WOT.
I'm not too familiar with how timing works, so if anyone would care to explain it to me in this specific log, that would be great. A lot of the problem I face is finding threads with exact setups of a car. Sure the theories behind all cars are the same, but they don't all behave the same way with how unique our builds are, so please don't flame me for asking how timing works in this log.
According to this thread:http://www.dsmtuners.com/forums/articles-tuning-ecu/366003-injector-fuel-pump-supported-airflow.html
660cc injectors should do the following: "80% IDC will support 37.90lbs/min"
Any advise is appreciated.
