G'day guys,
So I've made the switch back to direct port injection utilizing 140cc DP jets. I also used a 260cc jet post intercooler and a 140cc jet pre turbo. On the dyno, things did not go as planned as the car ran out of injector flow and also developed an inlet manifold leak. I did managed to collect some useful data though:
In the log below, the car was running 20psi boost without WMI. Cylinder EGTs were consistent and pretty much equal throughout the rev range.
In this log, the car was running 32psi boost with WMI. You will notice that cylinder 4 EGT falls to around 40 degrees lower than the rest soon after the WMI is activated.
I have a strong feeling that a lot more of the liquid from the post intercooler jet is making its way into cyl 4 than the other cylinders. I would really appreciate some feedback on what you guys think after taking a look at the logs. please note that in the logs, AN6 - Voltage 0-5V is reading the voltage output from the Aquamist flow sensor.
Cheers.
