I have not updated this thread in awhile. I wore myself down a little trying to get my car ready for the racing season.
I'm very optimistic about the direction my car is headed. The car set the 4th fastest time of the event, which was a huge surprise, considering that I had to hack together a tune & my suspension setup just to make it out to the race. My Hoosiers are also 3 years old, and barely even have grooves left.
Here are my BK7RE's. I'm going to run a plug one step colder, I have some iridium BKR8's on the way. Notice the color change at the ground strap. Thats optimal, but I need to play it on the safe side. Once I turn up the boost, it may be too hot of a plug.
4 port Mac Solenoid & 4 Chanell EGT module.
Here is how my waste gate is plumbed. In it's defualt state, it can run off the wastegate spring for safety, (in case the solenoid fails).
5.8 lb spring, 38mm Tial wastegate, Mac 4-port Solenoid. Here is one of my first test Datalog's of a 3rd gear pull with 45% duty cyclce.
I reach only 6.8psi & 3500 rpm & reach my target of 12lbs by 4500 rpm. Nothing to be proud of, just showing how un tuned my car was for the last race... I was using a open loop control strategy with a 3d map consisting of, RPM vs TPS.
I think I can optimize spool up in any one gear, but not for all gears with my open loop setup. I could ditch my soft wastegate spring setup to help reach my target quicker, and prevent the wastegate from cracking open, but I choose the 4 port solenoid soft spring setup for a reason. I want the ultimate throttle modulation which means I may need 5 lbs of boost at 6k+ rpm and part throttle. I'm going to work on a closed Loop control strategy that should optimize spool & transitional response. I wish my car was liscensed for the street. Tuining is a PITA!
Mocking up my new dash... It's my GalaxyS2 using an app called ShawdowDash connected via bluetooth to my MS3 ECU. It has GPS track mapping, and full datalogging capabilites. I'm going to order the 10hz external GPS module for the next race so I can take advantgae of the track mapping functions. It will be nice to overlay laps with my co-driver to compare driving styles. THe GPS sample rate on my Galaxy2 is super slow & basically worthless except for steady state MPH.
