I didn't work on the car for the last two weeks after burning myself out on the wiring. Got back on it this weekend, to see if i could finish up the chassis harness integration and test the push button start.
Well this is my first turbo car so was looking over logs and thinking about the wastegate setup and realized, I was thinking about how it worked all wrong! I thought it applied pressure to the bottom with wastegate pressure reference, not bleed it off! With that thought process and realizing 0% duty cycle meant full MAP got to the bottom of the gate, made me realize I had some significant vacuum leaks (no plugs in the other 2 bottom ports).
The ports that got plugged.
While the gates were out, and realizing I just dont have enough pump to support my E85 dreams, I pulled the springs and installed an 8.75psi spring (was 10.25psi prior).
One thing I learned that was VERY nice, is that it takes about 1hr to pull both gates, swap springs, and put them back on. Could probably be done faster, since this time included putting the plugs in the bottom ports.
With the wiring tidied up as best as it can be in the dash, and the push button wired, i decided to put in the dash to see how it looks.
It looks badass...
Sadly I see that I need to shim the steering column down just a bit more. Still want to figure out a way to recess the racepak into the dash. Also found that i'm missing the tabs for the fasteners for the dash, so it's just sitting in for now to test.
And it works. The illuminated button is the push button start. I do plan to blacken that AC display surround, just haven't done it yet.
The buttons on the right control: Lights (worked with racepak dim feature, i tested), Dome light, Holley input, Line Lock.
The buttons beside the racepak are the control functions.
Some issues came about with this work.
#1 - The damn heater hose still leaks in the car. Going to have to pull it again, and try to re-install and solve that before it all comes back out to replace the hose.
#2 - The start button was a bitch. It defeated me today, until i went in, sat on the PC and grabbed a beer to research. I found that my instructions had apparently been updated (online) and it was going into a mode that wasn't clearly explained in the instructions. I got it sorted and the push button works no issues.
#3 - The racepak wasn't displaying with the car on. I hadn't tried to program it prior to starting it so hopefully that's the issue. Well i went to use the USB as directed to program the unit...They didn't send me the latest software so I cant program the IQ3s (street dash). Part of being in the first set of shipments I guess. I'll call tomorrow.
