If it helps I made vroom vroom noises in my head...

How soon until start up?

[wheee!]

Probably a while. All the wiring harness is still out and needing splicing with the Haltech, the push button ignition system, the coolant system isn’t started yet... probably next year still. The body work and paint is still next.

Haha!!         It always does, my friend!!

[wheee!]

Nice car club meeting last night! Good to see all the cars out between these last 30 days of rain...

[wheee!]

Ordered a few more parts. Cold air intake piping and filter, intake air temp sensor, fuel pressure sensor, throttle position sensor adapter plate, t-bolt clamps and a bunch of miscellaneous necessities. So many “small” things still needed.

[wheee!]

Received the intake air temp sensor for the Haltech harness along with a Bosch style fuel injector wiring kit that I couldn’t pass up. $25 basically for a nice soft rubber 6 connector kit! The IAT was only $35 too so not too bad!

The Haltech uses the following sensors:
Idle Air Controller valve
Water temp sensor
Intake Air Temp sensor
Oil pressure sensor
Wideband O2 sensor
Crank Angle Sensor
MAP sensor

I’m pretty sure the control I’m going to have over literally everything else will give me better performance if not a slight amount of unmetered air or blowby.

Don't forget Throttle position sensor.  You need the kind that gives continuously variable voltage over the throttle position rotation range, not the stock on/off style.

[wheee!]

Got it already! It’s a GM version and is designed for the zcardepot adapter plate that is on its way to me now.

Decided to order a set of high impedance 11mm injectors for the car. The factory Cressida injectors are low impedance and the ones I have ordered will work better with the Haltech system. Same 300cc size which should be more than enough for the stroker.

[Zed Head]

What did you get?  Just curious.  Lots of 11mm options out there.

[wheee!]

I actually found them on eBay. They are flow tested and re-manufactured and the price was too good to pass up.

I emailed the seller and got a good response and I am hoping that this will make the Haltech system a little happier. I have heard that the high impedance injectors perform better with the newer ECU's and the low impedance ones I rebuilt myself can always be installed if I am unhappy with these ones.
