V1 Lokian's Extended Street Gob in Indiana - 10 LS # 251

[Lokian]

Well good and bad day... I got some powdercoating done and tested the colors I want. It is a 3 step procedure. Bad news... I done goof. Went to remove the dipstick and broke it off. Then to make matters worse... I used a pick to try and remove the rest of the tube and broke off the tip.. I have no idea where the tip is.

Bummer on the dipstick, but that powder turned out great! That matte purple metallic is almost exactly what my wrap looks like.

Just throwing it out there that I have a whole 100’ roll of it. It’s a discontinued color from Vvivid. Matte purple ghost metallic.

If it is in the oil pan pull the dipstick tube out and put a retrieval magnet in there.

Tried but the dipstick is down in there. Probably going to have to pull the oil pan :/

 

[Lokian]

So apparently acetone is bad for powder coating in between layers...

 

[Towerdog]

Kinda looks that way!

 

[Lokian]

For the engine harness. I'm deleting the ac wires, evap, Fan and can I also delete the second O2 sensor?

Any other wires not needed?

If you plan on boosting at some point you might want to keep the AC pressure sensor wires. You can reconfigure that input to data log a wideband in HP tuners and not have to buy the pro version.

I kept the fan wiring. One is used, one is not, but I figure if I ever need the second one for other coolers, it’s there.

 

[Lokian]

Do I need the old shift cables?
What about these items in the pics?

 

[Goblin Graber]

You need the bearing from the top piece

 

[Lokian]

You need the bearing from the top piece

already knocked it out per the video instructions

 

[Rttoys]

Nope. Don’t need the cables.

 

[Towerdog]

Nope. Don’t need the cables.

The kit comes w new shift cables?

 

[Lonny]

You will need the adjustable snap on ends of of the cables.

 

[Rttoys]

The kit comes w new shift cables?

Yes. They will be much longer. You can sell the old ones.

How does this work? I was planning to plug the wideband into a serial to USB adapter and then into the laptop. It would be great to eliminate that step and have everything pulled directly through the obd2 port.

The ECU in a Cobalt is already listening to the AC Pressure Sensor, and is able to send this sensor's voltage on the high speed GMLAN which is GMs early version of the CANBUS system.
HP Tuners VCM Scanner software can monitor AC Pressure Sensor Voltage via the GMLAN on the OBDII port.
If you hook that AC sensor wire up to a wideband O2 sensor, then the voltage can be used by the software. I would check the voltage range of the original AC sensor and be sure that wideband sensor is in the same voltage range. Hopefully they are both 0-5v sensors.

VCM Scanner is used to gather log files while your engine is running.
This data is then used to modify the tables in your ECU, by using VCM Editor.
You could write a user defined math parameter named "wideband" that uses the voltage from the AC Pressure Sensor, and that can become part of your graphs.

This video gives you a good rundown of the process.
