MAT = Manifold Air Temperature sensor - it's under the plenum.
...tells ECM what temp intake air is so it can control the EGR (on an 89 - on later models it's also used to control other things..)
My EGR is deleted, so I don't need the MAT sensor. With the resistor in place, the temp is now 'fixed'.
I installed my new headliner with the C4 logo today. This should help me to lower my times. I sure wish there was a carbon fiber replacement roof panel. I sure could save a bunch of weight.
I installed a new Power Acoustics stereo unit in my 84 today. The car was originally a non-Bose unit so it was a little less complicated. The unit plays CDs and DVDs as well as AM/FM and also has Bluetooth for streaming music and phone operation.
The music streaming is OK but depending on location tends to skip a little. The wireless phone operation seems to be just fine. It works for me just fine. For the price I paid it is a great improvement over the after market unit that was in the car when I purchased. It cost me less than $100.00 shipped to my door. It has a nice little LCD screen which is fairly easy to navigate and I think looks great installed in the car. Here are a couple of pics of the installation.
It was hard to get a angle that the LCD would show in the picture
I would highly recommend this radio to anyone wanting a inexpensive unit that has a lot of features.
It also has USB port, SD card slot and Aux in port.
Took the vette for a nice long scenic drive in the canyons while doing an open loop VE learn with the wide band O2.
I took some video but it's to long for YouTube by 5 minutes.
On the way home i took the freeway, ended up playing along with a pair or superbikes.
Tons of fun, and i felt totally comfortable at my undisclosed speed.
hey really like The way you opened up the bumper is it a kit or your own Doing ! I have seen a kit very Similar buy like $450. ! If you put together the parts would you be kind enough to share your part sources or Manufacturer of the kit ! 👍🏻
real nice job !
Just finished my 4th optispark replacement in 1 1/2 years . (2 MSD units , the first lasted 9 months for roughly 8k miles and the 2nd never made it a mile. Did an LTCC Conversion and skimped by with a cheap World Power Select opti that lasted 4k miles, and just installed a petris enterprise opti) Hopefully I'll have better luck this time. BTW all of my opti failures was either just a low res failure, or I lost both at the same time. The amazing thing is that I never had to call a tow truck!!! LMAO
Painted the air cleaner cover to match the new valve covers color, actually I do not like this color because it is for the 85 and newer model cars but I have not found a supplier with the gray color like the 84 cars but that is life, I still have to take the car for a drive after the Renegade installation and the emissions junk removal, if it all works right I will be driving it along Route 66 from the begining in Chicago to California then home to Colorado

Installed new upper and lower intake gaskets and valve cover gaskets then took it to a car show on Saturday. It was about a 250 mile round trip and the car ran great!
Finished cleaning the back of all my wheels. Hopefully will put them on tomorrow. Before and after pic. Not perfect, but a big improvement, I'm my opinion.
