So today I went to the garage to try and start the car in 20 degree weather. As soon as I plug my laptop in, I notice the VTPS is not working properly. The tps % and DC would not change at all when pushing on the accelerator and the values would slowly rise over time... what can cause this? It was working properly last week.
Also the lowest the coolant temperature goes is around 55 degrees, even though my garage is way colder than that? Is the sensor bad?
Any help is appreciated

I bought another vtps sensor from ebay for $30. We'll see if it works. I soldered all the connections and used heat shrink so I doubt it is a short on the wires.
I suppose I need to recalibrate my coolant sensor as well.

New wheels and tires!
A few more updates, the local Bridgestone supplier was selling old stock new Bridgestones. I really wanted 205s but he only had 2 left, so I went ahead and bought 4 195/50-15 RE11s for $200, yes, $200.
I had plans to sell my current 15x6.5 Konig Heliums and get a set of 15x9 6uls. Well, since I have 195 tires I opted for a set of 15x8 Konig Dial in. I will use 205/225 after the Re11s wear out, they are a little stretched but not bad for a 195 on a 8" wide wheel.
I also bought a set of toyota coils from ebay for $50 and the connectors at the local junkyard and made my own COP harness. Wrapped it with sleeving from Mcmaster and used their high temp self fusing silicone tape.
I sandblasted the valve cover today and will have HHammerly weld aluminum standoffs to bolt the coils. I think it looks cleaner and is cheaper than buying the hold down bracket for the coils.

If I made the harness again I would have the COPS pointing the other way and tuck the harness next to the fuel rail. Oh well, I think it looks decent and the entire thing cost me under $100

Here is a log of a 4th gear pull. Im not sure why the boost graph oscillates so much when it reaches around 7psi. Maybe is the wastegate spring moving up and down. Its a 5.8psi spring maybe I need a 10psi spring

Thanks! I installed a sparco sprint seat and will dyno tune it March 13th. I will post pics of the seat brackets. I also installed a catch can. I'll upload pics tonight.
