Thought this would be a fun thread.
What's your best 0-60mph time in your C3?
I managed to get mine into the mid 4s on a 93 degree day in June.
Data logging started when the TPS went to 100%. This is from an excel dump file from my laptop.
No load on the torque converter - it was a true dead...
I haven't posted about my 82 in a while.
This car has been in my family since the 1980s. It was my father's and he taught me how to drive... with it! I have so many memories of riding around with him in that car. When I was a teenager, he let me take it to a few school dances, on a few dates...
Thought I would share a walk around of my ‘82.

Yes, it’s a crossfire.
Well... sort of.
But not really.
There’s not much left of the OE system anymore actually.
But that’s okay. The car has been in my family for 30 years, so between my dad and I, we’ve tried to keep it looking...
Current list of mods on the 82...
OE TBI units bored out to 52mm running in parallel port fueling configuration
Renegade Intake (aftermarket cross ram)
90lb injectors
Aeromotive Variable Fuel Pressure Regulator (25psi at idle / 28psi at WOT)

I was 13 when my dad purchased the '82 Vette. It's been in my family continuously for 28 and a half years.
It was on my birthday and I'll never forget how excited he was and that he wanted me to come outside and see the car. We had spent about 2 years looking for Vettes and he finally found...
I purchased this wiring harness adapter so that I could upgrade to a heated O2 sensor... passing along if anyone wants or needs to do this conversion. :thumb
Access Denied
Overall, I am very impressed with it! Construction was great and has ample length for the accessory-on position lead wire...
I am going to wire in a three-wire heated O2 sensor.
But it's early... and I don't have my schematic in front of me. :)
I'd rather not go to the fuse box since this is under the car.
Thoughts?

After 80k+ miles... a 3.73 rear end... a higher HP motor... and 30+ years... the transmission needs my attention. :ugh
I've looked around for a decent local shop with little success. I haven't found anyone I really trust. So, I am going with an aftermarket rebuild from Monster Performance with...
VE stands for volumetric efficiency. Maximum VE follows right after peak torque... and the VE table is the base document to tell the ECM what to do for fueling. Everything else that happens is a modifier to that base document. Cold outside? Add to the VE table through multipliers. Still not the...
1982, 1984, and 1985 Vettes use the same heads. Spark tables are largely determined by the heads.
That's important to know because it seems the '82 and '85 Vettes did not have their BIN (calibration settings) for the spark tables saved or available.
1985 Corvette head castings numbers are...
First off, I am not anywhere near an authority on tuning. I'm no where near close! :thumb
That said... in the interest of the hobby, I share what little I know in the case someone else can apply it because there are no GM L83 BINs available to compare or start from.
For those of us who are...
If you plan to keep the crossfire looking stock and upping the performance, you've likely decided on porting the OE manifold or obtaining an X-ram or Renegade intake. You've probably also thought about a different ECM, injectors and throttle bodies too. Basically, you're thinking about how to...
Red spring- blue spring...
Old spring- new spring.
Dr Seuss... or setting a 700R4 governor? :chuckle
With the 2.87, I had the GM purple and a B&M orange spring and that gave me a 1-2 shift at 5,450rpm. When I upgraded to the 3.73, the 1-2 shift was probably over 5,800rpm - way too high...
I wish Year One would release a 17" version of the aluminum wheel. The Rally wheels in 17" are really nice, but a 17" aluminum would be great. I'm sure someone would run those on a Camaro too, I'd think it might be viable for Year One. But I guess the market is too thin for those. :(
Anyway, it...
30+ years on the 82's rear end was a good run.
It was time to get some work done in the rear with shocks, bushings, and the differential. The rear end was coming out and so it was a good time to clean up the somewhat noisy rear end and go to a 3.73 ratio. I had thought about a 3.55 at one...
I finally got around to taking the 82's interior apart for a thorough cleaning and restoration. This is at least the 5th car I have replaced carpet in over the last twenty years.
I left the dash, glove box, gauges, and center console alone- and basically pulled everything out from the kick...
:beer
Coming soon... custom 140 mph speedometer and custom tachometer with the correct redline for my '82s engine. Both have the '82 specific crossed flags.
The tach's red line is 5,500rpm- right where I shift from 1-2 at 5,450rpm. :upthumbs
I purchased a GM licensed restoration cable a few months ago.
When the car was warm, well... let's just say the cable's metal innards came out of the plastic outer shell and I had to pull the cable from the driver's side as best I could to get the passenger side to release. :ugh
I called up...
