Been working my "84 for about a year now, progress has come with pain - proving the old adage. Just finished a parallel plumb and added an external VAC referenced fuel pressure regulator. Tuning comes next - an area that's all new ground for me. Hoping to get smart I just picked a book titled -...

Getting a reading of infinite resistance on my knock sensor ("84 Vette). My research is unclear on this. Anyone know for sure if this is an indication of a bad knock sensor?

My "84 has a vacuum issue which I'm having a difficult time resolving. Today I tried the cigar smoke test and found both the IACs leaking from the back where the motor is housed. Do I need to replace them or is that typical of a good IAC?

I inadvertentlty started my "84 with the number 2 piston spark plug out. I heard this very loud knocking. That normal? Ran for about 10 seconds and I shut it off. Plugs back in, ran it for a about a minute and it was hard to tell if there's still a knocking because the car is loud and could be...

Just installed a new heated O2 sensor. Issue is it pushes a flat 450 mv with the car ("84 Vette) running hot. No short in O2 ECM connection and I bench tested the O2 sensor it passed. Also bench tested the heater - applied some juice and got heat. On the car I doubled checked the hot wire to...

Looking for a shop or an individual in the Chicago area who can tune my "84. Has mods - heads, cam, headers, no cat... some others. In process of installing an EBL ECM from Dynamic EFI. More details on request. If anyone can recommend a source it would be greatly appreciated. I'm about 40...

Looking for tips, help, links, pictures... on how to mod the ECM connection to fit an EBL Flash ECM (on my "84 CFI). I know you can go the DCS HAM board route but I'm looking for alternatives like - installing pin connectors or modding the harness. This is the Dynamic EFI's EBL Flash...

With a later fuel pump and an adjustable fuel regulator you can jack your fuel pressure way beyond 15 psi - right? So, will the stock injectors flow more fuel? Anyone play with this? Need ECM mods? TB's are bored to 2", have Renegade installed, mod'd heads and cam.

Went cruising the wheel sites looking for 16" wheels for my "84 and found nothing. A bunch of 17's and BTW you gotta buy the adapters. I already bought new tires (16's). Am I like stuck with the stock wheels or is there something else out there? I like the 5 spoke mags - help! Thanks.

What happened to the Xfire Mine forum?:confused

Hi, all! I inherited an "84 in near basket case condition. So far it has a complete new brake system and a rebuilt trans. It's at a local shop getting a rebuilt crate (355) and other mods. We're keeping the CFI and going after the Renegade. Car has some sentimental value so it's a keeper...

Here's a thread that may interest some. It's my thread, probably should have started it here instead but I wasn't aware of this special forum at the time. Kind of lengthy - the meat starts on page 4. DigitalCorvettes.com - Times for a ~320 HP "84?
