I'm going to build on Hib's post with some of my experiences. First of all, I'm not a shop... or a professional tuner... or anything else. I am just a regular guy and cars are a passion and a pastime. I purchased a Renegade because it was the only intake on the market that might be up to the...

Your point about the mixture getting weaker and leaner is an important one. The ECM and stock calibration are not going to meet the demands of a a larger cam and better heads. For one, the spark table for smog era iron heads is not the right one for aluminum heads. The VE tables would also be...

Like any part, it might need some massaging here and there. I have a Renegade and it's been a great intake aside form a few small details here and there. Here are some of my thoughts... - Plenum Lid: I purchased a huge sheet of gasket material and I made my own gasket for the plenum lid. I...

Incidentally... I have Bill's TBs on my Vette! :thumb Bill- this was a great write up on how to do this. I frequently use a link to this page as a reference for how to balance TBs.

It can serve as a good foundation for future mods... by itself, it should run a little better at higher RPMs with the Renegade. If you bump the fuel pressure up 1-2lbs, that will help too. That will make the car run a little richer at WOT (where you want it to be richer because you are flowing...

Headers will help a lot! Don't worry about the heads and cam right now. Just have fun with it. Even the mighty oak tree starts out as an acorn. ;) Sent from my iPhone using Tapatalk

Yeah, I don't know what specs are for that engine's camshaft. It's a universal fit engine but they don't say what the cam is. If I had to guess, it's the same cam used in the 195 hp (up to 260 hp) GM engine that you can buy over-the-counter. The heads are going to be your typical smog era...

My sense is that the fuel pump relay has gone out. Sent from my iPhone using Tapatalk

Do you know which crate motor from GM they put in? Sent from my iPhone using Tapatalk

I agree with Don about finding an old school shop. For example, I had an old school hotrod shop set up the rear gears on my Vette. Labor rates were great and like Don said, they could do the work in their sleep! Sent from my iPhone using Tapatalk

I have an EBL Flash ECM from Dynamic EFI. EBL_Flash Tuning? The short of it... lots of trial and error, reading, and asking questions from people that know how to tune GM TBI. A good rebuild is rooted in the parts and labor. Labor costs vary as do the costs of parts. You would likely spend...

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...

Hi! Well, any crate that does not have the right cam to work with the crossfire will likely require the ECM to be tuned. If you want to go with a crate motor, the GM 260hp motor is a good base- but you'll need a different cam. The cam with that motor is too small. I would recommend COMP Cams...

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...

You should be able to remove the AIR pump, hoses, and associated parts easily with no impact to the car. However... if you want to run side pipes... YOU WILL NEED TO HAVE AN O2 SENSOR BUNG WELDED INTO THE EXHAUST PIPE. The ECM will throw a code without the O2 sensor. The O2 sensor is critical...

Here's a comparison graph between where I started in May 2014 and August 2016. I've since tweaked the tune and replaced the worn out plugs and wires. As a reminder, the car lost its OE camshaft a decade or more ago when a lobe on the cam wore out. So, I never had the chance to datalog it with...

The factory cam is kinda small- but it works great with the small port OE intake for a 200hp/285lbs-ft tq motor. GM took a crossram intake which excels at 3k rpm and above and "optimized" it to create low end torque and live quietly at low rpm. So, to do that... GM narrowed the ports on the...

Welcome to the :CAC The crossfire gets a bad rap because people don't know how to work on them AND they don't know why certain things were engineered the way they were. The cars themselves are good- it's the intake, fuel delivery system, ECM, cam, and heads that aren't performance oriented...
