I have heard mixed answers about how it all hooks up when I was researching into an LS swap. I thought that they mentioned that the ABS was going to need new reluctor rings and you might have to hook up something so FX3 can get a VSS reading since it is speed dependent.

Also kinda why I am debating what to do. If something happened to my C4 today, I'd definitely take the money towards a C6 since tuning will be easier. You are right that the C4 is a dead platform, hence the issues.

 

I spent about $100 [for the Burn2 and the G2 memory adapter] @ Moates. Probably another $50 for an ALDL cable and chips. I went to the dyno once. 4-5 pulls for $50...but I think you'd spend that no matter what you used for tuning!

I started with the stock tune (found on TunerPro &/or Moates), then modified from there. No mail order costs. In fact, my contact with mail order guys led to major frustration! (I'm glad I didn't use them.) Oh yeah, TunerPro has an optional $30 donation....which is worth it if it works on your ECM.

A wideband would have been simplified matters though I opted to let BLMs and INT guide me. I'll admit the learning curve was substantial but I'm in I.T. Tuning is manipulation of simple parameters....which basically meant memorization. Compared to computer programming, it's simple. For me, it was enjoyable...and "relief" after spending over $15k on the engine, external, and interior rehab. I just didn't want to spend another DIME! LOL

Full disclosure: I had a couple of guys that were particularly helpful in getting me started (from this forum and TGO). Plus, the learning curve for major engine modification was substantial anyway. There's a lot involved to piston, cam, rod, intake, header, and other part selection (combination). My interest in engine modification was as much about learning (hobby) as anything. To me, if you're going to learn what the parts accomplish, why not learn how they are "managed"?

 

i AGREE, I love to learn and do these things myself I have an ostrich and love it My main problem is not knowing what everything means in the bin while using tuner pro rt i try looking them up on webb, but most of time it doesnt seem to help me I have stock bin, arap bin and my current bin which i have changed minor things in it

i was just hoping there was a better and easier system to connect to my engine which would make tuning a whole lot easier

 

Is that because you don't understand the results you find/read...or because you have a hard time finding ANY explanation?

One of these days, I suppose we could create a thread with tuning parms and their purpose.

 

To make a simple answer to your question. You can change many things such as intake, exhaust and even heads. As a general answer to those changes the stock computer will compensate for these changes. Once you change the cam from stock you will need a tune.

Can those changes such as intake, exhaust an heads benefit from a new tune...yes you can dial in the tune to take advantage of these changes. But it is not always necessary.

What you need to consider is to do some research on the combinations of changes and parts that have SUCCESSFULLY been applied in the past. It is the COMBINATION that is matched up that makes the upgrade a success. You really have to approach your build as a total package rather that adding this and that.

I am not an expert at tuning. I would rather pay someone who is and knows what they are doing to dial in my tune. That is why I drove over 800 miles to take my 85 to someone that is qualified and knows Corvettes and how to properly tune them.

 

I can't be sure about MAF but in my 91 F-body, at some points it seemed to run better but there were hesitation points that we couldn't fix without bringing it to Decatur for John to do whatever he did. After which, life was fantastic. I'd go as far as to say that it didn't drive well till it was fixed right in the program. Who did the job for you?
