Northern Va Tuner

[NASABlue]

Have EFI live and LC-1 wideband installed on a 97 head cam corvette and was looking for someone to properly tune my car. I have tried a popular option in va beach, but was very disapointed with the incomplete job and poor results.

Any help is appreciated,

Thanks

Ray I am sure some vendors can help you out..but why not learn yourself?

A majority of us started with little acquired knowledge..only qualifications needed are interest and persistence.

Here are a few 'reads' to get you going. I think I even throw in a 'free' Tune on one of them...

Good luck either way..

Hi Ray, the method Shawn has developed is pretty dang easy to pick up. Im tuning an 02 5.3L Suburban with just the narrowband O2 sensors and its already picking up a little power and mpg using the Calc.VE method. The new Calc.VET is even better, but I didnt want to put a WBO2 on this truck. If you have a WBO2, EFILive V1/V2, you can get the VE dialed in pretty quickly. Spark should really be done on a load bearing dyno, especially with your mods.

Have you considered a 99-02 PCM swap for more tables and tuning options (COS, etc)? One of the benefits of the 97-98 LS1 PCMs is they are free to tune with EFILive (no PCM licenses needed, all V1/V2s have the 97-98 LS1A stream enabled), but 99-02 PCMs have better table resolution and COS availability.

I would love to learn, when I really had the time to try a few years ago when I got it, I just couldn't get all the pieces together to be successful. from August to december of 09, the car sat waiting to be tuned and it just wasn't happening. I wanted to get back to track events and become a hpde instructor, get a racing liscense and have fun with the car. I got someone to tune it, but it isn't right. It still makes me mad the effort I went through to get it there and they wouldn't let me witness the tune and after 4 days so they could "dial in the cold starts", they still never tuned the maf, the low end drivability sucks, and the car doesn't behave as well in certian wheather.

I'll take a look at the supplimental write ups and see what I can remember from the last try, hopefully it connetcs the dots.

About the computer, I've looked at swapping out to a better unit, I know there are significant advantages to upgrades, but I'm only ever going to run N/A and I would really like to see a gilmmer of success in tunign the existing before "splicing in faith"... call me a doubting Thomas which is much better than Judas... Easter appropriate referance

I'm going to have to brush up on my acronyms, COS and the like. I'm not worried about burning credits, I was actually thinking of trying another format which forces credits, so certainly the $100 or whatever in credits it would "cost" wouldn't hold me back.

I just want someone to be honest about tuning my car and maybe work with me so I can have a tune timed for 93 and 98 or 100 octane. When the time comes, I'll need to do it for reducing the cam as well, so developing a good relationship with someone is important, but I would certainly like to learn to do more myself as well. Ultimately, I don't want to loose track time messing around with a stupid lap top perched on my passenger seat blasting my race exhaust through police/sherrif/trooper/fbi/cia/tsa/dhs/ss infested Northern Virginia... for what to go to court because I was tuning my "race car". So thats the reason for leaning towards paying someone for their skills directly than have it taken out of my pocket in some other way and be left no better off.

EFI Live Doesn't use "credits" the way HP Tuner does. Once you have "licensed" a PCM all
features of EFI Live are free. If you changed PCMs you need to use another one.
It's kinda sad that these stories pop up all over the place. Post your tune file.

here's the tune

Lot of truth in what you are saying. Unfortunately I have learned no one loves your car better than yourself..I.E. the best Tuner will always be yourself.

Your set-up is not that far from mine. So far no tickets, wrecks, or nervous breakdowns..

My best advice for a D.I.Y. tuner is to start off with closed-loop (using your NB's). Easy, takes an afternoon to tune if that..add a Wideband and its done..

Good luck either way...

Got the wideband, bought and installed the whole thing when I rebuilt the car... I got a wheel bearing and cracked rotor to change out, yep I was having fun last weekend

I've seen your posts around and appreciate your time.

THanks for the support.

WOW this file has the "classic" mistakes that I learned about at EFI University.

Do you have a dyno sheet ? Do you know what RPM peak torque is ?

looks like 4800 rpm
