TR224/114/112 tuning question After doing extensive research with the help of the wonderful people of this site, I've got my lists of mods narrowed down pretty much. Still deciding between the TR224/224 114 lsa .563/.563 or the TR224/224 112lsa .563/.563. Anyhow, my question is this - I was looking at handheld tuners, and ran across the Crane Powermax tuner that has preprogrammed setting for bigger cams. The #3 setting on the tuner claims to be proper programming for a camshaft of 224/224 114lsa .551/.551. The cams I'm looking at are in this range, with the 224/14 being closer. Would this be an effective tuning method? Would it work just as well with the 224/12? I am basically a parts changer, and not a diag tech or tuner, so I am looking for some opinions. I will also being doing the usual mods along with - long tubes, ls6 intake, valve springs, cat back, 12 bolt - If that info is needed.

My opinion is that you just have to bite the bullet, get the scanning and tuning software, tune it yourself, or have someone tune it for you. There are simply too many variables for a canned tune to take into consideration. Heck, you could use the money from the handheld, and apply it toward a correct tune. JMHO.

If you really want to go the canned tune route then I would buy the Vinci cam and Vinci programmer (which are both made by Crane to Vinci's params). Then the tune is actually gear specifically for that cam. That WON'T be quite as good as a custom tune since each car varies some, but it will put you right in the ballpark.

Get HP Tuners and start reading and studying threads. There are some really knowledgable people on this site that are willing to help. That's what I am doing. In the long run you'll be better off. Just my opinion.

How's yours for emissions? Did you have any tuning concerns?
I tuned my car yesterday and it was pretty easy. My LTFTS were still slightly negative with the new cam, so I didn't have to mess with that; I made a tiny adjustment to the pe vs rpm table. The only major tuning the new cam needed was IDLE. I raised the idle, 850-875A/C, adjusted the Main VE 400, 800, and 1200rpms (x70%, x80%, and x90%). I had added a couple of degrees of timing up to 1000rpms in the hi-octane table, but went back to the stock setting because it idled better without the extra timing. My tuning issues were so easy because I had done a lot of tuning before the new cam was installed. I was surprised that the new cam hadn't altered my fueling very much.

when you take your car to get a tune at a performance shop....what software do they use? hptuners? What is the best way to learn how to tune? I have a laptop with autotap and still am not very good with that.

I don't know much about emissions, but maybe some others can chime in if you could pass with the 112. If you could get by with it, I would do it. You won't have any drivability problems with a tuned 224 cam.

I went through the mental 112/114 debate, and after installing the 112, I know I would be very disappointed if I had gone with the 114. Heck, I'm thinking about what I can do next to make my ride even nastier.

Thanks Vegasman, 112, just a thought, 112, I don't know if Illinois, 112, is anything like Mass, 112, but the place I go for my inspection, 112, the gararge owner has a ZO6, 112, and the mechanics, 112, are total motorheads, 112, so basically I've always gotten a free pass, 112, so my point is, 112, you could figure-out a way to make a 112 legal. I say get the 112 and work on improving your odds of being legal later, 112. Tuning, pocket greasing, cool mechanics, whatever it takes, 112. 
Good luck!!!
