Noob questions...

I am pretty new to ECU tuning. I just finished fixing everything I can think of mechanically on the engine, so I believe I am ready to tune the puter. I searched, and could not find good answers for this stuff...


My questions...

What is the advantages/disadvantages of going to a dyno tuner vs using a tuner program?

I have a external wastegate, larger injectors and larger throttle body. Is there anything else I would need to turn up the boost a little?

I think the scan tool will clear the codes, my Diacom would clear them, I don't think I have ever had to clear them with Tunerpro. At the very least you can just pull the ECM fuse (or disconnect the battery) and they ECM will lose its codes. The old ECM are not like the ODBII were the ECM stores the codes and a scan tool is require to reset the codes.

The search in this websites (and most like it), frankly sucks.

I always use Google and use "Site:www.syty.net <terms>" Waaay better.

-P

Dave's right... clearing codes is a SyTy 101 kinda thing....

Dude: If you don't know how to clear the codes in a SyTy, you are in need of one hell of a lot more than "simple little answers". And, they are NOT "simple little answers". They take hours and hours to write. And there are Hundreds of them. And most importantly, the answers ARE already available. This isn't anything new to the tuning gurus here. But it appears they are weary of typing. I seldom see these "simple little answers" get posted any longer.

There is TONS of tuning information on this, and many, many other sites. Refine your search methods. You're gonna need them. :)

I already know that I'm a newb that's that's why the thread is titled "newb questions". I would appreciate it if you would just answer the questions instead of telling me how little I know. If you don't know the answer then you don't need to post.

Do the tuning programs for labtops, check engine codes and clear them? (I don't want to just assume that they do).

Is there any reason for me to buy a scan tool if I have one of these programs?

What is the advantages/disadvantages of going to a Dyno tuner?

Simple answers:

1) Clear OBD1 codes by starving the ECM of power for about 1 min (disconnect battery or pull ECM fuse).
2) Depends on what you need a scanner for. Realtime data reading for the vehicles supported by the "tuning programs"? Just get the "tuning program". Want to scan a multitude of OBD1 vehicles? A scanner may prove more flexible.
3) Tough question to answer. For some, there are no disadvantages, save cost. For others, there are no advantages, save safety.
4) You technically don't need anything but 2 fingers to run higher boost on a SyTy. To do it safely? At least have a 3 bar MAP, a 3 bar chip/tune, an aftermarket boost gauge, a healthy fuel pump, and preferably an AFPR. WG, TB, and injectors are not required for higher boost levels.

I ran the codes today and nothing came up (code 12). The next step is to either get a tuner program or go to a local tuner.

Actually, I figured out how little you know, and tried to enlighten you as to how to get the answers you need, because I've been around here for 15 years, and I have a feeling you're going to be disappointed if you think the peeps here are going to "teach you to tune" because it "so simple".
I DO know the answer, and I gave it to you.

Good Night, and Good Luck.

I'm glad to help, but the fact remains that Dave and others are right.....searching on this site will go A LONG WAY. You have to consider that we're discussing nearly 21 year old technology, so most of what you need to know (esp. if they're simple questions) will be available on the site already. In fact, for clearing codes, it took 2 seconds for me to find multiple threads explaining how to do so:

http://www.syty.net/forums/showthread.php?t=48732

Search, research, and withhold questions until you've determined that you cannot find the answer you seek or the question hasn't been asked before. Doing so will result in a smoother, more accepting, and more informative experience here on syty.net.

Just wanted to apologize for being kind of a dick, but I wasn't asking "how to tune". And you were just telling me I don't know anything. You were kind of assuming things based on the first 2 questions (which are now deleted), maybe I should have rephrased them.

I know there is plenty of info on tuning in these forums. I was trying to get some info so I could determine whether I should attempt tuning myself or go to a dyno tuner and if there was anything I was missing before taking this on. I did search and read but would like more of a straight answer from some of the more experienced people on here.

Sorry for the confusion.

Asking about pros/cons of dyno tuning w/o specifying who the tuner is, if they've ever tuned a SyTy before, or what you intend to get out of the tuning session, is like me asking, "So, how about sex? Any good?" Well, it depends on who you're with, if they've done it before, and what exactly you're trying to achieve. Dyno tuning can be a great thing IF the shop knows how to tune a SyTy (I'd be interested in their methods) and you're wanting to get static things like Idle & WOT tuning dialed in. Tuning for driveability and economy can be difficult on a dyno since you struggle to emulate a real-world environment (airflow, drag, etc...).

As far as running higher boost.....ask specifically what you need to know. Are you wanting to know what exactly is required to run higher boost on your truck? Well, list your mods.....complete list. If you have an external wastegate, a 3 bar map, and a chip for 3 bar operation, then turn the knob on the wastegate controller to run a higher boost (up to the overboost limit set in the chip). If you're running a stock chip with a 2 bar map, then you really don't need to run a higher boost because your chip/map cannot read above ~15 psi. But know that going into higher boost (even with the right mods) is suicide without the ability to monitor data. Hell, going WOT on a stock truck can be suicide with data monitoring. Failure to do so will probably result in your next thread being about how to rebuild a SyTy engine......which, guess what......is available by searching.

If you want more specific answers than that, then you need to ask more specific questions.
