I'm not quite sure where I violated the "rules" in my post about my cold start problem, but there sure seems to be a major misunderstanding somewhere. I was asking for HELP about my cold start problem and somehow it was misconstrued big time.

I am trying (very unsuccessfully I might add) to learn how to burn chips and find out what is causing the problems that I am experiencing.

Or is the problem having a third party burn my chips or change things that I request. If you haven't guessed, I don't have any of the needed equipment or more knowledge than I can gain by asking questions at this time.

Believe it or not, once I can learn the basics (from some other method of "just start changing things" and see what happens), I'm sure my questions won't seem quite so insulting to some.

Why am I having such a difficult time getting answers to my questions?

We all had to start somewhere and I'm at the very bottom rung of the learning curve. I'll be the first to admit that I really don't know very much at all, but that seems to aggravete a few folks.

I've read the stickys and they don't seem to make much sense to me. I'm a very methodical person when it comes to learning something new, and I WANT to at least have an idea of what I will be changing and what to expect from those changes or what is the root cause of problems that I am currently experiencing before I start making ANY changes. Why does that seem to be a problem?

I'm not trying to cause a stink, but why does this seem so difficult?

Thanks

 

you didn't burn your own chip

 

It's hard for everybody at first. You have to jump in and experiment in order to learn.. Once you start, you learn more things faster.

I appreciate the knowledge I've gained from reading these forums and experimenting with tuning. I can't believe how much I've learned in the past year. And you know what?? It's because of guys like Grumpy, RBob, Traxion (the list goes on) who have generously shared some of the things they've learned and experienced with the rest of us so we can LEARN. So I support their unwillingness to help in this situation. You need to burn your own chips, that's why you got jumped...:nono:

 

11sORbust,

I REALLY want to, but I would like to know what I'm doing (or at least have an idea) before I do anything. Plus, and please don't take this the wrong way, but to repeat paragraph #3, I don't have the equipment (software or hardware) or the knowledge at this time.

Do you (or anybody else) know of anywhere that I can download for free, or at a very low cost some software that will at least let me see what can be changed and how?

For some reason this is becomeing very exasperating trying to gain some knowledge before I "jump in" so to speak.

 

If you need to ask this -- then that proves you really haven't read anything. Come on man ! Even I got that far Just go through the stickies at the top of the board -- and when you've read them through once -- do it again, and again, and again.

then, see if you haven't already came across these links :

Good luck !

 

To answer in order, and this is mind not directed at you as an insult, but as this board and members will attest, been burned soo many times by those that come here, get what they need then make fast bucks from individuals such as yourself. The information that has been "databased" here by the members here has come from long hours of hard work decyphering various ECM's and masks. So yes were kinda protective.

1. Yes.. the majority of the members here are not for profit, and are commited to it.

2. Get the equipement to read your aldl, (a cable, a simple 1 trans or 2 trans will work with your TBI), one of craig's adapters for your eprom, a couple at29c256 flash chips, a williem programmer is under $50, and somesort of program to edit the chip (lots of freeware) and your good to go.

3. See my opening statement.


So get the stuff, make a datalog of your cold-start issue, post a question with your datalog, and we will be more than forth coming in helping.

Sorry, but it's because of others lack of courtesy, that we respond this way.

Bob

 

OK, first off thanks for the replys and letting me know why I got such a hostile response. Secondly, I guess I've got to do some more reading. Lastly, thanks for the links. I'll be checking them out...in detail.

 

BINGO! Houston we have a hit!

I found what I was needing at the tunerpro website. That little bit of freeware sure cleared a LOT of things up in my rusty 'ol mind. Now a lot of the threads are starting to make sense. It's amazing how a little bit of the correct information (that you need) can clarify things.

Now it's time to look at a buncha bins and compair them to the stock bin (once I find it) so I can see what changes were made for what reasons. Thanks again folks!

 

Wignutt I have a Prom Intro I am working on and the basics To get started are complete. I would like to See if it helps you understand What is needed to Get started and Clairify Some things. Please Give me your Email and I will send file.

just my

 

MTPFI-MAF,

You betcha, the basics are exactly what I need. I've been doing a LOT of reading tonite and some of it is now starting to make sense.

Here's my "public" e-mail address, I'll reply with a different one.

longgrifle@yahoo.com

THANKS!

I'll let you know how much it helps.

 

Its not quite as hard as you think. The tbi ecms are relatively user friendly. Once you open up the window and begin looking at the tables it starts to sink in. Start small with the constants and such at first to get used to things and move on to the tables. The only hard part is finding out what the motor really needs.

 

I find the c3 code to be a royal PITA to explain to people. The p4 stuff is much better because the tables are ment for saving space. Example; his cold start problem in the 61 mask is a combination of 3 2d tables! A 4th if you count the cranking AFR vs cts. You have the desired AFR vs cts, desired AFR vs map, and choke AFR vs cts. To come up with a good visualization you need to use the software I'm going to release soon . It combines the tables into an easy to understand visualization (3d surface plot like main VE table). It also does the same thing with the spark extender and VE tables. I haven't spent enough time with it since I got a romulator but now I'm working on supporting the romulator with this program.... should be interesting.
Wingnut, glad to hear you're understanding things but I wish you'd understand why we get so annoyed.

 

Went back and looked at it and I guess Ive forgotten how ghetto it really is.

Its:
Initial choke AFR
open loop afr adj. vs vacuum
open loop AFR vs cool temp
choke AFR adj. vs cool temp
decay multiplier for choke afr adj. vs cool temp
crank afr and its adjustments

EDIT: misread something.

Re-edit: almost forgot the bpw correction with cool temp.
