Also, is there somewhere where I could find basic definitions to what some of the terms mean in the tweecer and EEC Analyzer, like MAF and then it has really large numbers, peaking at 954. But I have no idea what the 954 means. So yea, if there is a link that I could read up on that would be great.

954 is most likely kg/hr. i saw a peak of about 950 kg/hr for my maf on my final dyno run.

I know you don't wanna here this BUT

The only way I know to learn this stuff is lurk around on the various sites where the knowledge is.

Of cource the two Tweecer sites can help and I think the moderator of this board has a tuner site.

I have seen some very good basic facts on this forum by a guy named Steve and his Tweecer name is Desmo something.

I found that if you spend some time on the sites and focus on the Cabaza strategy that after a while the whole ball of wax kinda sorta starts to make sence.

You just gotta dig for the info and I have had some help from some of the guys on the sites when I asked for it.

As for the 954 thing, I do believe Greg is right on with his answer. If you are pig rich on the high maf voltage points or your fuel table values the kg/hr values would be higher than say if you are too lean. I bring that up cause, yes, you can see air flow through the motor with this value but they can be misleading.

Sounds good Grady. Just get one tweecer forums and stangtuning.com? Any others?

I mostly use the Tweecer forum but there are some very knowledgable guys on the Yahoo Tweecer forum but the search engine on the Yahoo site is not so good.

The cal file you use came from the Tweecer site jfyi.

Hey guys, I actually found a score on a Tweecer R/T for a decent price. This is what the guy says...

"Everything needed to use the TwEECer is included, except the software, which you just download from the web site. The programs in the the unit now are T4MO and J4J1 stock programs so you would have a starting point to start modifiying.

For payment you can either send a money order to me here or I can also do paypal if you want it faster."

So if he sends me all the hardware, all the software is downloadable from the website? If it is, I should score up one by this evening.

This computer stuff throws me for a loop...

Yup. When I got mine, all it came with was the TwEECer itself, USB cable, and 5-position switch & cable. The software I got from www.tweecer.com.

You have a laptop, right Joe?

Yup.

I have a new one coming, but that may not be here until next week. I'll use the old one until then.

I was wondering if I should play with the injector timing? lol...I have no idea where to start with this thing.
Leave your injector timing alone for now, I have tried ever number from 120 to 720 and it made little to no difference

Is there anything I should download to analyze my datalogs better? I know of EEC analyer, but is there anything that is free? What about log analyst? How do you use that?
Log Analyst is very helpful

I developed a surge at start up since I made a new CAI that puts the filter in the fender. Really weird, but I think if I mapped out the MAF transfer than it would start up better? It doesn't die, just surges and finds the desired 848rpm idle. What do I need to do to fix this?
Make sure their is nothing mechaniically wrong, no vacuum leaks before trying to Tweec out this problem

How can I prevent the computer from pulling timing when I shift (not powershifting). Do I change "spark_min_for_tip-in_retard"? Right now it's at 21.
This value will be your total timing for 3/10ths of a sec when you shift under load. I usually set it to my highest total timing value, in your case I would set it to 30* and adjust it up as you adjust up your other timing tables, or with whatever you feel safe with.

Thanks to anyone that bothered to read this long, boring ass thread. I'm starting to think tuning is not that fun, oh well, I'm learning alot.

Thanks

Does this tip-in_retard scalar value ONLY get used for that .3 sec upon release of the clutch (clutch switch action) (at load)? IOW (for clairity - not suggesting this)- with a disabled clutch switch, this scalar would NEVER get used?

What is the value of the load "breakpoint" the the EEC uses to determine if the shift is under load? I'm imagining there must be a hard coded value ( such as 50%) to determine when to use this and when not to. Is this LOADX or LOAD?

NO other adders or multipliers for spark get applied during that .3 sec, correct?
