TWEECER/EEC Tuner guys... teach me something new

My one piece of advice -- grab a copy of EEC Analyzer. Worth every penny. For example, I just used it to adjust my injector timing, and I noticed an immediate improvement in how the car runs (all by having the injectors fire 88* later than stock... )

I use the two highest load rows in the spark_base_table for wot spark tuning.

On the EEC Tuner I think they are the two bottom rows if I remember correctly. I use 36 degrees total and have it all in by 2500 rpm.

Other than the base table there are the mbt, borderline, & altitude spark tables which can add or subtract from your final called for spark value. There are functions as well as scalars that can + or - the value also under changing conditions like temp, load, etc.

When you datalog to verify your changes if you see more or less spark than you think you should then you can do two things.

1 Kill the mbt & borderline table by entering the value of 55 in all of the cells and looking at all the functions & scalars for conditions that are changing your called for spark value.

2 Just lower your values in the base table until your datalog shows what you want for your final spark. The downside to this method is that spark might not be stable due to changing conditions and under those conditions the pcm has been told to + or - the spark.

I don't remember if EEC Tuner calls their tables the same thing as Tweecer so I guess Tweecer speak is the only way I know how tell you the way I did it.

IM not sure what the EEC tuner is. Is it REALLY different from the TwEECer?

Either way...you can get a "base tune" from someone with a good setup and start with that.

can the tweecer program fix the shift points and correct the speedo for 4:10 gears? I know its been asked, never got an answer. And sorry for sort of jacking the threadd paul.

Yes and no.

Dave

well if you have tweecer r/t and a laptop it can correct for the 4.10 but the speed will only show on the laptop.......

Amen. The car revved a lot smoother down in the lower RPMs for me after I changed mine to the suggested 83* later.

Paul - I think we covered a lot of basic stuff in the thread I started a few days ago. I learned tons in that thread alone, and it was pretty much asking the same kind of questions you are asking.

Basic spark and fuel tables were explained pretty well and dialing in the MAF transfer seems to be a HUGE part in getting the car to run "perfect". Although, I'm not sure how much more "perfect" your car could get.

Joe, could you put up that link you are talking about.

i finally installed my tweecer and i have been reading up on "walt's method", where you first focus on getting the injector slopes, breakpoint, and injector/voltage offsets right. the idea is that the maf transfer is probably pretty darn already close right off the bat, because it came from someone who did flow tests on it. with walt's method, you can supposedly get your kamrf's between .98 and 1.02 all the time, which is of course the goal. then you can fine tune the maf transfer to make it perfect.

here is a link to info about it.

I have that saved and I plan on using it. However, my MAF transfer is no where near close. I'm using a Pro-M tune for my C&L and editing it as I go.
