finally have a datalog to work with!!!

[Blackened302]

so now what??

my buddy has EEC Analyzer and when we tried to calculate the Injector Timing table, every value that turns up is "N/D"... ??

it'd be awesome if one of you gents could take a look at the datalog file--i'd really appreciate the help

Its all in the things you log.

I am having an issue with my logs as no matter what load I log (loadx or load) it does not populate the correct load in the log. The next log I run will be with both loads selected to see what it does. That is if its ever below 100* and 55% humidity.

I actually manually (TALK ABOUT A TIME MF'er) entered in the load to the correct area and re-ran EA to get it to populate. I just made sure I selected the correct item 100% for sure before I did this...and it took a LONG time to even get enough data points to populate 40-50% of the table.

i double-clicked on the "CBAZA" payload and stuff automatically checked off...?

[blksn955.o]

It says in the help files of EA what you need to log for each tab to calc.

 

[Blackened302]

ok, cool, i'll have my buddy check what EA needs me to log.

 

[Blackened302]

WOW!

what a freakin difference, man... we're taking a break, but we got a chance to load a new datalog up (w/ the correct parameters, this time) and once i loaded the new Injector Timing table values, it made a huge difference in idle and driveability!

we're gonna grab something to eat then load a 2nd datalog w/ the new table values to see how that one turns out. the #'s are slightly different from the new ones, so we'll see how that goes.

 

[Blackened302]

here are my 5 datalogs (w/ the correct parameters, i hope, hehe) from today. had to give my buddy back his R/T and plug mine back in, but i can definitely say there is a vast improvement in driveability.

forgot to ask:
before hitting "Calculate" in the "Cam Specs" tab of EA, what should the "Injector firing event" be set to?

 

[blksn955.o]

its been awhile since I really looked into the event thing...it kinda went back and forth with some REALLY in depth theory the last time I did look. I think the end result was leave it at the default setting.

I really did not have too much issue with drivability...

I ran my first datalog threw EA and it was even BETTER with the slight changes it suggested. It really is a wonderfull tool for us self tuners in regards to drivability and taking a good bit of the guess work out of it.

congrats on getting some tweecing done.

 

[Blackened302]

so what is the default setting, then? thanks for the replies, man.

 

[blksn955.o]

I honestly dont recall... .

Might cruise over to the eectuning site and see though I am sure a search would turn up all the info you would need. I know they got REALLY in depth with it a year or two ago. It might even be on the stangtuning wiki that 007 put together.

 

[Blackened302]

is our stock maf listed in the "MAF" tab in EA? if so, which one is it?

I could not say anything about that as I've not updated my EA in years
but
You can see its 30 point curve in a GT or Cobra file

[Blackened302]

thanks, Grady. according to your method, the curve closest to the j4j1 curve in CalEdit is the W4HO in EA (makes sense, as W4HO is under CBAZA).

that changes the injector timing table values, but not by much. either way, it's better--i was accidently calculating the table values with the 93Cobra MAF setting which yielded considerably different results.

thanks, meng

I guess I just don't understand what you wanna do

Why settle for a t curve that is close to a j4j1 curve when you can just
use an unmodified j4j1 file

for the purpose of loading a tune with CalEdit, i did start w/ a j4j1 file, but for calculating injector timing table values with EECAnalyzer, you need to select a maf (in an effort to achieve more accurate results, i think).

after those values are calculated, i turn around and modify the Injector timing table in CalEdit (which already has the MAF curve that i was asking about matching).

You can make a "copy" of the J4J1 maf transfer. You basicly use the custom selection and save it as whatever. I had to make one for the 98gt maf I run so I used the stock numbers from a 98gt file and ran the log threw it.

If your using a J4J1 file to tune I would be leary of selecting a non J4J1 maf even if they are the same maf the transfers are alittle diff.

 

[Blackened302]

oh yeah, i was trying to make sure i had the correct MAF transfer in EA.

i was getting totally different #'s for Injector Timing Table values by trying to figure out which maf in EA was the stock j4j1 setting.

anyhow, tried out some new table values earlier and they did not work well at all--i had backfiring and poor throttle response.

i'm kinda at a wall, now--i made huge progress w/ driveability, but i know it can get better. dont' really know what to do now other than datalogging my current tune.

i'm running the 01 explorer throttle body, so i don't know how/if that has any effect on the tune.

advice? thanks, guys.

 

[blksn955.o]

I would make a custom maf curve in EA that is the J4J1 and save it as J4J1 and run the datalog threw it again. The tricky thing is that both the gt and J4J1 maf will work as it is the same maf so something will prob. get crossed trying to use the j4j1 bin maf and the W4 gt tune maf in EA.

So add the J4J1 to EA and run the log you have threw it and then make the suggested changes to the j4j1 tune and maf transfer. You really need to make sure your running the same maftransfer with the one your running on your eec even though they are the same maf they do have slightly diff. transfers.

You will have to run another datalog to get the post-tweec data and see were things are/run it threw EA again.

Thats right both Mafs are identical but on the PCM they have different curves , the cobra one is more or less 10% Leaner that the T4M0,U4P0,W4H0, curves, this is why you would usually best work slowly on the Cobra Maf Transfer on WOT and a must have WideBand, Since we dont have a 100% stock cobra or GT datalog with a Wideband we cant know for sure why is the cobra leaner or if they act like that, but also the Cobra has less timing. Maybe there is something about the injector size on the GT that had to be much more rich to compensate, and the cobra can have leaner without detonation from the 24lbs.

I would like to suggest if you are working from cero on a J4J1 Base binary , and having a stock MAF , Keep the Cobra MAF transfer and not mix the GT & Cobra Transfer between calibrations. This will be better . From my point of view
