Help Tuning ... ECC Analizer: 370HP - 315TQ!! N/A

[SHOWYA]

(I bet i raised a lot of eyebrows just looking at topic! LOL.... These numbers are what ECC Analyzer calculated using WB data.)

Well i got my WB Calibrated correctly (W/ Dataq DI-148 USB) so its reading like it should. Did a datalog to calibrate the Lincoln 80MM MAF. Adaptive disabled and run 13:1 on the stabalized fuel table.

I used ECC Analyzer to make up the new MAF and uploaded it to the Tweecer.

The car feels super strong and the sound is amazing. I did notice LAMBSE2 In calcon to be at 18.300!!! ... at idle, after i ran it for a while. I did datalog.

FYI This is the second time have done this procedure. I disabled adaptive and dataloged. Created a new MAF calibration and ran the car with it. ECC Analyzer on HP/TQ is 351HP and 280TQ. So big differences after each calibration.



I did use the 1st MAF calibration with this second datalog to do the static 13:1 datalog again.

Here are the links on the data logs and the calibration file used.

Datalog with all the fixens!

So if any knowledgeable SHO gurus want to give me a hand i would appreciate it much.




EDIT:

ALSO ... I want to start cam tuning but obviously there isnt a profile on the MTX or ATX cams for the SHO. Anybody got any FORD connections on getting this info? Any poeple that work for FORD?

Just what are your trying to tune? If your trying to tune the MAF for top end you will set your adaptive off, and to make it easy you can set the stabilized fuel across the board. The best way is to do one log though a gear. I usually use 2nd so its not too fast to get in much trouble. Do it just like a dyno pull. Get the car rolling down the road click the log button and nail it then when you hit red line hit the log again. This will give you a similar deal to a dyno pull. Now you can go in the analyzer load the MAF your using. Make sure you have wide band O2 and OL clicked. Then hit calculate. This will make a new MAF curve to match the AF you were getting. Doing this a few times will get your top end on. But your also going to need to tune the low end of the MAF for driveablity. Doing this you will want to leave your adaptive on and its going to take time too see where your karmfs are going. This log is better off taken as you would normally drive around something like the one you have here. Then you almost do the exact same thing to tune the MAF except you use Fuel trims long and closed loop tabs.
And to note you will not be able to change your fuel stabilized and expect to just get that. It only stays looking at that table in closed loop.

Hope this helps.

Well this is some valuable infos for tuning (i'm still in the learning phase) , I'll get a copy of EA too , tuning seems easier with that.

Yes, I have been trying to calibrate to the MAF to my setup. All i did after i plugged in the data to ECC was select the WB and plug in the static AFR number (13.039) i did not know about the OL Filter option.

But even if i do in in 2 parts like you said ... then how would you merge the OL calibration and the CL one for a single MAF calibration?
Or is it that you would use the calibrated top end MAF calibration (OL) and modifiy it by applying CL filter once you have dataloged with adaptive on?

It makes more scense my second view of this.
But will it work as well just dataloging for sometime including runs thorugh second gear and stop and go driving using "BOTH" filter option in ECC?

It sure does!

nice numbers

Thank you son! still have to prove them on the dyno.

I know one day I will be dealing with this also, but man this sounds a lil like Japanese Pretty impressive numbers man!!

You keep using the same MAF calibration, you will find that the CL part will be up to your break point 2.19V? And the OL part above that. The two should run together quite well. The OL tuning will take some time, I have been playing with mine all summer and have it with in 2% now. Your going to want log your loop status as well. I would suggest switching it with the MPH log. And when your importing your MAF to tune the car make sure you import the MAF you used for that run and not the one you originally stated with.

Just for a note, I wouldn't rely on the dyno chart in the analizer it maybe only close if your MAF is accurate and your fuel injectors are on the dot.
FYI I have gotten over 310hp and 275tq on my almost stock 3.0L.

Im not understanding about finding the CL part being up to the break point. Can you explain what this means?

 

[Ishodu]

From what I understand its the point on the TPS (Voltage) where it goes between part throttle and WOT.

Cool i been learning more about this stuff. So my wide band oscillates 14 - 15 AFR i started to read about this and it happens because the calculated injector PW is incorrect. And this can be because of many factors including MAF curve injector sizes specified etc.

But as i been looking into this i also saw that my wide band compared to what CalCon reads is about a whole point off! so when it would read 14 on the gauge it will display 15 on Calcon. So i will be recalibrating my dataq. I used a different ground then when i originally calibrated.

If nobody knows how to do this ... then this is where you would read about it

http://www.72mach1.com/95-mustang-gt/lc-1-wideband-to-tweecer-install/

Almost at the end of the page where it says "Calibrate/Connect the DataQ"

The only reason i been looking more into this its because i drove a NSX with a wide band on it and when cruisin it displayed a solid 14.7 AFR i was like WHOA! And later on a 911 Turbo Porsche w around 600 HP and same thing solid AFR's!

Same thing in a friend's GTO with a tune, flatlined on stoich.

Bring that stuff up here and tune my cars.

You need to buy a Tweecer First!

im getting there, but its going to take some time and a few gas tank fills. My wideband is off. Laptop numbers dont match gauge. i did a correction on the database table for Calcon and it was a 3% adjustment (made it leaner) . But i been reading if its not grounded and powered properly that the numbers will be messed up. Its recommended to ground and power directly to the battery. But my battery is in the trunk.

Has anybody done any adjustments with the bored 68mm Throttle bodies on Tweecer?
Any other tips or "tricks" on tunning?

 

[Ishodu]

I grounded my WB to the ground for the ECC. And the power for it from the fuse box. My reading are dead on.

 

[SHOWYA]

Is the ground on the fender next to the battery? or are you talking some other ground location?

 

[Ishodu]

Thats the one Near the battery.

 

[SHOZ123]

Connect all the grounds together with copper wire and do not stack the ground lugs. You can ground to the same point but do so individually. The engine block is the best place or at least run a 8 ga wire from your point of ground to the block.
