where to start

[toppertopper]

Had a my baby tuned ,6 months ago ..Finally decided to take it to the track Saturday after i installed a new act 6 puck unsprung race disk and oem tob (went threw act 2100,act 2600 ,centerforce dual friction last year..Expensive very)....Ran high 16's -high 15's couldn't figure out what was wrong ..I know i didn't spend all that money to run that slow ..Next day i log it to see what was wrong..Everything is set at stock/tune is no longer there looked like a dam fool running those numbers with all the mods i have ...The last day for track is this Saturday need some help to at least get a decent tune and better time
Need something aggressive it is the last run of the year winter is coming here and i will be going bigger FWD OF COURSE

Also when i change from stock maf to 3" maf it will start and die

First thing to do is log your wideband. Can't tune without it...

While you're at it, read this:

make sure to log the relevant items.

i am logging all those listed their , as well as wideband .when i put link on my desktop to go threw it , i had to manually add the displayed values ..Then save as default , the laptop i used didn't have that problem.

for some reason I thought you were missing more items. Alright, well the logged values look good but there is no wideband signal being captured in any of your logs.

The frontO2 is not the wideband signal (0-5v), it is the simulated narrowband signal (0-0.8v) that the ecu uses for closed loop operation. You can see the ecu stays in openloop and the frontO2 signal is pegged high at 0.8v This is because you're not logging any wideband data to simulate the narrowband.

Also, you have a 0012 DTC...might want to check that out.

Why is your boost estimate only hitting 6ish psi?. You are also knocking after 5000rpm. Aswell as you are hitting 26 Deg of timing at end of pull are you on e85 or what fuel. That seems like quite alot of timing.

i am running 94 oct ..Not sure why its only showing 6 psi of boost , i did a blt to 25 psi no leaks , and the timing i have no clue about
think i seen on one of the logs timing hits 34
also the cel 0012 only pops up for a second close to redline here and there
also boost gauge does only get to 8 or 9 with mbc turned out (tried it on another car and it hit 30psi)

any one know why my wb isnt logging in link , i am showing 16-18 in wb ..or any log help ..if i click ground timing it stays at 5 during idel also

@3:48 it shows how to capture and display external sensors. Note that you'll need to be connected to the ecu.

The reason you have a 16-18 afr is because the ecu is running in openloop and the ecu is not using the (simulated) front02 to make the necessary fuel adjustments to maintain stoich.

ahh ya forgot about those ones, i added it and it wasn't moving stayed at 7.5.1 ..i think i had this problem before and never got a fix ,..Is there a wire i need to cut maybe , or a setting i have wrong for pin assignment ..This is the instructions i used to install the lc-1 wideband
did set the analog already

Narrowband simulation install (DB gauge, Logging, ECMlink v3 setup) [LC-1 sensor placed in front o2 spot]
Red wire – 12v accessory power source (e.g. cigarette lighter or radio)
Blue wire – chassis ground
White wire - ECU sensor ground (pin 24)
Brown – ECU pin 15 (ECU Pinout - http://www.dsmlink.com/images/forums/1GECUPinout.pdf)
Yellow – DB gauge’s white wire
(*Must reprogram Analog Out 1 values to match Analog Out 2 values using LM Config 3.15. Screenshots and software - innovatelc1orlm1install [ECMTuning - wiki])
Black – Calibration push button to monitoring LED to ground
*Note – The brown and yellow wires can be swapped in this scenario.

Brown – ECU pin 15 (ECU Pinout - http://www.dsmlink.com/images/forums/1GECUPinout.pdf)

If you wired it to pin 15, then it's wired to the EGR. As of now, in link, your LC1 pin assignment is for the frontO2, which is pin 4. So if you really wired it to pin 15, you need to change the pin assignment to EGR Temp.

Thanks , got it logging ..Now i just have to figure out why the front 02 volts are not cycling , its staying at .80 ..staying in open loop..Also added a new log with wb logging

 

[toppertopper]

well still no luck was playing with the tsp today , still cant get it into closed loop ..Tried another good lc1 sensor today and got the same readings ..So i know its not the sensor ...Any ideas

 

[c2ypt1c]

hey just saw your update. Cool you got it logging, but the reason the narrowband sim (and therefore closedloop) is not working properly is because you need to set the wideband to EGR Temp (used for narrowband sim), on the ECU Inputs page. Thats should get it going.

 

[toppertopper]

ahh i was trying that yesterday but it wasn't switching , today i went out clicked it kept saving it and finally got into closed loop ..Forgot it it needs to warm up some 1st,...Now i can finally do some more reading to refresh my mem to start tuning thanks ..Here is a log of it in closed loop ,..Goes into closed loop and starts cycling at 56.632..

 

[c2ypt1c]

finally got into closed loop

Great! A couple things I would do before continuing is reset your fuel trims (menu at top ECU->reset fuel trims). Looks like your fuel trims are maxed out. Also, your biss needs adjustment (ISCposition should be somewhere around 32).

 

[toppertopper]

I Reset the fuel trims..Think the isc might be bad it starts at 90 cold start and drops down to zero-3 cycles them at temp , i followed the steps grounding the timing and diag try to adjust bliss unground it goes to max 9 or 2-3 ..tried the starting turning off all different steps ..Have to find my ohm's tester , i did change it in spring and the car ran 5 times this year
