ECMlink new to v3 help ,

[toppertopper]

Just got it , zeroed out the maf-t ,set the injectors , set 3.5 maf , set lc-1 wideband and set the sim for front 02 sensor (thats where i put the wideband sensor) ...I still have more videos to watch just need to get a base tune done so i can drive it ..Thanks
also sound like rev limitter once it hits 3k rpms
tunning for 94 oct gas

Lol posted at 4:20 .... What were you doing up at that hour tuning your car huh? Haha


Anyway nice job with figuring it out on your own. Read up some tutorials and get familiarized then you should be tuning soon enough no problems.

 

[liquidsilver]

Awesome now you just gotta get your mods list updated. And the videos are a huge help for getting your initial tune. Watch them a few times.

You should add a few more things to your captured values. Tips: http://www.dsmtuners.com/forums/articles-tuning-ecu/262460-basic-dsmlink-tuning-guide.html

Shows 0820 for me.


Log more items, as much as you can.

First things I noticed is your LC1 is stuck at 7.5:1. Your Fronto2 is not cycling and is pegged at 0.80v. Your TPS value is set at 0.53v and should be 0.64v (requires manual adjustment of TPS). MAFComp is not showing any value. Your RPM is 300 higher than what you have set.

I'm uploading a changed file for you to start with. Why did you have both the sliders and DA table for fuel and timing messed with? Why was your knock sensor only coming on at 100% throttle?

First thing you need to do is set your throttle position and get your wideband working. It's possible you wired it in wrong (if you put it on the rear o2, just switch it around on link). When that is working, upload a nice long idle, no throttle and log ICSPOsition and LrndIdleAdjust at the least. If you have a log value for your coolant fans, put that on too.

For the time posted i get up all hours of the night to come on

Thanks and to use that i just open it and save to ecu right ? I doj't know why the wideband isn't cycling i hooked it up right and it is in the ,front 02 spot ..sliders and da tables i never touched , maybe the previous owner ?? Knock sensor , not sure why it only comes on at 100% how do i check or fix that ? i will work on the rest today thanks

 

[LiquidX]

Yes, just open and save. You can review the changes I made.

The knock sensor WAS set to 100%, that is adjusted.

I would just look over the wiring again and double check it's the correct wire referencing a pin out. Should be there middle white wire on the plug.

The one next to it is the rear and the white wire adjacent with a space is the knock sensor.

I changed the Sliders to zero them out.

Make sure your maf is plugged in too since there wasn't a Hz signal.

 

[toppertopper]

Loaded it up , car wouldn't start ..Unplugged the maf-t from the gm-maf and it started right up ....let it idel while logging , then i plugged the maf-t back in , The car died , tryed to start it no go ....When i zeroed the maf-t i just put everything to zero did i do it wrong ..Never played with the maf-t before ..Previous owner had it tuned ..Posted a long of it also

 

[LiquidX]

You still never adjusted your TPS to the proper voltage.

What injectors are you using and did you check your wiring for the wideband? You do have a CEL for the MAS unless on this log.

If you are on 450cc injectors you should have your dead time at 0 I believe. I would suggest reducing your deadtime to 0 and if that doesn't work, add dead time in increments.

 

[toppertopper]

I didn't adjust it yet because of the maf problem with it unpluged ,wont that start to hurt it ...Or will fixing the tps fix that ?It wont start while its plugged in
injectors are 450cc ...I do have some rc 750cc injectors waiting to be installed ..Should i install them then start ?
Checked the widband wires everything looks right this is what i followed
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.


Edit : i adjusted the tps in dsmlink then , noticed it is now sitting at .67 not started ...and 5volts at wot 100%

 

[LiquidX]

I prefer to adjust the TPS by had while watching the TPS voltage value on link (car does not need to be running). Once it is at 0.64, run the TPS adjustment tool in link. Do a datalog (car not running), press gas pedal fully and release. Run the program and continue until there are no more adjustments done.

Get your deadtime down towards 0 and try again with the log.

 

[toppertopper]

Just did that heres a log ,still wont start with maf-t plugged in

 

[LiquidX]

Did this run before with the GM MAF?

If you have your stock MAF try using that to see if it runs.

I'll look at the log when I get home.

 

[toppertopper]

Yes it ran , and still does when i put my old ecu back in , but as soon as i put in the ecu with link ,It won't, even if i zero the maf-t out ,..It doesn't ...To zero everything out i turn all the nob's to zero , is that right ?
I don't have another maf laying around and i have a custom intake, so tossing a maf in isn't an option..

 

[LiquidX]

I never used a translator so I cannot help you there. Did you set DT to 0?

 

[toppertopper]

yes , dt is at zero

 

[fallenauthority]

Did you check your ECU for internal damage? I find it odd you can run off your stock ecu but not the one with link with stock settings.

 

[toppertopper]

Found the problem , i had to set the maf-t for 450cc injectors ...I will let it warm up and take an idel log and we can go from there...i will post in 20-30mins ..Also thanks for the help

 

[LiquidX]

Again, you visually and physically checked your wideband connection and the wire it's soldered to?

Since you are running NBS that NEEDS to be cycling unless you lock in closed loop mode. Are you still getting a CEL for your MAF?

 

[toppertopper]

Ok , i don't know what happend it was ideling fine i started loging while it was warming up , after a bit it just died and wouldn't start , i see it shows tps going to 1% + but i did not touch the gas peddle...I also took another log while trying to start it after ...
Yes i double and triple checked the wideband wiring ..I think i do need to reground the button tho ...The wideband is moving on the gauge ?

The cel light for maf ?? in the other thread i had ...That was for a 93 talon i use to have(sold that one) ..

 

[toppertopper]

I Finally got it , had a beer sat back and tryed some tweaking..Slid some of the maf comp up , started the car pressed the gas holding it at 1krpm's , adjusted the tps ..Bam it starts and idles ..

Now to fix the wideband , it stays at 21.9 (on the gauge ) press the gas and it goes to 15.x then jumps back up ..Could be the power and ground i used for the gauge ...As i see my boost gauge is not working properly

Any other adjustments i need to make or look at ?
Thanks again for the help

 

[Calan]

Since you are running NBS that NEEDS to be cycling unless you lock in open loop mode.

Fixed.

Since you are simulating the NB and your WB isn't logging, the car is stuck in open loop and there is no way of telling how rich or lean you are running.

Personally, I would plug a stock O2 sensor back in while dialing in idle and cruise. This is preferred anyway on a new tune unless you have verified your WB is accurate.

You also need to fix that leaking VC breather port (just a hunch.

 

[Calan]

You also need to fix that leaking VC breather port (just a hunch.

Scratch that. Forgot you are running a GM MAF (in blow-through I assume).

 

[LiquidX]

I I don't know why I keep getting open and closed backwards. Maybe I just haven't been having car talk for over half the year which is causing it.

 

[Calan]

I don't know why I keep getting open and closed backwards.

Yeah... crack is a bi***.

 

[toppertopper]

I will toss in the stock on in the morning and take another log ...Thanks
