ECMlink DSMLink v3 need help?

[Vdubzr32]

ok so I just plug in my link previously purchased from someone on the forums. I downloaded the stock 2g software and fuel configurations.

the car starts but wont stay on will die if I don't keep foot on throttle. not sure what I could possibly be.

any help do I need something else downloaded.

the car has stock injectors,16g,afpr 43psi, front mount, recycle waste gate, 3inch intake 5inch cone filter,

not sure if the log is helpful I was on the throttle trying to keep it on

1. Do you have a stock '95/'96 CAS that sits behind the intake cam gear? If so, why do you have the "Use non-95/96 style cam angle sensor" box checked on the Misc tab?

2. Assuming you're using the stock MAF (based on the MAF Comp settings), why do you have the "Lock intake temperature and barometric pressure" box checked on the ECU Inputs tab?

3. Do you have a wideband that you're trying to log? It looks like you are partially setup for that based on the ECU Inputs tab, but you don't have anything setup in the pin assignments table.

4. Reset your deadtime to 0.

Read these links and do/check all the steps in them.

Do you have boost leaks? Whats your base timing set at? Your TPS didn't change if you were on the gas to keep it running. Your ISC is at 54 counts also, should be lower. I'm not great with link but just some things I noticed.

No cas set up I read up on that already.
I haven't wired the wideband to ecu pin as of yet will do that ASAP.
Stock maf
I'll continue to read up thanks

Do you have a 1g CAS, 2ga CAS (behind intake cam gear), or 2gb CAS?

Stock maf

Uncheck that box then. You don't want to lock IAT/Baro if you're on a stock MAF.

I know I don't have the CAS behind the intake I have a 2gb CAS

ok I got the car running. it idles well I adjusted it to 800rpms. I drove around the block to test it under normal and then pinning it just a tad to see how it responded. I also attached the wideband MTX-L innovate to pin 75.. not sure if the ecu is reading it.

I have 2 logs attached one on idle and the other whiling driving around the block. let me know what u see im very new to this so I read up on some stuff. just don't really understand fuel maps to well.

thanks for responding back

 

[snowborder714]

All I did was look at your idle and it's off. Please read through everything in here again, adjust, and repost just an idle log.
http://www.dsmtuners.com/forums/ecm...efore-you-ask-ecmlink-dsmlink-log-advice.html

Don't even worry about WOT, fuel/timing tables, etc. until you get the basics taken care of first.

 

[Vdubzr32]

I know I have an idle issue because the car idle super low and sometimes surges so I will get to that and check all the sensors and vacuum lines near the TB.

While doing this I think it's a good Idea to remove the emissions lines and block off everything else? Any advice.

 

[Vdubzr32]

I recently had time to get on and ecm link and play with it for a little bit today.. I tried to adjust it to run in stock form for now until I install the 880 pte.

check out the idle log see if you guys see anything out of the ordinary thanks

 

[snowborder714]

Your front o2 really isn't cycling. Are you sure it's working properly?

Your BISS screw needs adjusted since your ISCPosition value is off.

Looks like you also need to do some idle adjustment on both MAF Comp and deadtime since your wideband value rises over the course of the log and the AirflowPerRev value is too high.

Are you able to get the car to 180°? If no, that will cause some fuel trim issues. You may have to trick the ECU into thinking it's higher than it is.

 

[Chad1993]

Your TPS is off by 1% unless you actually have it pushed down to 1% physically. In RPM/TPS check the box under TPS and Idle Switch Controls, Then adjust the TPS by -1 until its at 0% in the log.

Like snowboarder said, The biss is off.

You do not need to ground timing or diag. Below is from the dsmlink forum.

2G Tuning : B.I.S.S. (Base Idle Set Screw)

--------------------------------------------------------------------------------

In order to properly adjust the B.I.S.S. your car must be idling at operating temperature.

Log the following values:
-RPM (~ your DSMLink setting)
-ISCPosition (~30 at idle)
-LearnedIdleAdjust (~140 at idle)

Adjust the B.I.S.S. to achive the above values. LearnedIdleAdjust is slow to react, so wait 5-10 minutes between your adjustments. Be patient.

Tighten B.I.S.S. or Clockwise
- Decreases RPM
- Increases ISCPosition, and LearnedIdleAdjust.

Loosen B.I.S.S. or Counter Clockwise
- Increases RPM
- Decreases ISCPosition, and LearnedIdleAdjust.

Thanks I'll look into it front o2. I have adjust the biss screw but seems not to make to much of a difference at idle. I'll continue I know after watching the idle video from ecmlink that my mad value are wrong and I need to adjust them after adjustments ill repost log. Thank you got the help

 

[snowborder714]

Keep in mind that when you adjust the BISS screw you should do it slowly and with small adjustments with a waiting period between. The ECU needs to see the change and make the adjustment to the ISC. You can't just crank it in/out and expect it to work.

 

[Vdubzr32]

The Tps voltage needs to be at .63v correct?
Also adjusting the the tps moves my tps to 1% then on the tps tab I have to adjust it to -2% so that my tps can read 0% at idle.

I still have a jumpy idle is it due to having 262 cw cams?

Ill post new log later today

most current update with BISS adjustment. and cycling o2.
Up loaded a 90 second Log

I have tried my best to get

ISCposititon 30
AirflowPerRev 25
TPSvolt .63v with motor off
ThrottlePos 0%

let me know what you guys think anything I missed or out of wack

 

[Vdubzr32]

any one have advice

Reset your InjBatteryAdj table to the factory settings, and that should get you back to a global of 0%.

as of right now i have 510cc evo3 injector installed and the global calculated to
-11.7%.

sorry for not posting the update with the 510cc yellow tops.

 

[WFO-TSi]

Right on, that definitely explains the global settings, but how did you arrive at the settings for your InjBatteryAdj table? I’ve never seen injectors perform identically at all voltages which is what your settings would indicate.

Can u explain it barney style at what your asking sorry but I'm a little confused. Injbatteryadj. I think I'm missing something here.

 

[snowborder714]

Direct Access section/tables. There's one titled InjBatteryAdj. It's used it you have your injector data points for deadtime based on voltage. Yours is a flat line and it shouldn't be. Click the double ended arrow icon at the top of the page and save the factory data points to the ECU.

ahhh ha i found it and reset it to stock setting wasnt aware it was flat lined. does this mean i have to readjust all the adjustment i had done previous?

 

[WFO-TSi]

Yeah that will definitely make a difference. You'll notice it less and less as the RPM's increase so it's not like you will be starting from scratch.

Start with idle and work up from there. You'll get it man

thanks man appriciate all the help ill post the new adjusment tomorrow.. im flying home to nj from west coast san fran now..

ok made all adjustment needed to hopefully this idle log is up to par..


90 sec log attached.... need that A ok approval thanks guys

Vdubzr32,

I just noticed how much airflow you are taking out of things at idle with your 50hz slider on the MAF Comp tab. You’re taking 25% out yet your logged AirflowPerRev is still on the high side of normal. That’s pretty odd when running the stock MAF. When was the last time you checked for boost leaks?

Its been awhile I believe hen I first installed link in july.

You think its a boost leak that would throw my air flow that off.
