Does everything look right on this log?

[Nick456]

Just got done tying up my 16g supporting mods and grabbed a data log of starting the car for the tuner.
Is this what the tuner needs to work off of or am I doing this wrong? Id hate to waste his time asking a ton of newb questions. Ive done plenty of research and believe ive done everything correct? Thanks for the help

This is first startup attempt after installing used dsmlink, then installed an innovate lc2 wideband and wired it into the ecu following ecmlink wiki instructions, and removed stock injectors and installed FIC 1220cc.

1) You need to post your entire setup
2) why is your idle 1100? does it need to be that high?
3) Your wideband is not assigned to your rear o2 pin. Go to ecu inputs and change it on the top table and be sure to save the pin assignment.

 

[Nick456]

Thanks, ill fix the wideband pin assignment tonight. As far as the idle being set so high, i guess that's what the previous owner of dsmlink had his set at, ill fix that as well

TPS volts is only at .14v; should be around .63v at idle, iirc. According to your ECU data, it's been rescaled by a fair bit. I'd readjust until it's closer, then rescale.

Edit: just noticed you had a throttle position circuit check engine light. What's going on with that?

Also your misfire DTCs have been disabled. Might want to re-enable those.

 

[Nick456]

My setup is stock motor, evo 3 16g, FIC 1220cc injectors,rewired walbro 255 fuel pump, dsmlink v3, fuel lab fpr, innovate lc2 wideband.

 

[Nick456]

Oh, and a 1g N/T throttle body. Almost forgot that since previous owner did that. I believe that sums up my setup.

I'll have to look into the TPS circuit CEL. Any pointers on what to check out? Also, car ran great right before i installed dsmlink, injectors, and wideband. I made sure to start the car after doing the fuel pump rewire and afpr to confirm i did those two things correctly. This is literally my first log ive ever captured. Got all this together last night. So super new to all of this obviosuly. Thanks for the help

 

[Nick456]

Actually, should i go through and set everything back to stock? If i remember correctly there's an option for that on each tab. Then grab a datalog and go from there.

Also,
Are you running Speed Density or MAF?
What boost controller?
Don't see O2 signal?
Don't see fuel tab?

I'd reset everything and start from scratch after you make sure all your sensors are working properly. your log seemed like a cold start since coolant temp didn't move much, or your sensor isn't working properly.

What year car do you have?

Here's the diagnostic flow chart from the '96 Talon service manual for P0120:

You must be logged in to view this image or video.

I also noticed your power steering pin is fluctuating between loaded and unloaded. Where you turning the steering wheel at all in this log? If not, you might have something going on with your connection at the PS pump, or wiring. IIRC, that connection is grounded by the PS pump when under load, so it might be disconnected or touching something. Look for a little wire on top of the PS pump.

 

[Vegas Smith]

Make sure have the latest software and firmware as well. I couldn't view your fuel tab for some reason.

My car is a 1997. Ill check that out when i get home and get back to you. The help is much appreciated. Im definetlty going to try setting everything back to stock settings as well.

Im running stock 2g maf and a hallman mbc. I noticed i couldnt find the fuel tab either? Figured it was just me not knowing what im doing though. Just learned in this thread that i need to have the wideband pin assigned so ill fix that as well today. As for coolant temp, that was a cold start so thats why.

There seems to be a lot wrong.

TPS adjustment, CEL, ECU inputs could be right, but you aren't logging them at all.

Do you have an MDP sensor?

Did you notice that you are asking for 40lbs of boost?

It doesn't appear that you have compensated for your injectors anywhere

uncheck "disable airflow smoothing with SD Operation" on Misc tab.

Do you have a non-95/96 Cam sensor? if so your fine, if not uncheck the box.

If you are trying to run speed density, your VE tables are crap

The log wont do us much good till:
1) you can achieve a steady idle
2) you can get the car to operating temp (above 190 deg)

Currently it looks like your ISCposition is way out (should be 30) and your "airflowperrev" is out. should be .25 at idle. These are probably related.
I am shocked you have 0% fuel trims across the board expect for we cant see LTFTlow which you should capture. This tells me that your setting for when these are adjusted is wrong.

I suggest you go into your DA tables and and use right click>"toggle stock values" on every table/chart. I just did that to your log and there are some big changes that I'm not smart enough to understand, but I would think would be important.

In summary;
1) Get the latest software
2) fill out a profile and the form in the link i posted
3) fix you DA tables
4) fix your TPS error
5)compensate for your injectors
6) Input your MDP (if you have one) and wideband into your log so we can see it
7) turn of "enable boost control" before you hurt yourself
8) do a boost leak test (why not?)
9) take a log and post back

That might get you out of the woods so you can at least get the thing to idle right.

See my post above, but you are currently asking the ECU to control boost and using a hallman.

 

[Boomdeeze]

@doubleclutch covered a lot of what is wrong with your log and questions we will need answered before we can further. One more, are you running an oem front o2 sensor or are you trying to simulate it using the wideband? The stock is not cycling and if you are simulating, you don't have it assigned correctly..

 

[Nick456]

I went through and adjusted everything I could figure out. I also sent a firmware request to ecmlink, so ill get that updated once I have the firmware. I know that everything was working perfect and car drove great before installing dsmlink, so its not like the car had issues keeping it from driving before this. This is the next best log I could come up with, and it doesnt exactly seem correct to me. I am running a stock o2 sensor and welded in a bung for the wideband down stream. It really doesnt help at all that this is my first time doing anything software related on a car. Maybe I'm stepping into territory that needs handled by the tuner at this point? Really appreciate the effort to help me though everyone!

 

[Nick456]

I'm clearly clueless on this . I had no problem getting the bolt ons installed and things wired in, but this is simply beyond my understanding for now. Tuner is going to help me get all this straightened out on tune day in about a week. Much appreciated on the help.

 

[Vegas Smith]

Nah man, it's just lots of little stuff that you're figuring out how to do. Even if you do get someone to tune the car, you absolutely should be competent enough to set the car up to run and idle yourself.

There is something wrong with your wideband. It may be that there car is ridiculously rich because you haven't adjusted for the bigger injectors (where the hell is that fuel tab? totally confused on that). I wouldn't mess with the car until you can get the fuel tab available to make injector changes.

 

[Nick456]

Yeah you nailed it, it's figuring out the little stuff at the moment which is proving to be quite a struggle for me haha. Definitely a problem that the fuel tab is MIA, hopefully updated firmware takes care of that. If I remember correctly the wideband was reading fine when I had the black box ecu still in the car. As a first project car in general and first time messing with link, im feeling a little in over my head. Nothing I wont be able to figure out with time and effort though

 

[doubleclutch]

You still need to go into the direct access portion and right click on the tables and "Toggle stock values" I would set every single item you can in there back to stock since stock was running fine (black box)

It is odd to me that your fuel trims are zeroed out when you are running so rich that your O2 wont cycle. Really need to figure out that TPS error, that probably isn't helping.

SCRATCH THAT
You aren't making it into closed loop. Your fuel trims won't adjust until you do. You may have not let the car idle long enough. Closed loop can take about 45 secs on a cold car to get the o2 heated. if you can get the fuel trims to adjust, it might start running a little better where we can get other things fixed.

Does downloading the new software restore your fuel tab?

I'm new to tuning as well but I can now read logs and understand what's going on for the most part. It's really not that hard. All the information you need are here and on ECMtunings website. Plus most members here are willing to help.

YOU CON DO ITTTTT!!
