In my opinion, the log is useless without a wideband if you're talking about speed density. You can't tune the car without it and should not proceed to do anything until it's installed. Get the wideband wired in and then grab a new log.You should also utilize the lock factory sensors feature...

The only slightly off thing might be the upper psi limit at 5v since 3 bar is 43.5 psi.The way map sensors work is they need 1 bar (or 14.7 psi or -29.53 inHg for vacuum) for atmospheric pressure and then the rest can be used for boost. So your 4 bar sensor can read down to -29.53 inHg of...

I have this removed from my 2g ECU and am running a fuel pressure sensor on that input without any issues.

Marty, I'm not sure if that checkbox on MAF Comp tab actually has an effect since the MAF type is Stock after reading the help text. Sounds like the logic is built in that if MAF type is not Speed Density, it won't be an issue.Just a note when dealing with firmware updates - ALWAYS make sure...

Assuming you have a MAP sensor installed in the car, here's how to assign it in the software. http://www.dsmlink.com/wiki/installnewsensor

Sounds like you might have V3Lite.Check some of the screenshots at the bottom of the page and compare to what you see. http://www.ecmtuning.com/wiki/v3litescreenshots

Have you played with TPS Offset/TPS Scale values in link to see if you can get it reading properly at both ends?

When I set up 1g throttle bodies, while there is a spec for how to set the idle switch/throttle body stop (@steve has posted about it before), I only adjust it to make sure the throttle body doesn't stick. I set it in place, lock it down, and then open the throttle body by hand and let it slam...

Please use threads for the initial topic only. If someone goes to search for that code and sees a topic of 2150 idle issues, they might not look in there.

Honestly, if everything else looks ok fuel trim wise, I wouldn't worry about those two values. You will never get every little detail correct when tuning. Unless you notice a drivability problem, I'd go with what you've got right there.

This is not the case with Fuel Injector Clinic injectors. Whatever numbers they give you are the numbers you plug into ECMlink.Do you have a picture of the data sheet that came with the injectors that you can post up?

How to test an ISC. You might be confusing it with the TPS that will show value changes with throttle application.http://www.dsmtuners.com/threads/dsm-isc-motor-testing-replacement.386663/

I'd start by checking the hardware parts before going anywhere with the tune. It will mess the idle tune up if it doesn't run properly.

1. Have you checked your ECU to make sure your ISC drivers aren't blown? Have you tested your ISC to make sure all the coils are good?2. Did you adjust your AFPR with the vacuum line on or off?

gsxeclipse102 is correct (and thanks for reminding me) - I can't suggest anything as I don't know which injectors are in which port.Try contacting FIC and have the numbers on the sides of the injectors handy. They should be able to pull up the data and recreate the sheet for you.

That doesn't fully correct your fuel settings. Can you explain why you have a global deadtime adjustment of 279 when all of your deadtime is currently adjusted already in the DA table? You've also probably got some individual injector deadtimes on that sheet that you could plug in. Make sure...

I want to see the whole sheet please, not just that table. There's other info on there that you can input into link.

I'm aware of this (and worked with them to try and get it switched to match link, at least for the DSM guys). What I'm saying is you have fuel adjustments in multiple places and it could be causing you issues. If you want to post a copy of your injector sheet, I could create some new fuel...

Comments below are based on the first log posted.I see you have fuel adjustments in both the Fuel tab and the InjBatteryAdj table. Is there a reason for this? Ideally, you should have just copied the data provided by FIC into ECMlink, assuming you bought the injectors brand new or the...

If you have a log that you're willing to post, throw it up. I'd be curious to see it.The injectors should handle that horsepower, no problem. I don't know off hand how 60 lbs/min translates to horsepower though. The pump (off hand) I'm not sure about. I'm at least assuming the pump is...

One question that hasn't been asked - is your tune spot on, both from injector settings and SD table (assuming the mod list in your profile means you're on SD)?

I've been adding this product when I run ethanol and haven't had issues. I run a tank or two of 91 (ethanol free) through over the winter so the car doesn't sit with E85 in it. https://www.amazon.com/Lucas-Oil-10576-Safeguard-Conditioner/dp/B004FW77F0I don't think you would need to run race...

Leave it in. I actually wrapped some electrical tape around it and the wire to make sure it stayed in place.

Just curious why you're suggesting a tuning solution based on fuel choice. The choice has nothing to do with the fuel you're using. I've run three different fuels in my car and link has handled them all.I'm a fan of link because of how user friendly it is and the large community that's...

MAF - MAF value as used by ECU MAFComp - MAF value after compensation slider adjustments have been made MAFRaw - MAF value as measured by MAS or GM-MAFAll values listed here: http://www.dsmlink.com/wiki/dsmlinkloggableparamsFor your GM MAF, you'll probably see idle MAFRaw values around the...

WOT for a MAF? If so, you don't really need a video to describe what to do, and that info has been posted around here at least a few times.WOT for SD is a much more involved video and would probably take a lot of time to really explain well.

Looks like the output wires do come out of the back of the gauge. Just lengthen and run to the ECU. No issues in doing that.

Posting specific topics on videos you'd like to see would probably be more helpful to them so they know if they can knock it out quickly or not.

Might you be referring to the tech article I wrote for the LC-1 install variations? If so, this isn't the first time someone has gotten them confused. I'm wondering if I should create another for the MTX-L (and any other variations Innovate has come up with).

If the location you're putting the gauge allows for a deep gauge, then the MTX-L would probably be a good choice. Otherwise you'll have to place the control box for the DB package somewhere in the engine bay if you plan on replacing the front 2 sensor.

The MTX-L has the wideband controller built into the gauge where the DB setup has an external box controller. That's probably the main difference, other than how the gauge looks. They should both perform the same.

The Innovate widebands play very nicely with ECMlink, so you'll be able to get it reading properly.Yes, they come with two outputs which can be set for one wideband and one narrowband. However, with v3, you just need to input a wideband signal and the ECU can produce the simulated narrowband...

Here's how to get rid of the P1500 code. http://www.dsmlink.com/wiki/direct_access_changesIf all your other fuel tests have passed, I'd try another set of known working injectors.

Nice data point. Sucks to hear that happened, but I guess it could've been a lot worse.

You got it!

You can just look at WBFactor and see how much to adjust your MAF Comp sliders by and in what direction (positive = up, negative = down). This is much easier than doing the math by hand :)

Good call on the CAS/ECU combo!Definitely go through and look at all the settings. Did you get the ECMlink package used from someone else? Maybe their settings were left in. If so, let me know and I'll get you an updated settings file to load in that should work better.

I'd start by zeroing out your Fuel sliders. No idea why you're pulling that much fuel via the sliders.You also need to make sure you swapped spark plug wires and checked the invert CAS box. http://www.dsmlink.com/wiki/swapplugwiresTry those and see how it runs.

Please calibrate your wideband as well while you're double checking things.Speaking of that, where is your wideband in the exhaust track? I see the rear o2 input is being used - just want to make sure it's not behind a cat or something.

The one thing you'll have to look into is around 4k RPM there was a big lean spike in the log you posted. Even though you already added some fuel via the MAF Comp sliders, it was still asking for about 30% more adjustment. Keep an eye on that area as you progress through tuning.

I'm just slightly confused that the previous pulls indicated a ton of MAF Comp correction (as you can see in the file I uploaded), but the latest pull you posted only indicate a slight correction (10% or less). I would make the corrections needed based on your latest pull and get AFRatioEst and...

Looks much better. You've still got some airflow tuning to do, as you can see your AFRatioEst and wideband lines don't match up perfectly. Tuning a MAS is easy - look at WBFactor and adjust appropriate MAF Comp slider (based on current MAFRaw Hz level) that amount and in that direction.I'd...

I had replied to this comment you made in another tuning thread.The box that is checked comes that way by default. It's a safety thing so that if someone dials in their VE table using the MAF Comp wizard, they don't inadvertently apply two different airflow corrections when they switch over to...

This is an issues with the software install on your computer. Go download the full install, run it, and then do the early access install. This should fix the issue.His MaxOct table is targeting 11.2 AFR at WOT.OP, is your fuel pump rewired or are you still on factory wiring? Next time...

Not sure how I overlooked that Craig! I stared at that for a while and it just didn't click :pYou need to select the proper choice in the Wideband drop down in the image above. Then go to the NBO2 Simulate tab and turn that on with the proper settings. You'll want to do some searching...

@Calan Any idea what would cause the fuel trims to swing this much between o2 cycles? I see the car is idling really rich, but I'm not sure what else might need to be addressed to get it stabilize and hit stoich.
