Yes I did. Are you guys suggesting I set it up so I am running both?

Yeah I think in the long run I would like to weld in a second bung for the wideband and the narrow band. Let me know what input you will be using for this as I am unsure what the best option for that.
I had originally attempted to get my airflowperrev to be around that and the idle was very unstable, when I shifted it under that it evened it out. After the recal I will do a full retune, that way I know everything is fresh. The roads are looking clear enough so I will go for a WOT run after calibrating the wideband and before setting up my global to see how that looks.

Keep in mind the 1G's only had one O2 sensor stock, and less overall ECU inputs, so it will take a little more work than you probably think.

That was why I hadn't put it in in the first place, I never really found a concrete answer as to where to wire it in.

Alright so I went out and as you can see my global looks good based on the little WOT run I did. I am not sure what to do about my deadtime cause it's getting to the point that it will be down to zero to get my fuel trims to line up, should I start fresh with the calculated global and then use the deadtime that was suggested in that link and go from there? Thanks for all your help guys, I really appreciate it! https://www.dropbox.com/s/kvxt8q5xm1ug6kf/log.2014.01.29-02.elg

The deadtime settings are weird indeed! You definitely have too much deadtime, because if you do the SD VE adjust, you can see that its pulling a lot of fuel at idle to compensate. Perhaps play in the direct access part and lower it based on voltage. If anything, lower the deadtime at higher voltages, because your LTFT Hi is pretty good while you have lower voltages, but your LTFT Lo is terrible. Here, this maybe. https://www.dropbox.com/s/pqfgie3oew8j9ow/Bryanlogadjusted.edaAlso your ISC position is 0 at idle. Mine doesn't like the winter though and will jump around, most likely due to a bad FIAV though. Also, assuming you are still on a 16g, antilag is not going to keep that little guy's bearings happy for long.

Have you seen his deadtime settings and how low they are?
Then take a look at his LTFT Hi. The latter has only a -2.5%, but his Lo, or idle, is -12.5%. His battery voltage at idle is 14.* but his battery voltage at WOT is 12.*. So his deadtime settings at lower voltages is good, but at idle when he has more voltage, his ecu is pulling tons of fuel.
Bryan, you could try pulling a tiny bit of global fuel as both are in the negative and see how that affects things.

Ok thanks guys, I think I am going to reset SD to stock, and reset global and deadtime to what was mentioned in that thread and go from there. Guys those were the steps that I took in the summer that's why I don't understand why I have to start from scratch, also need to take care of the boost leak on the throttle body too which I don't think is helping. What are your guys thoughts on the deadtime adjustment for the injectors based on voltage? I am wondering if that should have been left alone. Stephen, I am pretty sure the wideband is good. Is there a way that I can test the injectors at home? Jroslaw if I am still struggling after a while I may just take you up on that offer. Stephan, maybe I should be looking at getting another turbo

FWIW I think Stephan's suggestion to adjust the deadtime per volt is very good. Also I wouldn't trust that link you posted for deadtimes. They show the FIC850's having less deadtime than stock DSM 450's!
It may be a long shot, but you can also try to email RC engineering with the exact injector part# you have and ask them if they have deadtime specs at various voltages for those injectors when they are used with a resistor box (not using a peak and hold driver). You may still need to tweak the deadtimes up or down, but hopefully the slope of that line will be much closer to actual.
also, theres no way to test the injectors at home, so if you can take Stephen up on the injector service for $40, its a steal. you r car will obviously be down a few days though.

Thanks Nick, I will send them an email, that would probably make my life a lot easier if I can make that happen.
Haha Stephan, I am not looking to spend that kind of money yet, I would be looking for something with similar characteristics as the 16g.
Also I seem to have forgotten what the stock deadtime is for 450s, does anyone have that?

Haha. Call me crazy, but I love turbo's that take for ever to spool but hit hard.
Hopefully they have an answer. Didn't realize before, but if its a sudden change to weird fuel trims, Stephen's probably right that something is wrong.
Is your fuel pressure normal?

Well I set the fuel pressure to 43, other than that fuel pressure seems to be working fine.

So I was just about to send the email when I found some info. RC Engineering 1000cc Low Impedance .68ms @ 13.8v @ 38psi 1.06ms @ 8.66v @ 38psi Battery voltage correction: .07ms/v .83ms @ 13.8v @ 38psi w/DSM injector resistor (6 ohms) 1.48ms @ 8.66v @ 38psi w/DSM injector resistor (6 ohms) Battery voltage correction: .13ms/v Flow rate: 981cc @ 38psi Tests on the RC 1000cc injector were performed at 38psi and with a DSM injector ballast resistor to accurately represent the injector operating environment when swapped into the DSM platform. http://forums.haltech.com/viewtopic.php?f=23&t=10407

Just an update, I spent some time working on it yesterday and spoke with jroslaw. The car will be staying as it is, I have reduced the deadtime more so that my idle is getting the correct STFT, until I replace the throttle body. After trying to set it up closer to what I had been reading the car would not warm start or idle very well. As soon as the throttle body is replaced we will be taking a stab at seeing how everything works.

This is what they sent me. I have sent them an email to ask if they have the other voltages.
