V1 Ghostknife's #383 Track SS/SC

[Ghostknife]

Maybe I don't know the layout quiet yet but I don't show that option, this is all I have under Engine>Airflow>General

 

[Gtstorey]

There should be an advanced setting button up top.

What changes did you make to the intake when swapping into the goblin? Did the donor have a aftermarket intake that you swapped for the DF supplied one?

Yes it had a Injen aftermarket intake. I'm reading through those threads currently

Ooooh.... You just sparked a concern for me! My LSJ donor had some sort of intake on it. Should I be worried about installing the DF supplied intake arm?

If the tube size where the maf is at is a different size, the maf will need major adjustment, assuming it was properly adjusted for the aftermarket size. It probably needs minor adjustment even if it’s the same size.

Might should move this discussion to it's own post, but I came across a list of of channels to log for the LSJ. I don't haven't compared them to the ones in the file provided by jirwin.
rpm
etc%
tps%
advance
kr
iat *f
coolant *f
injector pulse ms (must record this to get duty cycle to work)
injector duty cycle %
commanded afr
wideband afr from properly transformed external input
maf sensor hz
airmass g/cyl

*if you dont have a wideband and wish to tune all events outside of PE then:

ADD:
ltft b1
stft b1

REMOVE:
wideband transformed

***you must have a wideband to tune WOT so get one asap if you dont already have one. aem eugo will work fine and wont break the bank.

You may figure out what is going on by turning back on the DTC and getting an error.

I don't know much about tuning the LSJ but the only thing that stands out to me is the fact that Dynamic Airflow is disabled. This maybe normal with tuned LSJs.

For what it's worth, mine is set to 4000 RPM disabled, and 3900 re-enable. For the most part, you want the MAF to do the work at higher RPM. Below that, the MAP sensor takes over with the VE table, which works better for transient conditions.

I'm not sure if my numbers are "right". My tune was based off a ZZP tune, so that's what they decided was right.

Well I haven't done anything on the car in a few days, the honey do list has been quite long. Been working over at the property clearing debris with the new Grappler Bucket for the tractor. Finding a spot for the forever house to go.

 

[Rttoys]

I made a grappler for my dads JD, years ago. Basically added it to his bucket. Best piece of equipment on our farm, by far.

I got the new layout and channels loaded from a post I found on the HP tuners site, specific to the LSJ. Will run a test run in the AM to see how it goes. Here is a screenshot.

 

[Ghostknife]

Took it for a spin this morning, here is the data log. Hope it works

 

[SmsDetroit]

Have you installed a stock tune to see how it would run and then compared.

 

[Gtstorey]

Have you reset the dtc to stock settings for the things that are applicable?

 

[Ghostknife]

I don’t want to do that with the 60s and 2.8”pulley. I have a funeral to go to tomorrow and I’ll reset the DTCs and rescan

 

[Gtstorey]

Something is causing it to run part of the time in open loop-fault mode. From what I can tell from researching, that is usually a problem with the o2 sensors but It's not something I know anything about. Your misfires on cylinders 1 & 4 go up when that happens.

I agree that you likely need to reset as close to stock as possible. Take your file and change everything but the fuel injector data back to stock. It should be able to run with the different pully that way. You need to stay out of WOT until this is figured out anyway. And until you get a wideband.

I guess it's normal for the LSJ to show an accelerator pedal position of way over 100%?

If this was an LNF, I would say that your MAF needs more adjustment based upon your STFT but the LSJ may be different.

 

[Ross]

My LSJ gas pedal only goes to about 92%.

My LSJ gas pedal only goes to about 92%.

I found a log on HPT forum that had way over 100% that no one commented on those values. So I thought it might be normal, although it seems unusual to me.

You can look at my logs in my build log. Still working on the tune with zzp, but it's a turbo swapped LSJ.

Ok I will make the adjustments tonight at work and upload the tune tomorrow and see how it goes. Thank you for all the information.

On the HP Tuners forum, I did find someone with a tune for 60lb injectors and a 2.9” pulley. As another option it could be worth a try since it’s close, then make adjustments from there.
