Please review this tune CTS-V tune or toon?

[matthewallison85]

what brand of injectors?

data in file shows 1050x

can you confirm

Fuel injector clinic. Sorry I didn?t think there was more than one FIC injectors

Okay
Did they send you a data file with the injectors? The file I downloaded is different...
I would hate for you to change the data unless you are 100% sure its correct. If you know who entered the data into your tune you might want to see where it came from..

OK, well that's kind of worse then. None of the VE was tuned. None of the lower MAF curve was tuned. Does it stumble any at all performing a wot stomp from a dead stop by chance? Almost feel like it's misfiring at times? Just going off of the timing curve for that... Is this a final tune or just a temporary?

I would really like to see a log with as many channels as possible.

Not to steal any attention away from the original thread but I've been reading for a couple days trying to diagnose my Vs issue with a misfire like stumble accelerating more aggressively from a stop or even from a lower speed trying to get up in traffic. The car will only do this until about 3k rpm and then it smooths out. I had assumed the MAF curve was wonky and I did pull the tune that is currently in the car but I would really like to get it running correctly for the mods it does have.
-Brand new LSA blower sent off to Kong for porting during
build
-DMS reinforced brick
-NW 102MM TB
-Air raid Intake with 6? Green Filter
-2.3/9.1 pulleys
-BTR Stage 2 Cam (87k miles)
-New Lifters (87k miles)
-.660 springs
-DSX Aux Kit
-ID1050s w/Flex Sensor
-New Oil Pump during build (40-50psi idle, 30-35)
-ARP head studs
-Longtubes, Catless X pipe
-Corsa Sport w/magnaflow resonators
-8gal Trunk Tank
-EMP Pump
-1? lines for heat exchanger setup
-Vadder Dual Heat Exchangers

Any advice is appreciated. I would even be willing to set up some histograms from calibrating the maf with a little help.

If I'm reading this correctly. You have set the Tune for Open Loop MAF only and you are adjusting your MAF Air Flow table based an error log?

The logs seem to show you are heading in the right direction.
But until you know if your Injector data is correct it is kind of a wasted effort (not saying its off I haven't looked at it, just going off replies here)

Not sure if this matters, but you might want to read your FPCM so people can see how it is setup with your added DSX pump.
I notice in your logs a lot of time you are commanding 50 PSI. Not familiar with CTSV at all maybe this is normal and seems to follow your low flow mode in Fuel System tab

His tune isn't setup for OL may only...if you go to Fuel>oxgen sensors>ECT vs. startup ect that temp is set to 102 degrees.....so above that and the car will be in CL. His LTFT are disabled so the car will be running on STFTs only, which is fine

Changed some of your injector data, it seemed to be wrong (ECM12307, 12315, 12303), and couple other things. Just do a compare, to see a difference. Might give you some idea of what to mess with.
Your VE table is odd ~1800 - 3400 rpm, looks like it was just smoothed out.
Do a log on your MAF as well, to see where you are at. With injector changes it will most likely be off.

Forgot PE and Flex.
You should change PE to something similar, to get into it faster.

his VVE table is actually stock which from what I've read will cause drivability issues when cammed

[Ethan5.019]

@mememe123
So they didn't update all the injector data for the ID1050s? Do anyone have an injector data sheet or know where I can get one so I can update this before I start looking into the maf? I built a channel config and a layout for the car so I can log it once I correct the information.

[mememe123]

The ones I put in there are from my tune, I have a '14 V with ID1050x.
ID have injector data on their website, free of charge

[Ethan5.019]

@mememe123
I appreciate that. I have the ID1050 on my ODIN charged F150 just wasn't certain if I could use the sheet that came with them for this application. I'll make the necessary changes and actually run a log in a few minutes.

This... VVE becomes critical on LSA's even with just a pulley change.

It's funny you say that being that a performance shop did all the work and even dynoed the car after they did the upgrades. I've owned the car maybe 6 months but I knew something wasn't right just from the little I've driven it and finally had time to pull the file and start getting answers.

post a log and mark where you feel the problems.

Here is a log of just very normal driving. I couldn't get my EQ Err Ratio graph to plot any data so I'm still trying to fight that but I am logging the MAF Freq so I'm not sure why it didn't work. This log is before any changes were made to injector data.

[mememe123]

I can post some channels/configs when I get home, if you need them. You just gonna have to add your own WB02.

Remember if you are in CL to use your NB 02 sensors for fuel corrections and not your wideband. You will need to force the car into OL to use the WB for fueling corrections

Mark a time where it happens so I can save time reviewing it

[Ethan5.019]

@Alvin
I will get a better log of the problem area tomorrow weather permitting. Today's log I couldn't get into the throttle and make the car act up. I will also adjust my histogram and graph so I can use the STFTs to calibrate the MAF since this car does not yet have a WB O2 sensor.

[GHuggins]

Usually when these start sputtering after a cam install the timing is too low - you do have a little odd timing table and could probably add some more in the lower rpms. However being that your VE wasn't tuned, I would look there first. Plus brand (x) injectors usually use different inj data than the regular non (x) injectors, so keep that in mind when looking up the correct data for yours.

[Ethan5.019]

@GHuggins

I just finished changing the injector data and setting the tune up for MAF tuning. I also corrected my histograms to plot STFT vs MAF Freq. I will probably flash this sometime over the weekend and get some good logs in so I can better display what the car is doing in the situation I'm concerned with. Is there a good thread to help me with the VE tuning once I get the MAF pretty close to where it should be?
