Please review this tune CTS-V tune or toon?

[matthewallison85]

2012 CTSV LS7 90mm TB, FIC 1000cc injectors, 2.38 pulley, Speed Engineering exhaust no cats to Magnaflow mufflers, Btr3 cam 231/248 .617"/.595", DSX Aux PUMP, E85 sensor. please take a look at this tune any advise would be greatly appreciated as I just received HP Tuners yesterday. I'm simply asking for pointers as sometimes my car stalls and dies while coasting to a stop.
Thanks.

if you car stalls and dies and you only have pulley and injectors you tune is not setup right

[GHuggins]

This tune isn't making any sense to me at all. MAF isn't tuned in the lower cells even though it's pullied - going to flow more air at idle just as it will in the higher rpms. RPM, Minimum idle airflow, adaptive idle, decel airflow for trans - all altered - sure there isn't a cam in this thing? Only reason for altering these to this extent??? Didn't look anything else over, but O2 position settings weren't touched either for the headers, but it is pullied so could inadvertently cancel that part out.. Injector settings were changed - didn't verify correct settings.

This thing does have a btr 3 cam. Sorry I left that out. Thanks for the input.

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.

It runs good just sometimes it dies coasting to a stop. But it’s like one time a week it will stall. Not other than that it runs well I had it at the track and it ran 10.9 @ 126mph

[matthewallison85]

I have yet to install my AFR gauge. But will do logs after installation

[SultanHassanMasTuning]

you need to be more specific on the brand of the injector

cam specs as well
intake size
headers
free flowing or catted

The cam is a btr stage 3 cam for the lsa motor
Speed engineering headers and exhaust no cats
The intake is airade intake with green filter
90mm throttle body
Dsx aux fuel pump.
I have hooked up the wide band and I’m capable of doing data logs now but it’s raining here. I do appreciate your input and help guys. I will post some logs this weekend.

3/4 race cam yee haw

p.s. When someone asks for cam specs they mean duration, lift, lobe separation, at the very minimum. BTR has more than one "Stage 3" (*spit*) PDS cam for LSA/LS9.

[PGA2B]

3.38 pulley

Do you mean 2.38 pulley?

[matthewallison85]

Do you mean 2.38 pulley?

Yes 2.38 pulley.
And as far as cam specs I?m looking for the cam card.

I bumped the in gear ideal up a bit seems to have helped. I mads a a small log hopefully I'm doing this correctly?? Its raining here so longer logs to come this weekend. any advise would be greatly appreciated thankslog 1 ctsv.hpl.Disabled 7.5 CTSV MAF EQ ER 12.30.21.hptat4.hpl


new data and tune am i on the right track?

[SultanHassanMasTuning]

what brand of injectors?

data in file shows 1050x

can you confirm

[matthewallison85]

The injectors are F.I.C 1000cc

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

[dhoagland]

Assuming these are the injectors you have, your data is different.
Did you get a sheet with your injectors? (In case I downloaded the wrong sheet, this is from Fuel Injector Clinic NOT Fuel Injector connection).

The whole sheet was too big to upload, here is the flow rate page only

[SultanHassanMasTuning]

if its fuel injector connection gonna have a hard time
