i need some direction

[davispaintandbody]

im learning to tune just for the fun of it.
i got a17 ss camaro and here is what i bolted on so far

-lt4 injectors
-2" LT headers
-3" cat delete x pipe

i need some direction on what areas do i copy from zl1 and what areas do i leave stock

i love playing with my car i just dont want to blow it up lol

here is my tune and a logg

Don’t copy anything from a ZL1 file other then injector data... that’s an expensive toy to learn to tune with..

A boosted low CR engine is vastly different then a high CR NA engine

[TriPinTaZ]

What other upgrades did you do to the fuel system to be able to support the injectors?

Also, yeah.....this isn't an easy platform to learn to tune on.

just the injectors

its all i got to play wth

Your low side and high side will need to be replaced with LT4 parts as well or the injector upgrade is useless.

what about the settings for the lt4 s/c

[Ben Charles]

what about the settings for the lt4 s/c

I would not use 90% of the settings due to what I’ve mentioned prior... although similarities in CI and head flow, it’s not a good idea to use the Lt4 file as a start point

[davispaintandbody]

what about map characteristic's ?

[davispaintandbody]

do i need to calibrate the maf to zl1 columns and then copy orver the settings ?

[kevin87turbot]

As mentioned, this one is a difficult one to learn on. If you have the LT4 MAF and tube, then you'll want to start with that as your MAF calibration. You'll have to spend some time on the VVE cal...the LT4 VVE won't be applicable.

That being said, I'd recommend that you pay someone like Ben to at least get you a base tune file. It would be money well spent.

i have the lt4 cai but am using the lt1 maf so i tuned it to lt1 columns and its a little better
the problem is there is no pedal till about 2000 rpms

[Ben Charles]

The MAF sensors are the same… quit copying and start tuning

[TriPinTaZ]

None of this matters unless you have a low side solution(at least an LT4 intake or DSX) and also the LT4 HPFP or the Big bore. You won't have enough fuel with stock LT1 fuel system and LT4 injectors.

bingo

[davispaintandbody]

ben charles told me in a email that with my current boltons i would be fine to run 575 rwhp

not the same when tuning because the columns are different but i think you know that

[mJolnir]

Go to the gen 3 and gen4 sections, search the "how to tune using the stft+ltft method" thread, this will get you started, the only thing you will use from the zl1 file is the injector data, i also recomend you buying a wideband, AEM 30-0334 is what i prefer.

You can change the columns on any gen 5 program… depending tube size I always adjust this for maximum resolution

i had bad throttle response before i changed all the columns over to exact math to lt1. now it revs up fast maybe to fast
