Log for 2013 camaro ss idle keeps dropping

[EdanB]

I am posting the log and the current tune on the car to see if anyone can offer any advice. Thank you for your time. Car has a stage 3 tsp cam and 660cc injectors with 1 7/8 long tube headers

have you tuned your maf & ve table yet? Fuel trims are up the shit. Double check injector settings.

Low octane spark needs addressing. Shouldn't be the same as high octane. Few other things going on with it. Who tuned it? Have you got a stock file you can attach?

[EdanB]

A tuner of my friends tuned it, but he didn't tune it properly and no matter how many times i text him he wont respond so i decided to try and attempt to fix the idle problem myself, i do not hvae a stock file unfortunately. Also I had thought the tuner tuned the maf but he didnt tune the ve table and that was the reason the idle was being wierd.

Take 5 deg out of your low octane. Get a hold of the injector data and verify. Look for a stock tune and post it up. Get into your maf and vve and you should be singing and dancing

5 degrees out of the whole table? also i have the link to the injectors i have if that will be of any use. i have found a stock tune aswell, im still trying to figure out this maf and vve tuning.

I also have the injector data but it is too large to post

Just a rough adjustment for now to keep you safe. I'd hope that you are running premium fuel (93 US / 98 Australia). It normally won't hit the numbers in the low octane table.

A link to your injectors would be good.

For your maf and ve tuning you have 3 methods to choose from.
1) maf and vve seperate
2) smokeshow maf and vve combined
3) cringer maf and vve combined

Once your injector data is verified you can go straight to work.

ooh, how does she go on cold starts? Open loop tables aren't helping

[EdanB]

on cold starts the rpms just drop and then come back, also what method do you reccomend i am new to tuning. https://fuelinjectorclinic.com/IS303-0660H that is the link to my injectors.

[EdanB]

also is there any way to tune without a wideband or should i just get one

This doesn't look like its had any VVE tuning. I'd start there after you know for sure the proper injector data was put into the tune.

Try reading about VVE tuning.

Would VVE tuning help with the idle being awful and dropping and with cold starts?
