My wife's 2016 sonic started having problems with the intake cam phaser and I told her that fixing the issue might become quite expensive. Talking about parts here since I'm fixing it myself whenever there's enough money to spend on it. I managed to fix both intake and exhaust cams to 0? and the weird noises when cranking the engine went away. Now here goes the fun part, I currently have not disabled the variable camshaft option from the Airflow>variable camshaft> camshafts. Apart from taking vvt from the airflow portion of the engine, how should I aproach the new "temporary" method of the engine breathing air without the vvt sytem working. Sould there be a spark readjustment, VE tables adjustment? I'll share my current tune and a log from a couple hours ago from today along with the original tune.
Any ideas and recomendations would be greatly appreciated, as Im only having this mod in the ecu meanwhile I get enough money to fix it properly.
Should be able to turn off the VVT and not have to make any other adjustments. With the cams stuck at the home position you'll notice reduced performance at the higher RPMs and maybe reduced mileage if you do lots of highway driving, but nothing drastic.
Curious what your MAF is reading? Noticed your cylinder airmass is pegged around 2160 mg which also seems very high for a 1.8L (I'm seeing ~800'ish mg max at WOT on my 3.6L with aftermarket cams). Also see you're getting a lot of knock - perhaps try reducing spark (high octane table) in these areas and see if the knock reduces/goes away.
Also see your fuel trims are often off by 10% or more - could use a tune Tuning the air models (MAF and VVE) to dial in the fueling should be done with the cams parked as far as I know since you can only adjust the base VVE table (both cams at 0); easiest way to do this is dial in the MAF first, then compare MAF airflow to "VE Airflow" (PID 2311) and adjust the VVE cells by the % difference between the MAF and VE airflows.
