p1170/0172 and c1201
Hey y'all, I've been problem free for quite some time and loving my SC. Yesterday morning it threw ALL the CELs at me.
Backstory; Edelbrocks initial CARB tune caused my LTFT to max out. After a full removal, inspection, reinstall, and 6 cigars worth of smoke testing, it turned out it was their tune not playing nice with the 2017 ECU, and they sent me a bespoke tune to fix it. Worked great, but pretty nasty mid band drop. SOOO three weeks ago I bought the Edelbrock tune from Delicious Tuning. Smoother power delivery, but I think less HP overall, no dyno proof. Before changing the tune the car got a full service at 56k, to include spark plugs (I want to shoot the engineer...) I noticed a week ago a 2k hang during start up, had to tap the gas to get it to go down, but our temperature and humidity had spiked so I shrugged it off. Yesterday, at around 1/4 tank I drove to a riverside location and did some hiking. When I started the car I got the CEL, TC light, and cruise control light orange. Used the ECUTek and pulled P0172 P1170 and C1201. My intent is to contact DT, and I know there are some prior DT guys in here that might be able to guide me, but I'm not really sure what the issue is. I'm pretty upset that I dropped $450 for a tune that isn't jiving with my car. And I kinda doubt that I suddenly blew a vacuum line outta nowhere. I've seen that the bypass valve is often the issue, but if anyone has a test procedure that would be helpful. I'm also wondering if bad fuel would cause this. (No I didn't put in 87 by accident or something, but the fuel stations I'm around are... well they don't have my full confidence.) Anything else I should be looking at?
