Good evening to all y'all,
Just finished up the install on the wideband for my newly Vorteched '03 GT, to finish up the tuning. I'm getting the car tuned by LaSota, but I wanted to come on here to try and eliminate some of these issues. Just for context, the car was exhaust leak tested and smoke tested by me before the wideband, although I should double check again. The spark plugs are gapped at ~0.30", with one step colder than stock. It has a Vortech V1 SC with a CXRacing intercooler and BOV, on an HPX blow-thru slot-style MAF, and termi injectors.
Theres a funky smell, but I think it might be the left over soldering smell, but I'm gonna double-check tomorrow to make sure it isn't electrical fire, although I didn't see anything funky. I'll try and check the grounding again.
When I first fired up the car, the car reads a stable ~22 inHg (which is good I assume) but the AFR gauge is off the f***ing wall. Like, bouncing from low 13s to high 15s. Don't know what kind of issue that is.
That is the first issue, then the SCT X4 isn't reading the voltage off of the gauge thru analog, do I wire the Firewire red to the AEM white, then the firewire blue or green to the AEM brown? I wired the blue to the brown, but I assume that's incorrect, as the voltage wasn't reading with the AEM gauge, but I still need to set up the function.
During the test drive, the boost gauge wouldn't pop above 2 PSI, but the car also wasn't pushed very hard due to my worry about the AFR. When I would step on it to try and get into open mode, the car didn't really seem to richen, maybe to like 13.00 or so, which is dangerously lean. I'm not sure how long the wideband should take to get down to where it should be, but I didn't want to fully lay into it in case of an issue. The second I'd let off, the AFR gauge would richen, like 12-10 AFR, then it would slowly climb up, until it got so lean that the gauge would give me the ---- (greater than 20 AFR). I'm pretty sure this is normal on decel, but I'm not sure.
The hot idle also has issues; once I got home after the test drive, the car will read 14.00 to 14.80 or so, and it'll stay in that zone, but every once and a while it'll jump to like 17 or basically super lean, idle will sound funny, then it'll return. The idle has always done that before the blower, but I'm not sure how to fix that, as I assumed it wasn't an issue and didn't have my hand on an AFR gauge.
hot idle
hot cruising (not sure if its problematic or not)
All in all, I'd like to have some input on what I can do moving forward, and what is an issue and what isn't. This is the first time I've done something like this to my car, and I want to be absolutely as careful as possible. I'd like to figure out as many issues as possible before I get back in there to fix the others, as time seems to be at a premium for me lately. I also attached the data logs of the car before and after the wideband install.
