So, I got this car from a guy who built it and got sick of it, I'm finally trying to get it right, (the car has mostly sat in a garage) and I'm not too sure where to start. the car had the aem wb and truboost hooked up, and boosts to about 18 psi in 3rd with the truboost on Hi. Buuut...He didn't even have the wb set up in ecm link as a wb, and had a bunch of fuel pulled out on the fuel tab, and mafcomp has been adjusted. It has always had a CEL at full boost above 5k in 3rd and 4th, which I now know to be knock. I got the stupid AEM setup, I think...That's question one - if my RawLinWB and my LinearWB overlay perfectly, that means it's calibrated, right? Question Two: Is there any way to figure out with link what these "Mystery Injectors" are, or can I at least dial them in without knowing the type? Is this knock a result of bad Global fuel settings for my injectors? Question Three: Should I get rid of his fuel slider/mafcomp settings and start fresh? (Do you adjust mafcomp with a stock unhacked maf?) Are these fuel settings why I'm seeing knock? My WB says 9:1 when I get knock, ? And finally, Question Four: I'm planning on going SD anyway, would it be easier to just start there? Or do I want to get this dialed in to help setup my VE tables? I guess that's more than four questions, but w/e. If it'll help I got a pic of the injectors, but they're pretty nondescript, with no markings on a black cylinder. 03 Pull is idle, 08 is a long on with a 3rd pull and a 5th pull, showing a bunch of knock. Feel free to ridicule me, I'm a newb.
Ok, here is this part:
1). Any boost, vac, or exhaust leaks?
No
Boost leak tested 5psi above your max boost with no leaks?
Yes
2). Verified mechanical timing?
Yes
3). Verified base timing?
Just bought a timing light, will update in like 30 minutes.
4). Ignition system
COP or Stock Coil: COP
Wire brand and Age: SparkTech
Spark Plug brand, type and Gap: NGK-BPR7ES/.026
5). Motor health (Compression Test)
Haven't done recently, need compression tester - but should be good, bottom end is supposed to be @20k old
6). Performed basic throttle body adjustments?
Idle Switch: Simulated via link
Throttle Cable: Yes
TPS: Yes and did the calibration in link after warm up
BISS: Yes
7). Compression ratio
stock
8). Any known bad sensors or brittle wiring?
No
9). Any DTC/CEL codes?
Knock
10). Electrical system
No multimeter, I'll buy one if you guys need this. My stereo and lights work fine.
11). Base fuel pressure and injector values
Base Fuel Pressure: 43.5
Injector Size (cc/min): "750" ish
12). Properly calibrated and configured wideband sensor
Sensor Brand: AEM
Calibration Date: 4/12/19
13). Type of fuel
Type: 91 Octane
Percent of Ethanol: 0%
14). Watched ECMlink how-to videos?
Yes. So many I've come full circle to confused again.
