1). Any boost, vac, or exhaust leaks?
Vacuum and exhaust good visibly good, tight and all new. I don't have a boost leak tester.
2). Verified mechanical timing?
Yes
3). Verified base timing?
Verified CAS but i cant get idling long enough to set ignition timing.
4). Ignition system
COP or Stock Coil: Stock
Wire brand and Age: Oreillys 1 year
Spark Plug brand, type and Gap: NGK-BPR7ES/set to recommended factory gap
5). Motor health (Compression Test)
Not very relevant to my issue IMO, but i'll do one tomorrow and check plugs.
Cylinder 1:
Cylinder 2:
Cylinder 3:
Cylinder 4:
6). Performed basic throttle body adjustments?
Idle Switch: Deleted? simulated thru ECMLink
Throttle Cable: Custom cable, but throttle fully closed with no gas applied.
TPS: Yes
BISS: S90 throttlebody
7). Compression ratio
7.8:1
8). Any known bad sensors or brittle wiring?
No
9). Any DTC/CEL codes?
No
10). Electrical system
Car off (not running): 12.2 volts
Car running: 14.3 volts
11). Base fuel pressure and injector values
Base Fuel Pressure: 37
Injector Size (cc/min): FIC 650cc
12). Properly calibrated and configured wideband sensor
Sensor Brand: PLX hooked to EGR pin 15, narrowband sim thru LINK and set to MISC egr for plx wideband
Calibration Date: ??
13). Type of fuel
Type: 92 Octane
Percent of Ethanol: 10% i believe
14). Watched ECMlink how-to videos?
Yes years ago, they don't seem to be available anymore.
Well, I've got my 1g started up finally, and my wideband wired in.
I believe I've got everything hooked up proper in V3 ECMLink.
I can't get the car to go into closed loop, or to stay running during idle. It will slowly lean out and lose RPM and die.
**I havent been able to set ignition timing, because I cant keep it idling**
Attached a few logs.
I tried lowering the deadtime, and increasing the lower hz values in MAFComp. (seemed to help) it idles higher and smoother at first.
S90 throttle body
-everything but TPS deleted
SMIM
650 FIC (30.9% global fuel) started at 210 deadtime
PLX wideband to EGR input, using 0-5v wideband and ECMLink narrowband sim. set to egr input
Fuel pressure MT 37 PSI
Any advice on how to get it into closed loop would be great. And also how to keep it running long enough to even go into closed loop!
When I rev it, she loves it and has 10-12 AFRs. I also saw the Front o2 finally move from .2v to .8v with a decent rev.
