    Lack of fuel would definitely cause it to run lean. As soon as I get my computer back, I will carefully check the spray pattern. Moates is replacing the 24 pin socket and soldering in a new 28 pin...
  2. I don't think this is part of my problem as the...

    I don't think this is part of my problem as the engine actually runs on the hot side - probably because it is mounted in a Jeep Wrangler, I live in a warm climate, and don't go 4wheel'n in the snow...

    Good point. I am running Platinum E3's (4-prongs). I will probably go back to standard AC Delco's.
  4. Hey I am providing an update. I received and...

    Hey I am providing an update. I received and installed the 1227747 ECM with the factory ASDU chip. It started right up and after a warm up period I disconnected the distributer connector and set the...

    Once I receive the ECM and its stock ASDU chip and get it installed along with a new heated O2 sensor, I will set the timing to 0 degrees (with the ECM wire disconnected). Then I will run the...

    The procedure you described is exactly what I did. The two silver marks in my picture were the piston stop points. The line I labeled TDC is the halfway point. The other wider black line is the one...

    I just did the retest, first turning the engine so top of the piston went around one full revolution before retesting the marks. Now, this comes out near perfect. It looks to me like base timing is...

    I think I maybe figured this out. The piston must be on the Exhaust/Intake stroke instead of on the Compression/Power stroke. I will retest today.

    I ordered a known good used 1224747 ECM with original factory ASDU chip (see picture below). Should arrive in a few days.

    In the meantime, I attempted to check the base timing. Originally, I...

    No air pump. I will set the base timing later today. Any suggestions on sources for purchasing an ASDU chip? I see a 1227747 ECM with ASDU chip on eBay for $85.

    I pulled the ECM and took pictures of the label and the prom itself (see attached). The BCC is an ANLW and the exact number is 86ANLW K182590103. My research says this cross references to a prom id...

    So, injectors are good. I also tested the fuel pressure at the outlet of the fuel filter and it measured 14lbs. See attached photo. Since the fuel pump is in the tank and it is a pain to get to the...

    Well, here are three photos of my injectors. One of them shows the orange and green wires and an orange marking on the front side of the first injector. The second photo clearly shows a black...

    This part number is on the injector body AC 112. Next to it is another number 17064317. However, when I search AC Delco's website, it says both numbers don't exist. See

    Fast355, I will check the timing and fuel pressure. However, I have a question about the injectors. Since this is a throttle body with two injectors, how do I tell what size they are? If I remove...

    Thanks Bob. I will look into converting to a heated O2 sensor.

    O2 is single wire (non-heated). It is located in the rear of the passenger side ceramic header (just above the collector area). Driver side exhaust connector pipe runs under oil pan to a y-collector...
  18. 5.7L running too lean (very high NOx), won't pass state emissions

    I have an 89 Jeep Wrangler with a 95 Chevy 5.7L TBI crate motor mated to a 700R4 trans. The computer (1227747), wiring harness and all sensors are out of a 92 chevy truck. Since the 700R4 is...

    I just noticed that when the engine temp is between about 125-170, the BLM is red with values in the 140s. However, once it reaches operating temperature at about 190, the BLM drops to the mid to...
  20. Thanks a million!! I now see many more...

    Thanks a million!! I now see many more parameters. It now shows the shifter position and it does go into closed loop mode. While the BLM shows 128 at idle, it goes red to 148 as soon as I go off...
  21. Missing many parameters in TunerPro RT list view

    I have a 1995 Chevy 5.7L crate motor mated to a 700R4 trans in a 1989 Jeep Wrangler. ECM (1227747), wiring harness, and all sensors are probably out of a 91 or 92 chevy truck (I didn't do the...
