Folks-
I've been troubleshooting problems with my 5.7 V8 swap into my 89 S10 Blazer. It's out of a 89 C21500, in front of a 700R4, I have the proper ECU (1227747) out of a similar application.
I recently extended my harness to reattach the VSS as the swap and some harness rerouting required it. I'm not getting VSS data in my log, and I'm thinking that has to figure into the air/fuel tables.
Logs are attached- took a trip to the grocery store 10 minutes away. It's a cold start to the grocery store, then a warm start back. I think my idle is a bit low (it registered 525 at times) and it does appear to vary (I figure this is IAC at work). Otherwise I think my data looks pretty good overall.
My (quite possibly very wrong) take from this:
-Vacuum looks great. It ranges between 15-24"
-TPSvolt appears high at idle, but linear. I need to adjust the sensor.
-INT, BLM, MAP- I need to learn about them.
-Truck is rich on accel, I'm thinking that may be as designed.
-BPW MS.... err, what?!!
-O2 sensor volt is crazy high. 872v? I'm thinking no.
-IAC appears fine.
-knock count is 81 in a 10 minute drive. Is this excessive? I know it's more important to see when they occur, but if it's not excessive why worry?.
