Guys,

I finally have the car up and idling. Problem I have now is I can't gt my idle under 1200-1100. Looking for the proper table for thi, just not sure? The only way I can get the idle down is using the VCM scanner, On/Off controls, clicking on Special, set the Steps to 50 and click on the step button. I know I'm changing the IAC position, just don't know wher to adjust this for good.

Also the car is on blocks, bu the speedometer in the scanner reads 7-10mph? Not sure what is causing this?

I've attached the bin & log. Thanks in advance for the help.

Type of car, mods and any other info would help.

Have you done a idle config on the car yet?

Did you clear your fuel trims(in the VCM controls)? If the PCM is reading MPH then it is not in is going to be in idle tuning. You have your B2 sensor about maxed out and not switching.

Engine is in am 85 Camaro
60ln Inj
2-bar MAP OS
Mild cam, TFS heads
Vortech SQ (no belt yet, so no boost)

No sure what you mean by an Idle config?
I have set idle airflow, some idle VE tuning, idle rpm,idle spark.
Trying to get my idle correct for now.

What brand injectors? Stock cube LS1? What is your fuel pressure?

How do you clear the fuel trims? I noticed that B2 sensor was maxed out, not sure what to look for there. Also thinking of unplugging the VSS to see if the scanner will show 0mph instead of 7-10mph.

Siemens Deka 60lb. Fuel pressure is at 45psi, using a fuel regulator so the INJ constant is set that way in the PCM. 383 cu

I would force open loop for now to get the car running and to start working the VE. Your injector info also looks a little off. The BE (boost enrichment, under fuel/power enrich) is set at 1.0 which is 14.7 in boost so you definetly wan't to fix that before driving it.

Fuel trims is on the VCM scanner under controls/fuel spark then reset trims.

I would start with forcing open loop.

How is the throttle body getting its air now? Do you have all of the plumbing to the superchatger connected?

Yes the supercharger is all hooked up. I guess I can disconnect it for now & have the throttle body open. Running a MAP anyway. I'll try to reset the trims etc in the scanner & re test. Will that make B2 sensor re trim? Wondering why it's maxed out?

Your fuel trims are maxed out commanding it.

Many thanks Mustangbrk02,
Things look good now. Ready to continue to tune.

Anyone have any ideas on the MPH sitting still? I unlpugged the VVS sensor & the PCM read 0mph now. Is the sensor bad, or picking up some sort of interference?

Are the vss wires ran by any other wires? We had this problem on my little bro's truck we swapped a 5.3l into and it was doing the high fluttering idle similar to yours. He had his vss wires ran close to others and was getting the interference showing he was going like 10mph at a stand still.

What type of transmission?

ostrich

Yes, the wires are in the harness along with the rest. I made a new harness for my installation. It's an M6.

Wondering if I should just run 2 separate wires down to the VSS. Shouldn't be too hard to do.

May be braid them as well to help?
