I am setting up for Speed Density. I am using the plug and play SD harness from MAF plug to a GM 4 bar map and GM IAT. The IAT reads -40 all the time. Has anyone ever experienced this?

Here is the latest log. Cranks, starts to fire, then dies. I added about everything to the logged data list.

It's a fully built 2.3 long rod stroker. I will try these things tomorrow. Thank you!

Ok. I think I have the sensors logging now. Also turned on o2 simulator. This latest logshows a rough start, idle ok, then increses in rpm then dies. Will not restart.

Starts rough, then idles. Runs very rich. Will rev only if I ease into the throttle. Quick throttle bogs and stalls.

It's been awhile. I hope you are still around v8s_are_slow. I have a datalog that I need some help on. Hope you can help.

I did all of this and still no start. Do you mind looking at my latest log?

I have lc1 assigned to front 02 since there isnt a "wideband" option. IAT and map are plugged into a speed density quick harness, so I am not sure what to assign where.

The LC2 is not listed as an option for a wideband in pic assignment page.

Here is a log when it was running.

I finished my DSMLink last night and was able to start the car. It was running very rich so I quit for the night. I made some changes to try to see other data to be displayed. I'm not sure what I did, but now the car wont start.I think I changed pin locations, but can't remember.Car info...
