IAT and wideband problems
 

Ok so i installed a mspnp and here is what i did so far:

-installed gm iat and lc-1 wideband
-reflashed firmware for w/o maf
-connected lc-1 to number 10 pin on mspnp center connector
-cut stock narrowband wire to ecu
-re-calibrated both lc-1 outputs to 0-5v .5-1.5 lambda
-set tunerstudio project to lc-1 defaut
-copied inc files into tunerstudio project folder

So my db-9 wideband gauge reads correctly but i don't get anything on the tunerstudio gauge. Also, my iat stays constant at 26 degrees, independent of the outside temperature. The car does start and idle. Thanks for any help troubleshooting this problem.

Check the connection on the IAT. Also note that pin 10 is the second from the left, looking into the connector - ignore the little numbers molded into the connector; we originally designed it with a connector that didn't have them there...

I always get confused as to which way your looking at the connector. Here is how I connected it

I was afraid of that - connect it on the other side.

Thanks, I changed that last night and now the wideband works. Didn't have time to mess with the IAT connections. Can i test the connections for the IAT sensor with a voltmeter? What values would be reasonable?

Matt - you say other side. Which direction? Upper pinouts or opposite side, same slots (lower pinouts)
And being a 12 slot pinout - how is 10 one slot from the end? That would mean 11 - right?
This is why I need to know top / bottom when viewing this and number sequence.
Thanks.

Lower pinouts, opposite side.

Okay. So how is thing numbered? I need pinout 8 it seems for the MSPnP.

I see where it states "Top pins 1-6 / left to right..."
How do you identify which is the top or bottom?

****Edit*** Got it! Thanks Ben!
