Default MAP sensor LS7/MSD intake?

Using the GM LS7 harness/ecm designed for LS7 crate engines with an MSD intake. The recommended sensor is #12615801. I believe that is for the stock intake which uses a different mounting scheme. The MSD uses a SCHS to secure the sensor.


I see several sensors that mount like that, but not sure what is the right choice.


Anyone have a recommendation?


thanks.

I went through the same problem looking for a bolt on sensor that would fit. Got the ls3 sensor which has a bolt hole in it but its in the wrong place and a bigger vacuum stem that wouldn't fit into the MSD as delivered. Wound up using an LS1 sensor that normally snaps into place and used a locktited bolt and washer to hold it in place, no problems. You'll just need to make sure your harness plugs into the LS1 sensor okay. I had a truck harness and it plugged in fine. You might look at an LS7 sensor, I didn't, if it fits the MSD and the harness use a bolt and washer th hold it in place.

Can you post up the part number for the map sensor you used on your MSD Atomic?

I'll go take a look in the shop first thing in the morning. I thought I had the receipt here in the house, but apparently not. I'll get back to you shortly...

Part # 12644569
63011


This one does not have the molded round feature for mounting with the small screw, but works just fine with the screw if you use a washer.


There is a part # with the round feature, but I think it has been replaced with this one.
