Cam and ECM question...Newb to ECM's

Car is equiped w/ 165 ECM. But I would like to know if the cam I am about to purchase is "MAP sensor friendly" as I am going to either swap to a 730 or Megasquirt. Thanks in advance...Here are the specs I have for cam:

246/254 @.050 duration
.558/.558 INT/EXH Lift w/ 1.5 rockers

and 112 LSA if I recall...it is the cam in summit part number TFS-K314-500-450. Thanks for any help you can provide on what ECM I should use w/ that cam. I just don't know if it will pull a stable enough vaccum at idle for a MAP based ECU. And by that for me to get it to idle w/ a MAP based ECU.

For the most part this comes down to how good of a tuner is at the helm. I'd recommend a search on DIY PROM for 87_TA and Traxion. They are/were both running some radical SD/'730 setups. If it were myself doing the tuning I wouldn't worry about it. But I've also be at it for quite some time.
