So doing an sr swap on my 240. First problem was I wasn't getting fuel prime now I fixed that but now I'm not getting spark I checked the CAS and the timing is all good but then I took an extra look at the ecu and saw this... Are those tabs important is there a fix or no I need a whole new ecu? Where can I buy one from a trust worthy person

unless they are stopping the plug from fully seating they are not the problem or issue.
open the ecu up, look and smell. check the plug side for pushed out pins. go through the wiring again. make friends with people, borrow an ecu. if this is your first swap you probably missed the coil pack and/or head ground.

As long as the harness fits snug you should be fine

Thanks for the reply I'll check the ground again on the coil packs, and make sure my harness is as snug as possible. my brother has an ecu for his black top s13 sr20 I have red top. Is it safe to try his?

If he has an e5 or e6, should work fine, but definitely if you're just verifying spark.
