Hey everyone, as per the title I’m looking at converting to TBI with a late 80s 4.3 throttle body. I see lots of good info on here and elsewhere on how to do it. My question is - should I go with a 1227747 ECM for now or jump right to a Speeduino/Megasquirt setup? A stand-alone ECU setup would be new to me but I see it as extremely usable for future performance plans and also a bit more $$$. Has anyone converted a similar engine to provide some pros and cons? I would purchase the kit pieces this summer to get ready to convert over next winter. I have some experience with HPTuners and EFILive and have access to some nice Megasquirt training videos from HP Academy.

Thanks in advance!
