Newbie question , re; mem-cal compatability; TBI to MPFI ??

[romac55]

Need an info byte or 2 ; I have 2 ECM's , both #16197427 , from different fuel systems , one MPFI , the other TBI . Will moving the mem-cal from the TBI unit to the MPFI unit be successful ? I'm installing an M20 Muncie in my 55 Chevy and the engine is from a 95 Astro V6 Vortec with MPFI and auto trans , so I need to modify the mem-cal to lose the auto trans inputs . I'm figuring just a mem-cal swap should get me closer , then do a tune from there ; does that sound reasonable ? I'm ordering the Moates hardware to tune it anyways , but thought this might be a bit more my speed , as long as the TBI chip will work with MPFI . It doesn't sense fuel pressures , and they're both the same year ECM's , just wondering.....Be safe...Bob.
