Thanks 93 and sixshooter ; I'm trying to ask about just switching mem-cals from auto to manual . I originally named my system MPFI , but what I've learned so far is , it's called CPI here . Okay , I've got a 95 Astro 4.3 Vortec engine with CPI and 16197427 ECM ; can I just switch chips from auto to manual trans , and would a manual trans TBI chip work to run my TPI ? Are the TBI and TPI manual chips interchangeable ? Be safe...Bob.
You've got me completely confused? I've got to go for this evening, I'll check back tomorrow.
