Look in our <a href="https://www.thirdgen.org/newdesign/tech">Tech Section</a>.

I believe Mauro's TBI to TPI article is in there. Yep, it is, I just checked

 

thanks dirk ..i missed it
btw great to see you back online

 

i found the article however it is tbi to map tpi ...can maf tpi work on 1991 and keep all other accessories working ...ie speedo ???

 

What exactly did you buy? Did you purchase a harness already, ECM, PROM??
If you just bought the intake set up, might want to think about going with speed density anyway. It would be easy to convert if you didn't already buy the harness and computer related stuff.
Let me know and we'll go from there

1991 Z28, 305TPI, 5-speed,
AS&M ported & polished intake, AS&M polished LTRs, AS&M port matched plenum, TPIS 52mm TB, Richmond 3.73s, SSM SFCs, SLP LCAs, SLP panhard, ATR 3" exhaust, MSD 6al, Taylor 10mm wires, SLP PROM, and a host of other stuff.

 

the tpi i bought was from a 1986 corvette
consists of
harness
ecm / prom
runners
manifold
all associated sensors that where attached to the motor a brand new maf sensor
the auto kickdown cable
+ other stuff that i dont need (serpentine belt setup ,alternater etcetcetc
it was everything that was bolted to the motor because the motor was ending up in a hotrod with carb

 

I just completed a similar swap and I am very pleased with how it turned out, will be glad to offer any help/suggestions you may need.
