why can't the speed density TPI computer work? there is no MAF in either case.

Tas, that is a really good question. I wish I knew. Maybe someone here can enlighten us.

Look further down the board. I believe Kevins dad recently ran a TBI with a TPI computer, although I'm not sure whether it was MAF or SD. If I remember correctly they had mixed results with it. I'll see if I can find that post...

 

Found it! It was speed density. Here's the post: https://www.thirdgen.org/messgboard/...ML/000505.html

 

hmm. my next project should be doing the TPI computer swap and throw 8 injectors on a Torquer 2 intake.

 

Or you cpould just keep your TBI computer, get the Edelbrock harness (TBI to MPFI 8 injector splice-in-harness, $35?) from Howell and use your TBI unit (without injectors) as the air control device. This way, all the idle control/air control stuff is all done. All you should have to do to get you in the ballpark is change the BPW on the PROM to match the MPFI injector size you are gonna use... WEIAND make MPFI conversion manifolds, by the way, for a pretty decent price and you can get rail/regulator kits, too. Just trying to make it easy to try/tune. I'm gonna try this later but no motivation until salt/sand is off the roads for the Winter...
