Has anybody here tried a newer style MAF with a TPI? Would there be any benefit for power or driveability? I would think they have got to be easier to find and probably less expensive....and certainly more reliable.

 

Really, nobody has tried this or even thought about doing it?

 

Are you refering to the '90+ speed density MAP system or the later LS1 MAF?
Not sure, but I'd think LS1 MAF would not be a direct fit in literal terms, or with the ecm.

 

No, i am not referring to the speed density setup. I am curious if any newer style MAFs would work with TPI. I looked at wirirng diagrams today at work and found that TPI MAFs are 5 wire while a 96 and 00 f-body MAFs are both 3wire sensors. The TPI uses 2 grounds, burnoff power, 12v power and 5volt signal and the 96/00 had 1ground, 12volt + and 5volt signal. So I'm thinking maybe a 93 or 94 sensor might work. If I remember right 93&94 still used proms so they would be the most likely to be compatible. I am asking about this because my MAF died and the local GM dealer wants $850 new and 360 for reman, which is on backorder. I got a new gm maf for my truck last year for 180, so I have a hard time paying over $300 for a tpi maf.

 

I just got done installing a BlowerWorks http://www.blowerworks.net/ MAF 3" unit in my 85 Vette, it uses RTD digital electrics. These guys really did a good job for me and I have never had better performance from my engine.
