Tpi Air Flow Meter Question
I have seen a different air flow meter in 1993/1997 TPI Camaro/Trans Am's than in the 1989 Trans Am's.
Does anyone know if one can swap the newer , shorter air flow meter into the older TPI's?
It seems that the newer air flow meter is about half the length of the older "Bosch" style meter.
Thanks!

In a word. No.

In more than one word? Any details that you can share?

The TPI MAF sends an analog voltage signal (0-5VDC) to the ECM to indicate air flow. The LT1 MAF sends variable frequency signal (0-10KHz) to the PCM to indicate intake air flow.
There was a company offering a device called the "MAF Translator" that allowed the use of the later MAF in the TPI systems. It was basically a D/A signal converter. They were about $179 the last I saw them. You can get a complete new MAF for that much.
