Another reason to do a Auto to Manual tranny swap

I have a 1990 Vert manual, my friend has a 1990 Vert automatic. Quick reference for those that don't know, smog fails in Cali are primarily due to excess Hydrocarbons (HC) ppm.

We both took our Verts for smog check to different places albeit on the same day. His automatic measured 66 HC's at 15 MPH and 47 HC's at 25 MHP. Maximum on the print out was 118 HC's at 15 MPH and 93 HC's at 25 MHP, so of course he passed.

Here's the interesting part.

I measured 96 HC's at 15 MHP and 65 HC's at 25 MHP, so you'd think I also passed right?

Nope.

Max for my manual Vert was 83HC's at 15 MHP and 65HC's at 25 MPH. Talking to the smog tech, apparently the standards differ between Auto's and Manuals.

Where I'm going is that since the only way the smog computer knows what you have is by the VIN, you apparently have the best of both worlds (easier HC standards and joy of manual shifting) with a swapped 2nd Gen.
