1997 Speed Density PCM - Tuning Forum

Well I had the pleasure of downloading the VCM out of a 1997 Cavalier, LD9 5spd.... and the results are in - it's ALSO speed density.
I am beginning to think that 1997's were speed density and GM switched to Alpha - N in 1998. It explains why the S-AFC worked half decently on his car...
One thing to note.... the timing maps are all far more aggressive on his setup than on my 1998 pcm and the 1999, 2000, 2001 and 2002 LD9 pcm's I have downloaded... quite interesting.
So now that I have one registered, once HPT gets back to me I do believe I'm going to drop this into my car with a 2 bar.

Slowly but surely may some day win this race...
Oh the things GM does....lol
Best of luck with it!
Well, this is interesting. I stripped a 97 w/ 2.2 last year and kept the pcm to experiment with when the new engine's together. Sounds like I may have gotten lucky and picked the right year.

not all 97's are speed density my 97 auto is alpha-n i wish it was so i wouldnt have to use more credits to flash to speed density
I would love to find a 97 auto 2.4 cav or sun with speed density.

How would someone tell if their 97 was speed density or Alpha-n ??
how the tables are listed in HPT.
MAP VS RPM, or TPS VS RPM.

Thought I saw something on techline / TIS saying SPS wouldn't allow you to flash to an older cal anymore. Is there a way around this?
-->Slow
if the tech. is savie, or if the TEC-II has the call in it already, you can get it. my TEC-II's have the GM charger CAL, in it because of me, when i got the kit back in 2003.
i guess you could always copy a cal with HPT and pass it around?

Probably won't know whithout looking at it with HPT. Seems the LD9's are hit and miss.
