I've put an LQ9 LS 6.0 in my 99 S10 and I'm using the 6243 PCM that has been programmed for the LQ9. Everywhere I read about getting the 99 S10 tach to work the posts say to set the tach output with HPTuners to CRANK and 3/3. I get the 3/3 part, but the only choices I'm offered for tach type is 12V pullup or no pullup. Where do I find the choices between frequency and crank?
I understand the signal from the pcm may be too weak for the tach and I'll need to add 12v and a resistor, but that's a different issue.
