I just got my DD2000 the other day and have put together a few combos with pretty good success, but I have just "guessed" as to what some of the terms meant. Can you define some for me such as:

1. Piston Down Bore @TDC. Is that how far the Piston is down form the deck of the block at TDC? Also, how can I calculate the PDB?

2. IVO (BTDC)

3. EVO (BBDC0

4. ICA (ATDC)

5. IVC (ABDC)

6. EVC (ATDC)

7. ECA (BTDC)

8. IVO

9. EVO

10. ICA

11. IVC

12. EVC

13. ECA

I know these may be fairly simple questions and may be noobie-ish, but I am new to the program and any help would be greatly appreciated. graemlins/beers.gif Also, if you don't want to answer all of them, just a few would be helpful. Thanks in advance,
Chris

well im gunna give this a shot., if im wrong then, sorry.

1. Piston Down Bore @TDC. Is that how far the Piston is down form the deck of the block at TDC? Also, how can I calculate the PDB? i have no idea, havnt figured it out myself

2. IVO (BTDC) Intake Valve Open (Before Top Dead Center)

3. EVO (BBDC) Exhaust Valve Open (Before Botton Dead Center)

4. ICA (ATDC) I have no idea

5. IVC (ABDC) Intake Valve Closed (After bottom Dead Center)

6. EVC (ATDC) Exhaust Valve Closed (At Top Dead Center)

7. ECA (BTDC) Umm, nope dont know

8. IVO Intake Valve Open

9. EVO Exhaust Valve Open

10. ICA dont know again

11. IVC Intake Valve Closed

12. EVC Exhaust Valve Closed

13. ECA

Thanks a lot Aaron!

no problem. i have been messing with dd2000 for a few years. its awesome. im pretty sure thats what those mean, it only makes sense for the prgram. but like i said, if im wrong, sorry.
