If my DSM isn't running next week, getting a Honda, please help me!

Alright, long story short, driving one day, CEL, burnt up ISC driver on ECU, car won't idle. Don't know if it's from broken ISC or leaked capasitor, don't care, I bought a new ECU and ISC anyways. Put in new ECU with old ISC disconnected (haven't gotten new one yet), still won't idle, though ECU is still fine (I'm pretty sure). So when I do put in my new ISC, I'm guessing I have to do this crap below to run smooth again:

--------------------------------------------------------------------------------

1g Idle & Timing Adjustment STRAIGHT FROM DSM MANUAL...

- Reset ECU 15 Minutes to clear all the crap out.

- With car off
- Ground that pin on the Diagnostic Connector
- Fully warm car up, No accessories on.
- Run at 2500 rpm more than 5 seconds
- Let idle for 2 minutes
- Adjust BISS 700-750 rpm
- Cut car off
-Disconnect Jumper at Diag Conn

- With Car OFF
- Connect Timing Jumper
- Fully warm up car - No accessories
- Check CURB IDLE is at 750 + or - 100 rpm (may take a little while to settle down being you just reset BISS)
- Set Timing at 5BTDC (which means you'd see 4 IMO due to bad angle)
- Cut Car OFF
- Disconnect Timing Jumper
- Cut car ON
- Check Basic Engine Timing 8BTDC (kinda jumps from 7-9 usually).

- AFTER setting Base Timing correctly per the above you could then "bump up" Base Idle a little (50 - 100 rpm) to help with the Fan cut-on - The ECU can pull more than you can retard! - Some of us have BOTH Fans cutting on simultaneously so that is loading your Alt more than a stock setup - Typically you can retard one degree when setting Base Timing & it idles smoother as long as Idle is close to spec - Setting it where you see 4 will make it more resistant to losing RPM when fans cut on.

--------------------------------------------------------------------------------------------------------

Now, could some one please break this down for me. I don't get what half of that means. I have a manual, but am having trouble finding this stuff. Please no abbriviations, and tell me what each step involves, where to find the things I'm working with (Like what they are, where they are on the car, how I adjust them, etc.) and what I exactly need to perform these steps (like grounding stuff, do I need some wires or what, or do I just ground something that already exists on my car). I'm so confused at this point, that I am getting sick of DSM. I only bought one because it was a good deal, and I my civic had a bad paint job, and lots of other little things that bugged me. But if I can't get this crap figured out, I'm goning with a prelude, integra, civic, 240sx, whatever (I mean, I won't be losing much, I don't have a turbo like most of the people on this site anyways). So please, can someone help me out with detail please. Thank you in advance.

Thanks a lot. That should help me out some, but what about the second part of what I posted. With all the stuff about adjusting the timing and whatnot. Will I need to do that or just mess with the BISS. And will I be able to tell pretty easily if my FIAV is messed up when I take off the ISC? Will there be coolant in there, or something to indicated that it's messed up? Thanks.

The second part is to adjust the TIMING. Since you just replaced the ISC, you only need to adjust the IDLE, which was the link that I have you. As for the FIAV, try this link http://www.dsm.org/how-tos/tttt/tttt3.html

Well, I got the new (re-manufactured) ECU in, the new ISC in, did the above BISS thing, and wouldn't you know it, my car is running again. Wooo freakin' hooo! 320 bucks poorer, but oh well. And I also found out my intake was sitting on my a/c line and had been wearing it down. Good thing I found that (although in the only place I could think to put it now, it kinda hits the hood I think so I'll have to put some foam there or something). I also took the intake silencer out while I had the intake out to let the INJEN pur a little nicer. Thanks for all the help. Guess I won't be needing a Honda right now, but I still might put my car up for trades on craigslist to see what I can get for it because I really miss driving a 5 speed. Later homies.
