Nasty Electrical Problem...Need help ASAP!!!
Moderators: I know this doesn't really belong in here, but there are a bunch of bright guys that lurk here, and not the other forums. That, and i really need help with this.
Here is the scenario:
My car is a 95 LS-SE, which used to be turbo (sorry guys, it had to go), but i traded it for a b18c1 swap. I've had the swap in for about 1 week, and have been running off of the LS ECU with no prob. However, 4 nights ago some a**holes tried to steal my car. In the process of stealing it, they tried to punch the ignition, broke the ignition cylinder, ripped my alarm out, ripped some relay out from under the dash, stole my ECU, ripped the maint req box out, and generally wreaked havoc to the interior of my car.
So today i get my hands on a P72 ECU, so i can take adv. of the b18c1.
I got the car started, and it throws code 23, like it should, cause the wires for vtec haven't been run yet. However, this is where things get nasty.
The car will barely start, when it does, it has a hard time idling. At idle the tach will bounce from 750rpm to 8k and bounce all over the place. The speedo will do the same. The car will also intermitently cut out. This is all with no extra throttle input on my part. While driving, and holding the car steady at like 60mph or 3k in 5th, the tach will jump to 9k-7k-2k-6k-0 and eventually cut out. The speedo will also show random mph at idle. Now, this almost has to be electrical, cause the engine doesn't rev to 8k and such at idle, just the tach/speedo goes wild.
Any ideas? TPS? VSS?

Re: Nasty Electrical Problem...Need help ASAP!!! (Tomakit)
I had electrical problems in my ITR before. It was the O2 sensor power wire grounding to my exhaust pipe, causing the speedometer needle to fly up and down. There is definitely a short somewhere in your car. Check the speedometer fuse, and see what other circuits run off of it. Check the power and grounds on those components (I know for sure the 2nd O2 and Speedo are on the same fuse). The maintainence required box shouldn't be caushing your problems, but you did say they ripped out relays. Check that all the connections are good. Also, alarm wires: make sure that nothing is exposed. If 1 of those wires ground out when it's not supposed to, it can shut the car off. There's a good chance that your problems are there. Hope that helps.

Re: Nasty Electrical Problem...Need help ASAP!!! (Incognito)
tomakit did you fix all the wires/relay and other such items? i know you have an integra but i had to move a wire on my swap for the secondaries and add the wire for the knock sensor.
check the pin diagrams for your car vs the gsr motor.
you coud also have a bum ecu but not very likely. id start looking at the wiring they messed up 1st.
