I'm going to try to get this done as short as possible. I'm running a b16a2 with a p30 (obd1) ecu. I've recently dropped another b16 in and everything was fine for a while. I did a minor tune up and trying to start the car, a wire arched and almost caught on fire. I fixed that, my speedometer (especially at higher rpms) just goes ape ****. I replaced the cluster and now it still does it but only slightly. On the old one it would actually cut my fuel off to the engine. There are a few other electrical issues, and the car at one point in time took on some water (not a flood) but the car carries moisture in it and I think that might be part of the problem. I want to get a new ecu and rewire the car (paying someone to do the work) Can i change my ecu completly to obd 2? Guess of the cost? Ty in advance. Also would it be worth it to get MSD ignition in the same job?

Have you checked for blown fuses under the hood and dash? For example, is dash fuse 15 blown?

I've check a few when something else happened and nothing was blown. Everything works, just sometimes it gets screwey. For example my tach w/light is set to light up at 7k rpm. When it hits like 4.5k the shift light starts to light up but never fully brightens unless i keep the rpms going up. If i lower or raise the rpm the shift light is supposed to go off at it either is brighter or not on. Like if i put it to 9k it's off until i hit like 5.5, if i put it down to 6k the light is all the way on at 3k rpms. I dont see a fuse causing an issue like that.
