Yay!!

Thank you a million times over Joe, I need to buy you a beer or a few

Not only did Joe come out to my house today to help me indentify my '92's many wiring problems, but he's going to redo my MS system and some of the wiring to components for me. This guy is professional in every way. Anyone that has to think twice about getting something done by him or has to think twice about his suggestions, needs to have their head checked! Joe is the man, plain and simple.

Edit - Anyone that wants to make their MS harness simply a DIY plug and play for '90-'93, steal the connector off a Mazda 626 from the junkyard, it's located in the center of the dash under the radio and the hvac stuff. The wiring isn't the same, but the connector on your '90-'93 plugs right in.

They both essentially do the same thing, you just don't get a fancy case and save some money w/ a DIY/prebuilt unit which can be a PnP unit as well.

I don't know how you all do it. Wiring my parallel harness and soldering all that crap took me FOREVER and I hated life for every second of it. And I'm not even that bad at soldering.

you don't think i hate life when I do it? Parallel installs eat away my testosterone.

whipping up a MS is easy compared to whipping up a parallel harness.

I'm down for that. I'm sure I could use your help when I actually get to installing my boxes of turbo stuff.

I meant injectors and I know we were getting spark because I got hit with it. Who woulda thought the spark would jump through insulated pliers and my gloves.

I'd be glad to help, I'm always looking for something to do on my weeks off.
It would be cool to have someone to help road tune as well. None of my buddies really understand what's going on, they just see they gauges on the laptop screen and say ooooooo neat

It can also cause a heart attack just so you are aware.

Granted its not as bad as getting hit by 110, but still just as dangerous.

Cute title change. And I thought there was honor among bastards...


Capt. Slow, your MS shipped out today via UPS, should be there Thursday. Tracking number is deleted so we can all track the status of your package together in collective anticipation. BTW, the beer you sent is pretty darn good. I don't buy lagers very often (they're frequently quite plain) but this one has a surprisingly malty and complex taste.


LostSoul, yours is on the bench now. Before tackling the harness, I decided to re-do all the internal wiring, as it was a bit funky. Here's how it looks now:





I installed the .1uf cap on the CAS input (it was missing) and also did the idle transistor upgrade- should help a lot from the way it was before. I was really shocked that Radio Shack actually carries TIP120s in stock. Sadly, they do not carry the mica insulators for them (WTF?) which is why it's just floating up in the air right now. Might head up early tomorrow and stop by Sarasota Electronics on my way to the meet. They close at 5, so unless I can otherwise amuse myself, I'll be at BW3 early.


Shocking news- I stopped by the Nissan dealership on my way back from Punta Gorda, and they do in fact have a load-bearing dyno. It's right next to the Hunter Hawkeye and the RoadForce balancer!!!

Turns out that Harbor Nissan actually owns a little tuning company called Relentless RPM. They're located right there in the dealership, with a little office on the showroom floor and sharing shop space with the service dept out back. I talked with Brad, the manager, for a while. Sharp guy. Turns out they started just as a way to sell chrome and bling to new car buyers, but evolved into an honest-to-gods tuner shop. Got their own fab guy, an ECU guy, the whole nut. This place may be the best kept secret in all of Charlotte county.
