Diary of a Madman; TitaniumTT's see you @ DGRRXI RE-REbuild

[TitaniumTT]

I'm going with the MoTeC traction control Multiplexer, the TCMux. With the M"hundred series" you can wire the signals directly to the ECU IFF they are hall effect signals. If they're a mag signal like the stock ABS system is, they need to be converted to a Hall Effect signal. MoTeC has the converters, one per axle. In my case though, I have 4 digital inputs, right now one is wheel speed off the driveshaft, one is low sump, and the other low 2-stroke. Becuase I don't want to give up the low level warnings (I could with a simple LED light, but want them to trigger an RPM limit if they do go off) I needed the TCMux. It takes all the signals and converts them to a coded signal that the ECU sees. From that it gets wheel speed, both driven and rolling, calculates slip, and activates or doesn't activate the traction control.

The Traction Control itself can be setup anyway you want it to. Ignition retard, fuel cut, hard cut, boost dump etc etc. In our case, can't really use ignition retard becuase it'll melt turbo's, fuel cut is a bad idea, hard cut can get dangerous so I'll be using the boost dump. I suspect that the boost dump won't do everthing that I want it to. So I may be changing to a DBW which is definately the way to go. The ECU senses the slip and backs the throttle off for you. Can't get much better than that.

The problem that us rotary guys have is the way the earlier MOP's work, it's a feedback system (which is better than the renni's non-feedback system) and the ECU just doesn't have the outputs to run two basic DBW systems. So if I do go the DBW route, I may need to get MoTeC's DBW-4 which is a CAN commincation setup, or ditch my MOP and run a DBW setup and save whatever the DBW-4 expense is. But this is next winter stuff

I will tell you now though that the FD will be a DBW system, and I won't be running the OMP on that motor, so I'll probably ditch the OMP on the FC as well.

As long as you're using the factory jack on the pinch welds you're good to go. The factory jack doesn't put any weight on the seems, it uses the seems to keep it from slipping off. It's when shops use them for lifts, and home guys use their floor jacks that you run into problems like the disaster that I'm dealing with. I'm actually heading outside shortly to get back at the FC. Undercarriage is completely clean so it's time to flip her over and strip all the harnesses out, then wash the underside..... and the floors after I'm done

64 days....... wow.... need to stay busy

Got a bunch more done tonight and we've turned the corner. Everything has been stripped and cleaned. I'm hoping that the repairs will be done by the end of the weekend and the herculiner will be on too. I think that's a little ambitious but we'll see.

So the FC is shiny side up again but man is she looking bare. The only things left on the car are the woper motor, the MoTeC and the fuel filter
