Alpine e30 progress/build thread

I had a free Saturday morning over the long weekend to clean my garage and work on a few little loose ends with the car. 

 

- Coolant leak seems to be sealed up finally, at least so far.

- I have functioning brake lights again after bending the switch bracket a bit to make sure it gets better contact against the pedal.

- New front wheel bearings made a world of difference, they must've been a lot more worn out than I thought. 

 

I left the exhaust alone for now because I want to drive the dang thing. It is now doing daily duty for the next week or two to get everything broken in and start sorting out the minor details!

How are the daily duties going??

Loving it! I really missed driving this car but the downtime has been worth it so far. There are definitely some kinks to work out and minor changes to make but the extra power and torque have really upped the smile factor in everyday driving. I've been easing into beating on it a bit now that the clutch has some miles on it too. The rear tires definitely aren't going to as long as before haha. I had to switch back to the wagon for the last few days because I needed the bike rack though.

pssh, have you seen my e30 with 2 kayaks, 1 bike and 10 fishing poles on the roof?

Haha I've seen a picture or two of the two kayaks, who needs a truck! My excuse is laziness... I actually have a Thule rack for the e30 from back when I bought the car, but the only roof tray I have that holds my mountain bike is bolted to the wagon at the moment.

I picked up another ms43 ecu to start messing around with (in case I brick one). I did a full firmware flash to delete EWS/checksums and set it up to run an M54B30 to match exactly what the current one is set up as initially.

I then started messing around with TunerPro and RomRaider (there are really nice ms430056 definition files for each). I have been getting a P0444 (Evaporative Emission Control System Purge Control Valve Circuit Open) and P1112 (Engine Coolant Temperature Radiator Outlet Sensor High Input) code every time I start the car, which makes sense because I don't have either of those things anymore. I was able to suppress the DTC's for those two systems and now my ultragauge shows 0 trouble codes! I'm sure it's throwing many, many more but they will only show up in something like INPA so they're less of a priority. 

I also started messing around with the electronic thermostat temperature maps to try and bring down the peak operating temps a bit. Right now it runs between 197-206F and I'd like to shift that range down slightly to 190-200 or so. I lowered the peak values in the AC on and off maps, as well as the initial value before it reaches the oil temperature threshold, but didn't see a corresponding change when driving the car, so I'll have to investigate further and try some things. I might have to lower the actual oil temperature threshold to force it into the main coolant temperature maps sooner.
