Alpine e30 progress/build thread

Probably going to have to re-adjust my picnic goal as I'll be out of town for at least 2 weekends between now and then, but I'd rather do that than cut corners to get it done. It'll be on the road this summer for sure!
My thoughts exactly. I hate rushing things and having to revisit them later. Do it right the first time I always say.

Agreed. I did a bit of rushing on some things last winter since I was hell bent on making it there, but now I'd like to take the time to fix those things and do it all right. Like last year I wired the electronic fan to be on with the ignition all the time as a quick 'get it done', which was annoying all summer, so now I'm going to re-wire it to a temp switch with a manual override like I should've in the first place.
-
interested in seeing how your manual override works. My plan is just to not overheat.
I was just planning to do a switch in the cabin in the event I want it on (like for cooling down the engine bay before working on it, waiting in an auto-x grid, etc). I have the fan running on a relay, and basically you have two switches (temp and manual toggle/latching) connected to ground in parallel that can close the relay independently of each other.
-
I just have the 2 temp fan switch. I have individual weatherpack connectors on the 91C and the 99C wires of the switch so I can experiment with both. Ideally I should just put in a manual override switch but I will save that project for another day (after I overheat).
Which fan will you be using? I am using the Spal 16" 30101517 with it wired on the high speed fan circuit

Last summer I had the deep profile/curved blade 16" Spal puller (30102049) combined with a shroud and it moved a huge amount of air. I was hoping there would be some way I could fit it and not have to buy a different fan... there is no way that's going to happen so I'll likely move to a 16" pusher (the same one as you)
-
All manual all the time for me. It’s easy to get in the habit of flipping it on and off if you’re as paranoid as I am about the temp gauge
I also drive with the heat blasting most of the summer with the sunroof cracked open

God I hated doing that on hot days when I didn't have a fan or a big enough radiator installed. Nothing better than being stuck in a hot car, on a hot day, with the heat full fucking blast.

Just remove your pants. No one will notice, and its a great way to reduce body heat.

Started making progress on the electrical/ECU side of things. I put together a bench flash harness so that I can start messing around with MS43:
I may have to make some changes/adjustments as there is a lot of conflicting information surrounding this topic, but this configuration seems to work for most people.
Basically, it consists of a 12v power supply, a female OBD2 pigtail, DME connectors 1 and 4 from the e46 engine harness that came off my motor, and a ground wire so I can get it to start in bootmode. I'll be using Galletto/JMGarageFlasher to connect to the DME and read/write partial and full flashes, and TunerPro to modify things like the redline, thermostat temps, play with fueling/cam timing, etc.. I didn't have a T15 torx screwdriver at home last night to remove the motherboard so I'm hoping to connect it up and give it a shot tonight.
Side note, I came across a good deal on a set of genuine BBS gold/blue center caps to replace the roundel center caps on my wheels! They have a really nice metallic blue background that looks almost black in low light and an awesome bright blue color in the sun.

They are retro and beautiful! -
those centercaps look fantastic.
roundels for sell?

Probably! I was going to hang onto them in case I wanted to switch in-between the two, but once I popped the new ones in I doubt I'll ever do that haha.

MS43 bench flash update!
Initially I was having problems getting anything to connect. I forgot to connect pin 4 of the female OBD2 plug (chassis ground) to ground on my harness so I corrected that, and with the help of some fantastic documentation on the ms43wiki, I used a hex editor to modify Galletto to accept the FTDI chip serial number of my USB to OBD2 cable. I am now able to connect to the ECU to Galletto and read the 64kb 'tune' files. I also brought the newly pulled files into TunerPro to poke around, but the XDF I am using is written for MS430056 and my ecu is currently MS430066 so none of the values align or make sense.
The EWS delete tune that I will be using is a full 512kb flash of the ECU that will also change it to version 0056. This full flash needs to be done in JMGarageFlasher, as Galletto cannot do the full 512kb files as far as I know. So far, I have not been able to get the program to connect at all. I believe at least part of the problem is the USB to OBD2 cable I am using, so I have ordered another that people seem to have had success with. That should come in sometime next week so we'll see if that makes a difference.

With the new cable I was able to connect to the ECU in boot mode on JMGarageFlasher without any issues and read the full (512kb) file. Once I had a copy of the original software, I did a full write with the new MS430056 software from "daniel f." on e46fanatics/MS43wiki that has both EWS and checksum CHK5 disabled! Once that process was complete, I connected the ECU via Galletto and read the new partial flash, pulled it into TunerPro:
The software now shows up as version 0056 instead of the original 0066, meaning the flash was a success!! This is big progress towards getting this on the road. With this basic EWS delete the m54 should be able start, idle, and rev to a limited 5500rpm, which is all I need at this point.
I will, however, get a whole slew of trouble codes and errors, one of them being a 5500rpm 'limp mode' caused by a missing speed sensor signal. I can use TunerPro to remove this limiter (or get the ECU to accept the e30 speed sensor signal), as well as disable any unnecessary DTC's, force emissions readiness, etc. I'll only want to start messing with this after I get the car running though, that way I can eliminate screwing up the ECU if/when I'm trouble shooting.
