E21 Project Thread - Part 2
-
Got the fuel tanks in, fuel lines replaced, battery cable ran to trunk and connected and filled with fresh gas. Turned the key for its first start, saw smoke from the engine compartment, turned key off and saw this ...
No idea why that wire fried.
-
Brian (snap) and I brained stormed for a bit and came to a conclusion that the relay I have in that spot may not be the correct relay. So, I will be getting a new relay socket this week to replace the one I have with burnt wire and also a "correct" relay. Hopefully that solves it and I can attempt to start then engine for first time.
-
I have been swamped with work and decal orders, so no time to work on this thing. Hopefully this weekend will be a different story. Brian and I are extremely certain that the wrong relay was used which had the high current positive and ground reversed compared to the correct e30 (white) relay. I have a relay coming in the mail soon and just need to make a new wire in place of the one that burnt. Crossing fingers that is it.
-
replaced the burnt wire and got the correct main relay in. turned key on and no smoke this time, good sign. went to start it, just clicked, bad sign. Brian came over to do some electrical ecu tests and all checked out except power to the fuel pump. hhmmm. fuel pump ran the first time i turned the key and relay wire smoked, but nothimg since. so now 2 issues.
i got the battery charged up at oreilly so i could rule that out. still just clicked. so i got a remote trigger starter, connected it to diagnostic port and she cranked away perfectly. heaven to my ears. now i know my ignition switch is bad and will most likely move to a pish button type ignition setup with hidden kill switch.
as for fuel pump not working, still a mystery for now. any suggestions?

Join the annoying push button start club!! Ask Brian how much he likes it

Well after some trial and error, flipping relays around and getting different injectors that DON'T leak, she lives!! Gotta keep the rpms up otherwise it dies right away, but she runs nonetheless. Having trouble with my laptop connecting to Megasquirt and tunerstudio, so haven't updated the correct tune yet. Always something!
-
Additional info for readers: tune is for 33# injectors and its running 42s.
Accusatory comment for Dave: it should really be connecting by now, are you sure your drivers arent being corrupted by downloading free Taylor Swift ringtones? You should really pay for those

Too many free tours

Still having a hell of a time getting Tunerstudio to connect to MS. It won't connect with the serial->usb cable or the bluetooth adapter. I've tried my laptop and my tablet too. Pretty annoying!
-
Stumped the efi analytics guys and also the guy who built my MS2 e30 ecu. Sending the ecu back to him today so he can examine it. Hopefully its a quick fix.

HOLY SHIT DAVE!
You've been busy in the time that I've been pretending that I don't own a project car.
I think you and I need to have a sit down talk about parts and what not.
Looks awesome man I cant wait to see videos
Thanks man! Yeah for sure. I'd be down for a little sit down talk about stuff. I am in limbo mode right now due to my megasquirt connection issues. Otherwise I am sure I would have been driving around by now.
-
That's the next step. I will try using my tablet with Bluetooth connector (tomorrow hopefully) and see what happens.
-
One floor structural adhesive and riveted down. One more to go (for now)
-
Driver side floor is done
New accelerator pedal installed
Found a source in Portugal for group 2 parts and picked up the missing link to my kit, the front airdam
Figured out the stupid connection issue and got the car running and idling on its own too.
