Round 3....another M3 build

[hinrichs]

Only update, took the car to my local shop yesterday.

[hinrichs]

So finally got the OEM sensors....which arent cheap....and guess what....nothing changed.

Really starting to get to the point of giving up and selling this car. Maybe ill just get a loan like I should have and build another e46 or something newer.

Thanks!

Searching for name of those rims, can you help?

Millie Miglia, I forget which model they are, but I actually still have that set which never sold.

You're seriously replacing the whole harness? Why not just locate the issue with a multi-meter and repair it for a fraction of the cost and time.

I already did the engine harness as it was only $250 and the one I ended up with is in much better shape anyway. I figured the issue was in the rats nest of wires that is in the middle of the harness so out it went....best part is it solved nothing

From more reading and reading and reading, everyone says you have to use oem sensors on these cars and that nothing else works, so I will be ordering them up today and hoping for the best.

Got my new tune thursday last week, swapped the ecu out, still having the same issue (hoping it was a fried connection), so I ordered up a new engine harness since we both think its somehow a wiring issue somewhere since its throwing a hard code as soon as you turn the key. That will be here tomorrow so time to pull the intake off once again. Also needed to order one new fuel injector since I broke one of the plastic ends over the weekend putting it back together again after trying to find a broken wire.

My girlfriend helped me finally bolt in the cage this weekend. I felt like an idiot having to run to get bolts 2 times since I couldn't seem to count correctly, but its in. Still need to figure out the back sides of the seat trim tho, since I want to put it back in and make it look factory since this time around I want to keep the back seats in for sound deadening. Also this car I think is only going to be autocrossed so I dont need to strip it out. Even if I do go to the hill climb eventually, I want to be in the street class which would need a full interior basically.

Also just for fun, I placed in one of my stashed away old style Sparco seat belts. Its only a simple 4 point and of course I have one blue, and one black, but the stock seats dont look terrible with them. I know schroth makes a quick fit option, but not sure how it works with a harness bar like I have now. I have some plans on seats, just need to figure out which way I want to go. Main issue is my girlfriend fitting in a passenger seat haha.

If it runs good without a tps maybe it's because it goes into open loop that way? That would mean it could also be maf or o2 sensors instead. Maybe try unpluging the maf instead of the tps to see if it acts the same way.

I keep getting a TPS fault code, so I think its something with the DME not actually recognizing the sensor properly. If I unplug the maf it shuts right off which when I read up it will run on either the maf or tps if one isnt working.

Keep at it bro! Love the work you have done so far. Stay strong, when it's working it will all be worth it

Thanks, I hope I can get it going soon.


So over the weekend I ended up just working on my tool boxes more...finding out how many sockets I have lost over the years is annoying but of course I have extras of all the ones that I didnt loose. I did however get these throttle cable bushings installed (ended up deleting cruise control in the process). Both bushings were shot anyway so I was thinking just maybe, that extra slop was messing something up. Also thew in the cage....yeah its staying black till winter when I pull it and get it powdered coated. I didnt bolt it in yet but its there. Have yet to drive the car.

Hopefully friday I can get the car up to a shop an hour away to try and figure some stuff out as well as tune it for whats been done so far.

Last night I installed the headlights, and broke one of them already (well the sidemarker tab) so I am pissed about that. Also did an oil change and it was just black with no signs of coolant.

1.Not really sure yet, last car I just left it black and it was boring. I was thinking red or something but thats kind of boring as well. Good thing as any color works well with silver. Thinking whatever it ends up being I will get whatever wheels I pick matched to the cage.

2.Yes original(and new) sensor, and also stock throttle body. The intake manifold I swapped is from an older m50 which is obd1 and flows better.

you need to get it diagnosed, was it acting up before the manifold swap?

[hinrichs]

aside from the bad luck youve had with this one i like the direction, love the cage and that oldschool steering wheel

2 questions

1.) what colour you painting the cage?

2.) did you have to use the original sensor and throttlebody when you swapped inlet? or is it all built in? (im not a bmw guy so dont ****)
