Initial thoughts from Maximum PSI is that it's a defective regulator. We're trying to figure out how to get the car to the shop at this point. They are trying to get a replacement regulator at this time.

I will update here when I know more.

I talked with Mike today and Aeromotive is shipping me the missing piece, as well as a new plug for the fuel pressure gauge port. We think that things simply aren't tightened up enough.

The plan is to fix it this weekend hopefully, and then that should be good. Even so, I will be sending it back to them to triple check things after.

I received the parts from Aeromotive. Unfortunately this did not resolve the issue.

The car is being picked up @ 7 AM and being towed to Maximum PSI, where this will hopefully be rectified for good.

So it turns out that it would have resolved the issue, had I executed the repair correctly. The car was flat-bedded to Maximum PSI this morning, is repaired, and is being verified for a day or two before I take it back.

Fuel is still good.

I recently did one of the 3M headlight repair kit, worked pretty well. Didn't plan on using it, but that's another story.

Fueling is still a bit off, a bit too lean it seems, however, the upside is that the OBD checks all went to OK, so I can get my car inspected shortly. Then I have a year to get this all sorted.

Car has passed inspection. I need to replace some tail light bulbs, but minor stuff.

I'm almost done with the wiring harness design for the Motec integration.

I'm going to follow-up with Nick and Mike about the DME calibration. I may switch it to the Motec for now because I know that is not as lean.

Rear bulbs replaced.

I had the low coolant light come on a few times - never seen that before, and I don't see a level sensor in the wiring diagram...not sure how it detects it.

I bought some coolant (Prestone Long Life 50/50) and will top it off tomorrow when cold.

Check if the colour of your coolant is blue. I generally don't like to mix the glycol stuff (Prestone) with OEM BMW coolant. Nothing wrong with Prestone though....I've got that in my 330i.

Coolant sensor is on the bottom of the coolant reservoir. (Where the filler cap is)

I could not tell from looking what color it was.
What I do know, is adding the difference between the bottom and top level points brought down temperatures by about 10 degrees C! I was seeing up to 105 degrees C last night ~68 degree F ambient. Today at in the high 70s, the max I've seen so far is 99, averaging 94. So, don't ignore a low coolant warning. Also I'm not concerned about the small amount I mixed in. I will likely have a full flush done soon anyway.

Where is that sensor in the wiring diagram?

Stick to the blue BMW coolant. The aluminum and plastic parts look notably better on cars running the oem coolant vs the green stuff.

Lovely. Well, the difference I put in shouldn't hurt anything, right? Or should I have you do cooling system maintenance earlier then planned?

On another note, moving injector timing to 360 degrees BTDC has resolved the 5% difference I was seeing. Steady-state is near dead-on (+-2%), so transient fueling tuning is next.

If you need a little more umph at the pressure plate, have you considered installing a resistor on the signal wire for the hydraulic pressure? while playing with my ssg, I used a resistance wheel to manipulate the signal while watching the results in inpa. May be a good option if your not 100% happy with it at the moment?

I'm not sure if it needs more oomph - it seems to be an issue where the transmission _thinks_ the clutch is engaged, when it's still engaging...so grinding gears results. This happened even on the DME. However, the DME is running too lean...and the Motec is running too rich during transitions...so I need to get transient fueling closer with the Motec before drawing any conclusions.

Just a suggestion, if you have inpa, check the clutch position with ignition on, engine off. I can explain in relation to the reading you have, if it is an issue.

Well, that's going to take a back seat for a second.
I think either my harness is finally giving me trouble, or I did something incredibly stupid with the transient fueling. Under anything other then light load, the car will buck and go super rich. I hooked the DME back up, and it's exactly as it was before, so I know the car itself is OK.

I'm going to take this time between now and my harness being made to get the DME sorted, and clean up the integration work that I've done so far. Now that we have a cruise control module available to us, I should try and get the steering wheel settings correct, so Adam and I can actually use cruise control even under the M150.

I also have started re-purposing the ProEFI 52mm CAN Display:

CAN Miniview Debug by mattdrobnak, on Flickr

That is clearly not powered by ProEFI.

So while this weekend did not turn out perfect, at least some progress is being made.

Quickly making progress:


However, it's getting late, so that's probably as far as I will get tonight. I'm switching between "Matt was here" and Lambda in this. I need to clear the display, clearly.

Nice work ... Makes me think of the many late nights I have. I love this flux capacitor stuff

That is awesome, and clearly illustrates the power of the Motec system. I know of very few systems that give you the tools to write your own CAN code. (Bosch Motorsport, and McLaren are the only ones that come to mind)

Splash screen and real data!



Sorry for the camera position, I don't have anything to put the gauge in.

However, the value of this gauge just went from garbage (even the new ProEFI firmware does not support it) to quite valuable. It's a lot cheaper then other options, and I have not even started messing with the input buttons. For now this will end up replacing the eBoost2 inside the car. The solenoid that came with the eBoost2 will be driven by the MoTeC.

Updates:
I'm now getting a brake light signal fault between the EGS and the DME. The only thing actually connected to the Motec is X60004, which has the CAN bus in it.
I also did something dumb some time ago when I replaced the passenger side bulb in the headlight - I did not put it back in correctly...and I ended up melting the socket.
Thankfully, jack.chris328 here had a reasonably priced set of Xenons, so I am upgrading this weekend.

I plan on taking the time to isolate the M1 completely for a few minutes (everything unhooked) and seeing if the brake light signal fault goes away, and if so, plugging power back in (and forcing the O2 sensor to turn on after 30 seconds), and seeing if things are still OK. If so, I will leave the M1 offline for some time in this way until I get the harness done. If it does not change, then I have to figure out what the heck has happened with my car. :-/

Always an adventure. Sometimes frustrating. Sometimes exciting.
