Got the backup. Exact DME cost $80 online. Will update when it comes in. The read went smoothly. Took about 30 mins from opening the K-Tag box to a successful backup.

 

This looks promising. Anything new?

 

The replacement DME comes in today & I will flash this afternoon. The backup was pretty easy, however, I'm wondering if I need to do anything else. The information available online is pretty much all over the place on this when it comes to VIN numbers and other items. I'll know this evening.

 

I think you need to get the EEprom of the ECU. it contains the vin and security code (ISN number). the flash is the software to process the inputs and outputs of the engine. the eeprom is 64kb.

 

It pulled the EEPROM and MAPS. No flash was present, but it pulled a file for that as well. I did two pulls. One consolidated and one split to verify size.

 

Got you...when I used FG galetto, it would fail on the "maps". The eeprom is the heart of the ecu.

 

ITS ALIVE!!!

I do have three errors.

1. P053A
2. P0193
3, P0102 (

DME came last night at 9:30(!) from UPS. I flashed it at lunch and put it in the car. Started right up. Car is in "reduced power" mode, but I think I got too excited and didn't tighten a hose down (bog down on initial throttle & The powers up). I didn't have too much time to troubleshoot, but I will tonight. The good news is that it runs!

 

 

Big thanks man! I can't believe it was that easy and sooo much cheaper than Mini or the mail in service.

 

Any time brother....I went through this process with close to 4 times and each time was $300. Until I decided to do some more research and trail and error...no one is willing to share the "secret" because there is money to be made with this service.

 

I'm hoping that with Manic dead someone will let the cat out of the bag on OBD2 N18 tuning...

 

I know there are quite a few tuning files surfing the net and I know Dr. Gene (the software) is used for tuning the files. I personally haven't tried that yet since I'm waiting for a worthy mini to be tuned. I'm eying a flooded R61 next week hopefully i get it for a good price

 

So the P053A was my bad. Those little connectors on the intake hose from the turbo (mini c clamp 2 prong connectors) were not seated in fully. Now I am just getting MAF (P0100 & P0102) and Fuel Rail Pressure Sensor Circuit High (P0193) failures. The P0193 is causing the engine malfunction message. I checked the rail pressure reading through the OBDII and I am showing 3624.5 psi. The MAF flow rate is at 39.8 lb/min. I am getting a lot of fuel burning through, guessing from the smell. I'm guessing that the MAF failure is coming from excess fuel burning through the system. Am I off on this assumption? Any ideas?

 

did you have these issues with the old ECU before it died?

Sometimes the donor ECU, depending on the condition of the car it was removed from, might be damaged! before you waste brain cells, verify the donor car was not hit from the front and wires were not cut/shorted due to an accident. Also verify the pins of the ECU are not bent.

 

Maybe a slight fender bender. Checked the pins initially, everything looked good.

 

Reached out to the seller of the DME I flashed & they sent me more pics. The accident looks bad, however, no major damage to the engine bay. So I cleaned everything up and I am still getting the following codes. P0193. P0100. P0102. The engine is running in reduced power mode. I've cleared the codes and they always come back. A P0136 and P0141 pop up for a little bit, but cleared and haven't come back. I have a spare O2 sensor so I will be changing it out tomorrow to see if anything changes. The O2 sensor was coming up before the original DME fried, but not errors with the FRP sensor or the MAF. I also cleaned the MAF with MAF cleaner and checked for any vacuum leaks. Nothing looked bad. Ran the car around the block and it runs smooth besides the reduced power. No stalling or misfires. Also, took some snapshots of sensors through the OBD2 tool I use. The thing that concerns me is the FRP sensor still reads very high.

 

try to disconnect the HPFP to see if the pressure changes. just to confirm, the DME has the exact numbers? because in the second half of 2012 the HPFP changed to bosch and the pin assignment on the DME aslo changed.

 

One thing I hate about this car, I have to be careful ordering parts because of this 12/13 crap. Thermostat housing was a nightmare.

Yep, EXACTLY the same DME. How should I disconnect the HPFP? Any specific connector?

 

there is a connector right above one of the thermostat pipes towards the back. that is the HPFP quantity control valve.

 

So disconnected the connector. Value didn't change. That's not good is it?

 

do you know for fact that your HPFP is good? do you get a new code?

 

I really don't know if the HPFP is bad. It was never an issue we've had before. The codes do not change with the connector disconnected. I disconnected the other connector as well to double check. No code changes. I cleared the codes, tried again, same three codes, P0100, P0102, and P0193. It just does the same thing & wreaks of fuel smell (no leaks).

 

what is the ECU p/n?

can you disconnect the FRP sensor? and see is anything changes.

 

Same three codes. P0100 P0102 & P0193. OBDII shows the same pressure, 3426.5 constantly.

 

Time for another ECU...
