OK so installed cold ecu car fires up 20 times swap back to hot ecu car floods wont start swap back cold ecu car starts fine engine hot soon as cold ecu get warn i get the same problem 2 bad ecu wtf ebay that explains why the last ecu i got from ebay had some chip that looked after market and the tabs looked pride open and for the orinal ecu i think i screwed it up for forgeting to shut off the key a couple times over night must have fried the resisters cuz my icv was stuck like it had heat froze ...

Change or check youheadtemp sendor, and check cold cranking volt to ensure they are the same as hot cranking volts to eliminate the volt issue...

JohnS | problem sloved switched ecu with customers car starts up fine hot or cold and no more check engine light .. i could never get the ecu to disple 1444 it seems to be perfect i was getting code 1211 witch was ecu malfunction on both ecu's and with miler chip and ostrich all this time i thought the 1211 code was because of the chip not comunicating up to speed with the ecu ... from what miller told me . two bad ecu's from ebay wtf is the chace of the happing no wonder they where only 70 bucks hahahah stupid me!!!!! thanks for all your help john at lest i got all new parts to match my new motor.. | | | 04-20-2011, 09:06 PM | #19 | Senior Member Join Date: Feb 2009 Location: san jose Posts: 425 | spoke to soon tried my ecu's in other car ran's good this can mean only one thing car is to rich at hot start its not cold start sensor that's new so i guess i really need to work on idle fuel setting's and low tps setting maybe even play with idle timming ... | | | 04-21-2011, 10:35 PM | #20 | Senior Member Join Date: Dec 2007 Location: Gulfport, Florida Posts: 3,208 | Quote: Originally Posted by blowin 4 spoke to soon tried my ecu's in other car ran's good this can mean only one thing car is to rich at hot start its not cold start sensor that's new so i guess i really need to work on idle fuel setting's and low tps setting maybe even play with idle timming ... | The head temp sensor controls both cold and hot fuel enrichment during starting. If the sensor is bad it will be good for cold starts and inject too much fuel during a hot start. I hate to keep harping on this but the head temp sendor will cause this exact issue | | | 04-21-2011, 10:51 PM | #21 | Senior Member Join Date: Feb 2009 Location: san jose Posts: 425 | i have a new sensor i even put the old one back tested both so far i have 15 hrs of tryin to get this car to tune at idle and not flood even straced the wires to the ecu pulled my injector rial cranked over car injectors shot gas like a rain fall i have to pull the fuel relay just to get it started ..it idles good not rich and if i go to the software shut down the injectors they still pulse at start up .when i install ware chip it will start 7 out of 10 times but will still flood but not as bad . barrie says i have a bad laptop cause i cant get trace to work and we both ttied reinstalling the software i give up putting it back to stock and see if that problem gos away.. | | | 04-21-2011, 11:20 PM | #22 | Senior Member Join Date: Dec 2007 Location: Gulfport, Florida Posts: 3,208 | Quote: Originally Posted by blowin 4 i have a new sensor i even put the old one back tested both so far i have 15 hrs of tryin to get this car to tune at idle and not flood even straced the wires to the ecu pulled my injector rial cranked over car injectors shot gas like a rain fall i have to pull the fuel relay just to get it started ..it idles good not rich and if i go to the software shut down the injectors they still pulse at start up .when i install ware chip it will start 7 out of 10 times but will still flood but not as bad . barrie says i have a bad laptop cause i cant get trace to work and we both ttied reinstalling the software i give up putting it back to stock and see if that problem gos away.. | Your laptop is most likely all jacked up with issues which I have problems doing remote work or logging when they are like this. If you need a clean one I can send one to you for a deposit and you pay shipping both ways. This Laptop will be fresh with only INPA, ELM-232 and other BMW diag tools on it including teamviewer. John S Let me know ***Better yet take your lap top in and get it cleaned.Remove all bots, spyware,etc and have the registry fixed. Should cost less then $70if it is real jacked up. Would be cheaper then shipping mine and yours would be fixed. Computers need to be cleaned and invalid reg entries deleted about every 6 months sometimes sooner if you're surfing pron like I do daily. It's not a twinkie and will last for 20 years it needs to be serviced Last edited by xxxJohnBoyxxx; 04-21-2011 at 11:31 PM. | | | 04-21-2011, 11:50 PM | #23 | Senior Member Join Date: Feb 2009 Location: san jose Posts: 425 | Quote: Originally Posted by blowin 4 i have a new sensor i even put the old one back tested both so far i have 15 hrs of tryin to get this car to tune at idle and not flood even straced the wires to the ecu pulled my injector rial cranked over car injectors shot gas like a rain fall i have to pull the fuel relay just to get it started ..it idles good not rich and if i go to the software shut down the injectors they still pulse at start up .when i install ware chip it will start 7 out of 10 times but will still flood but not as bad . barrie says i have a bad laptop cause i cant get trace to work and we both ttied reinstalling the software i give up putting it back to stock and see if that problem gos away.. | just put my stock injectors and afm car couldnt have ran any better .. im going to try in tune it with stock afm if it works good by maf ...my main problem it that theres no way to adjust start injector pulse ...car idles great pulls like crazy just that flood problem when hot. | | | 04-22-2011, 12:24 AM | #24 | Senior Member Join Date: Dec 2007 Location: Gulfport, Florida Posts: 3,208 | Quote: Originally Posted by blowin 4 just put my stock injectors and afm car couldnt have ran any better .. im going to try in tune it with stock afm if it works good by maf ...my main problem it that theres no way to adjust start injector pulse ...car idles great pulls like crazy just that flood problem when hot. | That flood issue needs to be tuned out of your tune or you have a bad head temp sensor. It's that simple. Inpa or ELM will tell you if you have the temp sensor issue. If the sensor is good then you have a tune issue. I think it is the head temp sensor or wiring to the sensor. My opinon only, I think the tune is good since you have the same issue with Midnight and Miller, It's the head temp sensor Can you read the temp off the sensor and see that it is reading correct coolant temps? Not off the gauge but to the DME, these are two separate curcuits. You need zero enrichment when the car is hot...Maybe a pulse you would not be able to see I bet if we put the Inpa or ELM on your car it would read -32 degrees at all times to the DME. My issue when I had hard start issues. Only found by Inpa, ELM would catch this too Perfect start when cold, when hot crank and crank until it cleared the flood then it started...Bad head temp connection...Truth....Ask Barrie John S Last edited by xxxJohnBoyxxx; 04-22-2011 at 12:35 AM. | | | 04-22-2011, 02:36 AM | #25 | Senior Member Join Date: Feb 2009 Location: san jose Posts: 425 | Quote: Originally Posted by xxxJohnBoyxxx That flood issue needs to be tuned out of your tune or you have a bad head temp sensor.
