Failed Smog/Emissions I failed emissions today I failed on 2 areas. Low speed Hydrocarbons too high, easy one to fix. Run the test in 1st gear and get the revs up, hotter exhaust gas will help to burn off the excess carbons and the RRFPR dumps fuel in on the low end, higher revs would help with this. The second area is the real shocker. I failed because the CEL is on with 7 codes. CEL bulb was removed because it sucks, my guy looked the other way on that and a few other aspects of the visual test. Here are the codes. P0743 TCC circuit electrical failure P1761 Shift Solenoid Malfunction P0753 Shift Sol A electrical P0758 Shift Sol B electrical P1423 Secondary Air Injection failure P0443 Evap Purge Valve Open or Short Circuit Fault P1174 Fuel Trim Adaptation Additive Bank 1 Malfunction Most of the codes cleared when hooked up to a scanner. The transmissions codes could be fixed if I swap my ECU with one from a stock 5-speed. Unless the VIN is programmed into the ECU? Are they? The one I don't know how to fix is the P1174 Fuel Trim Adaptation Additive Bank 1 Malfunction. Any ideas? Will swapping the ECU work? Or should I get NickG stage 2 software to adjust fuel delivery on the low end and have it written for a manual if possible.:biggrin: (this is a nice thought but not visible at the moment) |
Are there any shops in the LA area that can reprogram the M44 ECU? |
pm hugo hes done all sorts of stuff to his ECU if anyone will know its hugo :) |
Did you take it to a "Test Only" station? |
Yeah the station was a Test Only. |

Lazoh thanks for the offer. I may have found a shop that can re-code the DME. But first I want to ask. Has anyone had work done by the M shop in Eagle Rock? http://www.themshop.com/index.php |
The M Shop is usually booked all the time. Last time i was there, a guy named joe (owner and bmw master tech) was on the phone with a customer "i have something until 2 weeks." I laughed. Joe has a 332ti with the stage 2 AA supercharger kit pushing over 400hp on his ti :smile: The guys there are kool. Note: i have never done any work there. I used to stop by and say whats up. |

for the 2 below, you may wanna check the secondary air pump (make sure all rivets are in place - mine were busted & the air was coming out though the seems of the pump) and the shut off valve (take the thin rubber hose of & make sure the nosle isn't cloged - mine was).. good luck. P1423 Secondary Air Injection failure P0443 Evap Purge Valve Open or Short Circuit Fault |
I stopped by The M Shop today to say whats up. As of today, i heard him say to his customer he has something open until march 19th. LoL, damn this guy is getting business. Man, now they have two Ti's with s52! Last time i was there, he had the s52 with AA supercharger in his ti (the pic i posted). I stopped by today, and now he put a 6spd tranny on that same ti now. Along with the supercharger and s52 doing 400+, i forgot to mention he has a 3.73LSD on. That sh!t must be facking fast! |
i could only imagine...... im drolling a little... damnit |

I talked to Joe at the M shop, really nice guy. he told me what I need to do and he is going to help me out. I need the 7 digit part number and vin from a manual '97 ti active package and he will re-flash the DME with the program from the manual on my DME. Does anyone have a '97 active 5 speed that would help me out? |
Does anyone know the 7 digit part number for a '97 manual DME? Or know where I could find that info? |
http://www.realoem.com/bmw/partgrp.d...3&mospid=47506 just make sure you select info for a 97ti.. Quote:
