    To get rid of the CEL use inpa to clear the engine codes. Then use it to clear the adaptations. Turn the key off and remove the chip from the tranny computer. Now start the car and the CEL should be gone. If not then try again.

    To remove the auto tranny warning light you either get a 5 speed dme and alugn the EWS or you'll have to find a tutorial on how to recode the current dme to a 5 speed dme. I've been successful recoding but I use DIS. You probably don't have that installed.

    That's what I did. That's what just about everyone has done. Try swapping the procedure around. Try clearing adaptations then codes then the chip.

    Damnit I'm sorry I pmed you. Didnt think youd respond to the thread so quickly. But okay I guess I will put the ECU ordering on hold for now. I will give it another go with your instructions tomorrow. thanks because I am going to manual swap my M3 next so this is a learning process that will make mine go smoothly :P

    Well i have tried that procedure about 15 times now with no luck. Replacing the ECU with the manual one will also take care of that CEL, correct?

    Yes, that is the main purpose. It will also take care of the rev hang, and other little things. But not of any other modules' settings, like ABS etc.

    Looks like that is the way I will go. The abs isn't really functional in this car as is. And I have deleted the Traction control prior to the swap. Also the part number you posted is specific to manual DME's correct? I found them as cheap as 30 dollars shipped..is this maybe because no one wants 318 stuff?! I have to make sure the software is ms5.2 correct? sorry for all the questions..

    Yes, but crosscheck the last seven of the VIN on realoem.com to make sure it is from a manual 318.

    If you can't get your laptop to have wireless working, I can guide you over the phone how to code the car to manual, much simpler and faster than me putting up extremely detailed step by step directions.

    Damnit Well I had her order an ecu already. I didn't see this post until now. >_<. I will try installing the new DME and align the EWS and report back.

    Guys I would like to thank you..everything is great now. $70 for a new DME. Aligned the EWS in seconds, started right up..had some weird code...disconnected trans computer no more code or lights!

    Now to figure out this damn vibrating roughish idle, And yes almost everything rubber has been replaced..lol

    That's great news. Glad it worked out.

    Yes i really appreciate you offering the help too! I am glad we went this route because it seems the car does not have the rev hang like it had before and my girlfriend said it drives much better. Not sure if its just because we know that it has a manual computer now and its her mind or it actually does drive better! lol

    Quick INPA question..Cylinder Smoothness... front two cylinders are matching numbers almost around 150 160 and rear is alot lower but matching

    Cylinder smoothness is calculated from crank velocity at moment of ignition, using the crankshaft position sensor. If the values are drastically off, I would look at fuel injector, spark plug, and ignition coil condition. Maybe even move coils and injectors around. Also, make sure you don't have a vacuum leak somewhere. I know you said you changed all the rubber, but look at things that can have cracks... or o-rings at fuel injectors/pintle caps, etc. A smoke machine can identify all leaks.

    In the past, my 328 had 1 major leak, and as I repaired that, other minor leaks started showing when smoked... until the very last ones, at the fuel injectors' o-rings. It ran massively better after some 8 minor leaks were repaired.

    And yes, the rev hang is part of the automatic software, to help the automatic transmission shift properly. It is not in her mind for sure.
    The manual software is different, there are different part numbers for manual and automatic software. These ecus usually have both auto and manual maps programmed in them, but they have to be activated.
    However, there are subtle differences between auto and manual flashes, even though they contain data for both.

    all 4 injectors were just replaced, remaned BOSCH units. Had a horrible misfire under load. and one injector was bad, so i said we are doing all four..at 80 bucks you can't refuse that..Plugs were done last year. Wondering if its wires or the coil. We have replaced all rubber under and around the intake manifold with oem bmw parts, so I know thats all good(precautionary) when the engine was out for the manual swap, kinda just freshened everything up.
    DO you know what the values should be? I read they should all be within the same number as eachother.

    Whenever you can, take a screenshot. Each ecu has its own values, so that 150 doesn't mean too much.

    Will do, What do you want a screen shot of? The smoothness at idle? Any other things?

    Yes, smoothness at hot idle, fuel trims (adaptation multiplicative, additive), and any remaining error codes (including shadow codes).

    I made a few changes to the fuel mappings and I like the differences however right after I start the car (maybe 10-15seconds afterwards) when the idle settles in and comes down off high-idle, the motor is stumbling and stalling. When I revert back to the old flash (modified/not stock) problem goes away. I'm still new to all of the exact fuel mappings and DME settings and when I compare old vs. new there are a bunch of changes --can someone point me in the right direction please? Simply looking to have the idle not drop down so quickly. Idle speed is OK once warmed up, just either drops down to low too quickly or as it drops its cutting too much fuel during the drop.
    Thanks.

    email me. Not sure which file is causing the issues, your modified one, or the one from me?

    Hi!

    How about old 1993 E36 (325i cabriolet), where is only 20 pin connector under the hood and where is pin 15 (RxD) and pin 20 (TxD) connected, but pin 17 (TxD 2) not occupied. Does this KKL cable in this old BMW model or do I have to get real ADS cable / interface or what?

    I have not yet found a clear answer to this question, or then I just do not understand read about in.


    Thank you!

    The KKL cable will not work well. ADS is needed with a true serial cable on the computer for your car. I have heard of ICOM with adapter C working as well with L line and K line. It connects to computer using ethernet.
    Unfortunately, INPA does not work well with <1996, you will need to use DIS software.

    OK, thanks.

    Do you have any idea, where can I get this DIS software? And what you think about Carsoft 6.5 or later?

    What is going on with it?

    Try the method at the bottom of post 1.

    Usually torrents.
    I have a Carsoft 6.5 (collecting dust). It's quite weak, but will be good to read and clear a code.

    I can't seem to select XP SP 3 compatibility. Everything unpacked fine. I did modify the Temp path. When I run the first exe (BMW tools) I get pretty far along (e.g. Set the language to English) and then it stalls and I get the message Only NT 4.0 and XP Professional are supported.
