I did too.Nice write up i read it all,
Should just need to change the Basic and programed numbers. That is what I do with all the conversions I program. The re-encode the whole carTitaniumCranium, I remember you were having an issue where the DME was still looking for the EGS even though the DME software is supposed to be the same for autos and manuals... did you ever figure out what was going on there?
That's what I figured, but at least according to the ETK (bmwfans.info at least, I didn't actually check my local copy), there isn't an auto-specific programmed number for the non-M E46s... Is the ETK mistaken?Should just need to change the Basic and programed numbers. That is what I do with all the conversions I program. The re-encode the whole car
Assuming you're talking about 5MT to a 6MT, the computer doesn't care. The only electronic component in a manual transmission is the reverse switch. To go from a 5-speed to a 6-speed, you'd need a new driveshaft, clutch, and flywheel. You shouldn't have to touch the computer at all.First off, INCREDIBLE WRITE-UP!!!
My question: is it worth it to switch from a 5-spd to a 6-spd? My 5-spd cruises at around 3K RPM, and that's a bit much for me. I remember my Mustangs in college cruised at around 1800 RPM, and that was great. That was also a long time ago, and I would never own another Mustang again.
What type of costs (total) am I looking at for this swap? I just spoke with an independent shop & they said that there might be problem as to the computer not accepting the new 6-spd?
I didn't replace the radiator. It's not necessary but you could if you wanted to. You just remove the auto-trans cooling lines at the radiator, drain, and cap them off. Whatever you do, if you're keeping the auto radiator, don't remove the auto-trans cooler from the radiator or it will spew coolant all over the place (don't bother asking me how I know).I am currently ordering parts to go from auto to 5 speed. I wouldn't think of doing this swap if it wasn't for your great diy along with neil's and ivegotissues. Thank you so much! I have a 02/1999 328i that has a GM auto with reverse fail. I have just one question at this point. This is after reading all three diy several times.
1. I noticed on your diy and neil's you didn't change anything with the radiator like ivegotissues did. Ivegotissues said his would spew coolant if he didn't but you and neil didn't seem to have that problem. If I am correct all you did was remove the two lines from the radiator. Can you clarify this for me please?
Thanks, oh and one last question. If I run into trouble and need a little help during the swap what would be the best way to contact you? Email, PM, or on this thread? Thanks again!
Yikes. . .was hoping for far less costly solution. Crap.Assuming you're talking about 5MT to a 6MT, the computer doesn't care.

True about the engines, but 60 mph @ 3K RPM isn't where I want to be! :thumbdwn:ESS330xi. . .with an engine like the BMW it likes a little more RPM since it is built more for horsepower, so cruising at 60 mph at 3000 RPM is more where it likes to be.
All that aside, swapping to the 6 spd would be nice for gas mileage. If you are cruising at 60 or 70 mph it would be nice to drop it into 6th to save fuel on long trips.
I'm using the auto 330's 3.38 diff. My 60mph cruise rpm's are at about 2300 or so, and about 2700 at 70mph. It's pretty good on gas too. If I'm running at a pretty constant 60-65mph I'm usually getting about 28-29 mpg. As for interior noise levels, I'm running conti dws tires, which are pretty quiet, coupled with 2300 rpm or so the interior is pretty nice on stock sport exhaust. I'm also running a GruppeM intake so that makes that side of the engine a little louder but still quiet enough to be pleasant on long drives.Yikes. . .was hoping for far less costly solution. Crap.

You hit the nail on the head as to gas mileage, but also interior noise levels. It's almost as though the car wants to get shifted into 6th gear, and I'm guessing that's why BMW went to a 6-speed for this car soon after my model year. . .dammit.
