Engine ECU - Reprogram Auto -> Manual

Recommended Posts

Having made the change, am looking to get the engine ECU reprogrammed to the specs of a manual. This needs to be the whole ECU - including the engine data Eprom. Does anyone know who can do this in Christchurch? I have got in touch with the local dealer (Jeff Gray BMW) but haven't heard back. Is there any BMW specialist workshop, or perhaps any one else, around that will do this type of work?

Thanks. :mellow:

Another option is to get a second hand DME from a manual and realign with EWS if it has EWS. If no EWS it's all straight forward

I didn't think it was necessary to do this on the e36

can't say I've noticed any issues leaving mine with the original programming (almost 18 months now since conversion)

Might be cheaper to get a manual ecu?

It's not necessary, but there are some quirks if you don't.

Higher idle.

Revs sometimes shoot up a lil bit when changing gear.

Mine has been recoded. The idle is fine, but a tad slow at times coming back to idle. It maybe the light flywheel. I'm still trying to get my hands on a Siemens DME for a manual 328i to try, but it's not that much of a concern to really worry about.

I'm not sure if mine has been reflashed? (I think it has), but i sometimes get a little bit of revs hanging in between gears - only on partial throtle. Taking your foot off slightly earlier when changing gears is a 'fix'

Your DME still thinks its auto.

There are two things here.

Coding the DME to tell it to ignore automatic gearbox states

Flashing the DME to be a manual DME (includes automatic gearbox idle/load adjustment removal)

The light flywheel will slow down much quicker than a heavy one when going off throttle. A lightened flywheel has much less rotating mass and inertia to resist the decelerating effect of closing the throttle. It is this reason that an engine with a lightened flywheel does not "hang on" as well, say, when chugging up a hill. Heavy flywheels with a high rotating mass take a long time to speed up - and also slow down.

^^^ My theory as well..however some people in the "know" say it's possibly the flywheel. Thats why I want to try a Manual 328i Siemens DME for a M52B28 if anyone has got one

As far as I know, Sam never resolved the problem and has since sold the car

Can't say I have ever noticed it but I'm definitely going to be keeping an eye out for it now.

Well, time to report on the latest. Took the car into Jeff Gray BMW today. Had rung them about 10 days ago and after a day or two to think about it they got in touch to say "Yes, we can do it, bring it in."

Long story short, No they could not. For those who thought this will cost an arm and a leg, the bill for their time was less than $70. Probably 30 minutes, charged 6 time units.......... Not a hell of a long time trying everything, I would have thought, but then again I wasn't there.

They told me they tried everything they knew, even got in touch with Auckland; but nothing worked. Some story about my particular car and the time of manufacture etc etc - but at the end of the day, they did nothing.

Where to now? How did you get on, Glenn, with your experiment?

Who recoded yours, Glenn?

I've got a manual, non asc and non traction control ecu from an m52b28. I've no longer got any use for it
