What if I don't want to unplug the battery lead?

it's far easier than shorting out your wiring harness, causing a fire, and watching your pride and joy burn to the ground.

ok maybe i'm exaggerating, but seriously.. taking the battery terminal off is by far the easiest way.

I personally do not feel comfortable wiht the shorting the pin method, because I have not read that in any of my nissan manuals (someone correct me if I'm wrong, because the indexing of the manuals is very bad).

Disconnecting the battery seems to work sometimes if it's disconnected for a long period of time but I hate losing my radio stations.

Nowadays, I just use my laptop to do it. I can reset the ecu and clear the self learn.

correct me if i'm wrong....and i know this is a long standing debate...but resetting the ecu does sweet fuuck all....apart from clearing your error codes.

the ecu learns everytime the car is switch back on. it doesnt have the capacity for long term memory of the parameters you're hoping to 're-learn'.

ive been told this by tuners, and other ppl who have technical knowledge of ecu's. and it makes total sense.

why would the ecu restrict its ability to adapt to new situations, and only work at its best when ppl with 'supposedly' inside information decide to disconnect their battery.

ive tried it, made no difference at all.

It made a difference to my car..

How?

Well it doesnt run as rich anymore..

It doesnt smell as much of exhaust fumes due to the car not running as rich..

The car actually felt a lot better once it was reset..

For me it worked. Gettin more milage.

Remember to dc the alarm.. Otherwise you gonna go deaf like me lol when you dc the battery..

And yup your headunit settings will be reset.

I thought the wires to be shorted were on the ecu, not the fuse box.

Resetting mine didn't do anything either.. Wouldn't the ecu just be set up to react to current environments and not remember the way the weather and your driving has been for the last 6 months.. That seem's the logical way to set it up to me :(

BTW, can I use nissan data scan to reset the ecu?

Reading here: http://202.43.226.57/

Last item on point 4 "clear self learn", that is the one isn't it?

(maybe I'll build one and have more fun with the car :stupid: )

i thought that the ecu would adjust itself to new mods quicker if you clear it, as it would adjust in large increments when first trying to learn, then smaller and smaller as it gets closer to optimum. when you change something tho, it has to use these tiny increments to get to the new optimum running...

so reset it and it starts off big again

thats my lil story :(

I don't know about data scan. Its not my favourite consult software. My software can result the ecu itself as well as the self learn.

What are you using dude? At the moment I'm using ECU Talk, but I'm interested in whatever does the best job.

      Out here E90s are the cheapest way into a sporty-ish car because everyone knows just how expensive the repairs can get. 8-10k USD for an automatic 335i.

      Noted. Have noticed BMW are more 'high maintenance' for sure. They've attracted my attention as I think the used car prices seem reasonable vs other options, and the extra quality overall vs a commodore / camry / corolla or similar of the same vintage is appealing, especially the interior, and they are more on the sporty side whereas the others mentioned can be more cruising or economical A-to-B only.

      Haha yeah I know, this is SAU after all, why are we talking about BMW's of all things!? I hear you on the 'don't have to worry about it' side of things. Having been fortunate enough to be have been able to buy a brand new motorbike or two...never really enjoyed them as much as I'd have liked as you worry so much about where you park it, will it get scratched, stolen, attempted theft, knocked over, etc...and yes dirty. Older less valuable bikes you can just go where you want and park it wherever and not really worry that much in comparison. And who cares if it gets dirty! Never owned a V8, and have had my eyes on VE / VF commodores for years but with their prices climbing so high, the M3 has come into focus more as prices are much closer than I've ever seen...is it a potential contender now?...of course need to factor in the S65 'maintenance' especially and like you said general M car 'tax'. One can dream anyway. But more on the reality front - did read the whole 330i thread as well and was a great read too, both threads enlightening as I've never even driven one of these cars! I do recall 330i didn't seem to have the same amount of issues for almost the same car (turbos and related differences notwithstanding)...perhaps down to getting it earlier in it's life so looked after better than the 335i? Perhaps so as your 130i has been good and quite similar, so finding a car that's been looked after well is the especially-crucial-BMW-first-step.

      Nice. Dont worry about the time of not running. My current skyline hasn't run since I bought it. About 8 years ago.

      It's also worth noting that I am heavily and unconditionally biased. I've had a lot of cars including some GTRs a fair while ago. I love my BMW's now a lot. They make no sense a lot of the time and the guys on here remind me regularly that I could get something else that does what I want better and cheaper. If you're going to take on an older BMW it's definitely a commitment. If you bail on it early you'll lose money and also the ability for it to put a smile on your face. Stick with it and it just gets better.  f**k I should get into advertising.
