Resetting your ECU with BIG`O

[JasonGilholme]

the same way you did before. Nothing changes.

Its exactly the same as if you get a flat battery. You replace the battery and everything is back to normal.

oh i see, i thought the "back up" fuse is so that if my battery goes dead things will still be remembered, and i thought since resetting means taking that fuse out too, then i thought nothing in relation to the ECU will b remembered unlike the dead battery but yea, im dunno, but now sounds a little more reassuring to do this ECu thing, thanks

[JasonGilholme]

theres no other power supply in your car apart from the battery.

THe backup fuse for the ECU is to prevent any damage to the ecu if an electircal short occurs. It has nothing to do with maintaining power in the event of a flat battery.

hey is it bad to drive a little more 'spirited' after youve done an ecu reset.....my car was driven by a grandma before i picked it up, so im told doing a reset would be useful.....and i want to know if i should drive conservatively after a reset...

don't bother with reset dude.
and have u even bothered to read this thread ? it is quite detailed.

@ Nick_sixx

i find if i reset the ecu i get my fuel efffiency back, but if i flog it after reset, after 2 weeks of flogging it, i need to reset again as fuel effiency drops dramatically.


after reset i use 6.25 - 6.60 Litres per 100km (thats 15-16km per litre)

after flogging it i use 11+ litres per 100km (thats 9 km per litre)




(i base my results on 80% highway driving 20% or less round town as i travel 50km each way 2 and from work inbetween towns - sux working in the country)

Sorry to revive a fairly old thread but relevant to my question,
Flogging = revving it out hard to 6k revs gears 1,2,3?

If so, oops....

Time to reset again???

lol yea floggin = driving the car hard, ie racing.

cant hurt to reset the ecu, u can only end up saving on ur fuel bill ;-)

Yeah I will try it out. I only flogged it for a good 10-15mins or so hopefully I don't have to go resetting it and hopefully driving it easy can fix from now on. (I'm lazy)

its funny that you say to resaet your comp as you make mods, because the computer will re learn the new mixtures and what have you............
well if u was me, u just answered ur own question, it dont matter what mixtures and previouse settings it has, if its a self learning computer, it will eventually re tune itself alone to the new mods..........and then it will also have the base map, which in fact is prob a good thing and wont run like shit on different weathered days, coz by u reseting it with mods and crusing around, it will take all data from that drive, then every time u have different weather or drive it differentl;y, it will be learning again.........so my opinion, no need to reset if its al;ready a self learning ecu........................

So are DC4 ECUs self learning by any chance? I really don't want to be driving around with a terrible fuel economy especially with fuel prices these days...

[IEVAQ8]

i believe so................
