Ecu Reset -- Final Verdict!

[Danzil]

Yeah i know i know...i've searched and i've read all there is to read.

But theres too much of it and theres really no clear winner.

Still don't know wether to do it or not...?? Help

Thus i was wondering who has actually DONE IT....has it made a DIFFERENCE...and more IMPORTANTLY since some might have done it a while back have there been any negative affects you've noticed since doing it.

Ohh and has there been a universal agreement on whats the most efficient way of doing it? WHAT WORKS BEST.

I just got my straight through exhaust and i've heard its wise to do it after each mod...? What u guys think?

Thanks

well it can't hurt...

not sure if anybody has actually proven any power gains though, as a result of resetting the ecu.

Smoother, get's rid of flat spots SOMETIMES, gets ECU to re-learn after new mods. Won't do any damage.

Disconnect battery, press and hold brake peddal down for 30 seconds.

Dont know whether to do it or not??? WTF

Mate it takes two seconds - does no damage - so whats the issue...

No brainer really

[rev210]

It does take two seconds to do. If your car is not running rough then it won't do anything at all. It does nothing to any of the fuel or ignition maps, possibly helps calibrate closed loop operation but, that doen't affect the power of your car at all.

After evey mod? I didn't bother to do it when I had a gtst. It's not by definition 'wise' becasue it's ignorant of the fact of how the ecu actually does work. Go pick your nose instead, there are more gains to had there for roughly the same time spent.

nice reply rev!

charmer.

the biggest difference it will make is if your car's been pinging.....

the computer will retard to avoid detonation. resetting clears this but if the issue is something more than just a bit of a hot day you will find it pinging and be back to square one in minutes.....

I have a '95 GTS-t and when I changed from a HKS Pod -> K&N Paneil Filter (in the standard airbox) I had rough idling. This was fixed after resetting my ECU.

Same here, ditched the HKS pod and when to stock airbox = dodgy idle.

ECU reset = nice idle

[rev210]

The idle is part of closed loop operation.

As for pinging. If you find your car pinging it will change nothing doing an ecu reset, unless of course the pinging is during very light throttle cruising, because the ecu does not change the ignition map or the fuel map at all. The ecu will still retard the ignition based on the knock sensor feedback exactly the same way regardless.

i like how rev has the knowledge and the balls to say it how it is

good on ya...

like rev said... unless something crazy happened....the computer is just going to retard the timing again....because it is still going to be pinging....

which is what I said.

zanda said it too

[Danzil]

Thanks guys...appreciate the help.

hey, can the battery be disconnected from the front? or must it be the back one?

[MirKz]

u have a battery in the front too ??/

i only have the rear one

[supra]

no i don't have one at the front, but there is a terminal there.... it says +ve and -ve... so I don't know if that is the unit where I can disconnect, but any how, which terminal do we disconnect?

[dan_the_man]

thats for jump starting the car?

[MirKz]

i dont even remember seeing that terminal ahaha

[supra]

thanks, i think so too.
