Resetting ECU - a how to?

I've noticed a lot of posts stating that to fix certain problems then it may be necessary to reset the ECU. As far as I am aware, the steps to do this are:

1. Disconnect the battery terminals

2. Press the brakes a few times

From a standard ECU point of view, this resets the works and requires the ECU to relearn timings etc..

How does this work with a non-standard ECU that has been tuned? In terms of resetting the CPU, does it also wipe all of the mappings performed by the previous tuner?

I would hate to reset my CPU to find out that it gets me back to the stage of it relearning itself and thus requiring to be tuned once more.

I know this may seem like a fairly obvious question to some, but I am quite interested in the answer none-the-less.

Cheers!

Giles

If u r talking about the power FC then no it will not reset by disconnecting the battery. It has its own backup battery.

What makes u say the ECU is giving u problems?

If u had a few problems due to the ECU then I would imagine u would have to have it tuned on a dyno again.

Nothing specific to any problems I'm having. I've been reading the forums and notice reccommendations to reset the ECU to fix problems with things such as fuel consumption problems or other various issues.

I was more wondering if this is isolated to just standard ECU's, or if it is something that should be done all all ECU's if required.

My fuel consumtion has improved since resetting the computer. 180 out of half tank, I'm headed for 300 plus, improvement on before 260 (full tank). But I have been driving like a stiff.

What I noticed when I reset it was I went for a drive imediately and my steering was wierd, I had to do a half left turn to keep the car straight. This was I guess the computer resetting it's self.

      DeAgostini 1/8 scale BNR32 Nissan Skyline GT-R Nismo

      By Rezz · Posted

      Starting with issues 1 - 5, we have already run into a problem...!  Issue #4 contained 2x front brake calipers, instead of 1 caliper and 1x steering knuckle. Will have to call DeAgostini on Monday to sort it out. Anyway here's some photos.  Issue #1 is the front bumper, headlights and number plate. Issue #2 is the front wheel (with "We produced with spartan air." text on the centre cap!) and tyre, the front lip spoiler and cylinder head cover with ignition coils under the centre cover... which will never be seen again. Issue #3 is the bonnet and cylinder head. Issue #4 is the front strut, brake disc (with laser etched metal discs) and brake caliper. I stopped here because of the issue with the missing steering knuckle.  Next update will be #5 - #10 in a few weeks.

      DeAgostini 1/8 scale BNR32 Nissan Skyline GT-R Nismo

      DeAgostini is one of a few companies that release quite large (the largest commonly available size actually) 1/8 scale models in a series of weekly issues over 100 - 110 instalments.  They release different models for different markets and DeAgostini Japan have release the BNR32 Skyline GT-R Nismo last month. I've made two of these 1/8 scale sized cars (one an R35 GT-R from 2012 - 2014, the other I'm just about halfway through, a BNR34 Skyline GT-R from the 2Fast 2Furious movie) so when this R32 was announced there was no way I could ignore it as it's my favourite out of all Nissans.  Each issue costs around $20 so it costs about $2.2K when completed. I suppose it is very expensive for what it is, but the quality and details are really very good, and there are many "gimmicks" like fully functioning exterior and interior lights operated with a remote control, working steering, all doors/bonnet/boot/fuel lid open and close, the side mirrors fold in and it even has a speaker for the engine revving sounds when you turn the lights on.  Each issue comes with a magazine that tells the story of the BNR32 Skyline GT-R Nismo from the first design stages of the BNR32 to Group A homologation and the various racing version that were run in the Japanese Group A and JGTC, and Australian Group A.  So I plan to update the build in this thread 5 issues at a time.  https://deagostini.jp/r32/?srsltid=AfmBOooKjxDc4EUK2rmXqMBPgyHfFJ24s4oEPJBNpnF-lFlsRoW0PE6P

      This would be a new pump with new gears. I'm just unclear on whether it's a good idea to run more oil pump flow if you don't actually need said flow. Oil level is set a minute or so after shutting off a warm engine so wouldn't the high RPM oil level in the sump end up lower all things equal? Plan is OEM clearances, main concern in my mind is whether the OEM pump can keep up with the flow requirements of any additional oil coolers.
