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

-Dan

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 :D

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.

      Skyline v36 350GT sedan hunting on idle

      By Robot · Posted

      Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.

      Jacks that fit under GTR lips that can reach the subframe?

      By MBS206 · Posted

      For race cars, this is one part where I find having the roll cage bar having gone through a hole in the floor better than the build it up on a ledge inside... The Merc I help on, the main hoop ends are marked on the car, and the jack is marked... Jack goes under a few inches and lifts one whole side of the car up... Removes that fight for long slim jacks for race car duties!   My biggest issue for the daily drivers I work on, is my jacks don't go high enough. The jacks start out on a few blocks, jack it up, then start a second jack under it on more blocks, and then I can get an axle stand under it. My axle stands are presently in use, and are nearly fully extended. The car is sitting with barely more than a cm of clearance to get the wheel off the studs! Sarah's Kluger is the same, as it has an ungodly amount of droop available in the suspension and a distinct lack of good jacking points!

      Happy? Yep, my to do list is getting shorter and shorter. Either this light approaching is the end of the tunnel, or I'm about to be hit by a train... Ha ha ha   Also, Duncan isn't that far out of town that you need to make a multi day drive out of it. 😛
