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.

      RB26DETT Sketchy boost mod?

      By ARB26 · Posted

      So could it be assumed it has been installed intentionally with potentially a power FC boost controller kit?

      What should I do next to hold the head on

      By Gareth87 · Posted

      Had my rig on Matt's dyno at PITS the other day. After a few years between tunes I added a few sensors and swapped intercoolers. Result. 553hp at 26psi. Not bad for an FJ20 that was built in 2007. The problem.. It filled the overflow bottle on hard runs which leads me to believe the head gasket isn't sealing. I have a coolant pressure sensor which was reading cap pressure at 22psi and occasionally overrunning to 23/24 psi on deceleration after a pull. It was not spiking. It has arp2000 head studs and a cometic gasket. As its been 18 years in service, I pulled the engine out and head off. Everything looks good but we obviously have an issue. Where I'm at.. Years ago I had the same issue, I checked the stud tension and they were all over the place. Some at 60 to 70 and some up near 90. I nipped them all to 100ft lbs and this stopped the water push until now. I believe this compromised the gasket back then. What do I do? 2 options are..  1) I bought arp 625+s, which I could put in with a new gasket. Thinking Kameari this time, reassemble and try again. 2) strip the block, get fire rings machined in with copper gasket and try that. I do not want to push it more than 28 to 30psi. I think the turbo will be out by then anyway. (G30-770). My other concern is the long term ability of a copper head gasket. Are they streetable for years? I feel like a new gasket with the new studs will probably suffice, but I don't know. Any thoughts welcome and advice on copper gaskets and fire rings. Thanks!

      I'm a fan of the JZX110, and the Aristo. Big cruiser cars, and with the factory cars, super comfortable and feel like you're driving an armchair! And the JZ motors are a pretty nice engine too, especially with some basic mods.   The import process, and the need to be able to trust people, and the fact there's so many scammers around is what ever puts me off wanting to go through that ordeal!

      I don't care for these at all, but at least the underside looks straight and not rusty. A good basis for a long life. Many cars from Japan have been lifted with forklifts and f**ked almost irrepairably.

      RB26DETT Sketchy boost mod?

      By GTSBoy · Posted

      Yes, but it's not dumb or dodgy. You can build a perfectly good boost controller from a pressure reg, a relief valve (looks same same as a reg if all from Norgren or SMC, for example) and a check valve. I ran one for years. Only superceded with  EBC because I could get one for cheaps and wanted finer control.   THis mod is certainly not a sketchy boost mod, provided the boost is kept below the "spin to death" threshold of the turbos.
