I've seen the instructions somewhere, may have been on Skylines Australia or possibly even here. For the amount of effort required it's almost just as convenient to just install and wire up an aftermarket ECU.

Although, I've seen videos of a FJ running on the SR management, and by god does it sound crisp. Search for "1511zeki" on youtube :D

Mine seems to be using a jumper harness.

I need engine management.

If you want to sell the SR setup then...

I will probably be keeping it and flashing the stock ECU some how. If not, then PowerFC or AEM.

This is what you want then

http://www.nistune.com/equipment-products-type3.php

It was developed by a guy in the R31 club, I was out at his house one day picking up some extractors I'd bought from him and he showed me a little test rig he'd put together in his shed using bits of an RB30E, I thought it was just some weird little project... He's now gone from that original setup for the RB30E to having boards that work with pretty much every performance Nissan engine (except the FJ20 :() including the GTiR SR20.

This is why I'm kind of interested in doing the SR ecu conversion on my DR30

Here is a few more pics of the DR30, It's going to get its summer wash, wax and polish very soon. The paint is getting pretty swirly. Also had the new muffler and tip welded up and installed to replace the rather low flowing Fujitsubo muffler

I recently scored a deal on some new tires 225-50-16 Yokohama Advan Ao48 for $74 each, so currently those are installed on the rear as they would be too large on the front. Also installed some larger spacers to make the wheels fit proper.


PS: Is there a reason why my pictures are not posted properly?

Rather than using stock Nissan computers, why not just put it on megasquirt? Infinitely tuneable (and easy) and much easier to wire in than another stock computer out of another car. And you can ditch the MAF and run speed density with the MAP sensor, a much better option in my opinion.

I agree with the idea of going MS, just depends on cost and time. Calibrating sensors, routing the wideband and then learning the software. It takes sometime. Only reason I did it is I took the car out of commission to do everything.

Because they don't need infinite tuneability, and theres lots of functions you probably could emulate with a megasquirt, but are a lot easier to just use the workmanship and time of Nissan's engineers. Plus theres something to be said for using OEM components.

Do that and THEN add a Nistune chip and you have a fully tuneable ECU which can still operate in an OEM fashion.

I got a mines for mine and I tend to agree that a full after market jobie would be better for the effort ? More tuneability and there is nothing particuly oe about a chipped tunned ecu anyway is there? but Fair enough...

Sorry for the tread jack!

That's a great car bud keep it looking sharp!

What, like maintaining factory default tune as a base, cold start, closed loop, acc compensation, self learning and a bunch of other stuff? If you ignore fixed maps most factory ECUs have functionality its difficult to emulate with a standalone.

My ECU is mated with a jumper harness, so I could plug in a factory ECU if necessary. Ive looked into a couple different tuning softwares, mainly Nistune. Right now I will just keep the SAFC Neo that I am using, since I have safety and emissions here every year its easy for me to tune it to pass and then tune it back for a bit more fun.

Thanks for the compliments guys, a friend of mine is doing a photo shoot of my car sometime next week, so i should have some more pictures up by the weekend. Thats if I can figure out how to make the pictures work, if anybody could help me with that it would be appreciated.

Board Preference>Edit Posting Defaults under user control panel. Not sure why it would have changed though.

Does anybody ever completely remove the IACV and bump up the idle using the throttle screw?

if you're referring to the AAC valve, I've seen it done in Japan on the odd occasion.

I considered it when replacing a heap of things on my coupe the other week but decided against it mainly because it means you no longer have any form of cold start control.

you could block off the signal line to the AAC valve and that does pretty much the same thing as removing it.

It's been a while since i've posted. I got the AAC and IACV valve removed, car idles nicely at 1000rpm now. I also decided to pick up a nice large rock on the freeway shattering my front window.

After a few months I finally sourced 2 windows (an extra one just in case) out of Japan from Ewan at Hayatonka, everything went great and got them to me in less than a week after they were shipped. I will definitely be limiting my freeway driving as I would rather not have to spend $1600 on windows again :)

Here is a couple shots of me having some fun during a play day at the local race track paddock area. It is very rare that I do something like this, but it was fun. The car is running better than ever!
