Stagea Remap Ecu

[Tangles]

OK

Letting the cat out of the bag

Im currently dealing with SAU member Toshi from NSW for a full ecu remap to my stagea ecu

I contacted Toshi, gave him all part numbers of my Stagea series 1 auto awd ecu, along with a photo of the internals of my ecu.

Toshi confirmed that he could do a remap, but my ecu would need an adapter plate from Japan.

He also got details of the ecu from japan, and is currently writing a chip now.

Total cost for me is $650, including adapter.

Pretty much once the ecu is written, and I get it with the adapter, I go to a electronic repairer and get the current ecu chip cut out (must keep), the adapter chip installed, then the new re-written chip installed into the adapter.

My ecu is a 0V300, unfortunately Toshi can only get data from japan for the 0V301. Im positive there wont be a difference.

With this re-written ecu chip, Ive given toshi all my mods, asked for a 1bar tune for a highflow turbo similar to a hks2535, etc etc. speed limiter removed, rpm limit of 7000, etc.

Only thing is, being interstate and a "guesstimate" tune, I will be keeping my safc/sitc piggybacks, set them to zero, install the remapped ecu chip, and then get a good dyno tune done locally.

Just letting people know. It isnt done yet, but it well under way. Dont go rushing out, as it may not work, but will update you in a months time with the end result.

[Tangles]

so what you need to do if you do the same path:

Give Toshi details of all mods

Give Toshi photo of internals of ecu

Give Toshi details of all numbers on ecu

work out a deal, and hope for the best

[jippa]

so what price guestimate u looking at after installed and tuned

[Tangles]

$650 for the chip and adapter

$100 for the electronics bloke to solder in

$350 to service the engine and dynotune the safc/sitc

guesstimates only

[yokotas13]

luckily

i jsut did my tune

800.00

take my ECU

install daughterboard with tune loaded in

call it a day after they tuned it

[Tangles]

yeah, Toshi looked into the daughterboard but with my ecu it couldnt be sourced (easily)

I'll be happy once its done, if it works.

Will let you all know in good time

(last modification for my stagea)

[yokotas13]

i MIGHT be able to buy the daughter board from the shop that did mine.

if you actualy end up needing ont

[Tangles]

Thanks for the offer mate

Toshi has already sent my money for the adapter and received it with the ecu data he needed

so, it should be all good considering the tune can be "fine tuned" on the dyno with the safc/sitc.

cheers again

I've also been speaking with Toshi, very helpful guy. I'm doing a shite load of work on the Stagea atm though and unfortunatley this just ran a little over budget for me right now but was definatley going to do it in a couple of months once the wallet has recovered. Please let us know how you go as this is something I definalely want to do. I've also got the SAFC and SITC combo so if it needs fine tuning I'm already set. Will be watching this thread for sure

If you do a search for him on this SAU you'll find there are already quite a few happy customers that have had his real time tune, I was going to drive interstate and do it that way (still cheaper than a PFC and dyno time) but like Tangles said he can't source a daughter board to do this but was still quite confident that he could write a chip for me. Factory ROM tuning was and probably still is quite popular in Japan.

Why dont people just use the Emanage ultimate. For around $1k installed it is a lot cheaper than this (combined with the price of the SAFC and SITC) and it is a factory unit that can be tuned by a number of different workshops. Just a thought

[Tangles]

because when lads like myself grabbed the safc/sitc combo, emanage was over a grand and no-one really knew how to tune them (in adelaide at least, can pass a few stories to you about blown engines and electronics, etc). so, 30months back, it wasnt a viable option.

personally, from all research, the re-written ecu chip is as good a "mod" as a tuned Power-fc. just that it cant be retuned on the run as per the P-fc. no point in ripping out the safc/sitc combo, and installing emanage as it isnt cost effective, frankly.

safc $350 new, sitc $250 new, chip $750 installed, tuning. same price as power-fc at the end of the day, with similar results (albeit stock injectors.....). even if you do the emanage, the re-written chip would still be of good benefit to do.

chip / adapter has been posted, so will get it fitted in the next 2 weeks, and tuned on 19th June. results will be shared.

[Mr_RS4]

Considering the amount of talk in various threads that was going on here 12 to 24 months about the emanage unit most of us have done the home work in fitting one to a stagea and some had even tried it. But people were having a lot of issues with blowing coil packs or worse and finding installers and or tuners was not easy. The safc and sitc were easy to install and tune items that were worth a lot less at the time like what was mentioned above.

At least with the chip your not relying on voltage benders to tune the car you retain all your stock ecu functions and you can actually change the closed loop maps which is something even the safc has no control over, which is something that does bother me a little because like Tangles said about using the safc and sitc to tune the car if there were any problems with the chip if the map problem is when the ecu is running in closed loop then the safc isn't going to make much difference. But I believe toshi will re write the chip if there are any problems.

I'm still looking to this as my personal best option to tune the Stagea. Even if it were manual I'd still look at this option as I don't plan continuing upgrades that are going to require a new chip to be written each time. I will do what I want to the car and then do this and that will be it.

[Tangles]

yep, last mod for me.

even if the turbo blows in the future, will stick to a hks-2530 or hks-2535 and this chip will suit.

and as you say, any issues and Toshi will re-write the chip.

[Duncan]

I wouldn't worry about the remapping. once the eprom chip is in there are a few workshops that can remap them for you

[Mr_RS4]

If your talking about real time mapping I thought a seperate daughter board was needed. But I have no idea. Factory remapping is new to me.

[Tangles]

Hopefully get my ECU back by wednesday, tune booked for thursday

excited, hope it works !!

[bbenny]

Cant wait to hear how it goes!

I had Toshi do a ship for my R32 a few years ago as a "guestimate" tune and i can honestly say that it was the best bang for buck mod I did on my car!

Good luck!

Ben.

[Tangles]

Bloody-well works !!!!

Getting dyno tuned tomorrow (19/6), safc/sitc reset to zero

road tested, all gears as per before, shifted well. snow mode works, 50/50 transfer button works

overdrive button works, as do lights, wipers, radio etc etc. all functions.

didnt test it hard, but booted to 5500rpm, no knock that I could hear

fuel pump sounds slightly different in a way (?),

1st gear has a hesitation at 10psi, second boots to 13psi, slight hes, then boots to 16psi (backing off)

safc/sitc tune tomorrow will help immensly, iron the little areas out on the dyno

pretty sure you can pull the brown fuse in front of the battery to lock it in 3rd gear, so can possibly get a good 2nd gear then 3rd gear run.

we'll see

report tomorrow/friday latest with end results and thoughts

[ssshonky]

gets popcorn and waits overnight for the results!

[Tangles]

This mod is Definately a goer

has got my full support, thumbs up, seal of approval, and all that mumbo

BUT in my recommendation, only in conjunction with a SAFC, some sort of way to adjust the air fuel on dyno

definately 200kw available, but for me, alas, still pressure drop.....drops from 1 bar down to 12psi

need better freeflowing cat converter, instead of the one I have (ebay, lol) which is obviously too restrictive

put on dyno made 82kw down from 180kw

backed fuel pressure right off made 130kw

adjusted fuel ratio right off (ie backed out a lot of fuel) and made 186kw after finetuning

timing was essentially spot on, just a touch here and there

taken a fair bit out with the Safc, dyno'er reckons 200kw is easyas with a good freeflowing exhaust

dump pipe is fine, muffler is fine, so must be the cat. did the Rev210 intake mod, so everything is done, just got to get a good cat and

fine tune on the dyno again - get that pressure drop to neglible and see the result
