Piggy Back And Ecu Tuning Discussion

[DaveB]

so it sounded good did it? bugga, so needing to hear it / see it / drive it after 3 weeks of anxiety, lol

yeah white series 1, the 2x oil restrictors up in the head was loading up the bottom end pressure and leaking out through the turbo oil seals

hope they arnt rooted, spent this weekend worrying looking at 2nd hand hks turbos.... hehehe, no cash tho.

they are making up an oil restrictor for the turbo line, just needs to be balanced well to not let thru too much but yet enough for the journal bearings

no, boostwerks arnt usually open on weekends but coming up the xmas they are flat chat

glad to hear they looked after you and got stuff done. best to always let shaun know what you want done with a list of work, set a date and let them do their thing.

hopefully can report on the safc + sitc + fpr + Toshi remap + poncams / highflow / headflow work...... soon .....

lol damn... yeah I'd be hanging out to see my stagea on the road again after so long... I had mine off the road for a few weeks recently and it really sucks (save lots of money in fuel though )

Did you end up getting her back for Christmas?? Hope you did. Have a good one all (11:59, 24/12 )

Hi guys ive posted in here a while back saying i was needing a piggyback ecu, now the guys fitting it have tried a unichip and vipec with no joy has anyone any ideas on what to try next??

cars stats are auto 97 rs4

Shift kit

hks exhaust incl downpipe, de cat

hks intercooler

Hks gtrs turbo

Hks boost controller

uprated fuel pump

Adj fuel reg

z32 airflow meter

Seroiusly, convert to a manual gearbox with those mods. Then can run any computer option.

I would have thought an E-manage Ultimate would be the best option for you. That hooks into the original computer, I run one and its great in my car. Only problem with them is finding someone who is experienced enough with it to tune it properly.

[wolverine]

what was the issue with the ViPec and Unichip?

if they couldn't get these working then there is little chance they will get anything else working unless you can give more information on why they couldn't get them to work.

Try someone else. I don't know about the uni-chip but the Vipec is the same as the Link and the latest version of that can allegedly handle the automatic box. When you say "no Joy"what do you mean? They don't know how to fit it? Can't get it to work at all or properly? In your case the Vipec should be the best bet. Here in Auckland NZ (and there are a couple of others in Australia) there is a guy who installs a daughterboard in the stock ecu and then a tunable chip. I don't know if any of these guys are prepared to share their software at this point so probably not much good to you. The Vipec/Link should be able to do what you want with more grunt than a Power FC and the added functions such as being able to retard timing etc during gear changes. But you probably need the top of the line model not the basic one.

Haltech Platinum Interceptor.... 750 bucks.. has anyone run them?

I hear GTAuto is going to try a Haltech Platinum2000 in a piggyback mode on a stag this week.. I'll let you know what I hear...

Yes, but it the results are on a mildly modified M35. (turbo & turbo back exhaust)

update:

AEM FIC/8 piggyback controller is being wired in soon, to replace the safc & sitc.

the F/IC8 runs 3lots of 21x17 maps, for air:fuel ratio, injector duty latencies, & ignition timing

all up thats 1071 potential tuning map points, compared to the basic safc/sitc combo

also have now a $100 Dell latitude 640 laptop to run Nissan Consult full version & the AEM F/IC-8 program

so it reads from the consult cable and tunes via usb for the AEM piggyback computer

Will be dropping in 6x S15 injectors (have 2 for sale), adjusting the duty cycle, air:fuel and ignition timing, and hitting over 250rwkw

not bad for a $450 piggyback ecu and a $100 laptop

Can anyone confirm if a 25t RS FOUR V AT 99 model Stag computer work in a RS FOUR 4WD AT 98 model Stag?

Was thinking of getting one to have it chipped and keep my original for backup.

[KiwiRS4T]

Are both cars S2? Have a look at the ecu number...I would think they would need to be the same to be sure.

[Stagea_Neo]

mines a 98 s2, being it's out of a 99 rs four v, i could only assume it's also a s2.

gonna pull of the kick panel shortly, have a look see if anything matches.

i know mine is a jecs but that's all i remember.

[Stagea_Neo]

here's a pic of the cpu stickers.

mines on the right.

the rs4v is a 2wd right?

im still only assuming the rs four v is a series 2, it's out of a 99,so pretty sure.

the numbers aren't exactly the same, so not sure if it would work or not.

[KiwiRS4T]

As they're not the same frankly I don't know. Have you bought the second one? If it is not too expensive you could buy it any way and bung it in for a trial. If it doesn't work it shouldn't be too hard to sell as they seem to be in short supply. But you are not really in need of a backup - I have not seen any report of Nistune stuffing up and if you want to return the car to stock you can just put all the settings back to standard if you can't remove the nistune chip.

[Stagea_Neo]

nah haven't bought it, probably cost about $80 bucks if i do. i'd prefer to be sure.

was thinking of nistune, maybe the rom can be overwritten with that of a 4wd auto rs4.

just had a look on fast, they are both for a RB25DET 4WD Auto S2 Stagea. the only difference is the production year. but i dont think this will matter on the S2's. it was just the S1's that had the different ecu pinouts between the year models.

Wow for $80 I'd grab it... looks like the ECU on the right is an earlier version (going by the large version number up top), and being the '98 one that would make sense... Haven't read about any wiring harness changes for S2, only about 3 different versions for series 1. But knowing Nissan, they probably shifted the whole plug one pin to the right or something like that

Surely this '99 model ECU from a S2 NEO engine (yours *is* a NEO isn't it?) will work with a '98 NEO engine?

However like Robert (KiwiRS4T) I agree that the Nistune is pretty reliable (had mine done nearly a year ago) so doubtful that you need another ECU (unless it is to save a few days downtime while you wait for the express post). You can send your ECU off to have them install the ROM chip professionally and pre-load it from your ECU and have it ready to plug-and-play for less than $500. In the manual there is a procedure whereby just swapping a couple of jumpers the new ROM is bypassed and the whole thing is back to factory original.

[Stagea_Neo]

yeah mine is a neo.

thanks for the info/feedback guys.
