S1 Stagea Ecu

[whitenight27]

yo would any of u guys know if a r33 gtst-4 ecu would fit a s1 stagea?

i have been told there is only 2 pins that are diff. but not shore about this

[QWK32]

even though the S1 shares the same engine as the R33 models the ecu has a plug the same style as the R34/S2 ecu's. also to that, of the S1 ecu's there were 3 variations used, i think some of the guys have just plugged in R34 PowerFC's without a problem, while one of the year models is a pain to replace, the ecu's pinout is a fair bit different to the others. if your after some better info you could ask SAU members GoldZilla or Duncan. both have S1's and have had experience in upgrading/replacing the ecu's.

kinda curious about this myself IF I decide to go down the modified route or not.

(thread subscribed for this reason alone.)

nistuned Z32 ecu is the go for a S1, wot is your purpose OP?

did you do a GTS4 stag engine conversion chris?

[wolverine]

There are three pinout configurations on the S1 stagea. You need to know which one you have before committing to an ecu upgrade.

Choose wisely.

yep mine has a Auto C34 4wd RB25 in it. auto box long gone - grey plug on the ECU harness. need to get it working on that harness first then I will consider 'fiddling' with it.)

[dirtyRS4]

It can be 23740-0V300, 23740-301 or 23740-302 for a series 1.

this is confirmed in the nistune parts listings.

I've got a Z32 ecu with nistune and adapter harness for an S1 Stagea that I wont be using if anyone is interested

I've also got an R32 ecu ready to be nistuned with adapter harness for S1 Stagea

Do you have photo for adapter harness?

Who made it?

[too_much_boost]

They are both custom made. The Z32 ECU version uses a field harness extender with the Z32 ecu loom spliced in and the R32 one is full custom. The R32 one was made by some workshop in NZ

[Toshi]

How much is for R32 harness?

You guys might find this info useful! (only 3 ecu's on c34 stageas', RB25, RB25Neo, RB26) *S1 RB25 = pita!

Stagea ECU diagrams

Z32 uses a different ecu to the s1 stagea, as does the R32 & R33 GTST (all similar to RB26DETT, single afm is the difference) , the R34 RB25DE & Y33 RB25DET Gloria uses the same ecu as the s1 RB25DET stagea (fyi: the 98-00 VH41DE uses a very similar ecu)!

Worthy of noting is that the neo pinouts are very similar to the s1 ecu!

There is no nistune for s1 ecu!!!

ok cool info

what do u all think or know about ems 4860 ecu?

i am looking at that ecu or a greddy emanage ultimate. what would u think would be easier

4860, you would have to batch fire injection and ignition as it only has 4 drivers of each, not really a big deal. the 6860 would be better as it has 6 of each. why are you interested in EMS? i'm not bagging them out, they just aren't the most popular ecu in the RB world.

Probably should ask first if you have a manual conversion done? if its still auto you should definitely go the emanage route, you could try and piggy back any aftermarket ecu but the emanage is the best fit for the job.

[whitenight27]

i was asking about the ems 4860 because i have a friend with a second hand 1 i can get off him for 500.

it has been fitted to a gts-4 but i would just use it as a piggy back to mine.

yer i am still running the auto

[BensDR30]

The auto ECU is part of the main ECU - it must remain and be intercepted/piggybacked for a successful outcome.

[whitenight27]

yer i know all about that so annoying lol.

that's why i trying to find out what the best piggy back would be.

a workshop hear in Perth is trying to get me to buy a heltec platinum 2000 there ok ecus but its like 1850 for just the ecu.

u can get greddy emanage for half that

[SL33PYRB]

Can anyone bring this topic back to life with their successful outcomes. I have a s1 c34 rs4 still auto. Wondering what I can do while keeping it auto

[too_much_boost]

My successful outcome was sell the S1 and get an S2 (which is easily nistuned)

You will likely need a custom loom and run a second tunable ecu in parallel to the standard one which needs to stay for the auto
