Hi fellas,

I am goin to do a Nistune soon to my R34GT-T, upon opening the ECU cover this morning, I found that it has JECS written on the ECU, so I am wondering is that a Stagea one or what?? Please see pics.

Does the ECU look tinkered (dunno what previous owner did) or stock??

thanks,

Ron

You could be right, my car doesnt rev to 7000rpm, but instead it cuts to around 6800rpm, could the SAFC or rev/speed meter be the reason for this??

There are no physical meters/ gauges in my car apart from the aftermarket boost gauge, so you saying the SAFC or whatever was removed?? What makes u say somethings been added at some stage?

cheers

Actually its not standard, its a stagea ECU according to Matt from Nistune - I know they are almost identical to the r34ecu, but Matt said its a stagea one - quote :

'ECU is from a S2 Stagea 0V812 (JECS)

If this is installed in an R34 GTT then for some reason the original ECU has

been swapped. Is the car auto or manual? Stagea are auto'

thats a S2 Auto stagea ecu. mine is the same part number. also the reason why your rev limit is lower than expected, the Stagea's rev limit is 6600rpm compared to a manual R34's of 6900rpm (values from a standard rom). As wolverine said it wont be a problem if your planning on installing nistune, they are both type 4 boards, the only thing you wont have is traction control. you could ask Matt if its possible to load a R34 base image to the nistuned stagea ecu and have everything work as normal.

thanks Josh, u have solved my rev limit problems! Now I know why it only revs to 6600-6800rpms - the GTT goes to 7000rpms.

Ordered the Nistune and asked Matt to load the ER34 base map, so hopefully that problem is gone when tuned. He said its ok to

load the R34 maps onto the stagea ecu, and now I also know why I dont have traction control..

Faarrk who was the idiot out of the 3 or so past owners who put the stagea ecu in my car..!!

    • This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.
    • Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
