Can Someone Tell Me If This Ecu Is Chipped Or Not Blitz

I would say it isn't chipped. It could be, but if it is, then it has been done in a most unusual way. When you chip these ECUs, you desolder the EPROM (it's the rectangular chip in the top right corner of your photo) and solder in a socket. Then you can put chips in or pull them out without risking more soldering on the board. You can see on this board that the chip is soldered directly with no socket. Now, it's perfectly possible to do that, just unusual.

Having said the above, if I were a Blitz or a Mines and I didn't want people to be able to steal my "tunes" so easily, then I would solder the chips in direct. Make people work to get hold of the info in them.

Now, having said that, the sticker on the EPROM looks like the original part number. The sticker on the lid of RB26 ECUs (and others of the same era ) has codes like MEC-R580. Yours has MEC-R280. I'm not aware of the difference, but regardless, it looks like a Nissan chip.

FWIW, I wouldn't run any engine on any stock ECU with a Jap tuning house chip in it. The Mines ones are all time bombs. Blitz can hardly be any better.

this is what a chipped ecu looks like with the chip removed.

there is a socket put in its place and then the chip goes into the socket.

that ecu you have has not been socketed, the eprom is directly fitted to the board.

      Duncan's V37.......race car?

      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.

      Jacks that fit under GTR lips that can reach the subframe?

      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.

      BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
