Is This A Standard Ecu

see in first pic, bottom left, you can see the edge of a chip underneath that circuit board. That's the rom chip (28 pin rom), if that is soldered onto the board, then it's a stock ecu (well probably), if it's a socket, then it's definantly a remap.

Must be a stock ECU then merlin, which if what i read and my limited brain power. Would i be right in saying the RB 25 AFM having a larger area would induce a leaner fuel mixture as the ECU would be mapped for the smaller GTR items.

Therefore with a standard ECU and their rich mapping it should be a some where in the ball park, again it needs to be checked if i ever get the F%$#ing speedo 6 weeks now sinse ordering.

ok...

^ this is stock ecu (actually this is rb20det, but they are both similar) with the top board removed.

the chip circled in red is the ROM, if the rom is soldered to the board, then it is a stock chip. (mine stock ecu chip has MEC-R126 8RY108 written on a silver sticker on it). If your chip is in a socket, then it is rechipped. Often re-chips will also have a sticker with a tuning shop on them.

Nope thinking it is a stocker chip

Part number is MEC R282A 8RX1D-04 on the chip that is.

By the way have you seen one of these items as i wonder if it would be ok for me if i installed a Pfc then i could do my own tuning as there is just no one here set up to do this.

Yeah, the Blitz ECU's have the chip in a 'bay' with a hinge, so it can be easily removed and reconnected. This allows you to cycle through different spec chips, or reprogram the chip and reinsert.

I would say that ECU is stock, and I'm not sure about the possibility of modifying an ECU without changing chips.

      R33 GTR running -9 with no tune

      By Duncan · Posted

      Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.

      Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it

      Coolant leak?

      By Duncan · Posted

      Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground

      Coolant leak?

      I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.

      Is it alright to top up with just another green coolant?
