SOLD. Thanks.

It was really a desire to have a programmable ECU and not having any other good options out there.

Rails have been sold to a semi-local NSX owner. Thanks as always for being a great community.

I am not sure the brand. I bought this more than 10 years ago when I was in Japan. When I had my SPG mounted, the bottom of the seat was all the way touching the carpet of the car. Couldn't be any lower. Eddy Sent from my iPhone using Tapatalk

I guess I will try eBay. Thanks!! Eddy

Admin, I have a 91 5 speed transmission which was bought in Japan and imported to the US. The serial number sticker was missing since I bought it. Now I like to sell it but I am aware there is a rule about serial number sticker. Can an exception be made if I clearly explain it or is there...

Unless there is a valid reason, EGR should not impact most of your driving. In fact, at idle and at WOT, the EGR valve is not even open. It's only in operation mostly during cruising under medium load. See this EGR valve lift map from a 91 MT NSX. The cursor is highlighting the idle...

Then I think the other guy you talked to is right. It's probably debug code writing to an address that was inserted during testing but removed in production ECUs; they forgot to take out the code. The 0xDB you are reading is probably undefined value on the bus when you address it. What kind...

If you like, you can always program the ECU to not run the EGR. I was dealing with a high NOx issue on my car and was able to increase the EGR lift by modifying the ECU ROM's EGR map. You can set the whole map table to 0 in effect disabling EGR. Then you wouldn't have to change anything on...

Hi Matt, Just giving some comments for now. No progress made yet since the last post. NSX ECU's MCU mode select circuit is also in the upper left corner (see the area around R424 in the diagram I posted). So I do intend to install some jumpers to mode change on demand. I still can't be 100%...

Hi Matt, I have spend a few nights mapping out the RESET circuit for the MCU. On the NSX ECU, the RESET line is tied to ground so when the ECU is powered on, the MCU goes into RESET and stays in RESET. There is a transistor (Q400) that ties to the RESET line which is controlled by the backup...
