Connecting to NIStune with no motor in the car?

Post by Gotenks64 »

Hello Everyone, I have a quick question. I installed my type 3 board in my 1992 s13 Auto ECU for my KA24DE. I moved the jumper with a little piece of wire to connect CJ1 to CJ2. I don’t have my motor inside my car, yet I have to wait to get it from the machine shop in a few days. I cannot connect to the ECU though, the drivers are installed properly and the green limit blinks for transmitting a signal. Should I be able to connect with just the ignition on, and not having a motor/started?
Also When I run the car for the first time is there is where I figure out the onset of boost to see at what level my motor transitions form Vac to Boost? I learned how to tune on Honda; so having load in place of Vac pressure is throwing my off!

Thanks!

Bit hard to tell from the photo but it almost looks as though you've put the jumper from CJ1 to CJ2 instead of across CJ2.

In your photo the jumper should be horizontal.

nothing fried thats the ECU internal/external line... if you had done the other side then you would have shorted GND and 5VCC together and fried the 5V regulator

ok, Thanks all. I figured it out. The ECU was not getting power from the chassis plug. I also jumpered CJ2 it it works. Thanks!
