Create your own 5V supply with caps and regulator.. The 5V in the ECU runs MAF and TPS .. IMO I would keep all IGN away from those sensors.. Nor add any more load to the ECUs VREF 5V.. Just a thoug...
I had this same problem when I was in my late teens. My doctor gave me a shot and told me to stay away from trailer park girls. :bigthumbup:
Here is the latest board. Ive been working a lot on making it as small as possible, and this is pretty much it. Its just under 2 square inches. But a glitch has me bound up at the moment and I am w...
Rock solid boost control now, worked a treat with the GTIR ecu and GTIR base file.
Thank you Dave ! This schematic helped me out ! Now i have flat shift :bigthumbup: and i need to lern how to drive with that !
They will be coming very very soon.
Dave and I have both been testing them in our personal cars to ensure that the functionality stays the same or very very close to the V1 boards.
A lot of t...
COP is already done with the S13 ECU.
I love my NEMU, I have converted to MAP and love it. Very easy to tune and does everything I need. Great ECU.
It has so many features that you would find in a stand alone. For a street car, or even a race build I can't see needing much else. The feature list is insane. Change fuel/ignition maps real tim...
It dawned on me this morning I never updated on how my finals went. I received and A on the project and an A in the class. My professor was so impressed he had the dean come down and sit through th...
Yes you can with one of the programmable outputs. NismotronicSA is an excellent ECU to use.
You can download the software demo on their website. It gives you an idea of what you will be working wi...
Honestly, you shouldn't even consider any other ECU. Nismotronic is the best by far, and John is super helpful.
I feel like every post I've made here lately is about the TPS :)
Readings on ground pin:
0 Ohm resistance to ground
Readings on signal pin:
Throttle fully closed 0.45-0.55V
Throttle partia...
First pic is of just getting the DIS-SR running on the "bench" and the corresponding oscilloscope image. I lose a channel on my scope and the triggering is kinda slow. I need a new one bad.
The v...
That last pic of the harness looked so unprofessional. Heres a better one.
Hello Monder, what an excellent choice you've made to go with the Nismotronic Speed Density solution.
All factory SR20 engines come equipped with a knock sensor. If you are unsure about detect...
I kept it in just reduced it so its not so crazy. Tune is getting better and I was able to get my idle back to 900 RPM. All of the idle pulsation is gone. Now that the table is starting to smooth o...
Sorry for ma bad english , now is all clear, i simply misunderstand what John wrote in her post. Now i setup Ignition max retard to -(minus) 16 degree in Ignt Tab / Advance settings and AntiLag wo...
UPDATE:
So after figuring what latency for the 800cc injectors, I inputted them into Nismotronic and alas, the car still wouldn't idle. So with this, I sent John my file and low and behold, I was ...
Yeah. I have a gear attached to the distributor where the cam key would be. Ill be pulling the tach signal from the distributor and running it back through the arduino for the LCD display. Once all...
Engine simulator part two. The display system in now partially operational. Still need to work out the POT percentage scaling. But for the most part it is functional. Now to mount everything and ru...
Engine simulator build part one. This is the control system for the simulator. I am using a 2500kv brushless motor and 12a esc. This is a much mor efficient method of motor control. Part two coming...
Most of use here are running FWD cars. Our ECU's do not support the EGR temp sensor so we are forced to use the break out box.
I personally use the 5v output on the break paired with a 4.7k ohm...
I was a little reluctant about posting my board, but considering this design didn't produce the best result and will likely meet the chopping block, I think its ok to share. This was made using a t...
Once I have a suitable motor picked out I will begin building an adapter to couple the motor to the distributor. This is the basically how it works though, although the inputs and outputs have not ...
