I did as much reading as I could and just need someone to simplify some things for me. I have a plug and play ECU for my 93 FD. It is a heavy modified single turbo engine setup at the moment. Things that are relevant are listed below:

1. OMP is removed. Connector/Harness still currently installed with main engine wiring harness.
2. Single Turbo...ie, no twin turbo controls needed.
3. No A/C or PS
4. Idle Control Valve still installed
5. Innovate MTX-L Wideband W/ Serial Cable
6. MAC Valve Boost Solenoid (Utilizing Wastegate Control Output from ECU)
7. Using ECU internal MAP sensor
8. Fuel Temperature Sensor removed
9. Setup for Direct Fire


I am trying to accomplish the following:

1. Install/Connect Fuel Pressure Sender to ECU (for uses of engine safety)
2. Install/Connect Oil Pressure Sender to ECU (for uses of engine safety)
3. Install/Connect Oil Temperature Sender to ECU (for engine logging/safety)
4. Possibly activate a relay that works for my water injection...this relay would just need to be triggered at a specified boost pressure ex. ECU sees >10psi and triggers relay. Maybe I have a spare output that could be programmed for this?


If I am correct, I can use the wires that would have went to the OE Fuel Temp Sensor and use them with an Aftermarket Oil Temp sensor. If so, great.

Now I have read that using an Innovate SSI4 is a solution for getting aux signals (oil pressure, fuel pressure, ect) into the ECU to be used. I was curious if I need the SSI4 or if I have any unused/spare pins on the ECU that are not being used based on my above listed setup. I was hoping I could use my wideband directly into the ECU serial IN and then use any normal ECU pins available to input/output the other requests I have.

The pressure sensors I was looking at using were the following (for oil and fuel pressure):

Thanks in advance to anybody who resonds

 

I was going to do the same thing my self. I found a writeup on it for one sensor but not two........ Cant find it now but it is out there.

I wouldn't blow money on that sender BTW I got one the same off ebay my tank had e30 in it, it sat for three days next time I started the car fuel was pouring out the pins.

 

I have basically the same setup, but wasted spark. Aux 1-4 are your high current outputs, 1 for me is a fast acting soleniod to control meth spray pattern, using fuel map 2, so the pump is always at 250psi above 10 psi. Aux 2 is the idle control, aux 3 is the mac valve. Aux 4 feeds a relay for the meth pump, which is activated on 10 psi.

The rest are low amps or logical outputs. I.e. Led for Launch control, logic for meth system.

Now the inputs is where you can go crazy, I didn't do what you trying, with the oil temp, pressure etc, I have them go to a simple vector board that I built that sends a ground signal to ecu and essentially switches to a fuel/ timing map that only allows the car to idle. You can reach out to adaptronic direct and mark g will get right back to you (Australian time however).

 

Mps Hell....thanks for the heads up on the shitty sensor....looks like the only other alternative is over $100. :-(

qqqqball, thank you for your insight. It makes a bit more sense to me now and I will try to get a hold of adaptronic.

Thanks

 

Got this reference from a couple people here on the board. I purchased a couple but haven't used them yet so no feedback.

Any feed back on these sensors?
