Quick check, the pin 18 on the S14 SR20 ECU (69F00), the Fuel Pump Relay output. It is pulling to ground? Meaning you hook one side of the relay to some switched 12v and the other side to this ECU pin? I guess I should just ask, are most output drivers on this ECU (except #25 - WGA) pulling to ground?

Each fan lo/high has an output driver to drive a relay. So does that mean that the low and hi relays are not triggered ON simultaneously? The reason I ask is because the Altima dual fans have 2 circuits going to each ones and the way it works is that if one circuit is powered on each, they will run...

Yes I fully understand that. My plan was to purchase a Type 3 board and software. But since there's already a tune for my setup in there, I was just wondering if there would be any way for me to read the maps (fuel, ignition, etc) that are on my daughter board so that I could possibly transfer them ...

I will be wiring some Altima fans and was looking into getting the ECU (69F00) to control them using the feature pack. I have a couple of questions though. Those ECU pins pull ground right? If so, is it safe to have them drive a 30A Nissan relay that is connected directly to 12v power on the other s...

Could you confirm/link what adapter I would need? I'm ready to put in my order.

Are you sure I need an adaptor? It looks like the typical 2x20 plug the Type 3 bord uses to me.

Here's my actual ECU:

I bought a 240sx with an S14 SR20 swap. Mods are: Intake, stock S14 SR MAF, BOV, IC, STI injectors, HKS GT2530, 3" turbo back exhaust, AEM fuel pump. The previous owner said the car was tuned with Nistune. Unfortunately when I opened the ECU (69F00), I found a generic daughter board installed. ...
