Nistune Forums

I took it all apart today to inspect it. turned the key and moved wires and wiggled plugs making no difference. Everything is working fine. Started right up. So I will have to wait till it messes up again to fiddle with things.

Can I use electrical grease in the plugs to keep the connections good and moisture out if there is moisture getting in?

I will try what you have stated above. Supposed to rain all week, so it will be a good test period. As for the kind of Nissan I have. Its a 1973 Datsun 240. It have a 1981 280zxt FI and ignition harness modded to run the z31 ECCS and MAF. I now am running a z32 MAF with the Nistune. Only thing stock...

Its not getting into the car. The ECU is on the drvers side kick panel, I would know if it was leaking in. This can happen if the car is in the garage also while its raining or had been.

I am having a problem. If it is raining or had rained during the day, my car will start like its fine, and then the blinking lights on the ECU just stop and it will not idle, becomes really hard to rev, and has a strong gas smell. If I let it die, it will not restart. Now if I let it sit for a hour ...

Had to have been a bad burn like you suggested. ECU is doing fine now. I just started over. So I guess I will re select my options and adjust some stuff to get back to where it was running good.

before I posted I took the chip out and re installed it, then I got lucky and was able to reburn the tune. I went to get a video of it tonight and it is working fine. So I guess the chip was loose or a bad burn. BTW, I dont have the stock chip. This ecu is one I bought off Jason (RedZ31) this was th...

Ever since Friday, when I turn the key to the on position, I can here my fuel pump relay resetting very quickly to where it sounds like a machine gun. So I unplugged it and looked at the z31 ecu lights inside and they are doing the same thing. Played with the harness to see if it itself was shorting...

No, after changing the multiplier it is running good with no timing issues. And yes, I need a wideband. Gonna get one soon. I dont know if it was related to mixture. I know sometimes it woud go into the "lean" area according to the narrow band, which really means little.. but i could feel ...

So after hours of reading this forum, I think I narrowed it down to an error in my math for the injector multiplier. I changed that and went for a drive around the block and it ran fine. Tested the load on boost and got it sideways no problem at 6 psi with not cut outs. So I guess I will get it plat...

No help available? I am wondering if it is because I am getting my MAF power from the coil. IF it is getting some kind of interruption.

Here is the link for 3 logs and the bin file. Looking at the timing and it just randomy falls off at points.

If I accelerate normal it will run fine. Soon as I nail it, it gets into boost, car dies, tach goes to 0 for a second, and then it will come back to life, does it one more time, and then pull to red line like nothing happened. Is this a NIStune related problem, or a car problem? On a factory eccs wi...

Thanks. Sorry I'm dumb. I know I am making this way harder than it is supposed to be.

I feel so stupid. I have read so much over and over.

I guess I need this spelled out for me. So this resistor is connected to wire A, and is grounded with the sensor ground D? Or is it on the ECCS side.


Is there a picture of this?
