For Idle ignition control, is there a map on it or anything? Cause i just see the option on and off

Yeah. Stage 3 hkscams 264 intake 272 exhaust. There spread the lobes 2.5 degrees retarding intake and 2.5 degrees advance exhaust on jwt cam gears. Also granted its a cool 75 drgrees where i live. Yes map is calibrated. Does a twin plate orc mess up the idle as well?

Coming out of the neck is about 80c and after radiator its 154F....... have a high capacity clutch fan and a 3 row koyo rad witha 1.1 bar cap

Yeah thats my next step, but it has some coolant hoses and I gotta get a block off plate and all that.... never look forward to messing with coolant

So I fully shut it and it still does the same thing... I found an old thread to help me check continuity in the IACV to see if I am getting a signal to the ecu.... In general I wonder with all the aftermarket cooling, I am thinking the IACV doesn't really work. Reading through the manual, the coolant temp is 174F is considered as "warmed up", but with the cool california weather, running distilled water only, and more efficient fans with the stock clutch fan, I will only get around 155F. Under hard driving I would only see about 165F usually. Could this be a factor? Nissan's have this valve that use some wax thing to dictate how much air to let into the intake. This valve bypasses the throttle butterfly plate and goes straight into this valve. But like I said, "warmed up" is considered 174F, but I am usually way under that for light loads.

C Ahhh got it.... My tuner suggested I open it, but didn't tell me to recal before trying again. I will give it a try.... Should at idle, the throttle plate be completely shut?

HI LinkECU, I am at wits end and so is my tuner on this idle hunt issue. Vacuum has been smoke tested and timing has been verified on a timing gun..... Any help would be appreciated.... On warmup and enrichment, it is normal, it just doesn't ever settle down. Logs and Tune attached. Any help would be great... NissanS13nonvtc-S14-15-G4X-Ken-yu-8-29-23 (2).zip

@Adamw Its reading 4.01V I guess by default it was 4V limit..... I raised it and its fine now. Didn't know it was an automatic fault temperature....

Also i am still using the fuel level guage in my stock dash as welll so not sure puttimg coltage on it will mess up anything?

8 2 hours ago, Adamw said: What to you mean by that? What are the error values set to and which one does it exceed? Yes that is what a pull up does, you are effectively creating a voltage divider with a fixed resistor on one side(100ohm), and a variable one on the other side (the fuel level sensor), so your variable resistance is converted into a variable voltage output.  Its saying 212F. Its just completely not reading correctly. Any idea how to troubleshoot the sensor? I guess the question is it wont do anything to the leveler or fuel pump hat if i put a voltage on it is what i mean Thanks

Hi All, I have an IAT from LinkECU and recently its starting to register out of range throwing an error. I test the 5V on the senor wiring and I test the grounds and they are all good. I have 4 sensors on the same 5v and ground and none of them are having issues. Do you think its a faulty sensor? Also I have a standard nissan resistance based fuel level. I want to send that over can to my dash. I think @Adamw wrote a schematic here, where I use a 5V to a 100ohm pull up to the level sensor wiring and filter it to the AN VOLT input. My question is wouldn't that electrify the entire circuit leading to the pump level or it doesn't really do anything?

Hey @Adamw Quick question. Since i am still using my stock Nissan dash fuel gauge, can i just pull a 2nd wire from the fuel sender? By putting 5v down on the 2nd line wont it electrify the entire chain back to my stock dash?

You are right that was it..... So wiring and a couple of settings did it. I was using the PDF and the pictures weren't as clear as the one you posted for the Pinouts. Thanks all now tuck everything and bolt / suspension checks and off to the dyno. I want to hit up Jason @ Linkecu in Oregon to see if he will tune it. I know he used to run PSI there and I always wanted to get a tune from him..... Thanks again Adam!

Here are my can settings and the tune.

Just did the continuity. Looks good. Does the ground from the sensor have to go to pin 1? Mine i just going to chassis ground I got it to work woohoo. The CANF wiring was backwards. Setup and ready to go. Quick question why am I not seeing the afr after everything is setup? It found the lamda sensor and all
