Ok so today i tried to reset my idel, to get the timing correct.

I tried to do what the manual said to do and the guides on here.

Ok warm the car up. Turn off, disconnect the TP sensor, turn the car on, idel is at 1200 rpm, so turn the AAC valve, all the way in, and the car only came down to 900 rpm. Reconnect the TP car rpm drops down to 650. HUMMMM

OK so what is going on, is it suppose to be, i can't sent the timing as it has to be done at 650 rpm with the TP off, but i can't get it that low. Will cleaning the AAC fix this, i have no idling issues, but i am a bit warried taht something is wrong.

HELLPPPP

somone point me in the right direction.

i want to do my idle properly, and same for the timing, and timing seting is rpm dependant.

SO i can't do it properly.

From reading other post, once the TP is off the rpm should drop, but mine rise to 900 rpm and i can't get them down anyfurther.

Ok so here it is then

I turn the car on this morning and still acts thesame, cold start work fine.

Why can i not get my AAC idel screw to bring the idel lower then 900 rpm. Also fideled with the computer screw, and nothing, doesn't make it go up or down, with or withouth the TP set on.

HELP, i think i am going to go insane with this car, everytime i think i have it sussed out and all good, something hapens or i find soemthing new that might not be thesame.

booohoooooooo.

read the thread on setting your idle correctly.

there is also a screw on the ecu yo uneed to adjust usually.

You could also have a vacuum leak, vac leak caused my car to idle at around 1,200 or so

my car idles at 650 rpm, but when i disconnect the TP it sits at about 900rpm, the computer screw does nothing. The thing i am trying to do is tha the base timing is suppose to be set with the TP off at 650 rpm, and i can't get that to happen.

SO i need some help.

    • Everyone is too used to learning from places like HPA "how to tune" and what to expect at what point, rather than being able to see "The computer says I'm in cell with Row = 8, column =4, and I can see my fuel is lean, so lets add more" Everyone wants "real units", which helps for someone picking it up for the first time and seeing how bad the tune is if they're not used to touching it.   However, I think for most of us who want to play with it, you're 100% right, we're only needing to learn about it for OUR CAR. Which makes it great, and we don't need to care what the real values are, we just need to know which cell it is, that's causing the lean or rich point, or that we want more ignition timing or less. But again, everyone wants everything super you beaut and nearly self tuning, with VE maps, and a billion compensations...   Though then there's me over here when I'm doing reverse engineering work just reading data in hex format that most people couldn't work anything out from. Yet I can see what's going on.
    • Um. No. Since Matt introduced the TIM it has become a lot easier to deal with the consequences of changing K for AFM and injector swaps. Then, tuning is a f**king doddle. No-one needs to know or care how many grams of air are flowing or any other bullshit. Need more fuel in a cell? Add more fuel. Need more timing in a cell. Add more timing. Need to adjust any of the other tables for warm up and so on? No harder than anything else. Sure - it's not an ECU system for starting from scratch on an arbitrary engine. But then.....it was never supposed to be, not recommended for, and almost never used that way. So.... On your engine, in particular, Nistune/Nissan OEM is about as sophisticated and difficult as banging 2 rocks together. Those ECUs are primitive and simple. There is nothing difficult there. I learnt Nistune from scratch, created new maps with extended axes, interpolated/extrapolated the original maps onto them and tuned my RB20 (basically the same ECU as your 26 ECU) all by myself, more than 20 years ago. And that was long before even TIM.
