Apexi neo set up??

[drifting_changed_mylife]

ok so i got the apexi neo on my car and i have no idea how to work it.:newbie :


i need help selecting the right settings for my sr20 set-up. i also need help navigating the fucking thing. if anyone has some sort of insight on what air map setting ext would be best for my set up it would also be greatly appreciated. helping me navigate wont hurt to.

my set up:

s13 sr20det
550cc inj
top mount t3 turbo
spec stage 3 clutch
sard fpr
walbro fuel pump
fmic

HELP ME PLEASE!!! i need this car running.. i was gonna get a jim wolf ecu but times are hard........

oh and a 300zx maf..........................

With the Z32 Maf you need to go 2 in 6 out on your Hotwire settings.

Your also going to need to adjust your fuel %. If I were you I'd sell the AFC when you get the chance and get an Enthalpy ECU. Your timing is going to be messed up running the fuel adjustments its going to take to get the car running. Also you really need a wideband if your going to get it running right, or a dyno.

The AFC is a Bandaide but, if you know how it works you can use it to your advantage period. That being said settings for a setup like yours is 4 arrow 2oclock, 2in 6out, low correction 30% across the board and high correction leave alone till you have a wideband, then adjust accordingly. Every car is different, so...

Your timing is going to be messed up running the fuel adjustments its going to take to get the car running

I still get a kick out of this every time I see it, I blame John, and Steve. J\K

DO you know how the AFC works? By tricking the stock airflow signal, and by doing this you are telling the ECU you are at a different point of the timing map. Which does make the timing off. Have you ever tuned a car before? Even one degree of timing can make a difference, more so as your HP increases, I've gained 40hp with 1 degree. Are you saying that changing the airflow signal will not effect what timing cell its in?

[cotbu]

That post was not an attack calm down, Yes I do know how the afc works and yes I've tuned a car before. 1 degree of timing can but most likely, not make a difference. No I'm not saying, that changing the airflow signal will not change timing. What i'm saying is that people repeat what they heard but don't fully understand.

The OP threadstarter, can use the afc to get his car running with the 550's and not flood his cylinders. Yes,he can drive the car and not waste a tank of gas in 24hrs
blowing his engine that can still happen, but he didn't ask for help with that.

1.My question for you is, do you think that every point you could possibly be in, in the map has a physical cell based on tp? Or does the ecu calculate when your between cells?
2.Which way does the timing go when you add fuel?
3.Can the afc trick the ecu into believing it's not there....when it is?

I'm not saying the afc isn't crap... I'm saying it works just as it's supposed too.

PS I'm not advocating the use of afc in fact I have a dyno graph with a dip in torqe because of the afc, but it's my favorite
It was zeroed out but the throttle percentage was still set and that's what I believed to be the problem, the next run was without the afc and dip was gone but i'm still not sure.

Your very right that a lot of people repeat what they have seen and heard, thats why I am trying to help the OP understand that tuning/tricking the ECU is not the best way to tune. Not saying he shouldn't use it just trying to help him and others understand what its doing. I didn't say it will blow his engine up or change power drastically, although depending on the tune and boost the timing values can be more than a degree or two off. Your right thats not going to make a big difference on his setup but on some setups will.

I didn't take it as an attack just don't want people to think the AFC does not effect timing because it does. It takes the airflow signal converts it to trick the ECU into thinking a different amount of air is entering the engine. And no I didn't learn this from Steve ha ha. If you set the airflow to -30% the higher airflow the larger the differance in voltage and the farther from the correct cell. The cells are not based on throttle position but on load(Airflow, temp, etc.) and RPM.

Timing can't be said to go one way or another by adding or subrtacting fuel because it depends on what the voltage is from the maf and at what rpm. Telling the ECU to take away -30% fuel you are telling it that there is 30% less air at some rpm levels this will not matter and it will run the same timing, at others it will add timing.

You can make the ECU think the AFC is not there its not perfect but you can. There will always be some noise added from the extra electrical device that will make it not 100% perfect but you can set it close to not modifing the signal. I know the AFC works like its supposed to and I use one myself, I just want people to know that by modifying the air input signal that you are changing the load cell the ECU is using. Small changes won't make any difference but as you add air and modify fuel it will become farther away from the correct cell, and these cells are what makes timing adjustments. Sorry if I cam off like a jerk, just trying to be helpful and thought you were saying I was just a follower of some members that spread miss information. The fact that changing the MAF signal does effect what the timing is however is true, will it make a differance on everyone's cars, no but its not the best and will make some although possibly small differances on most cars.

how much power do you put to the wheel with the neo

What the fuck are you doing bumping a 2 yr old thread? PM the OP!!!
