Dude...

Im working on your map,

I see your running a Z32 MAF what size injectors are you running? And what make?

Do you have the latency of them? Also you need a wideband to get the idle just right

Thanks FB.

The map you send me is great, when running.

Only problems now is , struggling with idling, it keeps dying when i close the throttle on deceleration.

Probably before tuesday i will have my Wideband!!.

Good to hear...

That Map is just a base and you will need to tune the K value once you get your wideband.

With the deceleration thing, Do you have a BOV and does it vent to atmosphere? If so there is your problem se if you can set the spring tighter also add a about 10 degrees down low this helped with Nizan-R’s car.

Please also check if your BOV is open on idle

Thanks glad I could help


Forgot to add, I have a revised timing map that should help the boost come on earlier with your turbo

PFB, yes my bov is recirculated, where should i add timing, on main timing map??

Any ideas about deceleration timing?
Matt said maybe by adjusting TTP min could also help!.

This guy with gt30r map, what fuel and how much boost did he run??
(It must have been high due to load scales)

If I cant fix the idling, maybe i should try moving my Air flow meter infront of throttle body??

Thanx, so far so good, send me that timing map!!.

So you are using a recirculation BOV? If so the BOV isn’t the issue.

When you get you wideband, I need you set you whole map to 14.7 and tune the K value and injection latency till the engine hold 14.7 at idle , Don’t drive the car with the map set at 14.7 of you will blow the motor.

TTP min could possible solve the problem try increasing the value to link 26 from 600rpm

(It must have been high due to load scales)
It was, around 19Psi , I need you next time to log the data from the Nistune system and floor the car in 3rd till redline then look through your logs and get the highest TP load number , This will allow us to rescale the fuel and timing load maps to get better resolution, You can also send the logs to me and I will rescale the load maps.
If I can’t fix the idling, maybe i should try moving my Air flow meter infront of throttle body??
I personally don’t think this is a good Idea , I don’t have an issue with my Z32AFM…
How close is the AFM to the turbo?

I just want to get the fueling correct before I send you the timing map, because its very aggressive

PFb, thanx, i will do that once i have my wideband.

I have resolved my idling issues etc, Z32 was to close to turbo, I have moved it to inside of front fender, the only way i can get the pipe longer.
(When it rains, so close to road water might be a problem).

Only thing now is it smells very rich when running!!.

At what boost should i do logging and which 4 parameters ??.

Pfb, another question, once i get my K value and latency right, do you think it will be okay do drive it for about a 1000km at a max revs of about 4000.

Because my motor is newly rebuild, and my racing clutch needs to be run in, and my new brakes.

I dont want to punish it before a 1000km.

Had my intake in my fender for almost 4 year now and, I have never had a problem

I did set the map up slightly rich; You can tone it down once you get the wideband

The nistune system logs all the parameters, It just displays the 4 you have selected

Should be fine, it will allow you to work on your low end cells and sort out you fuel economy

Pfb.
Thanx, once I pass a 1000km i will send you the log!!.

Sometimes it still dies, My Z32 afm in front fender is open to incoming air from the front, is it ok or should I shield it from direct air flow on it??

My z32 afm is Vertical in fender and get air on one side!!
(Wont the extra air disrupt reading)
