Default ITB + NB + Adaptronic

Hi

Trying to work with ITB + Adaptronic on my 99 NB.
I have some maps for boosted NB but does't work on my car.

Only go "smooth" when its goes very rich, as soon as I adjust the AFR to near 14 with fuel master trim it's go wrong.

When I kick the accel pedal, it rough and rev go down, like as no fuel, and then rev rise up.

So if anyone has 99 NB's Adaptronic map, please post it to check how it's tuned.

My actually set up at NA.

99 stock NB engine
RX8 yellow injectors
FujiRacing ITB + Plenum
Stock fuel rail + stock FPR

P.S: at idle it's go 70kpa, wondering if I need adjustable FPR

Please HELP!!!

Using throttle position or MAP signal for fuel?

If youre trying to use a map signal you better have a vac manifold and restrictor in the line otherwise its hopeless.

First of all I tryed with MAP signal, using vac manifold, using this one.


I put motorbikes gasoline filter like a restrictor,



But few hours later, the gasoline filter was destroyed by the motor heat.

So now I'm trying to tune with only TPS.

Wait so you do have a plenum or no? IRTBs shouldnt have one but i could be understanding you wrong.

If you do then whats the problem with tunning the regular method? Tune your map then tune the predicted settings for the quick transitions.

I am tuned completely off TPS without any issues. Make sure you have the correct maps selected when tuning. It will look like 1 = unused, 2 = tps. So you will only be tuning Fuel 2 and Ignition 2 maps.
