My note book does not have DB25 printer port, so I brought a USB to DB25 cable, compatiable with USB 2.0 and 1.1, using 2305 chipset (seller describtion), when plug in the cable, I can see USB printing support (IEEE1284 controller), but after connect to Nistune Base Image Programmer Board, I see a w...

I suggest to pull "0" across the whole Min TPluse width table when adjusting the Injection Latency ( and Injection Multiplier). When the number in the Injection Latency table is too big, it usually show rich A/F reading on idle, but finally you have to put some reasonable number back in th...

Want to know more about "Increase Fuel" in Type 1 board CA18DET, There are 8 column in the "Increase Fuel" Usually I see zero on the most left column, and it goes higher number on the right hand side. If fast throttle movement travel at 20% throttle open, the enrichment would ref...

Under what condition this two limit table affceting the injector behaviour ?

Nice mod !!!!
Is it only for S13 SR20DET Type 3 board ?

Your ECU might be in limp mode. Is there any blinking red light on ECU ? If your ECU running in normal mode, if your enigne and ECU harness connected properly. And when you turn off the key, you will hear the relay inside the ecu cut off the power delay in 2-3 seconds. (you will hear the sound "...

The problem might be on the solder of 28 pin socket,
even if the solder looks good on the back side of the ECU,
it might not perfect flow to the surface side.

Just try it, use the solder iron to melt the 28 pin solder again.
On each pin, let the solder iron stay on the solder for 2 seconds.

I have check from a CA18DET 4 wire AFM, the extra pin is a variable resistance around 1Kohm, but it seems ok without connecting.

I have just test it on today, the board works fine

I just make it , but no car to test it !

Yes, I know that that wire is for emisssion control (somewthing like idle mixture),
I have been reading a post in old ECU froum, if chaging AFM, this wire must have a resistor connected,
to control the voltage as a sihgnal to ECU, but I have no idel what ohm of resistor to use.

I'm going to help my friend to tuen his S13,
but I have found that the CA18 AFM harness have 4 wires,
except +12V, signal, GND, there is one more green wire with yellow strip.
what to do for the extra wire ?
I use RB20 AFM and left that extra wire unconnected now.

As title,
I need a rom file for CA18DET with RB20DET AFM and 444cc GTR injectors.
If someone has a tune and don't mind to share, please e-mail me louiswun @ hotmail . com
Thank you very much !

I'm having problems trying to get a type 1 rev 3b board working in an A31 rb20det. The ECU works fine with an OEM eprom installed however when installing the nistune board we can't connect via the USB consult. The car still runs OK, it's just a matter of being unable to connect to the ECU. The ECU ...

When the throttle closed, you should see the "Idle" showing in RED, If the Idle is not switched on (Red), the idle timing will goes up to 30, and due to the advanced timing, the idle will stay high like yours, just adjust your TPS until you see the Idle switch is On (Red), and aim at 0.45V...
