I just got another one and replaced it and now it is working. My ecu had shorted out recently, due to a random loose wire in the harness, but i fixed that and got a replacement ecu and its working fine. The loose wire is probaby from when they took the motor out of the car since i got a motorset. I ...

Does anyone have a diagram of the ecu circuits, i am going to guess that something inside is knocked loose or burned out cause it not to allow a accurate tach signal.

In freqency mode it is going from about 9v and then decreasing with increased rpm, i noticed in the service manual it is supposed to be 1 to 2.4 at 2500rpm. The diagram has the tach signal going to the tach and then splits to go to a v in a circle then to a ground i believe.

My tach output is starts at 5v at idle then it drops while rpms are increased.This isn't related to nistune hardware, but i am hoping that someone might know what might cause this.

I just did a rough calc from the size of the injectors and 1591 is what i got. I will try it, but it probably wasn't a accurate method. I don't know what the proportion of latency to opening time so i couldn't do a calculation that way. I also have hks 264/264 8.5 cams which might be adding some pro...

I haven't changed it from 1520 with the current rom, the injector opening time and closing time is 1.130 0.998. I don't know what the stock times are so i don't really have any idea where to move it, so i haven't messed with it.

The fuel ratio is varying from 13.5 to 18afr. The coolant temp are constant in the 80's. Sometimes when i come to a idle it will be very lean and then sometimes it will be rich and at times very rough idle bouncing up and down. I have adjusted the fuel map to get it to be around 14-15afr. z32 maf in...

I was using the plms usb cable, and kept having problems with .9255, so I wanted to update the plms driver, and the driver from their website was being difficult and then i noticed it was a FTDI driver, so i googled it and found their website, http://www.ftdichip.com/Drivers/VCP.htm Downloaded their...

Has anyone else having problems with nistune locking up vista os. Thanks.
