Building a diypnp, Standalone harness wiring Options

[HardHead93]

I have been having nothing but trouble with my AEM FIC on my 5sfte set up. I have a 97 Celica GT Convertible with a newly rebuilt engine and a 16G CT-26 turbo set up. The ECU is not working well with the signals the piggyback is feeding the stock ECU. Based on a couple of posts I have seen on 6gc.net, I broke down and bought a diypnp 76 pin standalone. The diypnp has all the features I am looking for and the price doesn't break the bank. I just finished soldering the main board and am about to start doing the harness jumpers. Can anyone provide and example for wiring the diypnp?

Keep the same afr target table. The car should idle just fine at 14.7 AFR. Here are a few things to try to fix this.

1. turn off ego correction. Sometimes if the values in the PID section are not correct, it will cause oscillation. Turn it off to see if its causing the problem.
2. turn off closed loop idle. The PID values might be wrong, or you need to set up the initial idle values table to work better with your setup.
3. The timing table might be at 19 degrees, but the actual value the car idles at comes from Idle Adaptive Advance. Try changing that graph to a single value like 15 degrees.

You were right! I turned off EGO correction, set to open loop (warm up) idle, and changed the Idle Adaptive Advance table. The Idle Adaptive Advance table was set to 20 degrees, no wonder I was having problems. I played with it and the fuel table. Now the idle is steady at 12-13 degrees (checked with a timing light) with an AFR between 14.5 and 14.7. I also re-entered the 3sgte table you gave me with the timing taken out up top.
