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?

Awesome!
So use 1.2 but ALSO make sure to check the battery voltage correction by disconnecting the oval plug on the alternator as I described.
Its super critical to do this before trying to tune the VE table because if those settings are not correct, you will have all kinds of fueling issues when humidity or temperature changes.

So I went through and tried to tune my idle to 14.5 - 14.7 AFR and the car kept on dying out. It would hunt around the fuel and ignition table for a while before finally just sputtering out. I did some research and found when the idle isn't steady it is most likely an ignition timing issue. I went to a fixed timing of 10 degrees BTDC the car idled better but still was giving me trouble so I started adding fuel until the the idle was strong and that was at 13.2 AFR. The timing table you had set up for me had the cells for idle set to 19 BTDC. I remember when I took some logs of the car when I had the AEM piggyback and stock ECU kept the timing at 8-10 BTDC at idle. Also, I remember reading somewhere that the 5sfe likes to run a little rich especially at idle. I used the Megasquirt timing table estimator along with you table and created a hybrid of the two that would give me a good idle but some good timing for boost as well. Problem solved. I then worked on the voltage correction and got the EGO correction gauge to stay at 100%. Tomorrow I will ensure that timing does not float when I am on the throttle and then start auto tuning the rest of the fuel table.
