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?

After messing with the DIYPNP for the 4th gen 3sgte I found it was going to be a downgrade using it. Since the motor is sequential injection and COP ignition, I was using all my outputs just to work those basic features. I was going to lose all my idle up capabilities and would not have anything left for any expansion down the road. The DIYPNP is great for a batch injection and distributor setup of the 5s but as the motor becomes more complex the ECU loses the ability for the extra fun stuff.

After talking with the people at DIYAUTOTUNE, I decided to pull the trigger on a MS3pro EVO. This will give me all the basic functions I need plus the ability to add extra sensors, performance mods, and safety features. I plan to start with their base 3sgte tune and go from there. The final goal will be to get it running well with the Auto Tuning features. That should yield me a safe tune. Then I will take it to a tuner to get the fine ignition timing tuning done. The great thing is since I will be building this as a plug and play unit I will have the ability to go back to the stock ECU if I want to move the ms3 to another vehicle.

My car put down 238 horsepower and 233 torque on the dyno at 15 psi. That is with aftermarket camshafts and a stock ECU. With my stage 1 BC camshafts and a good tune I am going to shoot for 280 horsepower.

I will be starting a new thread to document this work because this is no longer dealing with the DIYPNP ECU.
