Fast Ecu (map / Tps)

[camcojb]

I believe when you go sequential, you lose fan control. If its not seguential your fine. You def. need tps sensor but if you run aplha n mode you dont need map sensor. But don't run alpha n mode. If you are running less than 15 lbs of boost stick with a 2-bar sensor. jim

That was it, sequential loses fan control. I knew it was something I hadn't done so it was a non-issue for me.



Yeah, don't run Alpha-N!

The FAST unit most definately supports both TPS and a MAP, and you need both!

You also need the TPS for Acceleration Enrichment parameters; namely, AE vs. TPS rate and AE % vs. TPS position. both are important to have.

The TPS sensor is also required for the ECU to enable IAC and timing trim functions during idle; when the TPS falls below whatever value you set for your idle, the ECU will start actively using the IAC and timing trim to maintain the idle speed.

As far as FAST options, I know you lose the fan control ability with sequential and/or with the 2-stage nitrous option. Another option (I can't recall which) means you lose fuel pump control. Yet another option I can't recall means you lose IAC functionality.
