upgrade. I have revised the design and it will contain 4 different programs in it rather than the three I originally stated. This is to accomodate for NOS setups. Basically the way it will work is a wire will be connected to the TPS sensor lead (at the ECU) and connected to one terminal on the multi-map device. There will be another switch you can mount anywhere within 6' that will have three positions. One will be for valet, one for pump gas, the third selection for a NOS map setup and fourth for race fuel. A pressure switch will be necessary for spool-up action only where the TPS lead will go through and you can set the pressure switch to whatever boost pressure you want it to stop the spool-up burst.
The scalability of the device will handle any of these kinds of configurations and most likely any other involved setup someone may conjure up.
