I got mine all hooked up and was wondering if anyone used a differnt boost pressure sensor with the zt-2 unit? I just couldnt justify spending $100 when I got a mechanical boost gauge to look at. Has any1 used the stock pressure sensor with this? I know its only a 2 BAR sensor and the Zeitronix one is a 3.5 bar, but they both are a 3 wire 5v sensor. I know that the unit doesnt need the boost sensor but Id like to have some reference when I hook it up for data logging. Would it hurt anything to use the stock celica sensor? Or should I eventually move to a gm 3 BAR sensor, or not use one at all?

only the 3.5 bar map will work.

you cant adjust or calibrate any other .

it wouldnt burn out the controller would it? It would just read way off right?

Yup, it'd be rather pointless, but if you just want a blinking light it will do that for you LOL

I have a zeitronix boost sensor I don't need anymore. I"ll sell it to ya for $75 if you're interested.

FYI mechanical gauges are NOTORIOUSLY inaccurate. I've seen them read as much as 4 psi off. Whether you hook up the zeitronix or get another MAP based electronic boost gauge, I would recommend moving away from mechanical either way.

The REAL benefit to the zeitronix system, however, is DATALOGGING. Since you're already datalogging RPM, TPS and AFR, the missing parameter is boost. You can use this to dial in your boost controller, see problems (I found a broken FPR this way) etc. I HIGHLY recommend it unless you move on to a full blown EMS, which I have and no longer need the MAP sensor for the zeitronix
