Anyone pegging their 3 bar map sensor?

[Dave King]

Anyone know of any 4 bar map sensors that work well? For the guys that are pegging 3 bar sensors and still using them are you just going high on the top column on the VE table?

Not sure how much you're "overrunning" the 3 bar sensor, but if you're only just going beyond what the sensor can handle, it might be better to stick with it and adjust the cells at the edge of the table to accommodate your fueling/timing needs. Remember that FAST will choose the "closest" cells, even when you're running outside of the table. Usually, going with a bigger MAP sensor, the resolution of the rest of the table suffers in order to accomodate the bigger sensor range... as for a 4 BAR map sensor, I do remember someone mentioning such a thing before...try a search!

You can run a Kalvico 5 bar map sensor. You will need upgraded software from FAST. Call them up. Also can you find out if they can get a 3.5 or 4 bar map sensor working with FAST. I know Kalvico makes a true 3.5 and 4 bar map sensors. With a 5 bar you really stretch your tuning resolution. But it still works pretty well.

The 4 bar sensors aren't really any different than 5 bar sensors. The difference that we have seen is that the 4 bar sensor has an operating range of 0.5 to 4.5 volts, rather than 0 to 5 volts.
