Well, it was a nice thing while it lasted. :'(

I think you're still safe though. Rice boys usually get sniffed out & exiled from this sight rather quickly. Well, most do. You're still here >:D

400 of the boards you saw pictured in xenocron's post above will be here in the first week of march, depending on shipping times. Final pricing has not been finalized on kits, but bare boards (i.e. you supply the MAP sensor, wiring/connector, optional 0603 capacitors, recomended waterproof epoxy, etc.) should be around $10 including domestic US shipping.

Chris or I will keep everyone updated as we finalize details. ;D

Sorry Rene, I've been away this past week.


It's not free-floating. The inside is filled up with plastic epoxy.

BUMPP. i got the 4bar MPXH6300AC6U ( 3 bar positive). i wanted to know what values would have to set in crome to make this sensor work properly?

@hiprofile: why is it 200-3040 for a 3bar?

you guys need to learn how to read datasheets and do math. RTFM FTW!!!

Won't the data sheet tell you the voltage slope ?
