rpm or vacum to voltage

Post by Vpgts076 »

Hi guys,


I am looking at supercharging a Holden 304 and am looking into water injection however kits are way too expensive ... Rather Thanks running a Hobbs switch and set to x PSI and have the same water flow from x PSI to limiter I was wondering if there was a cheap way of say adjust voltage to PSI or rpm to stage water injection..

Tha ks

If you are using 12P then one of the flex outputs can be setup to do that. Can be mapped against anything, for water injection MAP vs Charge temp or MAP vs RPM might be a good way to set it up.

There is info on setting up the flex tables here .. http://pcmhacking.net/forums/viewtopic.php?f=28&t=3051

Hi mate ,

Currently running kalmaker n/a tune as supercharger isn't installed.

Who is the best person in Melbourne for $12p tune?

For reference, if you've got an eprom writer that supports the nvram you can put 12p on the kal hardware and use that.
