Help converting CM flowsensor to AQM with CMGS
Hi all -
I've seen a few others who prefer a turbine based safety running the same setup so I was hoping someone could lend some advice... I'm trying to convert my system (CM flow sensor is shitting the bed causing plenty of boost fluctuations), but I'm no expert with wiring. I had a friend set up the system initially and it's worked like a charm... What is the easiest way to wire the AQM HE505 sensor into the JB4 to still maintain use of the CMGS controller? I've seen plenty of threads with people talking about doing the same for use with Procede, but none for JB4 even though I know a few people are running similar setups. I also DO NOT want to switch to a voltage based safety such as a FSB. I was hoping to reuse the existing wires from my current CM flow sensor so as I didn't have to reroute everything behind trim and through the cabin/firewall. Any input would be greatly appreciated + apologies in advance for not being technically savvy when it comes to wiring... Zach

if you follow my advice and mail howerton engineering you will get the right answer. you need to hook the jb4 directly to the aquamist unit to run map 3. Both Terry and Howerton knows how to set it up.

some info i found in my mail box
The output id .5V in standby, and 4.5V full scale. The flow map with the green wire hooked to 12v will give you the biggest range, about 1500cc at 4.5V. The other two maps have smaller flow rates that hit 4.5V faster. The green wire changes the mapping of the .5 to 4.5v signal coming out of the flow sensor. If you ground the green wire, it will be on the most sensitive map. Leaving the green wire un-connected will enable the middle map. Connecting the green wire to 12v, will enable the highest flow map, which should be about 4.5V for 1500cc.
