it depends on what version of the JB+ you have. If you have the older one with the switch, you can do something similar to our diagram above, except you need to power the switch with a 5V source instead of 12V.
If you cant find a 5V source you can use a 12V, but will need a 3.3V resistor in line. This would allow you to only inject when flowing correctly, if you turn the lower map on ,it will disable the meth but you will see boost. If you want to run meth on both maps just set the cmgs to inject on boost only. CM |

Any effects on our catts btw? Im also thinking of what parts will be touched by the meth, intake pipes/manifold, valves, then the cylinder walls and top of the piston, orings? I assume after that its burnt and then out the exhaust, through our turbos.. |

So I ask you guys again the same: When meth is switched off and I've JB3 normally on map 3 and map 7 is the meth map. How I can be sure that JB3 won't switch to meth map (map 7) when meth is switched off?

Thanks, I detailed that earlier. You can switch based on flow with most of the JBs. If your JB is the older board that has the input for the toggle switch to switch maps the CMGS can switch maps based on flow with that version. The new version will be doing it as well, but using a different output from the CMGS. Since the JB is going to switch maps based on the CMGS reporting back the flow, if the meth is switched off, it cant switch maps. CM |
