O2 Sensor Heater Codes with Meth Injection
I recently installed an HFS-6 system on my Porsche 996TT. I am running a 75/25 meth to water ratio.
I have been getting an odd code coming up only when I am running my Aquamist system whereby the front 02 sensor heaters seem to be throwing these codes. I am running a catless 3" exhaust. P0155 Oxygen Sensor Heater ahead of cat bank 2 P0135 Oxygen Sensor Heater ahead of cat bank 1 When I switch back to my pump file with no meth injection the codes do not come back so obviously the sensors are fine! I am wondering if the meth injection is fooling the DME into thinking there is a problem with the 02 sensors because of the unexpected low temperature readings at the sensors when the meth is being sprayed. Any thoughts please. Cheers, Ben |

Re: O2 Sensor Heater Codes with Meth Injection
This is interesting.
How much 75/25 are you injecting? Or if you know the water jet size. I was wonder if you have set the system to cut in too early? Richard

Re: O2 Sensor Heater Codes with Meth Injection
Hello Richard,
Well I did some more data logging tonight and found out that if I run on my pump map which is 94 octane and have the meth engaged the codes no not come up! I am running two .90 jets with the following settings: Thres Adj at 11:00 am IDC Trim at 8:30 am or fully CCW IDC Gain at 11 am Ben |
