Hello,
As I waiit for Ken to finish building my 2056 I want to keep moving on other projects. As I mentioned before, I am keeping the LJet, running 2.0 heads, 2.0 intake runners, the flexible couplers from 914Werke, and the larger bus throttle body. I have read a few threads on this conversion/ upgrade and understand it's straightforward, but I may need to verify the AFR. Should I buy a wideband gauge and sensor? Or is this as easy as "adjusting some big wheel one click"? If I should get a wideband setup, which one do you all recommend? Thanks in advance. |

I was thinking that I wouldn't keep the AFR in the car after I got things tuned so I wanted it to be easily removed. I put the main unit and relay on a small plate with two magnets and it just sticks up on the rear wall of the engine compartment. Very strong - hasn't moved.
I do believe i got the extension cable as the length on the sensor is just not quite enough but then you end up with quite a bit of slack to deal with. Wiring: I made a small quick release connector Y to split off power from the AAR lead to relay terminal 86, 85 is ground, 87 is + power out to the AAR and 30 is + power in from the battery (or in my case, i have an aux fuse box that is constant power from the battery) - All easily reversible. At some point, I'll pull that wiring and tidy it up with some better connectors and shrink tube but for now, they have done the job. No viable bluetooth CHT setup that i'm aware of. I have a Dakota Digital gauge with the sensor under #3.  |
