What AFR guage to use
I am looking for a permanent guage to monitor AFR's but I also want to be able to log AFR's with RPM's. What are you using and why. looking at the LC-1 but want some real world advice. Also, not looking to spend $4-700.00.
thanks, Ben

Ben,
I run a LM1 and LMA2 in my 930 at all times, I monitor and log AFRs, Boost, Vac, RPM, System Press, and Control Press. I have a Dyno Tune digital readout on the dash and am very pleased with the system. I bought all of the hardware either on the board or EvilBay. My total cost is just over $300.00 Innovate has been pushing the new LM-2 and the used LM-1's can be found very reasonably and most include the associated cables needed. All the software can be downloaded from their site and the support has been first rate. Cole

I run with an LC-1 and G3 analog gauge, so it's limited to mapping primarily just AFRs. Honestly, I have yet to hook up my laptop to it because of serial cable differences. Overall as an on-board AFR monitor, I'm please with it.

Cole, What sensors are you using to monitor system and control pressures and how did you tap them in to the plumbing. Jim in B'ham |

I use the LC-1 with the XD-16 gauge. The LC-1 ties nicely into nearly any ECU as well. Inexpensive and great quality.

Jim,
Boost and Vac are done with a GM 3 bar MAP it requires a 5vdc power supply which I built with $6.00 of Radio Shack parts then ties into the LMA-2, easily plumed into manifold with vacuum hose. The pressure transducers for control and system pressure are MEAS and I got off Evil Bay used. They are 12vdc in and 5vdc out and again wire directly into the LMA-2. They have 1/8 male fittings on them and are easily plumbed into the fuel lines with a T. After I got them I looked on line www.meas-spec.com and got spec sheets for them. Cole

Innovate LC-1 with a DB gauge. It has been spot on when compared to the data from my dyno runs.
