Q:

Does it have two outputs? I'd like two independently control the left and right side AFR's

Asked by MARK on November 22, 2017

A:

Thanks for your question. As members of the community have indicated, the DLG-1 allows you to simultaneously monitor and display measured data from the two included O2 sensors on the gauge face. Additionally, two 0-5V analog signal outputs are provided in order to feed sensor data to external 3rd party electronics such as data loggers or engine management systems. If you have further questions about this product as they relate to your specific application, please reach out to your Summit sales rep or call our tech team toll free at 800-348-3037 and we would be happy to offer further assistance to ensure proper product selection for your application.

Q:

Would this be compatible with only open headers? I have +\- 16” collectors

Asked by JASON on December 25, 2018

A:

Thanks for your question. As a member of the community has indicated, exhaust piping length following your sensor mounting is unlikely to be sufficient to provide good readings at idle and part throttle due to reversion pulses and fresh air contamination of the sensor. However, readings at full throttle would be usable as the volume and velocity of spent exhaust gasses passing the sensor will be sufficient to overcome the piping length concern. For greater reading versatility consider increasing the piping length following the collector to 24" or so which will help reduce the contamination described above during part throttle conditions. If you have additional questions about this product or installation as it relates to your application, please contact your Summit sales rep at 800-230-3030 or contact our tech team at 800-348-3037 and we would be happy to assist you further.

Seems very well put together

Summit RacingSummit Racing Verified Purchase

INN-3891
i only had one slot open on my gauge pod but needed two widebands one for each cylinder bank. this product is definitely expensive but arrived fast and is very well put together. with the interchangeable face plate it fits in and looks just like the rest of my silver ringed white faced gauges. the only thing I don't understand is the gauge has one input for one O2 sensor and then it has to piggy back with an external module for the other O2 sensor. This just makes wire routing even more of a nightmare. overall very nice product and would recommend to someone that didn't have room for two more gauges. ...read more

Seems to be a good high quality gauge, and is pretty straightforward to hook up. I didn't use it yet so can't report on that. Josh

DLG-1 / LM-1

Summit RacingSummit Racing Verified Purchase

INN-3891
Great gauge .Especially for tuning dual quads.Was a bit messy in the wiring .I think innovate could do better with daisy chaining the power wires between the DLG-1 to the Lm-1..An extra couple of wires and a 6 pin plug would make no difference in the installation.except easier. The O2 sensors are questionable as I have had one fail after 15hours of use ...read more
