I think that I've figured it out. I found this https://forum.autosportlabs.com/viewtopic.php?t=2072&highlight=wideband His gauge has a different range than mine so I adjusted the calibration to match mine. You must enter whole numbers so the controller gauge reads 147 instead of 14.7 but that is...

Ok I found this calibration file and I think I loaded it. viewtopic.php?t=2072&highlight=wideband But My AFR gauge is still reading 0 to 255. I know it's something simple.

Setting ADC values in Aux input options

I'm datalogging with an AEM AFR gauge and the Megajolt configurator. My problem is I want the gauge to read AFR instead of 0 to 255. The AEM instructions tell you how to set it up with their datalogger but it doesn't work with the Megajolt configurator. The scaled value is the only thig that can be ...

I'm datalogging with an AEM AFR gauge now but I'm having trouble getting the aux gauge to read in the units that correspond with AFR. It seems that the ADC value of 0 to 255 is what the gauge is displaying. How can I chance the ADC value? Is it as simple as scaled value times voltage equals ADC? The...

It seems that the really smart people on here are busy with something else. I am not a really smart person but I stumbled on the answer to your question by chance. find the ports in the settings of your computer. With the megajolt hooked up with the correct cable I tried each one until I figured out...

Correct me if I'm wrong. A narrow band O2 sensor puts out 0 to 5 volts. If I send that 0 to 5V output to the Aux input of the MJLJ then the Aux input gauge of the controller could be configured to read the AFR. A narrow band o2 sensor would be cheap and easy for me to install in my Spitfire. I'd lik...

So if the output of an o2 sensor at 14.7AFR is .5 volts. And I set the scaled value on the input channel options as 14.7 as .5 volts it will show up on the data logger? I would fill in the AFR values for the corresponding voltage values to complete the picture. Sorry but I'm old and barely know the ...

Dataloging software for Megajolt and O2 sensor

I'm very happy with the MJLJ, but now I'm looking to tune my Weber DCOE's along with the spark to maximum power and fuel efficiency. Before I go and buy an o2 sensor and gauge is there any software that will datalog the spark and AFR side by side? My low tech alternative would be to have my daughter...

I suppose that sitting in the barn does nothing to simulate on the road conditions. I can't wait for the snow to melt so I can start playing with my map

Setting load bins with dual webers

My Engine Spitfire 1500 ported and polished head 4-2-1 header and dual DCOE 40 carbs. equal length 3/16" vacuum lines going to a 70cc reservoir then 1/8" line going to Megajolt. My Question I just got my car running on the megajolt and now it is time to tune it. My engine will not go down ...
