madkaw Posted January 19, 2011 Share Posted January 19, 2011 I have been doing some reading up on this product and I am considering it for my Z. Though my car is only N/A at the present time, I thought this would be an interesting tool for engine tuning. I have installed a LC-1 and would like to use the LMA-3 in conjunction with it to monitor, or more importantly datalog engine parameters. With the LMA-3 I could include rpms in my datalogging; and if I wanted MAP. I would also like to monitor fuel pressure, but i'm not sure how that will be done. It seems that electric fuel pressure guages are spendy and all I would need is the sensor or transducer to run it through the LMA-3. Anyone done this type of set-up?

ktm Posted January 20, 2011 Share Posted January 20, 2011 I am running an LC-1 and LMA-3. The LMA-3 is great and it has, as you know, universal inputs. It has built in accelerometers (G-tech) that you can use or you use the inputs to log other parameters. I am/have logged (not all at once): methanol pressure, intake air temperature, EGT, knock sensor, AFR, RPM, and MAP. This is an image of my LMA-3 log using Logworks: Quote Link to comment Share on other sites More sharing options...
madkaw Posted January 20, 2011 Author Share Posted January 20, 2011 Bo, It seems like a very useful tool. Have you used to "g-tech" to measure improvements in acceleration? Are you using an inductive clamp for rpms or did you wire the LMA direct to the tach? I'd love to find a way to measure fuel pressure with it. I know it will just take the right sensor.

ktm Posted January 21, 2011 Share Posted January 21, 2011 Steve, Just get a sensor that has a 0-5 volt output and you can calibrate the scale in the LMA-3. I used my Wolf EMS tach signal output. I would imagine that the LMA-3 can be hooked up a positive output from the coil but I am not certain. The Innovate forums as well as Google may help you there. I have used the accelerometers and formulas to back-calculate horsepower and torque for a given run. Quote Link to comment Share on other sites More sharing options...
