I have my new AEM 30-0300 installed in the car and have it sending the analogue signal to my HP Tuners software through the EGR port of the ECM since the EGR was removed. Since I was running the AEM 30-4110, I have the following math in HP tuners to convert the signal 5V input to something useable: ([2811.10]/.5) +8.7)
The 30-0300 has different scaling than the 30-4110. The range is only 4v between 8.5 and 18.00 AFR. Can someone help on doing this new math? I've watched Ed's video on this several times but he glazes over this part so fast that I'm not catching it.
Please don't tell me to use Lambda - I'm not there yet!
