So i've been tuning my car lately and ive come into a little complication. I have the stock rsx type s wideband reading and trimming fuel, but i also have my AEM wideband dataloguing my fuel for boost.

I removed resistors c300 and c301 to get the eld voltage readings to read below 1.7v from the AEM.

Now, everything runs fine. But tonight my aem in boost =10.7-11.0 while the rsx one will read 12-13s. Thats quite the difference in between both sensors.

This is all being done on 0 cam angle and up to 4.1 psi to get the fuel curves down.


which to trust?
