Is there a way to increase fuel using a switch input? Car has an electric exhaust cutout and we noticed the A/F goes a little lean when it is opened.

I see a base map for a B16 turbo with 240 injectors. I have 440’s, so I was thinking I could just change the injector size in the calibration, but now I am trying to figure out how it was possible to use the 240’s. If the fuel pressure was increased or other changes were made to get more fuel, this ...

I got it to work with a 50 ohm resistor, so that is only about 4 watts of heat (use a minimum of a 10W resistor). I found sources that suggested using between 20 and 40 ohms.
I left the 1K solidered to the O2 connector and added the 50 with connectors so I can remove it when I install the OBD1 ...

I installed my PLX wideband A/F and using the NB to my stock P30 OBD2a ecu. Works good but I cannot eliminate the heated fault code with a 1K resistor or 250 ohm. A 10 ohm will do it, but I do not want that hot resistor under my hood. Do the OBD2 ecu’s need to draw more current to trick this circuit ...

I am just try to satisfy my curiosity and spend hours searching the net and still don’t know. What I think I read and I am not sure this is accurate:
They both will fit if you use the Honda style SL4’s.
They have different bodies and slightly different lengths.
They have different spray patterns
I ...

I want to install a S300 in my 97 DelSol VTEC and retain the knock sensor. The current ECU is a P30 OBD2a, so I will need to purchase a used ECU. There are several OBD1 ECU that have the knock circuitry, is the P30 OBD1 the best match for my application? I see Hondata will test the ECU. Will a stock ...

How important is the knock sensor? Have people been able to retain it with the S300?
