I know that this is a noob question but I am going to ask it anyway. We just finished doing a B18C ITR Spec 97 drop into a 92 Integra and I want to get the data logging working. I built the Max232 convertor board and installed it into a P61 ECU. I also cut the J12 as is required in all the literature I have read. The external ROM has the Data logging feature added but no data is coming out. I have checked all the connections and they are fine and correct. I am connecting to a laptop on COM1 using a regular serial cable but no data is coming through. Is there something different about a P61 ECU? Is it that only the USB to RS-232 convertor cable will work in this application or can a straight RS-232 to RS-232 cable from the laptop to the ECU will function also?
Thanks
