VtrSp1 Posted June 20, 2021 Report Share Posted June 20, 2021 @Adamw i'm ready to install a HC92X Plugin for Honda Civic 92-95 with COP , Oem distributor in a turbocharged car I can Run the COP with the oem distributor in sequential injection and direct spark? I can use a Knock Sensor? I don't find information about that. Quote Link to comment Share on other sites More sharing options...
aerace_fab Posted June 20, 2021 Report Share Posted June 20, 2021 yes for the direct spark using your distributor for triggers. and per the manual it says 2x knock inputs, I don't see the wiring pinout included if that's what your question is.

Adamw Posted June 20, 2021 Report Share Posted June 20, 2021 There is no knock input on the 92-95 civic ECU. Quote Link to comment Share on other sites More sharing options...
VtrSp1 Posted June 20, 2021 Author Report Share Posted June 20, 2021 is there no way to get it? Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 20, 2021 Report Share Posted June 20, 2021 As far as I known the OBD1 honda's didnot have a knock sensor so there is no knock pin on the factory header. If you returned the ECU to NZ we could add a flying lead to the adapter board to make the knock pin available. Quote Link to comment Share on other sites More sharing options...
aerace_fab Posted June 21, 2021 Report Share Posted June 21, 2021 traditionally pin D3 would be factory knock sensor for most p30 and p72 obd1 ecu's. Quote Link to comment Share on other sites More sharing options...

I can do this modify with flying lead to the adapter board for make the knock pin available? I'm on Italy and it's very expensive to me send the ecu to NZ Quote Link to comment Share on other sites More sharing options...
VtrSp1 Posted June 23, 2021 Author Report Share Posted June 23, 2021 @Adamw i have do a trigger scope ,the car start and run great! I have do the timing light check for the trigger offset and next i have do the test to 1cyl with -20° for see if the ignition is retarded with the timing light on 1st cyl with great result! Can you look at the scope and trigger threshold if is ok?

Adamw Posted June 24, 2021 Report Share Posted June 24, 2021 Yeah, that all looks fine to me. I will PM you some info about the knock sensor connection when I get time to do a quick drawing. Remind me if you havent heard anything in a couple of days Quote Link to comment Share on other sites More sharing options...
VtrSp1 Posted June 26, 2021 Author Report Share Posted June 26, 2021 @Adamw do you have time to send me the drawing for the knock sensor modify? ☺️ Quote Link to comment Share on other sites More sharing options...
VtrSp1 Posted July 13, 2021 Author Report Share Posted July 13, 2021 @Adamw Finally i do the tune on the dyno but i have a few issue.. The first is some noise on engine speed , i check the trigger value for trigger 1 and 2 , it's like as the suggested on help manual. Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 13, 2021 Report Share Posted July 13, 2021 The RPM noise looks pretty normal for a distributor trigger. Quote Link to comment Share on other sites More sharing options...
VtrSp1 Posted July 22, 2021 Author Report Share Posted July 22, 2021 @Adamw ok thanks a lot.. I do a first track test and the accell pump don't work.. I have the log in the race but it's too big 60 Mb Looking at the log on the dyno, there is the same issue, i attack the dyno log I attack the calibration , do you have any advice about the accell pump not working?

Adamw Posted July 22, 2021 Report Share Posted July 22, 2021 Cold correction is a multiplier so multiplying by zero at 80/90deg means you will have no accel fuel when warm. It is normal to have values of 1.0 at normal temperature and in modelled mode you usually dont need much extra when cold. My car has 1.0 right across. Also I suggest you enable Async injection like below, this reduces the need for accel fuel a lot. Quote Link to comment Share on other sites More sharing options...
