Gregconboy158 Posted July 1, 2021 Report Share Posted July 1, 2021 As title, I've blown the honda b18 motor again so I'm done with them. Looking to put a later k20 engine in now. I've currently got a PnP civic link 95, can I use this ok on the k20? Obviously I know ill need to suit the k20 loom to obd1 ecu plugs but other than that all ok?

aerace_fab Posted July 2, 2021 Report Share Posted July 2, 2021 There was a post on here recently of someone stating they've got one working. Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 2, 2021 Report Share Posted July 2, 2021 Yeah should be doable, you will have to shuffle a few wires around. Exhast cam sensor to trig 2, inlet cam sensor will need to go to one of the DI's 1-4. Vtec solenoid wired direct to pin A4 (has high side drive hardfware on bottom board so doesnt need relay as shown below). VVT solenoid will have to go to Aux 1-4.

Gregconboy158 Posted July 3, 2021 Author Report Share Posted July 3, 2021 Thanks Adam just what I was looking for! I'm sure ill be back for some help once I get round to doing the loom! Quote Link to comment Share on other sites More sharing options...
Gregconboy158 Posted August 12, 2021 Author Report Share Posted August 12, 2021 Just bumping this, in process of repinning a k20 loom into obd1 plugs to suit my ecu currently (quickest way for me to get back on circuit atm) I'm a bit stuck on how to wire the crank/cam sensors where the b series has dizzy. I've attached the pinout for obd1 ecu, on the b plug it says about P side and M side, what does this mean and how do I wire it? I think everything else i have sussed Quote Link to comment Share on other sites More sharing options...
ClintBHP Posted August 12, 2021 Report Share Posted August 12, 2021 You need CKP (24 teeth) as Crank and CYP (1 tooth) for CAM. Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 12, 2021 Report Share Posted August 12, 2021 Info from help file below, Crank signal to B16, exhaust cam signal to B12. Trigger grounds to B15 & B11. Quote Link to comment Share on other sites More sharing options...
Gregconboy158 Posted August 14, 2021 Author Report Share Posted August 14, 2021 Thanks for reply Adam, on k20 loom it seems the crank and cam grounds go to logic ground, will this be ok or shall I cut and splice them to the b11 and b15 pins?

Adamw Posted August 14, 2021 Report Share Posted August 14, 2021 What pin are you calling "logic ground"? Quote Link to comment Share on other sites More sharing options...
Gregconboy158 Posted August 15, 2021 Author Report Share Posted August 15, 2021 On the picture I put above its A26 and B2. On the k20 loom its A8 and A9 (2005-2006) pinout Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 15, 2021 Report Share Posted August 15, 2021 That will be ok. Quote Link to comment Share on other sites More sharing options...
Gregconboy158 Posted August 16, 2021 Author Report Share Posted August 16, 2021 So can leave b11 and b15 blank? Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 16, 2021 Report Share Posted August 16, 2021 yes Quote Link to comment Share on other sites More sharing options...
Gregconboy158 Posted November 5, 2021 Author Report Share Posted November 5, 2021 Just bumping this, is the vtec supposed to be high driver type or low do you know? My b series was low i've checked on my b series map and i've got 2 calibrations for k series and 1 is listed as low side and the other high side Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 6, 2021 Report Share Posted November 6, 2021 What specific ECU and aux do you want to use? The civic plug-ins have special drivers on the circuit board for the B series VTEC that requires high side (only 1 wire). Quote Link to comment Share on other sites More sharing options...
