Dave Kriedeman Posted November 28, 2015 Report Share Posted November 28, 2015 Hi sanad,I am unfamiliar with your engine.Can you please advise what type of sensors that the Crank and Cam sensors are.How many teeth etc.RegardsDave. Quote Link to comment Share on other sites More sharing options...
sanad maghaireh Posted November 29, 2015 Author Report Share Posted November 29, 2015 Hi Dave yes this engine not too much popular , especially under forced induction . The crankshaft position (CKP) sensor on 2001-2005 1.7L equipped Honda Civic has 3 wires coming out of its harness connector , Each wire is color coded and carries a specific signal . so i dont know if these info enough for you . Thank you Sanad Quote Link to comment Share on other sites More sharing options...
Simon Posted December 1, 2015 Report Share Posted December 1, 2015 We need to know number of teeth on the crank and cam position sensors.Honda in the 90's typically use a 24 and 1 tooth trigger in the distributor.Later motors like the S2000 and K series went to split sensors and multi coil and a very different trigger pattern.

sanad maghaireh Posted December 4, 2015 Author Report Share Posted December 4, 2015 The D17 has a 12+1 crank trigger, and a 4+1 cam trigger Quote Link to comment Share on other sites More sharing options...
Scott Posted December 7, 2015 Report Share Posted December 7, 2015 The only Honda trigger pattern that we have that sounds close to this is the Honda K20 VTC. Quote Link to comment Share on other sites More sharing options...
sanad maghaireh Posted December 7, 2015 Author Report Share Posted December 7, 2015 Thanx csottSo in my case what i must do ? Iam not sure if K20 ckp sensore fit D17 Quote Link to comment Share on other sites More sharing options...
Scott Posted December 8, 2015 Report Share Posted December 8, 2015 You will wire your crank sensor signal up to Trigger 1, and your cam sensor signal to Trigger 2. When you connect the ECU to PCLink to tune it set the Trigger Mode to 'Honda K20 VTC'. Hopefully the patterns are the same and the ECU will then be able to know engine position and speed.

Simon Posted December 8, 2015 Report Share Posted December 8, 2015 If the pattern is the same then there is no need to change the sensors.You just need to wire the Crank trigger signal to trigger 1 and the cam to trigger 2 and then select K20 trigger mode in the trigger menu.If the sensors are reluctor as apposed to the Hall in the K20 then just change the sensor type in the trigger configuration via PC link.

sanad maghaireh Posted December 8, 2015 Author Report Share Posted December 8, 2015 Thanx for a good info. ok .. but i am still using my factory ecu and use the atom as piggyback system ... does this affect ? Quote Link to comment Share on other sites More sharing options...
Simon Posted December 8, 2015 Report Share Posted December 8, 2015 Yes this could have an effect depend on how the factory is using the sensors.In our ECU you will need to have the pullups for the triggers set to off. Quote Link to comment Share on other sites More sharing options...
sanad maghaireh Posted December 9, 2015 Author Report Share Posted December 9, 2015 What if i use an adjustable cam gear like AEM . Does it good solution ?Beacuse my tuner try what you said about wire the Crank trigger signal to trigger 1 and the cam to trigger 2 .. and the engine still not starting . I need your advice please ... my car almost finished Thanx sir Quote Link to comment Share on other sites More sharing options...
Simon Posted December 9, 2015 Report Share Posted December 9, 2015 Changing the cam gear will not effect the position signals.The trigger signals will need to be scoped to see what they are doing.In some cases the way the factory uses the sensor means we are not able to piggy back off them and you need separate sensors for our ECU.

sanad maghaireh Posted December 9, 2015 Author Report Share Posted December 9, 2015 (edited) Ok ... then ? Also the other ecu frome link (storm & extrem ) has the same problem .I said adusitable cam gear beacuse in my case when use Honadata Kpro. Its must change the cam gear .. beacuse the stock cam gear not working with Kpro. As Hondata instruction .

Simon Posted December 10, 2015 Report Share Posted December 10, 2015 The issue with altering the triggers in this case is the need to keep the factory system happy.The triggering on all our ECUs is the same so would expect all to have same issuesHowever the Storm or Xtreme would allow you to scope the signals using the trigger capture function.
