I put my P28 ecu with the conversion harness in my 99 dx and the idle is a bit jumpy and when ever i release the gas the car kinda jerks, im pretty sure this is because of the IACv if not what u guys think, and if it is what can be done to fix this. Also i might be crazy but it seems the car is a bit slower is this possible?

 

what motor are you running the p28 on?

 

its a d16y7 for now im building up a y8 project but i wanted to install the ecu so i can wire my gauges to the conversion harness so i dont have to cut up the factory harness

 

So why would you run a sohc vtec ecu on a non-vtec motor? Put the old ecu back in and run it until your done with the y8. Then you can run the p28.

 

its wat i did i just wanted to see how it would run and as i said id like to hook up the gauges i have through the conversion harness

 

try disconnecting the ckp sensor plug near the end of the timing cover, its the wire that goes under the timing cover. it has 3 wires coming out of the plug. mine did the same thing

 

will do!
