My recent H22a swap into my 93 Lude is having simular issues. I bounce back at about 4k tho. Plus there's a slight bogging type of issue. It just doesn't feel responsive. I read about from the person who started this post that the crank angle sensor is not on the jdm motor. Were they refering to the crank shaft positioning sensor (CSPS)? B/c I am throwing a code for that and for the temp sensor. There is no temp sensor on my JDM block. I have only seen that on my USDM H23a1 and my H22a1 (if thats the one that the green plug connects into in front of the block just under the dizzy). When I recieved this motor I did a basic tune up NGK plugs & wires, new Dizzy, rotor trans flush, oil flush, water pump, and I was going to change the belt but it was in excellent shape so I never did that. I checked the timing and it's TDC. So everything on the belt side seems to be in order. I went over the MSD ignition system and coil wiring and that seems fine. Also I took off the internal JDM dizzy for the External USDM one that I had on my other motor. So I am using that. The only thing I can see that I don't have hooked up is the Knock sensor, but thats b/c I didn't worry about replacing the broken sensor since I am running a p28. Now I'm sure I will get flammed for this but the p28 is stock. I didn't have it chipped. The mods I currently have on this motor are below. Incase this gives anyone a better ideal of what might be causing this. Thanks
