i have the b18 obd2 motor to my dropped into my ek. i have used the dx ek ewh for swapped. i have done the iacv two wires mod and repin a14 to a12. i used the obd2a to obd1 jumper harness that i have bought from xenocron.com. i used obd1 P75 i plugged in everything then i start the ek, it is running but it is running very rough at idle. it also dies out by itself. put on the road test drive it, it was bogging. then i switch the p06 ecu it the same thing happen, then i borrowed one of my friend jumper harness swithed it in. it still does same thing. no code at all

Then i put back the obd2 ecu of the dx. it is running fine. even cel is on with secondary o2 code.

please help

thank you

 

adjust the idle on the throttle body it should be a flat head and adjust that to the left till ur idle stays up.usually when ur car starts up and dies it's the intake air temperature but correct me if i'm wrong.

 

The p2e uses the iat on the filter box right on top of the throttle body
The p75 uses it in one of the runners on the im you can keep either style you want just wir it respectively

 

i have adjusted the iacv still rough, i mean the vehicle running rough sound like misfire also bogging act like fuel cut when test drive. iat is not really important with bogging and fuel cut.
i've seen lot of ppl got the same problem on this site. but they never have the answer post.
i've switch the distributor to obd1 and runs with obd1 ecu. the same thing happen
i've check with boomslang distributor conversion, it shown different, it shown backward of cyp and tdc mean neg switch to pos, is it that rite?
thank you

 

Maybe your timing is off by a tooth?
It would bog and maybe die if its off by more than a tooth

The dizzy conversion shouldnt be it. They do this for a living; and I did it in like 10 min from start to finish its pretty much color matching

But check timing it wouldnt hurt

 

how do you adjust your iacv?is it possible?but if fuel cut it could be the tps in the wrong position.

 

i had the same problem and the same exact setup. it was the timing. it was retarded way too much. also, check spark plug, injectors, and spark plug wires. is it in the right order?

distributor: 3 4
1 2

head: dizzy to timing belt - 4 3 2 1

also check if the plugs are correct. iacv, tps, etc...

 

I HAVE REPLACE ALL SENSOR I GOT TODAY, TIMING? IT IS RIGHT TIMING ON THE INDEX MARK, I HAVE CHECK THE FIRING ORDER WITH MANUAL IT SHOWN 1342 ON THE DISTRIBUTOR SIDE
NOT 3412 AS U DESCRIP
THIS EK FRUSTRATING

 

dear fastrxu
i have check the timing. it right on index mark. i just took out the obd1 ecu and put back the p2p ecu, it is idle fine. swap to obd1 it is idle suck. dont you think the obd2 distributor cause this. do i have to swith it to obd1 distributor?
thank you all

 

1998 dx hb with b18b1 swapped

i have been swap around, ecu and ewh. i noticed that, if i install obd1 ecu it cause misfire, it souds like off timing, but if i install stock ecu back in it idles very smooth but it has hesitate (dead point at 1500 rpm). any idea?

 

bump did u ever get this fixed got same issue
