S300 sensors jumping

Post by cardinal811 »

I dont think it's the soldering of the joints is my issue. I put the OE P13 in and the car does the same stuff. I checked the fuel injectors by turning over the car with the rail and injectors pointing into the air and they dont stay on. I have not done a valve adjustment cause I want to heat up the motor 3 cycles and then retorque the ARP head bolt like they say to do. I think its shooting fuel to a particular cylinder while the valve is closed. Like the dizzy is out 180*, but I can only put the dizzy on one way. I also check for ground on the injectors by unplugging the A plug on the ECU and try to start the car= no fuel so its not the wiring to the ecu, its a HASport harness. You have any ideas

FINAL UPDATE..

Turns out, my p72 developed a chronic failure problem that popped up when ever it wanted to, thus throwing a solid CEL and not allowing the engine to start or run.. Some critical component on the board most likely became damaged from the heat of de-soldering/soldering the board.. Nothing looked burned or out of the ordinary, but I just had it w/ the uncertainty and reliablity of the ECU so I just junked it and have since pulled components parts off of the board to retrofit a backup p06 to run like a p72..

So far so good w/ retrofiting the backup ECU for the s300 and converting it to vtec, its working fine and I will be adding the knock board to it this weekend.. It threw a code for the knock sensor, but i disabled it in smanager..

I was just about to give up on this too..

Hi, I have quite same problem http://hondata.net/forum/viewtopic.php?t=5835
but I can't even start my engine. One guy syggest to send it to hondata but I live damn far from them. As You can see in my post I tried in another ECU and there is still not right. Should I re-solder all socketing places??

Thanks.
