I have done the following fix, but still not have yet stopped the RESET.

I have install helped a friend to install an MS parrallel, please see log and map.

I have done the following:
- Clean ground, both ECU ground and terminal.
- Seperated ECU ground and AEM WB ground.
- Added Additional Ground to 2A or 2C from fuel rail ground.
- Gapped spark plug to .025

Well, none of the aboved worked.

Any comments, please free feel to share. I am out of ideas.

 

I've been through this, too. Recheck all of your connections on your parallel harness and you might add a few more grounds.

My friends PNP we ended up adding 9 new grounds all across the car, even grounded the ECU case to the chassis brace under the car. I know its very frustrating but just keep at it, I think it might be a power / grounding issue for the resets.

 

added in total 3 more ground from fuel rail. 2A, 2C, 2B pins. It seem to hold up without reset. But much I get ahead of myself fixing that problem, another came when I adjust the timing.

Timing mark was all the way at the 10am area, then i swapped the Stock ECU back in, the mark is still in the same position.

Sigh...

 

Well.. good thing dosen't last very long. No reset at idle, but when I tested out on the street with part thottle RESET is back!!!!

What are causing this? only on part thottle around 20%

 

May be way off, but you may need a capacitor on the coils to reduce noise. Type in capacitor in the search function and research it. It may be the problem. There is an utter lack of help in the MS forums on this site lately. Half the new threads are in BS and nobody helps all the newbs with their MS's. I'm MS2E, so I don't know MS1 all that well. But I'll try to help. Posting more info on your setup helps too. Like tell us everything that's stock and everything you changed. EG-injector size, low/high ohm, coils, grounding, wiring mods, any other mods, etc.

 

it has it. I built the MS in question. First one that I've had any reseting issues...I suggested the grounds.

 

Brainack has been a great help to nail the problem. I have solved all the reseting issues by taking out the Splitfire COPs. Runs great now.. no more reset driving all day.


Thanks all for your inputs, Thanks Scott.

 

that's very interesting....

 

wrong impedance maybe? do you have them set up individually or wasted spark?

 

how do they install? I'm curious.

 

Does not attached to the ignitor like our DIY COPS, it plugs to the Coil plug then goes to a small capacitor modedule and to some Nissan coils.
