hey all i am up on a project *Connecting megasquirt ms3x v3 mainboard on a usdm d16z6* i have done the wiring the car starts fine on stock p28 ecu but it wont start on the megasquirt the problem is with the megasquirt there is no spark whatsoever this is my first try on a standalone ecu! i am uploading pictures (the wiring connections and the Basemap setting plz guide me through)
thank you all i need to do this ASAP Pictures are as follows!

 

i have done the wiring as per above picture^^^^

 

i'll share a write up i found for OBD0 conversion, which you can use to help yourself with the wiring. what i have found when i attempted this, is that you need to play with the VR conditioning resistors for it to properly see the VR signal from the distributor, both the R52 and the R56 variable resistors. here is an article that can help.
good luck.

 

Hopefully you built the right circuit for the VR signal and did you use a jim stim to test it to see if it actually works?

 

Jim stim?? circuit for the VR signal? all i did is connected the wiring made a harness for the v3 mainboard i didnt open the megasquirt what circuit you talking about? thanks

 

ok ill check the wiring! but i didnt get the VR conditioning thing where should i look for the vr conditioning? in the software? and can u share some details on how you connected your megasquirt to honda? the settings and all? thanx

 

Where did you get your MS? The pots I mentioned are inside the unit. You will need to open it. I cannot share the settings with you since I have abandoned the idea of using it on my car for now. But read the file I had shared. There is a lot of info there. You can also go here for some info.

 

Another one of those "I bought the damn thing and expect it to work" thread....
At this point I suggest you abandon the project and get a chipped ECU with datalogging or a s300. Less headaches involved.

 

i expected it to work because i have paid 700$ anyways i thought it was plug and play i didnt expected such a reply on honda-tech anyways thanx for everything ill find my way out cheeers

 

Have you looked at the links I gave you? Megasquirt is NOT a plug and play system.

 

You need to set up the VR circuit on the circuit board for a magnetic VR sensor. These things are far from plug and play.

Did you put this together yourself or buy it assembled?

What version board do you have V3.0 or V3.57? They require different procedures.

All of the documentation is available on the DIYautotune.com forum.

Here is the VR setup page; http://www.msextra.com/doc/ms3/ignit...ml#vrv357logic

These document pages are now your Bible..... if you decide to stick with the MSIII EMS.

 

i have read every single line on the diyauto tune before making a thread but i guess i have read the wrong part! i am using ms3x357 looks like 3.57 and i have done the wiring according to 3.0 let me overview everything again ill come back to you with step by step details what i have done! thnx

 

i am using TDC sensor i have ignored the cyp and cam sensor

 

the settings are as follows

 

i turned the pot aswell! nothing happend! still no spark and no pulse to the injector!
