MS3 pro EZ30 Subaru swap sync loss

[kamotors]

Hi, decided to join the forum since I'm having quite a few issues.

I purchased a 2001 2.5rs with an Ez30 swap. The car was a running car but he p.o. stripped it out to build a "race car" and then ran out of funds and had to sell. SO I bought the car looked it over and decided it would be easy enough to get on the road again.
Car has Ms3 pro all wired in by previous owner, I've looked over his work and its decent and I redid what I felt was necessary. I added a ECU relay, wired in the fuel pump, electric fans/lights etc.

I was originally having trouble getting the ECU to register on my laptop, ended up sending it away for repairs as it had a bad diode that was popping the internal fuse.
I received the ECU back yesterday and it connects up perfect now. Its on an experimental firmware for some reason (i'm guessing due to VVT/VVL).


My problem now is that I cant get the car to start and its losing sync as it cranks over.( clicks the fuel pump relay when it loses sink) Max RPM I could get it to read was 150rpms but then it loses sync and drop and then comes back.

Here is a datalog of it cranking, relay continually clicks as it cranks over for some reason

Can you go into Diagnostics and High Speed Loggers and take a composite log of attempted starting. It is loosing sync a lot.

What firmware version are you running?

[kamotors]

OK so forgot to update, the car is up and running I just needed 12v to the injectors.I got this car running the MS3 Pre-1.4 alpha 2+ 20140709 15:01BST

motor is out of the 2005 outback has avcs and avls (currenty unhooked as im having trouble with getting all to trigger but i want car running perfect first anyway)

Since this motor is the Subaru H6 I believe the sync loss is due to MS having the wrong settings, from what I've read the EZ30d motor has 36-2-2-2.....but, here is what I've dug up ---the ez30d uses 9teeth-2missing-10teeth-2missing-1tooth-2missing unlike the 4cyl subarus.


here is a datalog of it running, voltage seems very low and i'm not sure why. car is extremely slow, yet in neutral response seems quite good and car can rev freely. i've driven the car several times, battery seems to hold a charge. i'll get more data on it when i can. My alternator(3 wire) gets its reference from my fuse box, is that ok? also the line that normally goes to an alternator light is left unhooked( its outputting 6v) and so is the 3rd wire which I believe should normally go to the factory ECU.. this car does not have a body harness or gauges so not sure where i would route that line to.


this car really has nothing to it so not sure why the voltage drop. car doesnt even have wired windows or wipers..(thanks p.o.)

The current pre-1.4 alpha could should support the Subaru H6. Set 36-2-2-2 and 6 cylinders and it automatically expects the different wheel pattern.

it was a firmware issue! Well at least a huge part of the issue it seems. now only one missed sync and that was because the battery died ( alternator is only outputting 12.8V )

car started better, idled better until it got warm in which case it was idling too high, it was running leaner now so I added fuel just to go do a datalog (added around 5 everywhere to bring the AFR back down.)
here is a new datalog, the TPS is still having issues it basically slowly rises and maybe gets to 100 eventually:(


This is the firmware I was given and was running on-Id: core.ini,v 1.303 2014/06/27 21:40:59

I got this one today from another thread about this car http://www.msextra.com/forums/viewtopic ... 25&t=56429
Id: core.ini,v 1.304 2014/07/08 11:17:07

and car runs much smoother, just needs lots of changes to the maps now that it actually has the correct firmware.

Here is the newest datalog

[jsmcortina]

Please try the CURRENT pre-1.4 firmware. (pre-1.4 alpha6 at time of writing.)

You can find the version number in the title bar of TunerStudio:

are you saying I should use this version? I believe I tried it when I was searching for the correct file and it resulted in errors, I'll re download and see if it works. should I just create a new project, load this firmware and then load my tune and send to controller?

[jsmcortina]

Yes, try that version. If you get "errors" please post up what they are.

James

[kamotors]

I got this message when I create a new project with that firmware and try to connect.

This is normal. Press "update ECU definition", and you will be presented with a difference report.

[jsmcortina]

Basically follow the line in the dialog that says
"To correct this, update the ECU Definition in your project to match that on the Megasquirt"

You may need to browse to the ms3pro.ini that is provided in the firmware zip file.

James

[kamotors]

I tried that and came to here

I then browsed and got the firmware file and when I used that I got this message

Looks like you didn't flash the ECU with alpha 6, but rather alpha 2+?

[kamotors]

the car has always been on 2+ this is the thread with info on my car (whodwho did the repairs on it)http://www.msextra.com/forums/viewtopic ... 25&t=56429
Its just how I got the car, what steps are needed to flash the ECU to alpha 6?

[subwoofer]

Follow the instructions provided with the firmware you just downloaded.

[jsmcortina]

Instructions are also in the Megasquirt-3 Setting Up manual. See section 2.8 onwards: http://www.msextra.com/doc/pdf/html/Meg ... .3-18.html

got it, its up and running on the newest alpha 6 now. here is a datalog I really got to rewire alternator before doing mush else, TPS still giving terrible signals.

The only improvement with all the firmwares I've done today seem to that the idle is much better, car still makes no power at anything above 1/4 throttle, only reaching around 80kpa at WOT, shouldnt I reach 100?

[kamotors]

Well ,I'm completely stumped I rewired the alternator and now it actually charges the battery but the car WONT idle!

I spent a few minutes trying to dial it in but nothing worked, I went to shut the car off( battery Kill switch) but the car remained running and magically it all of a sudden idles perfect....no shaking or anything, I go and unhook the battery and its still running, I then discovered the alternator was giving power to the wrong side of the switch so I couldn't turn off the car I unhooked that and it shut off as expected.

I put it back to the right side of the kill switch but the car still will NOT idle with the alternator giving the battery power. I'm now at an almost constant 13.8V but the car hates that.....

the higher the voltage the worse the car runs. Here is a Datalog of it not beign able to idle.
