Hi Guys, wonder if you could help as I am having a nightmare! For the last 2 weeks my squirt has been failing on a regular basis, symptoms are:

Engine running fine then it just cuts and feels like I am only running on 2 cylinders (like a tractor!) sometimes it clears and sometimes it doesent (had to be recovered the other day. My car is a 93 1.6 with m45 SC, MS v1, LC-1 WB o2.

last weekend I re-soldered all terminals on the harness, stripped the squirt down and resoldered most connections, and its still doing it. Initially, I thought it may be something other that the squirt but I have changed the following:
Ignitor
spark pack
CAS
Leads
Plugs

I have also put my squirt on someone elses car with his and my harness and it still happens. I think it may be a fuel based problem as I am getting a spark when this happens. I have been at this now for 2 weeks and I am loosing the will to live!! Can anyone help please...

MegaSquirt never fails, this is your fault.

Sounds like the only thing you've never changed is the coils. Also sounds like one is going bad.

EDIT: Re-read last line. Are you saying you put your controller on his car and he has the same problem?

I blame your soldering.

+1. Double check your harness. I know you checked it once, but take another quick look. Also, did you clean the board with alcohol after you built it? I've heard of people having issues with the solder flux absorbing moisture and shorting out.

Baz

Yes, I put my squirt on a friends car using his harness then mine and it still does it.

I've checked it twice Jeff and yes I did clean the board, if it isent the harness any idea which area of the board I should be checking?
Cheers

Baz

You may be right but I am pretty good at soldering and I have checked it thoroughly, any idea which area of the board could be causing this?

Check the ground below your TB, that was causing problems for me.

Heres a log of it happening:

This may just be a coincidence but this problem has only started since I stated to use the auto tune feature on tunerstudio, also, when I get a difference report nearly all the info is missing (rpm, map kpa, choose ts settings etc, all the buttons are missing) this also happens when I try to save the tune, I tried it on a friends laptop - same thing, does anyone else get this?

Could it be that my MS processor is corrupted/knackard? I have reflashed the firmware and downloaded a fresh copy of TS - still got the problem.....

looks like your spark angle goes crazy high, hard to see...upload your MSQ and the log file please.

Baz

Sorry but do you mean this?

attach the actual log file and your MSQ to your next post. go to advanced and then attachments and upload them so i can look at it locally.

Baz

Baz

oh yeah they changed the damn file extension from xls...let me fix that.

Braineack

I see weird values in your wheel decoder settings, and you should turn baro corrections.

Baz

I can upload the msl now but how do I get it into the message?
