MpGuino keeps resetting. - Page 3 - Fuel Economy, Hypermiling, EcoModding News and Forum

I had another idea while sitting here trying to figure out WTH is going on. What about adding a couple diodes to the signal wires? Maybe the problem isn't a surge in but a surge out. When I am turning car killing engine maybe the injector or vss is looking for a ground and the Guino is there to provide it for it. Just add a couple where I have the arrows to. dcb hope you don't mind me using your schematic image.

I don't mean to bridge threads, but I was concerned about a cold solder when you said the vss stopped working.

Do you think maybe you could plug it in on the desktop and poke around a bit with a wooden skewer on all the leads/connections and see if anything reacts badly to poking?

Mine hasn't frozen up in ~400 miles... though it's been cooler, I'm headed back south (relative, lol) and it'll be in the 90s again....at least for a few days. Maybe it's finished acting up, who knows?

Well I am officially un-soldering everything and starting over. This time I am using schematic for pcb style. I will use my Iduino board to program then pop into pcb board. I have too many jumper wires on my current shield setup and causing alot of problems troubleshooting this. I will report back in a few days. Thanks for the help guys. I need a restart from scratch, maybe that will solve it.

I completed my scratch built using dcb's schematic. Test drove last night and seemed to work a lot smoother the instant speed was not as bouncy. I am guessing my old board was just not right somewhere. Time will tell if I have any problems. I don't ever remember the other one running this smooth on readings though, this one is smooth as butter on readings no more jumpy readings. Wish me luck.

That is a very encouraging report

So far no resets or lockups, except when I tried to reset tank while moving. I imagine you shouldn't do that though. So far the rebuild is the best thing I could have done. Will test more tonight though.

I drove 27 miles tonight 20 in the country and 7 in town with P&G and no Resets so far. And 8208 on VSS seems pretty dang close. I recommend to anyone having problems with this to just either buy the kit or build the pcb version and use the schematic in that thread. It cuts out alot of the extra connections that can cause a problem.

Well I had a lock up yesterday night and brought it home opened the case, and Voila!! My left switch connector had made contact with the board. So I broke out the hot glue gun and covered all of the backside of the board and switch connections, problem solved.

Hot glue your Guino's please save yourself a headache later.
