EFI running from a PC?

Daggar · Dec 27, 2006

Ok so...

What I got out of that was that the EEC will run EITHER the EEC tune OR whatever is loaded into the J3 slot on the back of the EEC but not both and not parts of each. Is that correct?

As I understand it... That is correct.

The EEC J3 tuners don't do anything to the internal ECU memory because they cannot. They are ROM, or Read-Only-Memory; it cannot be erased or altered in this case. The new fuel/spark maps are on the chip in the J3 tuner. When the EEC detects something plugged into the J3 port, it only runs what is on the external chip.

.

I don't think we disagree
Maybe I didn't phrase things properly?

So you are going to try and convert the SVO computer to run a single cylinder?
I thought you had decided on MS for that?

1. I wasn't disagreeing. You said the TwEECer is the only EEC tuner that doesn't use .bin files. I was just speculating on the how and why that is done.

2. I'm not going to use an EEC for anything but a Ford engine. I should have been more clear in saying that I was probably going to get a J3 tuner for my SVO and play around with tuning that. In lieu of endangering the rare and expensive SVO ecu, I will probably use the Merkur PF2 instead(that cost me $13).

I actually could alter the PF2 to work on the Briggs, but MegaSquirt is so much easier and I already have it hooked up.

EDIT: I almost forgot....

Video!

This thread is awesome. I can't believe I missed it. Thanks for resurrecting

I'm still waiting see you screaming around the yard, grass flying everywhere, from the world's first turbocharged lawnmower.

OR the big grin on your face after smoking the tires all around the gocart track on your turbocharged gocart.

Unfortunately, neither of those is too likely to happen. This engine was destined to be a proving ground for my EFI/turbo idea. It will most likely die a horrible death under high boost, high rpm, and high power on a DIY dyno......being videotaped, of course.

I also plan to get a Briggs Vanguard v-twin and do the same thing minus the horrible death. I can at least get billet rods for those. They have pressurized oiling so turbo lubrication is simple and I could try to get power AND longetivity. How about taking a 22hp Vaguard and quadrupling the power on gasoline?

Just get a megasquirt and be done with it. Period.

I ditched the Nissan ECU and just went with MegaSquirt(in case anyone hasn't seen my sig). LOTS easier...

Any one or ones willing to try this? I am willing to host the porject.

65ShelbyClone · Dec 30, 2006

Try what?

i often wondered if there would possibly be a way to put a home pc in an automobile. I mean, it's all converted to 12v anyways, after it leaves the power suppply.

instead of a lap top why not incorperate a moniter in the dash or in front of the dash and run all the power cables etc to the trunk area or back seat area if the back seat were eliminated .......that way you could build a speaker enclosure, to mount the "tower" in.
Since some companys have lap top data logging anyways, I dont see why a cheap CPU etc couldnt be used in this application and it be basically onboard live dianostics?
keep this thead going.......this is very interesting!
Jack

Just a thought on your idea. Why not incorperate wireless?

65ShelbyClone · Dec 31, 2006

I know there is a Blue Tooth addition for MegaSquirt, but it has limited range.

Do you mean use wireless inside the car, or to send data to a stationary computer?
