3rd gen 3sgte bench test, megasqurt and EDIS Options

[WannabeGT4]

Couple of videos in there of a 3rd gen 3s being tested with the megasquirt and spark with the Ford EDIS Iginition setup which is probably what I'll end up running on mine when ever I find some time and money to get started.

omg...thats just amazing. what kind of crank power did it make?

That's pretty cool... I don't see the advantage of using EDIS, since MSnS can do spark with the stock stuff also, but cool. Maybe I'll start posting pictures of my setup once It gets closer to getting done...

No clue. Just came across it while I was searching for 3SGTEs with megasquirt EMS. He did say it ran a 13.2 @ 102MPH. So it's probably upwards of 275 HP.

I think a 13.2 in a ST205 is going to need more like 340bhp at the fly.....

I think that using EDIS would be more reliable and simpler than modifying and rewiring the old fashioned cap and rotor. Fabbing simple brackets for the crank sensor and welding a 36-1 crank trigger to the pulley is simple stuff and seems to make tuning a whole lot easier. There must be a reason newer cars are becoming distributorless.

What is your setup exactly? I'm sure we'd all love to see some pics. At least you have something started. It looks like I won't be able to begin for a few more months.

Actually it was in a mkII MR2 which weighs about 2800 lbs so using this calculator:

It ends up being quite close to my original estimate at the fly wheel. Of course not exact but not 340. I'm sure that 340 is pretty close for a GT4 though once you factor in the added drivetrain loss and weight of 4WD. Not that 4WD is a bad thing

It's a great thing until you look at weight, complexity and parasitic losses.

Hell, it's still a great thing........

EDIS isn't the best DIS system IMO. I'd only rate it on par with with typical distributor systems because their adjustability is quite limited without a good piggyback. It's also a bit more tricky to wire up and set-up... unfortunately. But COPs and DLI and such which use different types of triggering systems are quite efficient and are better than distributor systems.

My set-up...

4AG 20V silvertop rebuilt, modified, with MSnS with EDIS. I'm using EDIS because this set-up is going into an FR layout (AE86) so eliminating the distributor saves one from chopping the firewall. ;]

Well we're not talking about EDIS in it's stock form so the piggy back isn't an issue. I don't know why you think EDIS is tricky to wire up. It's a simple issue of two wires from the EDIS to the MSnS and then power to the coils/EDIS module. I definately think it's better than any distributor system simply for the fact that there is no cap or rotor to wear out. It seems so much simpler to me and the adjustability will all be controlled by the MSnS.

Nice looking Silvertop. How are you going to balance that pulley once you atach the 36-1 "gear" to it? That's the biggest obstacle I'll have to overcome.

EDIS and The dizzy aren't very different at all to wire up. EDIS just needs some extra attention, but I'm just saying you know... there isn't a point overall to switch to EDIS, when toyota DLI or COPs or something else could have been done. In the end, all systems provide spark.

As for my silvertop, I had because of the differences in size between the crank pulley and the trigger wheel, I had a machine shop line everything up and weld it together. I'm not too afraid of minor balance issues when it comes to the crank pulley on Toyotas. There's a whole ot of stuff affecting the crank and if a pulley mod was enough to throw the crank out of balance, so would a flywheel, belt tension, engine load, etc. The engines are plenty tough. ;] That's a VERY old picture BTW... i'll take some later.
