An EFI section would be great!

[PonchoV8]

EFI, please. I don't want a carbed, boosted engine.
I came from the Z world a decade ago where an efi boosted 240Z was common.

[Mjohnson23]

I just purchased a Powerjection 3 unit myself this week with future plans to boost also and will be exploring that area more these next few weeks before install it. Very helpful guys at professional products on their site i see forums where they tweak peoples maps for them to download into their units to help cure any problems they may have.

I gots 2 thoughts about EFi & optimal mixture:

1: Just how superior is the MSD FI system (PWM fuel pump control !!) compared to ALL other kits?

2: I like the idea of an O2 sensor kit for mu carb application(s) to monitor/ log mixture during the 1/4 mile run or driving. NO feedback to the carb needed...HIS

[Fishin2Deep4U]

The PMW control had done distinct advantages depending on how it is configured. Basically, you can reduce the duty cycle at low fuel demand periods. This of course allows for a pump that is not driven as hard and cooler fuel. Also, you could possibly use different pressures to allow for a longer injector duty cycle at idle and raise the pressure at WOT to reduce duty cycle for high rpm.

So, basically, the fuel pressure becomes part of the tune. Now I really expect all this is to facilitate a dead headed fuel system for this efi system.

The O2 sensor is a handy tuning tool. Every engine seems to like something different, but at least you have a bench mark to tune from. Check out 14point7.com. I use a setup from them for my megasquirt.

And speaking of megasquirt, even a cheap ms box can data log and with a wireless bluetooth adapter, can send logs out to a virtual dash with any gauges you want to a smartphone or tablet. Heck, you could even stick with a carb and gain ignition timing control. Lots of possibilities. I am sure other systems can perform in a similar fashion, just not sure of the cost.

How about they just change the name of this sub section to "restomod" or "pro-touring" Get some more sponsers to show up and answer questions about products. Lump it all together with aftermarket suspension, efi, boost, LS engines, 5/6 speed swaps, vintage air, big wheels, big brakes etc until it gets a big enough following, then seperate them out if needed. I'm willing to bet it would draw a good crowd. I would be here daily. There are a lot of guys on the PT.com board that are building Pontiacs and lets be honest, this is the direction a lot of guys are going anymore. The only rule would be no bashing. We all know the Poncho world is full of some hardcore purists and bashing would ruin it before it started.

Brian Rock's GTO is setup that way.

Well, i'm finally mustering up the courage to modify the valve covers I made a little while ago and run 4 x LS1 coils on either side. In the engine at the moment currently is a modified MSD Pro Billet for cam sync, but I've got a spare points Mallory distributor which i'm going to remove the points and advance assembly out of and see how hard it would be to adapt something like this for cam sync rather than cut up my Pro Billet distributor - http://www.diyautotune.com/catalog/h...sor-p-489.html



As the mallory distributor is a small body thing, it shouldn't look too out of place hopefully.

Megasquirt 3X will be firing these puppies one at a time too

[Ollie]

Is something like this what you have in mind.

[krisr]

Yep, that looks like a stock Pontiac dist body though? The mallory unit I have is alot smaller than a stocker. If I could get away with it, i'd love to put a cam sensor on the timing gear and just have a small plug to drive the pump up the back and nothing else.

If I could get hold of an old MSD CPC cam sync plug, i'd love to cut it down, put a Pontiac gear on the end and try make it work...

[Ollie]

This is not a cut down stock distributor.
This is the lower half of an Accel two part duel point distributor PN37102.

[TheSilverBuick]

This is on my Buick 455 so it doesn't translate perfectly, but you'll get the drift.

Trued up the inside of the crank pulley so it was flat, mostly scraped the paint off of it, and opened up the trigger wheel off a ~'90 Ford Escort. Pinned them together.





Some square aluminum tubing and rivets for a bracket (I can't weld aluminum). Same sensor, just a different color.



I've made two different types of cam sensors now.

My HEI mod. Grind all the teeth off except one on the reluctor and pick up coil. Works like a champ.



Or what I did on the Pontiac OHC straight six, which I haven't tested yet, but am sure will work. Cut down the distributor plate into a tab and grabbed a cam sensor from a late 90's GM 4-cylinder (from the junkyard..).


I finally started on the valve cover coil pack mounts. Kind of goofed the alignment on cylinder #2, but figure I'll care less when it's hiding behind the A/C compressor. Simple steel tubing stands tacked in three places to the valve cover with a nut tacked welded to the top of each for the screw.

[krisr]

I built up the courage (thanks to a couple of JD's) and decided to attack my valve covers with the TIG. I had a spare set of LS1 leads lying around so I decided to recrimp the coil end of the leads onto my cut down MSD's. Its taken me an hour to do 2 leads

Welded the other cover but a weld cracked 6" away from where I'd been welding so had to play "chase the crack". I'll need to repolish that cover again, but it's as good as done now.

[TheSilverBuick]

I just got my distributorless system working yesterday (Buick).

Running a powerjection 3 setup here. Would have been nice to have a section to turn to to evaluate all the alternatives as each manufacturers website is only their product specific.
For example it would have been nice to know that almost universally it is understood that the fuel pump and fuel filter supied by PP with the kit won't work. The fuel on demand system really is short lived and almost always ends up in a return line setup. Oh don't forget the throttle position sensor and temp sensor almost always need to be replaced right out of the box as the supplied units almost always fail. There own tech guys( should I say their old tech guys as no one from the company posts on their forum any longer) admit that it's not a self learning, plug and play system.
With all that I have been able to navigate into a setup that now seems to run very well. Probably should have cut and run earlier instead of patching this together but was into it for too much cash to change directions.
Anyway, not bitching but would love an EFI section so others can get non biased accounts of how each of these setups run.

I think what I like most about MegaSquirt is the support thats available pretty big forum and seems there is always someone who has the right answer when you need it.

Agreed. This is what attracted me to the MS family. There are just do many different installs on so many types of engines. It's nice to have that depth of knowledge when trying to do a relatively "simple" type install.

[krisr]

All mods complete - made up the leads from a set of old LS1 leads I had laying around (coil end) and recrimped onto cut down existing MSD leads with a bit of persuasion - all ohm'd out fine.

Have modified the wiring harness to add the trigger/power/ground for the coils and add in oil pressure & fuel pressure monitoring. Fuel pressure works a treat, oil pressure I won't know until I get it running.

Once I get the spare mallory distributor modified/machined down so it's just a true cam sensor, this will mark the last mod I made to the motor I think

[Ollie]

Hay, guys, We should be posting these on the forum to help get the EFI posting count up. Not hidden 5 pages deep in a sticky.

[Ollie]

I like what British V8 has done with a Ford cam position sensor.
This is posted on the MegaSquirt forums.
http://www.msextra.com/forums/viewto...p?f=71&t=51205

This was fabricated for a Rover/Buick V8.
No reason why it could not be done for a Pontiac.
