I always choose Megasquirt...every.single.time. You just can not beat what you get for the price. You get port or TBI injection(your choice) full timing control either with a distributor...or eliminate the distributor and use a crank trigger(your choice). You get full self-tuning capability, you get either speed density, mass air, alpha-n, or some combination thereof(your choice...blended alpha-n and speed density makes the best solution for ITBs for instance). You get full boost control capability, nitrous control capability, traction control capability, etc etc.....heck, you could even set up an output to turn your radio on under cruise conditions and turn it off under heavy acceleration automatically so you could listen to nothing but the exhaust if that is what you wanted.

The point being of course that it has the most flexibility of any choice out there....the downside is that the learning curve is steeper than something like the Holley Sniper, but for those who want the most control...you want a real standalone like Megasquirt, AEM, Motec, etc....but with even a pre-built top of the line megasquirt unit costing $650-750(depending on whether you need the expansion board to run cam phasers and the like for a Coyote) it is simply the best deal out there if you want full capability(if you don't mind assembling the unit yourself you could get one for $500-640, again, depending on whether you need the MS3x expansion board for more complicated engines)

Guys, I AM looking at the Megasquirts amd the Haltech, in addition to the Dynamic. The Dynamic is in the lead at the moment because it uses a very available GM box to start. I fugured if I went with something like a factory setup, I would be able to get sensors and such easily. And on availabilty, the E85 stuff is EVERYWHERE around me, and cheaper than regular. Getting it would be no problem. From what I have been able to learn, it has about 80K BTUs per gallon as compared to ~120K for gasoline. Mileage loss is highly dependant upon compression, with 9.5 or so losing you 30%. If the compression is raised, the rate of loss goes down. But if you have 12 to 1 or more, you aren't running gasoline anymore. I'm okay with that. I'm not sure about the corrosion fears, I have not seen that happening. None of our customers using it have had any trouble. The METHANOL guys, however, have LOTS of problems. I wouldn't touch that stuff. Turbos & supers aren't really in my budget, but I think I could do a 13 to 1 smallblock in a cost effective manner. LSG

You can get very good results with E85....but I would hesitate to go exclusively E85 if you ever drive the car long distances....but with MS(or Haltec, etc) you could simply have 2 different tunes, one for regular gasoline and one for E85....but you would want to limit yourself to about 11:1 CR to be able to make that feasible....you would also need rather oversize injectors and an adjustable 1:1 fuel pressure regulator to give yourself the fueling flexibility. I wouldn't worry about corrosion as much of a factor with E85 as long as you are running modern fuel system materials.

P.S. As far as sensors goes...Megasquirt uses standard GM sensors for IAT and MAT, and if adding a crank trigger setup to an engine without an existing setup, you simply choose whatever OEM sensor you want...as an example...last time I did that, I ended up using a factory Escort 1.8L VR crank sensor....no custom sensors needed or desired for MS, couldnt say about Haltec

I hope to not find myself in a spot that I need to run gasoline, but if the WCTU, and the Rockafellors, were to suddenly come to power and E85 was no more,.....a 302 with small ( 6cc ) domes and 54 cc heads from a 289 gives 12.2 to 1. Thats gasoline never. But, I got some 1979 302 heads that the shop was going to toss out,.....they have 70cc chambers. If I swapped those same heads onto the small 6 cc dome pistons, I am suddenly down to 9.6, which is just fine on gasoline. So, it would take a few hours, but would still be do-able if I HAD to do it.

92 5.0L longblock, thermactor bumps ground and port matched to exhaust gaskets, 70mm throttle body/egr spacer, stock MAF, stock 19#,T5 from same car, used but not abused Hooker long tubes, cheap used 2.5” Summit Racing exhaust.

Wanted to do it since 92 when I had an 86 GT convertible. Just fun to shift gears.

Stock A9L ecu...runs great, no issues.
Street driven...reality checked myself.😁

The Blue '65 has a Sniper sitting atop it's 450hp 331.

The rusty '65 will have a very mild garage built 5.0L with the factory EFI! It may eventually see a paxton or vortech if I 'need' more oomph. The stock EFI stuff was all included with the motor I got for $500.. including the harness and ECM. Win!

E85 is great for forced induction. Even despite only having a 105 octane rating you will find it hard to get your engine to knock from a lean condition. Ethanol is just a different animal than gasoline. It also takes more ethanol to produce the same energy as gasoline so don't get too caught up in the price difference. For the same reason, you will need more pump and injector on E85 at a given power level.

If you aren't running forced induction don't use it. It's not worth the effort.

If you are going to run a crazy N/A engine, Methanol is the fuel you want.

This is the tank I am using.

View attachment 748299

I have been planning on using that tank myself. What size pump comes with it? I haven't been able to find that info...it is MUCH cleaner and a better solution than running lines inside the trunk....and the price is also far better than other EFI tanks.

Methanol is more corrosive though...not sure it matters for a car that sees little street time though.

Jdub, methanol is very nasty and corrosive stuff. I was thinking of a daily driver, in any temperature, not being used December to March when there is snow and salt on the road. The idea that you need more ethanol is not exactly correct. It is true you need more ethanol if you are running lower compression ( less than 10 or so ). But if you raise static compression past something like 13.5, then things have about evened out. But one cannot do 13.5 to 1 on street gasoline, on E85, it would seem that you can. LSG

Wideband gauges use a Lambda value of 1.0 to display 14.7:1 air/fuel ratio. When the Lambda value is 1.0 it shows 14.7:1 regardless of what fuel you're using. At 14.7:1 on the gauge with E85 you are really at 9.9:1. 13.5:1 is a Lambda value of around .920, or about 9:1 on E85. It is true that you can run much closer to a 1.0 Lambda on E85 than gasoline but you're still using a far larger volume of fuel.

I've run E85 in a performance application before. You always start by scaling your injectors by 43% from the gasoline setting and tune the maps from there.

I wanted to do something a little different than the normal throttle body set-up. I have not ruled out E-85 but could easily upgrade to a higher compression short block (haven't built it yet). My intake is from Hogan's using a long runner, single forward facing throttle body with a distributor-less coil near plug ignition. I had the intake built to fit under a stock hood on top of a stroked 351W aimed at a broad, flat torque curve. I have not purchased a controller yet but was leaning towards the Holley Dominator ECU for it's capabilities.

I'm done with TBI and I'm lazy. I just installed the Edelbrock Pro-Flo 4. Unbelievably better out of the box than the previous FiTech ever was. No official E85 support, but that doesn't seemed to have stopped anybody. And it looks cool, to me anyway.

Nice intake...I am sure it had to cost a pretty penny....judging off of what I have spent on my unfinished setup. The runners look shorter than a stock 5.0 manifold by a significant margin though(not that that is a bad thing...probably raises the powerband by a couple thousand RPM). I do love crossover intake manifolds...they are so much prettier.

Wicked...you can find specs at Rock Auto and NPD.
I don’t think pump is E85 rated.
Besides volume rating, some plastics melt with E85 from my understanding.

Holley has a pump that uses a sock (no need for a sump) and replaces stock pickup as well...I think it is rated for E85.

I thought of doing same thing for 5.0 and keep it under stock hood.

What throttle body?
What ignition system?
Can EEC IV ecm be adapted to distributorless?

I am going to run a 102mm single blade (03/04 cobra spec) or adapt a Coyote drive by wire setup (probably what I'll end up running)

As stated, the Holley Dominator ECU to control everything

The cam sensor is basically an Explorer part made to fit a 9.5 block. Since it was a part based on a production piece an ECU that will read it and fire the coils should work.

An 8.2 deck will be much easier to fit under a stock hood. You'll; have tons of room.
