AEM V1 vs Flash ECU? Which should I have?

[J. Fast]

Link to relevant section of the CFR?

FED say's it's okay... ofcourse state's can choose to implement their own regulations but a quick Google and here's the first 4 hits... I don't have all day so...


Georgia:

Alternative Fuel Exemption

Vehicles powered by diesel fuel or that run exclusively on alternative fuels (natural gas, propane, etc.) are exempt from having an emission inspection.

Georgia's Clean Air Force: Other Exemptions



Nevada:

The following vehicles are exempt from emission testing; Alternative fuel vehicles

Nevada Emissions Control Program



Michigan:

Alternative Fuel Vehicle (AFV) Emissions Inspection Exemption
Dedicated AFVs powered by compressed natural gas, propane, electricity, or any other source as defined by the Michigan Department of Transportation are exempt from emissions inspection requirements.

Alternative Fuels and Advanced Vehicles Data Center: Alternative Fuel Vehicle (AFV) Emissions Inspection Exemption



Missouri:

Alternative Fuel Vehicle (AFV) Emission Inspection Exemption
Vehicles that are powered exclusively by electricity, including low-speed vehicles; hydrogen; or fuels other than gasoline are exempt from motor vehicle emissions inspection under federal regulation are exempt from state emissions inspection requirements. (Reference House Bill 354, 2011, and Missouri Revised Statutes 643.315)

Alternative Fuels and Advanced Vehicles Data Center: Alternative Fuel Vehicle (AFV) Emission Inspection Exemption



Federal Alternative Fuel Definition:

Alternative fuel is defined as compressed natural gas, propane, ethanol, or any mixture containing 85% or more ethanol (E85) with gasoline or other fuels, electricity, or any other fuels, which may include, but are not limited to, clean diesel and reformulated gasoline... Alternative fuel does not include any fuel product that contains or is treated with methyl tertiary butyl ether (MTBE).

If the 'Fed' says it's ok, it'll be in the CFR.

These alt fuel vehicle exemptions almost always have a clause stating that they must be built by a certified shop or OEM.

Just knowing how the Feds are, I find it VERY hard to believe that all you have to do is drop some corn gas in your tank and tweak your injector scaling to magically have an emissions exempt alt fuel vehicle.

There's quite a few people who swore their state-registered JDM import cars were legal too, right up until the Feds came and towed them away.

if you run the car with a stock or evo maf for a while it should tune easily on the stock ecu. My car is not as radical as yours, but I do have ported heads, cam gears, full exhaust, intake pipes, ets fmic, DR750s, etc and the stock 99 tune with my injectors dialed in half way runs like stock.

That's the thing about the flashed ecu. It is such a good basemap. Yes, it won't make the absolutely max power right out of the box, but the car will be driveable, which I am not sure can be said for an AEM base map.

With the maf your extra displacement will naturally be mostly accounted for. Like I said it may not be completely ideal, but this isn't speed density where everything in terms of VE has to be calculated and spot on.

To tell you the truth I had enough of a nightmare with the speed density on the emanage ultimate that this feels too easy. Once I got some very basic mechanical problems on my car solved it started and ran with no bs.

Nope, you fill out a VIN Verification and Vehicle Inspection Form take it to State Patrol and have them mark the "Reason For Inspection" OTHER Right next to it Write "Inspection for Change in Fuel Type". State Patorl conducts the vin inspection. You then then use an ethanol field test kit that shows ethanol content percentage and they verify the percentage as greater than 85% and sign the form. You take the VIN Verification and Vehicle Inspection Form, the title, and registration to the DMVR and request a Re-Title to AFV (AKA alternative fuel vehicle). They change the fuel type on the vehicle title from "G" (which is gas), to "T" (which is ethanol) or "P" (propane) or "V"(etc) and viola, you're vehicle becomes a registered AFV. It's really that simple.

I have helped dozens of people thru the process, seeing how I was one of the first to read the fine print and actually do it.

[J. Fast]

Last person I helped was an S2000 owner on the 24th of April.

(On 4.24.2012 @ 5:13pm) Just in time as I have emissions for the s2k this month. Stopped by the dmv today with documentation, title, insurance...never walked out of that place so happy :-D. Emissions exempt for the life of the car as long as they don't change rules..

I did not itemized everything to the exact since I already filed my taxes for the year and not using the credit.


Thanks Jeremy!

The mods in chrome V2 are written with a simple hex editor. The most time consuming part was learning the language & syntax. Seems I'm getting over that curve finally though! The disassembly part is never ending...

So the guys doing this for other platforms, are they doing it by hand like this or has someone ported a C compiler or something?

[Jesters Deadd]

Has anyone used and tuned with both an AEM and flashable 98/99 ECu?

I will if someone will send me one.

I could hook you up. I have a for sale thread on 3si for some.

I am running 1000cc inj in my car on 93 octane and it idles and starts great. Is anyone running bigger injectors in their flashed ECU cars?

that's good to know, I was thinking of moving to an 880cc injector so I could dabble with some e85 at some point. It will be neat if we have switchable maps at some point and you could just flip a switch and go from 93 to e85.
