We were asked if Team Chevelle could help with gathering data about EFI from a large aftermarket company and thought it would be a good idea, besides, he is a TC member :D

It applies to carbs as well, is very short and will help out the hobby.

The survey is now over. Thanks!!

Al

done!!

Me too!

Me three...

Hey Al,
I tried to send it in, but it gave me an error "Missing Reference - Access Denied" Any ideas???
Thanks,
Bill

me four...

Me five

Not sure if mine went through also.

Bill, you must have hit it while I was making a minor change. I modified a couple fields and added the option for your techname.

Thanks guys.

done

Me seven ( I think smile.gif )

John

me too.

Done. I'll take a free one!

I recommended the HP950 :D

Completed

I'm in. smile.gif

950HP & a Performer RPM :D

Gaz

DONE

What the heck, it's only money! I'll take two.

Our everyday vehicles are fuel injected and there is no denying the smoothness. How much power is there to be gained with port injection over a well setup carb and intake? For the price of fuel injection it would want to be considerable. I guess a big block with injection would have a nice wow factor at the cruises.

Done also.

I would be more interested in getting PROOF that the EFI set-up could perform very well on the street and highway as opposed to the carb'd set up. I'd rather them advertise that the systems have been road tested in the real world, on a real daily driven car. All this stuff would be more important to me than if they advertised a certain amount of HP/TQ over the carb'd system. Everyone says you can tune a carb to HP/TQ the same or better than EFI. The point of EFI is the ability to tune with pin point accuracy and reliability/efficiency of EFI.

So instead of advertising power, I offer these up for a change:

1. Real world road testing.
2. The ability to super-tune the fuel and ignition curves to your liking. Ability to store different codes (one track, one highway, etc).
3. Efficiency as compared to a carb'd set up. How much MPG better can it do?
4. Ability to MATCH the HP/TQ numbers of a well tuned carb and ignition.

That's my take on it.

I tried to submit but got some goofy error.

Slowpoke,
I've tuned dozens of EFI engines, some back to back with a carb (I'm talking 900 HP Dominator equipped engines). Here are some comments.

1. Real world road testing - there are 1000's of miles of real world testing on many of the aftermarket EFI setups. They work. If you are in KY stop by and I will give you a ride in my Nova that will have a 255@.050 solid roller 491 BBC in it. It will fire right up at 30 deg F and drive perfectly, it had a decent solid roller 388 EFI engine in it that is how it performed.
2. All the laptop programmable EFI system have the ability to tune the fuel and timing very precisely. If you have a wideband O2 sensor you can tell it what A/F to run at at different loads and RPM points. No lean spots, no rich spots, period.
3/4 - The KEY to aftermarket EFI systems is how well it is tuned. How much MPG?? Take a 355 with a pig rich carb and of course the EFI will make a lot more MPG if it is tuned right. Take a super tuned Q-Jet that runs at 15:1 and if your EFI runs at 14.7:1, you might not see much. The EFI give more ability to use an OD trans which is a key to better fuel economy.

Take a dead-on set up carb that is fully tuned and they will make about the same power, that requires a lot of knowledge and changes, along with a wideband A/F meter to know what you are doing with a carb. The hard part is make a lean area correct and another goes to rich. With EFI the tuning points are all independent. 90% of the time I can beat a carb by a little.

There are no cut-and-dry answers which is a frustration of mine when people make blanket statements. You can't say it will always do this or that. Depends on every application. That goes for a lot of parts for that matter.

To truly appreciate aftermarket EFI you have to ride/drive a car with it. Nobody is going to pay $2000 for 10 HP, but there is a lot more to it than that. Take a car with a big solid roller that idles great at 800 RPM cold or hot in neutral or in gear.

I go to the track with a laptop and in 1 minute stick a "track only" program in it, race and change to another file and go home. I have an internal ECU datalogger I can log passes with and see wheelspin, converter performance, shift points, etc.

There are a lot of other benefits over a carb.

Just entered mine Al.

Completed mine too.

There are a lot of other benefits over a carb. That's exactly what I'm talking about. I could care less about a 10HP claim, you can get your carb worked on or switch to another carb to make up for that. That's not what counts. What counts is what you said, all the cool things you can do with the EFI set up. Compatibility/reliability and creature comfort is what you're paying for in EFI.

Done.

Hope it helps.

Done and hope it helps also!! I'd like to be a part of the development!! :cool:

Got my $.02 in as well.

What does that have to do with EFI?

Done! graemlins/thumbsup.gif

Put in my setup and opinion. Am gonna be standing by my front door waiting for the tech team to come and install my free EFI that I suggested they do to get my endorsement. I'll keep the lights on for you.

Done

it be done

graemlins/thumbsup.gif Done

So be it, I reckon so!

Done 2 or 2 Done
one of those.

I have been seriously tinking of fuel injection.
Has been too expensive though. And, It really should not be. Espically with the throttle body type.

Done graemlins/thumbsup.gif

I'm in

Done!

finished

I've tried several times to submit the form but am still getting an error message just like ZZ69chevelle. :confused:

I think going to an EFI setup is a little like going to HDTV. It's new for a lot of folks, a bit pricy now, but if more and more people take the plunge, prices should come down as manufacturers recoup their R&D costs. Also, EFI usually (in a really tunable system) requires a least a basic comfort level with computers in your car, which may be the more challenging factor for manufactures to contend with. Even though my system is not on the road yet, my initial tests show a scary ammount of throttle response, bucketloads of useful info to dial everything in, and having a laptop mounted to your dash really gets the 'tuner' crowd looking! graemlins/thumbsup.gif
Just my $.02
-Bill

Done, and I just went to HDTV, does this mean...well maybe not.

Kewl, maybe they will send out a new EFI to all of us who replied!!!!

Survey done! However, I'm claiming dibs on any prototypes that may come for free. After all, I am a starving college student....

Ryan

Gotter done

Me to, me an EFI, and I will build a forced induction with it.

Done.

I'd be willing to try it (even though I don't really like electronics in my old cars) if they could sell a whole system for what I can buy a top end Holley for. I know the prices have gone down a lot in the past few years but until I can get one for about a grand, I won't switch. Oh yeah, and even if they are only a grand, I still won't buy one that's not MACINTOSH COMPATIBLE!

Great Survey! Would like to see others suggestions and what they thought! :cool:

I dooed it also graemlins/thumbsup.gif

done!

It was short, but not as enjoyable as my first digital exam

Having an ECU in your car is no big deal. I mounted mine on the outside top of the glove box liner. You wouldn't know it was there except the comm cable that lives inside the glove box now. And you guys are right, the tuner crowd doesn't know what to think when I'm clicking away on the laptop at the car wash.

They think you are dialing in your NOOOOOOOOOOOOOS....

LMAO

Andrew

Thanks for the responses.
If you were thinking about filling it out but haven't, this is the last day for the survey. I'll be removing it on Thursday, the 24th.
