EFI Experience Thread

[25psi_Elise_Killer]

Anybody have access to E85 and going to try to tune for it? Once you try it, you won't ever want to go back to pump gas. It behaves like C16 race gas,timing can be advanced a LOT higher compared to pump gas, runs a lot cooler in the cylinders compared to regular gasoline, and its cheaper than 87 octane!

[GTsRasta]

But the gas milage AND miles/dollar ratio is worse than pump gas, and (as you pointed out in your own thread) you're going to gamble in order to figure out over time whether the fuel lines will hold up or not. Lets see how long you last first haha.

But if things really do hold up...I think I might just run this stuff alone in my car. The only E85 place here in Long Island, NY is just 12 miles East of me, and I think they ship extra fuel to people's houses.

[25psi_Elise_Killer]

Yes it doesn't make economical sense compared to pump gas, but compared to race gas, its a bargain since it makes similar power to VP C16 gasoline which is going for around $14/gallon in SoCal. Even if you don't change boost levels, there's still significant power to be made from it. Plus the engine idles/runs smoother A byproduct of burning E85 is water. So, its just like having the benefits of water injection, without all the gadgets/pumps/lines needed to run water injection. It'll keep the fuel system cleaner since its 85% alcohol.

VP Racing Fuels

All VP fuels are available in 5- (19 liter), 15- (56 liter), 30- (113 liter) and 54-gallon (204 liter) pails and drums except where noted.

C16
Used in turbocharged engines, blown engines and nitrous applications with CRs up to 17:1. Recommended by the top nitrous oxide companies. Spec Fuel for NHRA Comp Eliminator.

• Color: Blue
• Motor Octane: 117
• Specific gravity: .735 at 60° F

Here's my most recent dyno run on E85: Finally, E85 In Los Angeles

Now that you guys have a standalone and the tools needed to datalog and tune, DO IT!

Guy, we've a very phobic group regarding water/meth injection... forget about a complete fuel-system conversion, not happening...
Perhaps in the future...

Be good,

Err...E85 is a totally new fuel...not a water/meth additive...

But as for W/I, we have an automatic GTS running just as much boost as ronin (14.7 psi) with just W/I alone on his built block...try doing that without any detonation supression.

I joined the EFI brigade. Just looking for something to do and maybe a few more HP's. I'm very impressed with the wiring and connectors.

Thanks to Phil for answering my 200 questions.

Thanks to Dave for posting some helpful pictures.

Thanks to Kris at DRS and Fred at Blackwatch.

This post subject to edit if my car doesn't start.

I'll report back with dyno compares etc.

[turbophil]

You know you're welcome to call me all you want...

Speaking of pics:

Here's one of my manifold... From left to right (taken from the rollbar looking down): cylinder #1 intake runner has intake thermocouple for datalogging and Dash2 display (.5 second delay), runner #2 has the dedicated EFI IAT sensor, #3 not used water jet, #4 MAP pickup for EFI and datalogging...

The other pic shows the charcoal canister delete...

Best,

Phil

[jim-clayton]

I finished my EFI wiring today.

Plugged in my stock ECU and the car fired right up.

I sent my EFI to DRS for data logging upgrade. Should have it back next week.


Let the fun begin...

Excellent Jim!

Phil, thanks again for the Delta tune, I have not rec'd my EFI yet. I'll take a look at your tune and compare it to the one Casey is sending w/ the EFI. I can't wait to dive in and begin to tune, a little help is always appreciated. Although, my engine is a bit different and will require some attention due to the new pistons. Iam new to the Lamba tuning stuff, a little more acustom to motorcycle tuning maps which deal only w/ a/f ratios and fuel not much on timing. I should be able to get the a/f pretty spot on, timing will be the biggest issue given iam at 9.0/1 pistons. Anybody have any experience with low comp. piston timing w/ the EFI? Thx, Mike

You'll probably be able to run more advance than the higher comp'd guys. Just make changes very slowly. If you have a chance, try to use an EGT sensor with the wideband...helps when you are getting "close"....

Be good and good luck,
TomK

Ace, What is a EGT Sensor? Where can i pick one up at and for $.

Take it to a tuner or ship it to ForcedFed and have them tune it.

[turbophil]

Same basic rules apply... Tune to get the AFRs right, then tinker with timing, then tinker with AFRs again, as the timing will play with te AFRs a bit... At the end of the day, you'll be running more timing than the map i sent you to get the most hp you can... The map you have won't be waaaaay off (as if you were starting from scratch), but it will need significant adjustment. If you don't know much about tuning, you'll either decide to take it somewhere, figure it out yourself, or blow up the car In any case, I suggest that yet opt for the data logging option. It's something I did not do, but wish I did. You can basically set the tihing to auto tune itself with the data logging option....much easier than the brute force method I used, which consisted of a lot of street tuning, etc...

Best,

Phil

I'm happy for you but ........ that was a killer deal.

And my choice of colors.

And an east coast car.

I'm sure I'l get over it. Eventually.

[Randy Chase]

Damn Jim, I think highly enough of you, that if you had asked, I would have considered letting you take it.

Just considered mind you. And a heck of a lot easier to say now. But I might have...

I can tell you that would like this car. You are kinda going down a path I went, SC with EFI.... a lot easier on the Noble to get power.

Well just to be clear. I saw the thread after you already secured the car.
I'm just jealous that's all.

sorry for the hijack ....

Phil, no worries i will get the afr's tight and have a tuning shop dial in the timing w/ a four or five gas. Then dial the afr's again for good measure, since I don't want to blow this engine again. No drama, and you can rest assured i would never go after someone who is willing to offer free advice.
Thx, Mike

[jim-clayton]

My EFI is up and running. Got a map from Phil and Kris, thanks guys.

The car runs great. I will dyno some day. The ability to monitor the tune is great. Real numbers, not the shady stuff that comes out of the ODBII

The unit paid for itself with one adjustment. Lower rev limit to 8200.

Don't want to drop a valve this month.

[turbophil]

I'm glad you like it Jim. As you know, I have a blast with mine.

I think you're smart to drop that rev limit a bit. You won't win any dyno contest with it that way, but you're likely *not* be buying a new head anytime soon...

I keep telling myself that I'm doing all this work to replace the clutch and perform a needed valve spring upgrade... it makes me feel better that way... I liken it to taking the scenic country roads to get somewhere rather than jumping on the highway...

Cheers, Phil
