Hal only made a lil over 620s with 1200s on E85. I'd go straight to 1600s

 

Which 1200's were they though?

Most of the old 1200's only flowed 1080cc......but the new ones are actually flow 1200cc.

Well, if it matters, Larry just put 1200's in my car. They are Delphi brand injectors.
He recommended them and I am following his every recommendation.

 

Those are the new ones that actually flow 1200cc's

tom

 

which ones were 1080, RC's or PTE, or..???

well make sure to post your IDC with that 750 hp sheet. be great info as IDC is hard to come by with 700+ hp cars

 

Injector Duty Cycle......will be a question for Larry

Tom

Str8, I think it was the RC's but I'm not positive....lemme check

 

this site seems to suggest Delphi,PTE, RC are the same parent injector and they just rebadge

pretty sure thats true, but not so good if people said the RC's were only 1080cc. Thats why I asked.

Not that it matters to me as I am trying to sell my HKS1000's since those are even too much

 

>1% and <99%

no clue, Larry Prebis question lol

Tom

 

The RC 1200s only flowed 1080, we flowed the new Precision ones and they actually flowed 1280!

 

I'm hoping the Delphi's are in the same boat? pushing close to the actual 1200cc's...

Edit...nvrmnd. just read the link above. I know it flows as well. Thanks for posting.

 

I can't wait to get Tom and Ryan's cars with this setup!! Of course my own would be nice too...

So in the video, the supra is only seeing around E75. What is the typical ETOH concentration when you tune? Do you only run full tilt boost/timing when the gauge reads E85 or above?

What about cars only running E85 without a visible numeric value (ie CAN gauge or zeotronix gauge)? At what % of ethanol do you/proefi start backing down the tune?

At what ETOH percentage does the AFR start to effect drivability due to AFR changes?

 

I noticed absolutely no drive-ability changes regardless of what the ethanol % was. Whether it was 85% or down to 9% after filling up with 93 pump gas....The tune adjusted seamlessly. Car still idles and drives beautifully.This is just my experience. I'll let Reid or Larry answer.

 

so does the flex fuel sensor come with the 128 or not? 500$ for a sensor seems retarded

 

No it is not included. It is $499 IIRC, and you will need it with either the 48 pin or 128 pin is so you can monitor your ethanol percentage. Or any EMS for that matter.

 

So your full boost tune was done on 50% ethanol? does it up the boost/ timing when it sees E85 or can it only interpolate between your pump gas tune and your ethanol tune (E50)?

Along those lines, the IPW to idle E85 vs E50 would be quite different, have you watched to see if there was any difference?

 

hmm, well that puts a hold on my plan. Advertisement on that needs to be adjusted accordingly. It says "128 pin will monitor e85 levels and adjust the tune with no additional software, 48 pin requires gm flex fuel sensor and zeitronix gauge in addition to monitor e85".

So it makes it sound like you only need to buy the sensor with the 48 pin. How the hell is a simple sensor like that 500$?

 

you have to have the sensor for either EMS. The 48 pin also need the Zei ECA gauge because it has to have the 0-5V analog out. The 128pin can read it directly off the sensor.

The gm sensor from the dealer is almost 700$ brand new. They are lucky they sourced ones for that cheap.

not to mention this
*It has been tested and proven that a car that would get 19 city/21 Hwy using normal gas (regular), would get 9 city/11-13 hwy using E85. (from http://www.juliantrubin.com/encyclop...oline_e85.html)

 

i believe they mentioned it in the thread, but yes, you need the sensor either way.... with 128 you just don need the gauge to monitor.
As far as cost, well if you look it up in a dealership you will see how much higher it is. and also putting it in perspective with
reliable systems
http://www.importpartspro.com/niin4.html
or
http://www.aqmotorsports.com/aquamis...em-p-2669.html

and consider that none of those come close to the benefits of e85 and reliability, and also those kids are just increasing the number of parts that can fail or have a bad install, etc...
at the cheapest, we are talking 100 bucks more over the snowperformance setup...
Of course, this is with the assumption that you are a high whp build and 128 pin is already in the bank....

 

haltech is already in the car, i was looking for a reason to switch but i can run that sensor anyways and monitor it myself and then just change my map back to pumpgas if i had to fill up on pumpgas. so basically, 500$ plus the cost of the ems to upgrade from my haltech when it's not much of an upgrade. If it did all that on it's own then i would hands down switch without a thought. The point of wanting to switch was to keep from having to purchase the 500$ sensor so i guess that rules out that.
