JZW This makes me wonder if its true that less fuel is needed to make the same power at elevation. I am sure my dc is high, but really don't know how high it is right now.

The other draw back is that if you ever want to travel somewhere, the issue of finding e85 can be a real one.

I might just stick with 35% e85 to keep my octane up, egts a little lower and give myself a little more knock protection. The car is going faster on the clock and I want to get back on the dyno and see what it says about power and torque...

Depends on what "real" power level you aim at, but currenty I personally for instance dont have too much DC to spare with normal fuel and 750CC's (DC ~95%). Increasing the fuel flow by 40% from the current level would require bigger injectors and pretty much the whole fuel side (rail, lines, pump etc).

Thanks

Yes, my E85 car is an '01 viggen. The ecu is just a T7 that Taliaferros tuned for me, plug and play. Nick's custom flex from the Nordic boys. I'm certain he can provide the same SW for your application. I can't say enough good about it, truly a beast. I'm fairly sure it's about to the point of "better not miss shift" to keep my gear box happy.
Oh, and the SW worked very well with or without the T5 cams, I liked them both for different reasons.

Its just about done, it should be available soon. There is quite a few more maps that is for sure.

I have been talking about these things in t5 for so long it all seemed familiar to me and I seem to have a natural knack for tuning. I knew all the tuning priciples and theory and just had to put them to use. It just takes time and the easiest thing to do is look at stock files and tuned files and see what people are doing to the boost, fuel, knock and timing maps...

There is quite a few maps to be delt with, but if you are tuning yourself, all the information is in the manual

lms I talked with Nick about this in regards to my viggen (18T) , and it is not plug and play at all with staged ecu's. There is a hell of a lot involved in regards to our cars. I asked him about the injectors packs they sell, and if you have a stock car then it should work, if not then do not do it as the car would have to re-mapped and there isn't any off the shelf tunes for this yet except maybe maptun.
Hawaiian-what stage do you have?
07-09-2008 06:45 AM
nbndtrain My understanding of the E85 flex fuel tunes is that on gas, with your current hardware, you would have a stage 3+ and when you fill up with E85 you would be around stage 4 power. The Nordic E85 Flex Fuel tunes at that hardware level might require both injectors and 3.5 bar FPR becuase of this. Bottom line, ask Nick.

2k193turbo E85.
07-09-2008 03:48 AM
stevehayes01 E85 can make good power but it takes allot different fueling to get the same power out of the car as it would on a normal gas tune.


I agree with HawaiianSAAB and that if you are going to go with an e85 tune make sure that you get one that is a flex tune.
07-08-2008 07:38 PM
HawaiianSAAB For sure call Nick T. I'm loving my set up and other than the turbo my 01 vig is set up close to yours. You can run a flex program that will allow you to run gas also.
Anyway, for what it's worth I really saw a nice difference with the flex program, running with E85.

Viggen Crazed most gas stations have it theres 4 gas city's within 1 mile radius of my house and each have e85 and race fuel

drewz airflow se how available is e85 where you live?

Viggen Crazed
e85 or 92 Octane

I have a 2001 Viggen, with the following mods; 3in dp, cobra intake pipe, new td04, intake, 2.5in exhaust with straight intermediate pipe, ETS intercooler. I'm thinking whether i should get the 3.5 bar fuel pressure regulator and go stage 4 ECU or some injectors and go e85 stage?? What would you guys suggest
