FA20CLUB.com E85 Goodness
 

We finally got a chance to finish up our E85 tune today. Final results are impressive. We managed to net 20whp over our stock numbers on the AT. Gains will probably be higher on the MT. Mods to the car were as follows

Stock Air Box
Stock Mid Pipe
Stock Exhaust

Car pulls extremely hard. Even harder than what we had last month when we first started tuning. :burnrubber: Unfortunately we had a few other projects we had to finish up before we could get a finalized tune for you guys who have been pm'ing me.

^^^Nice! :eyebulge:

btw Thanks for the updated Tune :thumbsup:

Can't wait to try it out, I'll be in touch for that soon!

Ok, please forgive me but I'm a total n00b to this sort of thing. What exactly is required for this and how do you do it? I come from a computer background and never did too much work on my own cars before, is this like a software flash only or are there hardware changes required? I'm just curious for now, I can't afford to be voiding my warranty just yet but in the future I might be looking to run e85.

Its just an ECU flash :)

Why is your baseline so low?

thats the same baseline we have always used. its a mustang dyno which reads 10-13% lower than a dynojet. So realistically our baseline on a dynojet would be roughly 155whp. some people edit the readout of a mustang to read higher but ours has been the same way for 2 years which guarantees when my customers go on a dynojet they will see an increase of roughly 10%.

I still feel that 155whp is a bit low. I am around 165-168 stock.

Youre in mass so you geographic location yields high nembers come to florida and try making the same power in our heat and humidity. In fact a prime example of this is our stage 2 tune netted only 156whp on my dyno but else where in the country netted almost 180whp. And everyone knows its not the numbers a dyno is a tool the fact remain are the gains not what you start/finish with. If i were on a dynojet the gains percentage wise would have been the same hands down. If i gain 10% on a tune one one dyno i should technically gain the same percentage increase on a different dyno.

I have 2 friends with manuals who have run there cars on dynojets and yielded only 158-160who stock just to let you know what high heat and 50% humidity does to power product in florida. We contend with heat other high altitude.

I didn't dyno in mass, but I get what you're saying. :)

Very impressive gains.

Thanks....Im going to try to see how much more i can get out of the low end on it later on this week.

They are using an automatic too which normally has higher driveline losses than a manual. I think the baseline looks about right, no doubt a manual on a dynojet would have a higher baseline.

Thanks! Got the badges :thumbsup:

Your are welcome sire. I guess the USPS mail system isnt that slow huh...

No USPS has been good to me for the most part :thumbsup:

Great numbers! So will this tune be faster than the E85 that I drove at your shop? That was pretty damn quick already :)

This is probably 5-6whp higher than when you drove it with an extra 2-3tq. Definitely faster than last time.

what knob is that-good looking!

It's starting to cool off here in arkansas, think i would have any problem on cold starts with the E85?

STi TI shift knob, Part # ST350224S000

It was ordered from Japan

Hoping to see E85 in my area in the near future ;)

Nice! Where in FL? I may contribute lol

FA20.club, I am sorry if the information is in an earlier part of the thread, but do you provide periodic updates to your tunes for free as your development of the platform progresses?

Yes, Sir....

How would this tune work out in cold-ass Europe? Atleast for me here in Sweden, we have plenty of E85 but no FRS/BRZ/GT86 tuners who does this :(

So there are no changes other then an ecu flash required for the e85 tune? If so how much is the flash and what measures are needed to get it done?

looks like it's 250 from fa20club for the tune. if you don't already have an ecutek cable/license, you'll also need that.

They have a deal, the first tune is $250 but if you buy a second tune at the time time its $100 and the third, $50. I bought the STG2 and E85 for $350.

I bet it wouldn't take 90 days to get a tune from these guys.

Took 2 days from money paid until tuned including shipping cable across the country.

Best customer service around.

Lot's of happy customers. Good to hear :thumbup:

Im sure we could get it dialed in for you. It would just take some tweaking on our end but nothing major.

Sure wont...:thanks:

Thanks for the support guys....

3.5 gallons of 91 octane before I can try the E85. I'll try to hop on a dyno after that if possible, same one I have my stock baseline.

Do you have a preferred aftermarket intake to work with? I was looking an the Injen since it appears to be the highest rated or maybe a simple AVO silicone design.

Let me know when you are heading to the dyno and ill make sure im available to edit the tune while youre there.

I've been reading your threads and am very interested, but I'm seeing a lot of different information from tune to tune. Your stage 1 tune says it made +12whp on 91/93. Your stage 2 tune says it makes another 5-7 wheel horsepower over stage 1 with just an aFe intake. So am I to understand that your E85 tune gaining 20whp is about the same gain as stage 2 on pump gas with an intake? Also, these are just peak horsepower gains... I can't find dynos of stage 1 and stage 2 to see how power and torque compared to stock across the rev range. If I'm missing these dyno charts please link. I'm most interested in the stage 2 and would very likely join your group buy if I could see a dyno chart showing stock baseline vs stage 2 with aFe.

Our E85 tune was tested on our stock configuration AT FR-S. We netted 22whp. We usually leave our car in stock most of the time for testing new products. We have had a quite a few companies and customers send us products to dyno test. We have not tested the E85 tune personally with any intakes but currently have customers with that combination that we are in the process of refining the tune at sea level and 5k ft above sea level to provide great starting points for others interested in purchasing the tune.

Another member tested his stage 1 with afe and netted 178whp on our stage 1 tune. The results were posted in the forum user name mechaghost i believe. This is what lead to the stage 2 tune development because the intake created some lean spots that we corrected with the stage 2 tune. So thats a good starting point. He also tested the airaid and you can see how problematic the getting a stead afr was vs. the aFe. PM or email me if you have any other questions.
