Todd provided me with a E85 tune running on stock injectors with an upgraded
5 Bar FPR.

Wow, what can I say car runs smoother and pulls harder.

Did a brief data-log on the drive back home and my timing is twice better
then the 93 tune at given rpm/load. Was in single digits now is in the teens.

Third gear pull and I backed off at 4500 rpm.

Will be doing some more testing to see when we max out injector duty cycle.

I will be dynoing the car in a few days and will post the results.

 

In one of your sigs it says you have a giac tune, did you change to the proto or am I looking at the wrong car?

 

I had a Softronic tune, changed to Protomotive\Softronic.

Todd is a great guy, very knowledgeable/helpful.

 

Todd is the man !

 

If you have this e85 tune and your going on a trip and there is no e85 station around, can you run regular gas if you had to?

 

Hmmmm...did you ever have the giac tune from Champion?

I know that Todd rocks, there's a Proto tune in my car.

 

Todd provided me a 93 Tune with 5 Bar FPR and I can flash to when I don't want to or can't run E85.

 

Never had a GIAC tune.

 

Does the tune upload just with a laptop and inet connection?

 

Yes, I have done it next to Barnes&Nobel using their free WiFi.

 

Nice! Thanks for the info!

 

Asked Todd the question of running 93 Oct on E85 tune and his answer is
" the answer is yes. It’ll adapt, not ideally, but just in case, you can.
I’ve expanded the range that the O2’s can compensate from about 20% stock to nearly 40% now, just in case you needed to run 93 for some reason and couldn’t flash back".

He thinks of everything a fantastic tuner.

Way to go Todd.

Guys with E-85 availability should definitely go for this tune.
Stock injectors with 5 Bar FPR.
DIY on swapping out the FPR can be found at

Race gas at $2.24 instead of $10.30.

 

nice write up,ven, thanks for nudge over to proto...rep points to u

 

It's good to know that you can fill with pump gas in case of emergency but pushing the O2 sensors to 40% is really a stretch. The system will be constantly trying to compensate. At least you would error on the rich side. Just don't push it.

 

Todd provided a revised tune based on the data-logs provided to him.

Todd felt there was room still left with fueling permitting new tune
set for 1.3 Bar(19+ psi) Standard and 1.5 Bar(22+ psi) Sport mode

Look at the numbers on my standard run, timing holds steady @17.25
under max boost 19+psi and load 218.

Folks with access to E85 now you can run E85 with out upgrading
injectors, it is like running race gas see my timings above
