No problem. I have a bit more work to do to the map. The WGDC are decent, but still giving me some issues. This thing just creates so much more boost at 10-15% lower WGDC. It is really weird, but then again, this is the first time I have tried to tune for something other than 93 octane gas. I was a little irritated, lol, I had my WGDC all nice and refined and boosting perfect and now I have to redo the whole map. Just let me know. I am available most evenings. Of course it is going to be quite a bit different than the 4eat.
Just out of curiosity, scott, Matt, guys that have some E85 experience, did you run a colder plug or recommend one for E85 applications? I am planning on swapping the plugs here shortly and wanted some input on options for E85. I have heard some mention that a colder plug would be beneficial in avoiding misfires and a colder plug can also produce a stronger spark. Any truth or experience with this?
Well, since I did not hear from anyone on this, I decided to swap out all the plugs and go with stock heat range NGK iridiums. It has not made any difference that I can tell. But then my tune was not at the bleeding edge either.
Finally got mine to the dyno. It rang in at 10 more hp and 35 more torque than last time on a dyno that read less than the one that it was previously measured on. If I had to guess based on numbers from other cars (stock sti and such) on this dyno vs the original one, it would probably be about 25-30 more hp and 45-50 more torque with no change other than injectors and different fuel. So just switching to E85 and tuning for it seems to have made quite the difference in power. I am now putting down more torque than a Stage 1 Sti on a stock turbo 2.0 liter WRX.
Man I just wanted to reiterate how nice this stuff is. I went off E85 for a couple months due to the fact that the station I was buying it at ran out for a couple months. They just got it back in and the car just feels SO MUCH BETTER than it was on gas. And I only put good quality Shell or Chevron gas in it the whole time. On E85 it is just so much smoother and pulls so much harder. My car is happy now :coold:
As an update to this post. Anyone who decides to run E85 REALLY has to watch their gauges. At a minimum I recommend getting a wideband o2 sensor. The reason for this is that from one tank to the next, the percentage of ethanol to gasoline can change quite a bit! I went from my car being perfectly tuned to being 10% lean in one fill up. Why? They switched the ethanol content. There is summer, spring/fall and winter E85 around here. In this recent instance, they went from a winter blend straight to summer. The good part is that the ECU is able to adapt to a certain extent. But you still have to watch and know when to switch tunes!
Something else to take into consideration is that ethanol absorbs more water than gas, and in turn will drastically tweak your numbers. Ask any mechanic that is dealing with the new direct injected engines and how many fuel related failures they have seen as a result. I'll try to post charts form area gas stations around Jim Ellis to prove my point.
