The jumper should be removed if you are using pump fuel. I installed a switch so I could easily switch between pump and E85.

Not sure who said an hour to install, took me 30 min to upgrade the A Tune to M Tune.

The MAP sensor install and DME conversion took me about 2 hrs IIRC. Then installing the MAF took about 30 min. About 2-3 hrs total would be a good estimate.

OK, just took first drive, after warming up idle dropped to 1050, about where others reported. Accelerates very smoothly and runs well. Not a huge difference from previous setup, but that was expected. Can't wait for first tank of E-85, that is why I bought it.

The biggest difference is the Sound! If you don't like Ricers you might not like it. I love it though. Turbo spoiling is very loud now and so it drop throttle BOV dumps, sounds like a race car now, hope the cops don't pull me over.

My idle was around 1150 initially in E85 mode, I backed it down a bit to 1050 and it's still there in 93 mode.

The car feels even better now that I'm running the correct mode. It pops more on deceleration, but it's also smoother transitioning off, then back on to the throttle - it was "bucking" just a bit before, probably from being too rich.

Now I wish I had the MBC **** in the car, not under the hood. I'd really like an EBC, but from what I've read, they sound like a nightmare to install.

I have the MBC in the car, threw in three bottles of octane boost and cranked up to 17 for a couple runs. She is pretty fast now, can't wait to see 20! I have big meats on their way here. 295/30 rears, might need them now!

***EDIT***

Looks like you guys got it figured out - sorry, I've been out.
Plug off = pump fuel
Plug on = secondary map

Matt, popping on decel? Double-check your TPS sensor idle circuit is working correctly:

where exactly does the plug go?

Crap - looks like I mis-typed... I edited my post regarding the jumper selection.

zerMATT951

This is what I determined by experiment.

Joshua, my experiment shows the opposite. With the jumper in place, pump 93 octane, I had my FPR dialed back to 32 psi (2.2 bar) and was seeing 10 or less AFR on the WB at WOT & 16 psi. When I pulled the jumper, I dialed the FPR up to 43.5 (3 bar) and now I see 11.5-11.6 AFR at WOT & 16 psi.

Edit: Just saw the corrected post, now everything jives!

I will look a the TPS. I did that test when I rebuilt the TB and got mixed results. I have a spare now, so I'll check that one out.

Matt, you are correct... I edited my previous post.
