Anyone know of a place where i can download a service manual, PDF form perhaps?

I'm getting a signal(12v) to the AC compressor, but from there not to the clutch. Plus i'm only getting one fan when the AC is on (driver side). I can't remember if that is the AC fan and the passenger side is the other, or not.

Got my tach working, thanks to rev and the db37 connector.

Still only have one fan working and no AC. Is it safe to wire both fans into one wire? Mishimoto slim fans. Will i smoke the wiring because amperage?

Finally put E85 in it. Way easier than i expected. I'm tuning using the regular AFR numbers, just because it makes sense to me. Just did the 30% increase to my map and it seems to run just fine. Obviously needs tuning, but drive-ability didn't change one bit.


My laptop keeps going into super slow mode, i'm guessing it's some type of protect so it doesn't overheat. It's too hot for me to be out tuning anyway. This E85 stinks and is giving me a headache.

Wait wut?
You're the first person in the universe I've ever heard say it smells bad. You prefer the smell of pump gas?

I don't prefer one over the other.
They are all equally as bad, diesel, pump gas, high octane, alcohol, e85.
This is my first time dealing with e85 (no one i know personally uses it) so maybe i'll get used to it.

You cant complain about e85 fumes unless you've tuned idle and free rev on a turbo bike motor for it in a garage starting from some tune that probably started out running on the edge of hydrolocking the motor. I can feel my eyes burning thinking about it.

No complaints from me. Simply stating that i've had enough of it for today.

If this fuel preforms half as good as it did today i'll be happy no matter how bad it smells.

Gotcha. Yeah, I hate fumes too, but corn smells 5x better than gasoline

Dafug is wrong with this site? I think it's fucked...

Lets try to post this again.



Put about 150 miles into it yesterday. Was getting some hot restart idle issues when restarted after being shut off for less than 5 minutes... Not sure the issue there.
Did about 30 miles today. A few mexico 2nd through 5th pulls...

So far so good...

I did hear a huge snap from the rear end somewhere. This was during a 1st gear rhomp out of a michigan turnaround. Let off, then got back into it. Everything seemed fine i guess. R1Rs still suck (i can't drive hard enough on the street to make good use of them) i want my Dunlops back.

"CLUNK" is still there when i apply brakes... No idea.

GOTTA do more ducting. She gets warm after hard pulls at speed.

engine mounts tight etc? Must be the driveline moving around surely? Trying to find noises like this can be a right pain in the ***. Hope you get it sorted. The car must be loving the e85

Got the car in the air and i can't find anything wrong.



Reinstalling some heat shielding and ducting.

Have not had an update in a while. Car is doing much better on E85, cold starts are rough but i'm getting that dialed in.

A quick trip to get fuel always turns into a 2 hour blasting session.
Every once in a while i'll take it to work, even though i've been taking the bike a lot.

So i did this earlier.
I know i know, i started at around 3000rpm. Not good for spool data since i'm pretty much in boost instantly.




To lean for E85? I'm guessing that's where the extra HP came from at 13psi.
I've got to tune out the lean spike when i jab throttle between gears.

This is interesting.

Corrected the pull from the other day(SAE) and added it to a pull from today. Did 3rd gear this time for the data.




I am absolutely amazed what a bit of ambient temperature and some AFR does to power.
Imagine if i started poking around on the ignition table.
