What was your desired boost % when this happened? I don't see it in the log.

 

Read people... lol

 

I did. I don't think that is his only problem.

 

that's exactly what it was, oil on belt, belt not gripping...low boost lol.

 

It's made multiple successful pulls since i cleaned it up... including some on a 50/50 e85/93 mix ;-)

 

I have seen that happen before. The boost starts dropping off and the desired boost % goes from 100% to like 60%. Once it was related to high IAT2s due to a faulty IC pump.

But I guess you guys got it all figured out and there is no need to look at anything else.

 

No worries man.. I wasn't sure that was the problem until i got it cleaned up myself..

IATs were good 120's when it started dropping boost..

Also the blower snout back to the engine mount was literally dripping in oil.. it wasn't just a misting

 

Will you just check the log to shut me up!?!?

lol

I have seen it before. Once it was the IAT2s. Another time I could not explain it. In the same log, I saw 3 WOT runs that were perfect and 1 that pulled boost.

 

I guess I should add that he posted this with the solution on HP Tuners early this morning, so he knew the answer and all before even posting THIS thread lol.

 

I'll check it out when i get home to my tuning laptop ;-)

 

i was gonna say belt slip, looked like termy with a crappy belt lol... good thing it was something simple!

 

Turns out i wasn't logging desired boost.. *shifty eyes*

I did however get my scanner set up for 50/50 E85 last night w/ proper afr readings and afr error histo's (woot)

 

His IAT2 were fine. I am slightly concerned with the 12.27 afr, and it looks like the graph was leaner before the reading mark and boost loss.... but I did read you were running E85 and found methanol injection in your mod list so i guess that's not so horrible. You probly could make some more torque with a lil more fuel though.

The dipsticks usually don't fly out for no reason... you may be blowing by a little. A compression test may be a good idea

 

I've been playing with different fueling patterns lately.. Lean falling to rich versus flat lines.. Seems to make basically no difference in my times though.. .. I feel safer with a flat setting though.. At the time of this pull it was straight 93 and Methanol, E85 toying just started late sunday night.

I'd definitely blame blow-by for this.. 141k on the stock shortblock, i wouldnt be surprized if the rings starting to leak-by a little (or a lot)..

Its worth noting that i had just changed the oil 20 minutes before.. and the dipstick may not have been seated good, because it's not done it since then..

 

Skip the E85 blending and just run straight E

 

I want it to start on the first try in single digit temps this winter

 

He's too much of a pansy for that....

:shiftyeyes:

 

I hate ju...

This is why I'm going back to premium. Then again, E85 went up to $2.96/gal. There goes the balance between lower mpg and lower cost vs premium

 

hmmmm

Good for you. Keep it safe.

Now is the worst time of year to tune for E85. Stations are switching from the summer E85 to the winter E70. Depending on the station, you could be almost anywhere in between those two blends. E85 is mixed in the tank, not at the pump.

When I switched from E83 to E71 my AFR dropped 1.5-2 AFR in Open loop. Be carefull when it switches back to the spring/summer blends. Your AFR will go in the other direction...

 

Dustin knows his stuff Eric, he's not the typical newb on .net messing with HPT. I wouldn't let my buddy do anything dangerous

 

Take care of that boy!

Are you a male nurse? Or have you been watching this season of TUF?

 

Gotta agree

 

Valid Point

Lets race when you go back on 93

Yeah, I'm aware of the winter mix changes and how this is a really bad time to try and tune this is in.. but.. i was driving home on a road trip.. the station i stopped at had e85.. I had my laptop.. I couldn't resist.... Good news is.. if I stick with the 50/50 mixing, my afr should only move half that much..

awwwwww... shucks Tom..

 

TUF?

Been a nurse for 6 1/2 yrs, since age 18

 

I <3 you buddy. (slight homo intended)
