If its not too much trouble, yea shoot me your config file so I can plagiarize it.

**Murlo26** · 10-07-2011

Got the wideband working for logging now too, yay. Thanks again Scheides.

Also, I sent you a few logs Scheides, ones I just took over lunch.

Good job, if I woulda seen this earlier I coulda helped, I have all the soldering junk already.

No biggie, now I have it all for future projects so its all good.

The install wasn't too tough, just awkward and the whole no light and doing stuff in the driveway with jackstands really slows it all down.

Maybe next time I have to do something I'll bug ya

Not much of an update, but the car is up at DB right now and no idea wtf is going on with it now.

The serpentine belt was rubbing pretty bad and frayed so they replaced that but I had gotten a knock sensor code as well so I wanted that looked into as it scared me a bit.

They didn't see any reason why the belt was rubbing I guess so we will see where that goes after more driving. The knock sensor code pops up 50% of the time now on startup (so every other startup) Shane said so I went ahead and ordered a new sensor two days ago so we can confirm the sensor is working. I guess Shane said he had been seeing some crazy counts from like 9 counts to 0 to 9 back to zero or some crazy shit.

I am hoping nothing is wrong with the motor itself and its something stupid like fuel pump or MAF or something. ERL has had a few problem motors lately popping up in threads with people having to pull them and send them back but those were strokers not overbore motors like mine.

Once we can confirm the knock sensor is working we are going to start trying things like blocking off my second fuel pump on the double pumper and putting the stock intake back on too for scaling the injectors better and what not.

Sigh, i was really looking forward to some peddle mashing, I think i have only had one clean pull since I got the car, maybe two. As we are getting these weird things a bunch. The joys of a built motor I guess.

Shane has been pretty good about helping out though and I thank him for that.

One thing I am going to have him try after talking with a few gurus and AMS is collapsing my high octane and low octane timing tables. Apparently that really helps with these crazy knock occurances. I hope that wasn't the problem though and that my knock sensor is in fact bad. With the code I can't imagine that something isn't wrong with the sensor itself as everyone I talked to said they have never seen this code. Especially since its the same sensor that took a blow from the rod on my first motor. DB checked it on my first motor build and it appeared to still be working.

I am so so tempted to dump this car and pay off debt, that sounds like way more fun to me. Not sure if its just my luck or if built motors just require that much extra nonsense to keep them up to par.

It sucks you are having such a headache.

A//// Guy · 10-21-2011

That sucks, time to dump it.

Maybe its Friday but I have a re-newed sense of sticking it out today haha.

Dumping it would be me losing my ass on the car, so I will give it a little more of a chance.

It's winter basically now so I won't be driving it for a while but I just hope I get time to figure some shit out on it.

**Murlo26** · 10-21-2011

Also the last WOT pull I did seemed pretty damn good (this is the night before I got the knock sensor code which prompted a trip back to DB).

So I think with a little fine tuning and figuring out the stupid knock sensor code (hopefully a new knock sensor fixes it), the car should be pretty good. I am just worried that the car might have a real mechanical issue, but who knows.

turbotalon1g · 10-21-2011

I'm not sure what shane tunes your car too, but it looks like its rich to me for e85.

I usually tune my car on E85 and once the mix is down to E70 or whatever u have it will go richer.

My timing is about the same too.

Good luck figuring it out man, i hope its nothing serious if anything at all.

Also are you filling up at the same stations all the time? I always seem to, but i prefer holiday stations apart from the one on 35w and lexington that one hates me.

It is a bit rich for sure, I was going to have shane lean it out to at least 11.5 or so. Most people shoot for 12-12.5 on E85(E70). So even 11.5 is a bit rich still, but not quite as bad as it is now. A few people said I would get rid of those 1's and 2's of knock count with leaning it out a bit.

Yes, I fill up at typically one of two holiday stations. One on central and 99th st is my main one. The other is near my work in plymouth, not too far from MAP.

The only thing I am worried about now is the seemingly random knock counts Shane told me about and the fact I get a ton of knock sensor codes. Hopefully a new sensor fixes it all and yay we are good to go

With all this talk about knock...reminded me a bit of this, and well its Friday..

You are so close to finally rolling, don't get too discouraged .. you are a trailblazer.

Every car I've tuned is different. My old car liked it lean this one, I haven't figured out yet, she's a bit of bitch.

I am trying not to, just trying to stick it out.

We will see what happens here. I think a little leaner will clean it up a bit.

**Murlo26** · 10-27-2011

New knock sensor came in yesterday. Stopping at DB over lunch for a few minutes to drop it off and get their thoughts on everything.

**Murlo26** · 10-31-2011

Shane emailed me before he left today, the car is still on the dyno right now.

It sounds like the knock sensor code is no longer there!

He said the big knock counts are gone too that he was seeing. He adjusted the fuel controller to bring the second pump on sooner and apparently that helped quite a bit. He said he was going to do more low load/boost and transition area tuning tomorrow it sounds like and then drive it on the street. Sounds like it is getting damn close now, yay.

**Murlo26** · 11-01-2011

Going to pick the car up shortly, Shane said he finished up the touch ups. Woo

Still no snow out either, so I have a few days to drive it at least.

93gtpeater · 11-01-2011

Hopefully when spring comes you can actual drive it and in joy the dam thing. I give you props for sticking it out. anyways glad your getting it back before it snowed out.

turbotalon1g · 11-01-2011

Nice.

Knoxville · 11-01-2011

Did you take it out for a spin? Any initial feedback?
