Think you nailed it Johan

Got the 1000cc injectors in the V, along with the tune you wrote for them. Runs smoother now then it ever has, and isn't falling flat on its face at high rpms any more. Awesome.

I'll run a log tonight, but I'm not expecting to see anything out of the norm. Feels really good.

Now to figure out how to get the power down so I can add some more. :drivingbad:

Here's a log. Sorry I couldn't hit WOT. When the boost hits, it feels like you're being kicked in the stomach. And the speed rises in a hurry, so keeping my foot in it isn't possible. Think I hit about 90 in a 35 for this log.

Kinda worried about that KR. Same as what happened on the last log. It goes rich and knocks. If its knocking now at 13.5psi, its gonna get really bad when I swap the upper pulley and go to 18psi. Think I should do Meth injection? The gas seems to be the main problem, but I don't have a solution. I've logged with BP and Exxon and both had the same result.

EDIT: Made some changes to the RPM limit in gear, shift points and shift pressures. I'll get a log of all that later.

you plan to get 5 more PSI from an upper pulley swap???

I bet he can clean the KR up...

Did you have a wideband on that thing, if so what does it read?
I tweaked the file a tad here, looks like it might just be the ramp in causing the knock but give this file a shot here and let me know how fueling looks.

I'm thinking about 4.5psi. Most are showing 4psi from a 2.55" pulley, and I have a 2.38", so it'll be a bit higher.

I don't have a wideband. I wish I did, but theres no place to mount a gauge. Autometer already turned me down for a pillar and pod mount. Is there such a thing as a wideband that has no gauge but just an analog hookup so I can plug it into the Trinity?

I'll try this file tonight and see what it shows. Thanks Johan.

Ah ok, well let me attach this one also, added a little fuel in boost here.
What about innovate or zeitronics, i am sure either of those would let you get just the sensors .

Post by **mikel** » Wed May 23, 2012 6:10 pm

Yeah, pretty sure you can get the innovate with no gauge...and the gauge they do sell is almost flat.

Yep, Innovate has the LC-1 without a gauge. And they're pretty cheap. Guess I should probably buy one to be safe. Rather spend $168 on a wideband controller then $15,000 for a new motor.

Weather didn't cooperate, so I didn't get a chance to log. I think there might be a slight problem with the one without fuel added though. Its idling kinda rough. Rough enough that you can feel it through the steering wheel. May just be the computer adapting, not sure. I left it on, so I guess we'll see what happens.

Mike_Levy · Post by **Mike_Levy** » Mon May 28, 2012 8:00 pm

Okay, both of these logs are with the first updated tune w/o the extra fuel. First one something got screwed up. I think I rammed the rev limiter, because she started stuttering like crazy (plus she went to 6700rpm!). Second one felt clean, but she didn't rev as high as I wanted it to.

LTFTs stayed negative the whole time. Should I try the one with added fuel or hold off for now

Also a minor issue, but every once in a while she won't start immediately. She has to crank a few seconds before it catches. Not sure if its tune related or not. Assume its related to not getting fuel or getting too much fuel or something.

johan · Post by **johan** » Wed May 30, 2012 4:03 pm

Ok, wot did not look bad at all, might be a little too rich but i would almost rather keep it like that for now, i cleaned up part throttle and adjusted some crank fuel here.

Mike_Levy · Post by **Mike_Levy** » Wed May 30, 2012 4:08 pm

What was that stuttering/glitch in the first log? Kinda freaked me out when she had a fit.

EDIT: And I just got the PCM Unlock (-1) error. Restarted and it took the tune. Something ain't right with this car.....

Drove it for the first time tonight. Something's wrong. She's not engaging the tranny right at low speeds and she feels very sluggish. Went to make a right turn going about 15mph and gave her gas, nothing for half a second then it grabbed the gear and jerked. Same thing happens when slowing for a light and then hitting the gas when the light changes. If its not stopped, nothing and then it goes into gear and jerks.

I need to relog this. I hope I didn't break something by overrevving it. Doubt it, but I guess its possible. Motor is only rated to 6600 and I went 104rpm beyond that.
