Yep
I?ll check for vacuum leaks again tomorrow. I just have to assume that it?s tune related because the truck ran great before
I thought I had a win for a minute earlier. I upped the injector size to 26lb/hr and it was actually idling! I don?t know what injectors are in this thing so I was just trying shit. But the engine...
It ran fine and didn?t have those codes before. And I can?t fix the crank sensor code until it?s running better because it?s impossible to do the relearn like this
To be honest, I?m not sure if the injectors are the same as what?s in the tune. As far as I know there?s nothing done to my engine besides the short ram and cat back, and it?s a low mileage crate...
Hey strangers. I've got a 97 Vortec 454 stick shift 4x4 truck. Only engine mods are a short ram intake and cat-back exhaust, nothing major. I just did the 0411 PCM swap this week. I'm having issues...
Hey guys. Forgot about this post there for a bit. Im glad to say I fixed the issue. I finally got around to wiring my wideband into a serial port so I could datalog it and therefore tune my VVE and...
As I thought, it didnt work. Honestly I think the torqe demand being higher than delivered isnt really an issue especially when its within 20-30 of what the car is actually making. I agree that the...
I went ahead and changed that one. If it made a difference I cant tell. The desired boost is dropping all the way to 15psi from 23-24. No significant knock or anything. If you look at my timing...
Okay scratch all that. I just tried it and it seems to have helped for sure. I thought that boost test made the driver demand map irrelevant, but apparently not. I disabled the boost test and...
I will give it a shot. But Im gonna go ahead and mention that its never been a problem before. It only started happening when I brought the boost up over 20psi. I ran around with the boost test set...
I shouldve mentioned this in the OP, but the issue isnt at all times. I can free rev all the way to the 6500 limiter with zero issues. Also, if the wheels are slipping pretty aggressively, itll go...
Unfortunately guys it was neither of those things. No change at all
Cobalt, I have messed with that table before a little. If the accel thing doesnt pan out I will check into that again.
Scarab, I saw that before and wondered if it would ever be a problem, but didnt really understand it. Can I just zero the table out so it cant limit based on acceleration at all?
Hey dudes. Working on my Soinc tune right now and I cannot for the life of me figure out this issue. Ive ran into it a couple times now. The car is pulling pretty good, making some steam, and then...
Did you wire your wideband through the egr, or do you have a pro model? I can?t find a Sonic E78 ECM pinout, just trucks which don?t have egr
My tables did work. Its not perfect, but its definitely better. Check it out. I basically disabled all of the fancy idle stuff by zeroing out the tables and maxing out the enable/disable values. Of...
Well as much as I?m peeved at zzp, they are the only ones making cams for the 1.4.. Im just kinda seeing what the stock turbo can do, and when it starts to give out Im gonna make my own manifold and...
Thank you for that link, it was helpful. I have gotta get my wide-band signal run through my EGR before I can really tune the MAF. I did not realize doing that would be basically necessary. As for...
Sorry, did not realize that the tune was not attached the first time. Here is my latest tune with the 40 kpa throttle blade pressure drop. I know the file name says psi but its in kpa. I guess I need...
I have noticed that the boost is going down over 5k rpm because the actual desired boost is going down. So, its definitely not mechanical. I am trying to figure out whats causing that. Been changing...
Log file. Only difference from the tune file is I enabled no lift shift. As you can see by the name, I put some pre load on the actuator trying to hold boost in the upper rpm. Did not change...
Hey dudes, I would like some help with my LTFTs. So far to make power all I have done is command more torque above high throttle percentages and adjust things like boost and torque limits that got in...
