Ok, that makes more sense

So the bad fluctuation is basically the valve bouncing and pressure dropping and spiking over and over again to try and keep up with the loss post valve to hpfp demand. Cool... I know all of my...

So the bouncing pressure isn't a glitch exactly per say. Its a flow problem. Think I said that a while back on a couple, but good to know it could be either and has been confirmed by someone else.

Swaptime makes the best harnesses. Mitch has gone to putting the correct connectors for the different years along with including things such as supply pressure sensors, fpcm's if wanted, the correct...

Yes like Ed said and get rid of the breathers. If you think about it. You have breathers to allow in unmetered air and vacuum being pulled on the valley bypassing the TB that's not helping things....

I also didn't know why the external load was 0ed out? Not sure what affect that would have? I would say fix the vacuum leak caused by the breathers, install the o2s then fix the external load and go...

Last time and the only time I've ever had one do this, it was due to cat lightoff. Due to the 10% lean on the wideband and the - torque at idle, I'm assuming you don't have rear o2's???

Then check...

You most likely did, but did you try without the parenthesis or putting the whole thing into parenthesis while using it in a different equation?

Don't change the throttle max. As long as it was for a gen V, Nick has configured those TB's to flow the same as an LT1 stock TB up to about 30% where you do most of your driving. Just dial in your...

Here you go. They aren't really smooth though. They were shaped off of the VE changes and just worked out that way for this cam. They do curve side to side and vertically. Just keep in mind that...

Double check to see if your zone definitions have been changed under the dynamic tab then it should be the regular 1 bar map config once the ve table is opened.

That huge spike is what I was talking about in my first post

This is a 17 vette I'm tuning right now with the 225 cam, long tubes and a manual tranny.

Without digging too deep, torque model and DD are the big two players. If you have a high stall converter there are a couple of background tables that can cause this in lower gears. I know your VE is...

You're not logging cam counts, but I can tell you straight up every single time I've seen this on a DI engine it was cam related. Even had one harness company pin it wrong and caused a ground leg in...

Last time I saw this it was the cam signal due to the short pigtail on the front timing cover losing connection.

After you fix your injector data and verify fuel pressure (you need something in the 50's), you'll need to set your VE table to read into boost via your boundary settings then tune the VE and your...

Well that's good to know. I know a couple of guys I was doing E tuning on started with around 7 to 9 % then all of a sudden went to 0. Had me wondering if the sensor went out, but found it reading...

You have both moving intake and exhaust cams. Need to use Cringer's VE assistant and work both the coefficients and VE tables at the same time. Normally takes me anywhere from 30 mins to an hour per...

Ve has to be dialed in first. That's what everyone is trying to say I believe. Ve on the v6s is a royal pain. Most likely why it wasn't touched.

:D It's OK Jake. Give it a try on the next big build or different injector engine you work on. You may not believe it, heck it should go against most things we're taught, but it works... I will also...

I'm not talking about controller initiation "hot reflashing". I'm talking about a setting based off of temperature that will directly change the fueling theoretically 4 or 5 % as the engine temp is...

OK, then what's the correct table to use?

May not be viable as in lab settings with a thermocoupler, but it works and it will correct fueling errors for the changing temps ;) I've changed the method a little, but been more or less correcting...

Unless you just run or only have cheaper stations around there, it's more than likely going to be 7 to 9 % ethanol as E10. That's what I see with all of the ethanol tunes I do. It's just stations...
