Looks the same to me.

All GEN4s (except E40) take 4x/58x. Only 1x cam gears for GEN3 and E40s.

7-11 seconds in that log it actually looks like there may be a problem on bank 2. Need a longer data log that 16 seconds to determine.

Judging by the narrowbands it looks plenty rich enough not to be knocking on 97 octane fuel even if it's higher compression. It by no means looks lean.

Put everything you changed under "idle" back to stock. Set the idle speed you want. Up the BRAF a little bit. DON'T TOUCH THE IDLE PIDs!!!

Figure out exactly what injectors are in it. How you...

Cam? Injectors? Throttle body? C'mon man, you know the routine.....

First thing you need to do is rough in the VE/MAF. It's WAAAAY too fat right now to do any idle tuning.

Now it looks pretty normal.

Why? That's exactly what you need to do. Make it buck as bad as you can and point out in time stamp where you feel it. There are 2 timers at the bottom of your scanner. One is real time, the other is...

Put your BRAF ETC multiplier and your throttle follower back to stock. Data log and report back.

I definitely don't like the sound of that. That's too much pressure bottoming out the lifter. No telling how close you are to lifting the valve off its seat. Also, no telling if there's any travel...

Injector data isn't correct and it's not setup correctly for what I assume is a return style system.

If you have the CTSV file open in your compare feature you can see all the differences.

The Baro linear and offset are right above the map sensor linear and offset.

Sorry, not right above....

If you have an automatic transmission you need to start with an auto file.

Or you can segment swap yours. The only reason to do that at this point in the game for you is so you won't have to...

BRAF is way too high for that cam.

Not all the injector data is correct. You only changed some of it.

The Baro sensor is still incorrect.

Any of the stock style lifters, if not limited travel should be fine at 1 turn worth of preload which is almost exactly .050. I think it's .048 actually.

Did you drop in solid roller lifters to check? Install checker springs? If you didn't at least use checker springs it's not correct.

You can't just use the hydraulic lifters and the installed...

That may be your problem. I've seen aftermarket roller rockers cause weird stuff up top. Just like yours is doing. You really can't do much better than stock rockers with trunnion kits for 99% of the...

You need to pull a CTSV file off the repository. Pretty much none of your injector data is correct. The Baro sensor is incorrect. You have WAAAAAY too much idle timing in it. That's about all I...

Post the 2 different tunes and corresponding data logs. No one will be able to tell you anything without them.

It's about the only chemical "fix" I've seen that actually works.

I wouldn't worry about data logging that. Wait until you have something worth logging.

Bone stock VE and MAF tables. IFR has been LOWERED for some reason. Everything about that toon is too much fuel.

All they did was turn off a bunch of codes. It is in no way a startup file for the...

Instead of adding to the startup airflow table you can reduce the cranking fuel. Typically, if it takes more throttle angle to start it's too much fuel, especially with larger injectors.

The just the way it is. You can't modify an engine yourself, then if something happens to it "blame the tooner".
